-
-cexcept (pronounced "see except" in English) is a package providing
-a Try/Catch/Throw exception handling interface for ANSI C (C89 and
-subsequent ISO standards). It does not attempt to handle system
-exceptions like floating-point exceptions or addressing exceptions, nor
-compiler-generated exceptions like C++ exceptions; it is intended as an
-enhanced user-friendly alternative to setjmp() and longjmp().
-
-The package consists of the following files:
-
- name version
- ---------- -------
- README 2.0.1-optipng
- cexcept.h 2.0.1-optipng
- example1.c 2.0.0
- example2.c 2.0.0
- rationale 2.0.0
-
-The package is both free-as-in-speech and free-as-in-beer:

- only if accompanied by this unaltered notice. Subject to those
- restrictions, permission is granted to anyone to do anything with

- this package, and are not responsible for any damage resulting from

-
-The version number of this README file can be considered the version
-number of the whole package.
-
-The file cexcept.h contains the documentation and implementation of the
-interface. The other files are supporting documents.

-Here is another place to obtain the package, not guaranteed to always
-have the very latest version, but probably more highly available:

-
-The remainder of this file is a log of changes.
-
-
-2011-Jul-22-Fri
-
- cexcept.h 2.0.1 --> 2.0.1-optipng
- * Made exception__prev volatile to avoid "variable might be clobbered
- by longjmp" warnings when a function contains multiple Try blocks.
-
-2008-Jul-23-Wed
-
- cexcept.h 2.0.0 --> 2.0.1
- * Clarified the license.
- * Reworded the introductory comments.
- * Bug fix: The statement following Try could not be an if-statement
- (without else); the Catch would then be parsed wrong.
- * Quieted a new warning in gcc 4.2.
-
- README 2.0.0 --> 2.0.1
- * Reworded the license to agree with cexcept.h.
- * Updated the URLs.
-
-2001-Jul-12-Thu
-
- cexcept.h 1.0.0 --> 2.0.0
- * The documentation had neglected to mention that the Catch
- expression was evaluated before the Try clause was executed.
- Rather than document this unintuitive behavior, we have changed
- the interface so that the Catch expression is not evaluated unless
- and until an exception is caught. This change will not affect
- applications that never used Catch expressions with side effects.
- * The implementation had been technically incorrect because it
- modified the object named by the Catch expression between the
- setjmp and longjmp calls, even though it might be a non-volatile
- automatic object (which it was in example.c). The problem (which
- affected no known compilers) has been corrected by performing two
- copies: first into volatile temporary storage before the longjmp,
- then into the Catch expression after the longjmp.
- * The requirement that the Catch expression have the "exact same
- type" that was passed to define_exception_type() has been slightly
- relaxed to disregard type qualifiers.
- * In the license, "no guarantees about the correctness of this file"
- has been changed to "no guarantees regarding this file".
- * Notes have been added that "real" exceptions are not supported, and
- the size of the exception type has performance implications.
-
- rationale 1.0.0 --> 2.0.0
- * Removed the obsolete question about why the Catch expression is
- always evaluated.
- * Updated the answer to the question about the type of the Catch
- expression, to correspond to the new implementation.
- * Added a question about why two copies are necessary.
- * Added a question about why "real" exceptions cannot be caught.
-
- example.c 1.0.0 --> example1.c 2.0.0
- example2.c 1.0.0 --> 2.0.0
- * Renamed example.c to example1.c.
- * Changed the version number to agree with cexcept.h in the first
- two places (2.0.*).
-
- README 1.0.0 --> 2.0.0
- * Reworded the license to agree with cexcept.h.
- * Changed the version number to agree with cexcept.h in the first
- two places (2.0.*).
-
-
-2000-Jun-21-Wed
-
- cexcept.h 0.6.1 --> 1.0.0
- * Changed the version number to indicate stability.
- * Changed "an lvalue" to "a modifiable lvalue" to agree with the
- language in the ISO C Standard.
- * Added hints about dealing with the inability to return from a Try
- clause, and with automatic variables modified within a Try clause.
- * Clarified the restriction on Throw'ing a comma-expression.
-
- example.c 0.6.0 --> 1.0.0
- * Changed the version number to agree with cexcept.h in the first
- two places (1.0.*).
-
- example2.c 0.6.0 --> 1.0.0
- * Changed the version number to agree with cexcept.h in the first
- two places (1.0.*).
-
- rationale 0.6.1 --> 1.0.0
- * Changed the version number to agree with cexcept.h in the first
- two places (1.0.*).
-
- README 0.6.3 --> 1.0.0
- * Changed the version number to agree with cexcept.h in the first
- two places (1.0.*).
-
-
-2000-Apr-22-Sat
-
- cexcept.h 0.6.0 --> 0.6.1
- * Clarified that the wrapper .h file is needed only when there are
- multiple .c files.
-
-
-2000-Apr-08-Sat
-
- rationale 0.6.0 --> 0.6.1
- * Added rationale for disallowing jumping in/out of Try clauses.
- * Expanded the discussion of finally clauses.
- * Added rationale for the lack of expressionless Throw.
-
-
-2000-Apr-07-Fri
-
- Created README, which incorporates changelog.
-
- cexcept.h amc.0.5.3 --> 0.6.0
- * The expression passed to Catch must now have exactly the same type
- passed to define_exception_type(), and it is always evaluated
- exactly once, regardless of whether an exception is caught.
- * Added Catch_anonymous.
- * Changed init_exception_context() to take an argument, and to be
- optional for statically allocated contexts.
- * Clarified allowable exception types, added examples.
- * Clarified the restrictions on jumping in Try/Catch statements.
- * Reworded some other parts of the documentation.
-
- cexcept-example.c amc.0.5.0 --> example.c 0.6.0
- * Now uses the 0.6.* interface, and demonstrates Catch_anonymous.
-
- cexcept-example2.c amc.0.5.0 --> example2.c 0.6.0
- * Now uses the 0.6.* interface.
-
- cexcept-rationale amc.0.5.1 --> rationale 0.6.0
- * Added rationale for the new Catch expression semantics.
-
-
-2000-Apr-01-Fri
-
- cexcept.h amc.0.5.2 --> amc.0.5.3
- * Eliminated a compiler warning about an uninitialized variable.
- * Improved the documentation of allowable exception types.
- * Added advice about using a macro for the_exception_context, and
- changed the example accordingly.
- * Improved the documentation regarding jumping out of Try and Catch.

-
-An interface for exception-handling in ANSI C (C89 and subsequent ISO
-standards), developed jointly with Cosmin Truta.
-
- Copyright (c) 2000-2008 Adam M. Costello and Cosmin Truta.
- This software may be modified only if its author and version
- information is updated accurately, and may be redistributed
- only if accompanied by this unaltered notice. Subject to those
- restrictions, permission is granted to anyone to do anything
- with this software. The copyright holders make no guarantees
- regarding this software, and are not responsible for any damage
- resulting from its use.
-
-The cexcept interface is not compatible with and cannot interact
-with system exceptions (like division by zero or memory segmentation
-violation), compiler-generated exceptions (like C++ exceptions), or
-other exception-handling interfaces.
-
-When using this interface across multiple .c files, do not include
-this header file directly. Instead, create a wrapper header file that
-includes this header file and then invokes the define_exception_type
-macro (see below). The .c files should then include that header file.
-
-The interface consists of one type, one well-known name, and six macros.
-
-
-define_exception_type(type_name);
-
- This macro is used like an external declaration. It specifies
- the type of object that gets copied from the exception thrower to
- the exception catcher. The type_name can be any type that can be
- assigned to, that is, a non-constant arithmetic type, struct, union,
- or pointer. Examples:
-
- define_exception_type(int);
-
- enum exception { out_of_memory, bad_arguments, disk_full };
- define_exception_type(enum exception);
-
- struct exception { int code; const char *msg; };
- define_exception_type(struct exception);
-
- Because throwing an exception causes the object to be copied (not
- just once, but twice), programmers may wish to consider size when
- choosing the exception type.
-
-
-struct exception_context;
-
- This type may be used after the define_exception_type() macro has
- been invoked. A struct exception_context must be known to both
- the thrower and the catcher. It is expected that there be one
- context for each thread that uses exceptions. It would certainly
- be dangerous for multiple threads to access the same context.
- One thread can use multiple contexts, but that is likely to be
- confusing and not typically useful. The application can allocate
- this structure in any way it pleases--automatic, static, or dynamic.
- The application programmer should pretend not to know the structure
- members, which are subject to change.
-
-
-struct exception_context *the_exception_context;
-
- The Try/Catch and Throw statements (described below) implicitly
- refer to a context, using the name the_exception_context. It is
- the application's responsibility to make sure that this name yields
- the address of a mutable (non-constant) struct exception_context
- wherever those statements are used. Subject to that constraint, the
- application may declare a variable of this name anywhere it likes
- (inside a function, in a parameter list, or externally), and may
- use whatever storage class specifiers (static, extern, etc) or type
- qualifiers (const, volatile, etc) it likes. Examples:
-
- static struct exception_context
- * const the_exception_context = &foo;
-
- { struct exception_context *the_exception_context = bar; ... }
-
- int blah(struct exception_context *the_exception_context, ...);
-
- extern struct exception_context the_exception_context[1];
-
- The last example illustrates a trick that avoids creating a pointer
- object separate from the structure object.
-
- The name could even be a macro, for example:
-
- struct exception_context ec_array[numthreads];
- #define the_exception_context (ec_array + thread_id)
-
- Be aware that the_exception_context is used several times by the
- Try/Catch/Throw macros, so it shouldn't be expensive or have side
- effects. The expansion must be a drop-in replacement for an
- identifier, so it's safest to put parentheses around it.
-
-
-void init_exception_context(struct exception_context *ec);
-
- For context structures allocated statically (by an external
- definition or using the "static" keyword), the implicit
- initialization to all zeros is sufficient, but contexts allocated
- by other means must be initialized using this macro before they
- are used by a Try/Catch statement. It does no harm to initialize
- a context more than once (by using this macro on a statically
- allocated context, or using this macro twice on the same context),
- but a context must not be re-initialized after it has been used by a
- Try/Catch statement.
-
-
-Try statement
-Catch (expression) statement
-
- The Try/Catch/Throw macros are capitalized in order to avoid
- confusion with the C++ keywords, which have subtly different
- semantics.
-
- A Try/Catch statement has a syntax similar to an if/else statement,
- except that the parenthesized expression goes after the second
- keyword rather than the first. As with if/else, there are two
- clauses, each of which may be a simple statement ending with a
- semicolon or a brace-enclosed compound statement. But whereas
- the else clause is optional, the Catch clause is required. The
- expression must be a modifiable lvalue (something capable of being
- assigned to) of the same type (disregarding type qualifiers) that
- was passed to define_exception_type().
-
- If a Throw that uses the same exception context as the Try/Catch is
- executed within the Try clause (typically within a function called
- by the Try clause), and the exception is not caught by a nested
- Try/Catch statement, then a copy of the exception will be assigned
- to the expression, and control will jump to the Catch clause. If no
- such Throw is executed, then the assignment is not performed, and
- the Catch clause is not executed.
-
- The expression is not evaluated unless and until the exception is
- caught, which is significant if it has side effects, for example:
-
- Try foo();
- Catch (p[++i].e) { ... }
-
- IMPORTANT: Jumping into or out of a Try clause (for example via
- return, break, continue, goto, longjmp) is forbidden--the compiler
- will not complain, but bad things will happen at run-time. Jumping
- into or out of a Catch clause is okay, and so is jumping around
- inside a Try clause. In many cases where one is tempted to return
- from a Try clause, it will suffice to use Throw, and then return
- from the Catch clause. Another option is to set a flag variable and
- use goto to jump to the end of the Try clause, then check the flag
- after the Try/Catch statement.
-
- IMPORTANT: The values of any non-volatile automatic variables
- changed within the Try clause are undefined after an exception is
- caught. Therefore, variables modified inside the Try block whose
- values are needed later outside the Try block must either use static
- storage or be declared with the "volatile" type qualifier.
-
-
-Throw expression;
-
- A Throw statement is very much like a return statement, except that
- the expression is required. Whereas return jumps back to the place
- where the current function was called, Throw jumps back to the Catch
- clause of the innermost enclosing Try clause. The expression must
- be compatible with the type passed to define_exception_type(). The
- exception must be caught, otherwise the program may crash.
-
- Slight limitation: If the expression is a comma-expression, it must
- be enclosed in parentheses.
-
-
-Try statement
-Catch_anonymous statement
-
- When the value of the exception is not needed, a Try/Catch statement
- can use Catch_anonymous instead of Catch (expression).
-
-
-Everything below this point is for the benefit of the compiler. The
-application programmer should pretend not to know any of it, because it
-is subject to change.

-cexcept: rationale 2.0.0 (2001-Jul-12-Thu)
-Adam M. Costello <amc@cs.berkeley.edu>
-
-Rationale for some of the design decisions behind version 2.0.* of the
-cexcept.h interface. See README for copyright information.
-
-
-Questions answered below:
- * Why aren't multiple Catch clauses allowed?
- * Why can't I say Catch (int e) like in C++ or Java?
- * Why can't I jump into or out of a Try clause?
- * Why isn't a Finally clause supported?
- * Why can't I use Throw without an expression to re-throw an exception?
- * Why can't "real" exceptions be caught?
- * Why must the Catch expression have the same type that was passed to
- define_exception_type()? I can assign a double value to an int, so
- why can't I catch a double exception in an int variable?
- * Why does the implementation copy the exception twice?
- * Why are the macros spelled Try, Catch, Throw rather than...?
-
-
-Why aren't multiple Catch clauses allowed?
-
- The purpose of multiple catch clauses in C++ or Java is to allow you
- to catch multiple exception types. This is natural in a language
- that supports polymorphism, where you can substitute objects of
- different types into the same expression and cause different code to
- be executed. In such a language you can throw any type of object,
- and the appropriate catch clause will be selected automatically.
-
- C does not support polymorphism (except for unions and void
- pointers). Therefore it is natural in C to have just one exception
- type, and therefore one Catch clause is sufficient. The application
- programmer is free to use any type for the exception type, and may
- use a union to simulate polymorphism (see example2.c for an example
- of this). But for many applications an int, enum, or small struct
- will be sufficient.
-
-
-But couldn't tricks be played to allow multiple exception types?
-
- Yes, but cexcept.h is intended for C programs and C programmers. If
- the concept of polymorphism were incorporated into the interface,
- the interface would become less intuitive to many of the people
- it is designed for. But if an application programmer uses unions
- to simulate multiple exception types, the resulting code will be
- perfectly understandable to other C programmers, even if they have
- no experience with polymorphism.
-
-
-Why can't I say Catch (int e) like in C++ or Java?
-
- Again, the interface tries to be intuitive to C programmers. In C,
- declarations go at the beginnings of blocks. The cexcept syntax is
- actually more flexible in a way, because any lvalue can go in the
- parentheses, for example: Catch (p->e)
-
-
-Why can't I jump into or out of a Try clause?
-
- There is some hidden setup and cleanup that needs to be done
- regardless of whether an exception is caught. Jumping into a Try
- clause would avoid doing the setup, and jumping out of it would
- avoid doing the cleanup.
-
-
-Why isn't a Finally clause supported?
-
- There's no way to implement it. In Java, the main difference
- between putting code in a finally clause versus putting the code
- after the try/catch statement is that the finally clause will get
- executed even if a return or throw occurs within the try clause or
- catch clause. But in C, a return statement returns immediately.
-
- In Java one could make do without a finally clause by deferring
- any return from the try clause (by storing the return value in a
- variable), and moving some or all of the catch code outside the
- try/catch statement, like so:
-
- Exception e = null;
-
- try { ... }
- catch (Exception tmp) { e = tmp; }
-
- // Do cleanup here.
-
- if (e instanceof Foo) { ... }
- else if (e instanceof Bar) { ... }
- ...
- else if (e != null) throw e;
-
- A similar technique can be used with cexcept:
-
- my_exception_type e = some null value that will not be thrown;
-
- Try { ... }
- Catch (e) { }
-
- /* Do cleanup here. */
-
- if (e is not that null value) { ... }
-
-
-Why can't I use Throw without an expression to re-throw an exception?
-
- The use of throw without an expression is needed in C++ because it's
- the only way to re-throw an exception of unknown type:
-
- catch (...) {
- // do some stuff
- throw;
- }
-
- This syntax is not provided in Java because the fact that all
- exceptions are instances of Exception eliminates the problem:
-
- catch (Exception e) {
- // do some stuff
- throw e;
- }
-
- Similarly, with cexcept, the type of exceptions is always known, so
- an expressionless Throw is not needed. Besides, the syntax would be
- very difficult, if not impossible, to implement.
-
-
-Why can't "real" exceptions be caught?
-
- "Real" exceptions (like floating-point exceptions and
- addressing exceptions) are platform-dependent, but cexcept is a
- platform-independent abstraction of setjmp/longjmp. The only way
- to jump to a setjmp() is from a longjmp(), so a Catch requires an
- explicit Throw.
-
- On POSIX systems, it is possible to call setjmp() from within a
- signal handler, and hence possible to use Throw within a signal
- handler, but this is very likely to cause subtle bugs and is not
- recommended. If a program uses both signals and cexcept, it may
- wish to modify cexcept.h to use the POSIX functions sigsetjmp() and
- siglongjmp() instead of the standard C library functions setjmp()
- and longjmp().
-
-
-Why must the Catch expression have the same type that was passed to
-define_exception_type()? I can assign a double value to an int, so why
-can't I catch a double exception in an int variable?
-
- The intuitive expectation is that "Throw v" and "Catch (e)" should
- have an effect equivalent to "e = v". The latter converts v to the
- type of e, but the Throw statement has no way of knowing the type of
- e, so it converts v to the type passed to define_exception_type().
- Depending on how cexcept is implemented, unintuitive or even
- undefined behavior could result if e has a different type.
-
-
-Why does the implementation copy the exception twice?
-
- The Throw statement must store the exception value somewhere. If it
- stores directly into the object named by the Catch expression, then
- that object must not be a non-volatile automatic object. It was
- deemed preferable to copy the exception twice rather than prohibit
- application programmers from catching exceptions in non-volatile
- automatic objects (which is what they would most often be inclined
- to use).
-
-
-Why are the macros spelled Try, Catch, Throw rather than...?
-
- We considered many other possibilities:
-
- try catch throw
- TRY CATCH THROW
- ctry ccatch cthrow
- c_try c_catch c_throw
- cex_try cex_catch cex_throw
- CEX_TRY CEX_CATCH CEX_THROW
- cexcept_try cexcept_catch cexcept_throw
- try_until_exception catch_exception throw_exception
-
- We wanted names that would be easy to read, easy to type, intuitive,
- and unlikely to conflict with existing names. Ultimately we settled
- on Try, Catch, and Throw as the best compromise among all these
- criteria.

-version 0.81 [August, 1995]
- incorporated Tim Wegner's medium model code (thanks, Tim)
-
-version 0.82 [September, 1995]
- [unspecified changes]
-
-version 0.85 [December, 1995]
- added more medium model code (almost everything's a far)
- added i/o, error, and memory callback functions
- fixed some bugs (16 bit, 4 bit interlaced, etc.)
- added first run progressive reader (barely tested)
-
-version 0.86 [January, 1996]
- fixed bugs
- improved documentation
-
-version 0.87 [January, 1996]
- fixed medium model bugs
- fixed other bugs introduced in 0.85 and 0.86
- added some minor documentation
-
-version 0.88 [January, 1996]
- fixed progressive bugs
- replaced tabs with spaces
- cleaned up documentation
- added callbacks for read/write and warning/error functions
-
-version 0.89 [July, 1996]
- added new initialization API to make libpng work better with shared libs
- we now have png_create_read_struct(), png_create_write_struct(),
- png_create_info_struct(), png_destroy_read_struct(), and
- png_destroy_write_struct() instead of the separate calls to
- malloc and png_read_init(), png_info_init(), and png_write_init()
- changed warning/error callback functions to fix bug - this means you
- should use the new initialization API if you were using the old
- png_set_message_fn() calls, and that the old API no longer exists
- so that people are aware that they need to change their code
- changed filter selection API to allow selection of multiple filters
- since it didn't work in previous versions of libpng anyways
- optimized filter selection code
- fixed png_set_background() to allow using an arbitrary RGB color for
- paletted images
- fixed gamma and background correction for paletted images, so
- png_correct_palette is not needed unless you are correcting an
- external palette (you will need to #define PNG_CORRECT_PALETTE_SUPPORTED
- in pngconf.h) - if nobody uses this, it may disappear in the future.
- fixed bug with Borland 64K memory allocation (Alexander Lehmann)
- fixed bug in interlace handling (Smarasderagd, I think)
- added more error checking for writing and image to reduce invalid files
- separated read and write functions so that they won't both be linked
- into a binary when only reading or writing functionality is used
- new pngtest image also has interlacing and zTXt
- updated documentation to reflect new API
-
-version 0.90 [January, 1997]
- made CRC errors/warnings on critical and ancillary chunks configurable
- libpng will use the zlib CRC routines by (compile-time) default
- changed DOS small/medium model memory support - needs zlib 1.04 (Tim Wegner)
- added external C++ wrapper statements to png.h (Gilles Dauphin)
- allow PNG file to be read when some or all of file signature has already
- been read from the beginning of the stream. ****This affects the size
- of info_struct and invalidates all programs that use a shared libpng****
- fixed png_filler() declarations
- fixed? background color conversions
- fixed order of error function pointers to match documentation
- current chunk name is now available in png_struct to reduce the number
- of nearly identical error messages (will simplify multi-lingual
- support when available)
- try to get ready for unknown-chunk callback functions:
- - previously read critical chunks are flagged, so the chunk handling
- routines can determine if the chunk is in the right place
- - all chunk handling routines have the same prototypes, so we will
- be able to handle all chunks via a callback mechanism
- try to fix Linux "setjmp" buffer size problems
- removed png_large_malloc, png_large_free, and png_realloc functions.
-
-version 0.95 [March, 1997]
- fixed bug in pngwutil.c allocating "up_row" twice and "avg_row" never
- fixed bug in PNG file signature compares when start != 0
- changed parameter type of png_set_filler(...filler...) from png_byte
- to png_uint_32
- added test for MACOS to ensure that both math.h and fp.h are not #included
- added macros for libpng to be compiled as a Windows DLL (Andreas Kupries)
- added "packswap" transformation, which changes the endianness of
- packed-pixel bytes (Kevin Bracey)
- added "strip_alpha" transformation, which removes the alpha channel of
- input images without using it (not necessarily a good idea)
- added "swap_alpha" transformation, which puts the alpha channel in front
- of the color bytes instead of after
- removed all implicit variable tests which assume NULL == 0 (I think)
- changed several variables to "png_size_t" to show 16/32-bit limitations
- added new pCAL chunk read/write support
- added experimental filter selection weighting (Greg Roelofs)
- removed old png_set_rgbx() and png_set_xrgb() functions that have been
- obsolete for about 2 years now (use png_set_filler() instead)
- added macros to read 16- and 32-bit ints directly from buffer, to be
- used only on those systems that support it (namely PowerPC and 680x0)
- With some testing, this may become the default for MACOS/PPC systems.
- only calculate CRC on data if we are going to use it
- added macros for zTXt compression type PNG_zTXt_COMPRESSION_???
- added macros for simple libpng debugging output selectable at compile time
- removed PNG_READ_END_MODE in progressive reader (Smarasderagd)
- more description of info_struct in libpng.txt and png.h
- more instructions in example.c
- more chunk types tested in pngtest.c
- renamed pngrcb.c to pngset.c, and all png_read_<chunk> functions to be
- png_set_<chunk>. We now have corresponding png_get_<chunk>
- functions in pngget.c to get information in info_ptr. This isolates
- the application from the internal organization of png_info_struct
- (good for shared library implementations).

- png_get_spalettes, png_set_iCCP, png_set_spalettes (Eric S. Raymond).
- NOTE: Applications that write text chunks MUST define png_text->lang
- before calling png_set_text(). It must be set to NULL if you want to
- write tEXt or zTXt chunks. If you want your application to be able to
- run with older versions of libpng, use
-
- #ifdef PNG_iTXt_SUPPORTED
- png_text[i].lang = NULL;
- #endif
-
- Changed png_get_oFFs() and png_set_oFFs() to use signed rather than unsigned

- Restored the first four members of png_text to the same order as v.1.0.5d.
- Added members "lang_key" and "itxt_length" to png_text struct. Set
- text_length=0 when "text" contains iTXt data. Use the "compression"
- member to distinguish among tEXt/zTXt/iTXt types. Added
- PNG_ITXT_COMPRESSION_NONE (1) and PNG_ITXT_COMPRESSION_zTXt(2) macros.
- The "Note" above, about backward incompatibility of libpng-1.0.5e, no
- longer applies.

-version 1.0.5n [January 9, 2000]
- Added png_free_PLTE() function, and modified png_set_PLTE() to malloc its
- own memory for info_ptr->palette. This makes it safe for the calling

-version 1.0.5o [January 20, 2000]
- Cosmetic changes only (removed some trailing blanks and TABs)

- example.c, pngtest.c, and contrib programs to use this macro.
- Revised some of the DLL-export macros in pngconf.h (Greg Roelofs)
- Fixed a bug in png_read_png() that caused it to fail to expand some images
- that it should have expanded.
- Fixed some mistakes in the unused and undocumented INCH_CONVERSIONS functions
- in pngget.c

- (breaks compatibility with libpng-1.0.6).
-version 1.0.6h [April 24, 2000]
- Changed shared library so-number pattern from 2.x.y.z to xy.z (this builds
- libpng.so.10 & libpng.so.10.6h instead of libpng.so.2 & libpng.so.2.1.0.6h)
- This is a temporary change for test purposes.
-version 1.0.6i [May 2, 2000]
- Rearranged some members at the end of png_info and png_struct, to put
- unknown_chunks_num and free_me within the original size of the png_structs
- and free_me, png_read_user_fn, and png_free_fn within the original png_info,
- because some old applications allocate the structs directly instead of
- using png_create_*().
- Added documentation of user memory functions in libpng.txt/libpng.3
- Modified png_read_png so that it will use user_allocated row_pointers
- if present, unless free_me directs that it be freed, and added description

- (new in version 1.0.2), rgb_to_gray (new in 1.0.5), iCCP, sCAL, sPLT,
- the high-level interface, and unknown chunks support (all new in 1.0.6).
- This was necessary because of old applications that allocate the structs
- directly as authors were instructed to do in libpng-0.88 and earlier,
- instead of using png_create_*().
- Added modes PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT which
- can be used to detect codes that directly allocate the structs, and
- code to check these modes in png_read_init() and png_write_init() and
- generate a libpng error if the modes aren't set and PNG_LEGACY_SUPPORTED
- was not defined.
- Added makefile.intel and updated makefile.watcom (Pawel Mrochen)
-version 1.0.6j [May 3, 2000]

- Removed the new PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT modes
- which are no longer used.
- Eliminated the three new members of png_text when PNG_LEGACY_SUPPORTED is
- defined or when neither PNG_READ_iTXt_SUPPORTED nor PNG_WRITE_iTXT_SUPPORTED
- is defined.
- Made PNG_NO_READ|WRITE_iTXt the default setting, to avoid memory
- overrun when old applications fill the info_ptr->text structure directly.
- Added PNGAPI macro, and added it to the definitions of all exported functions.
- Relocated version macro definitions ahead of the includes of zlib.h and
- pngconf.h in png.h.
-version 1.0.7beta12 [May 12, 2000]

- Added png_access_version_number() function.
- Check for mask&PNG_FREE_CHNK (for TEXT, SCAL, PCAL) in png_free_data().

-version 1.0.7beta14 [May 17, 2000] (beta13 was not published)
- Changed pnggccrd.c and pngvcrd.c to handle bad adaptive filter types as
- warnings instead of errors, as pngrutil.c does.
- Set the PNG_INFO_IDAT valid flag in png_set_rows() so png_write_png()
- will actually write IDATs.
- Made the default PNG_USE_LOCAL_ARRAYS depend on PNG_DLL instead of WIN32.
- Make png_free_data() ignore its final parameter except when freeing data
- that can have multiple instances (text, sPLT, unknowns).
- Fixed a new bug in png_set_rows().
- Removed info_ptr->valid tests from png_free_data(), as in version 1.0.5.
- Added png_set_invalid() function.
- Fixed incorrect illustrations of png_destroy_write_struct() in example.c.

- fewer error messages.
- Rearranged checks for Z_OK to check the most likely path first in pngpread.c
- and pngwutil.c.
- Added checks in pngtest.c for png_create_*() returning NULL, and mentioned
- in libpng.txt/libpng.3 the need for applications to check this.
- Changed names of png_default_*() functions in pngtest to pngtest_*().
- Changed return type of png_get_x|y_offset_*() from png_uint_32 to png_int_32.
- Fixed some bugs in the unused PNG_INCH_CONVERSIONS functions in pngget.c
- Set each pointer to NULL after freeing it in png_free_data().
- Worked around a problem in pngconf.h; AIX's strings.h defines an "index"
- macro that conflicts with libpng's png_color_16.index. (Dimitri Papadapoulos)
- Added "msvc" directory with MSVC++ project files (Simon-Pierre Cadieux).
-version 1.0.7beta16 [June 4, 2000]
- Revised the workaround of AIX string.h "index" bug.
- Added a check for overlength PLTE chunk in pngrutil.c.
- Added PNG_NO_POINTER_INDEXING macro to use array-indexing instead of pointer
- indexing in pngrutil.c and pngwutil.c to accommodate a buggy compiler.

- Rebuilt configure scripts with autoconf-2.68 instead of autoconf-2.65
-
-version 1.4.5beta02 [October 5, 2010]
- Reverted configure scripts to autoconf-2.65
- Fixed problem with symbols creation in Makefile.am which was assuming that
- all versions of cpp write to standard output by default (Martin Banky). The
- bug was introduced in libpng-1.2.9beta5.
-
-version 1.4.5beta03 [October 8, 2010]
- Wrapped long lines in CMakeLists.txt and introduced ${libpng_public_hdrs}
- Undid Makefile.am revision of 1.4.5beta02.
-
-version 1.4.5beta04 [November 8, 2010]
- Check for out-of-range text compression mode in png_set_text().
-
-version 1.4.5rc01 [November 19, 2010]
- No changes.
-
-version 1.4.5beta05 [November 20, 2010]
- Revised png_get_uint_32, png_get_int_32, png_get_uint_16 (Cosmin)
- Moved reading of file signature into png_read_sig (Cosmin)
- Fixed atomicity of chunk header serialization (Cosmin)
- Added test for io_state in pngtest.c (Cosmin)
- Added "#!/bin/sh" at the top of contrib/pngminim/*/gather.sh scripts.
-
-version 1.4.5beta06 [November 21, 2010]
- Restored the parentheses in pngrutil.c; they are needed when the
- png_get_*int_*() functions are compiled (i.e., when PNG_USE_READ_MACROS
- is not defined).
- Make the "png_get_uint_16" macro return a png_uint_32 in libpng-1.4 for API
- compatibility.
- Changes to remove gcc warnings (John Bowler)
- Certain optional gcc warning flags resulted in warnings in libpng code.
- With these changes only -Wconversion and -Wcast-qual cannot be turned on.
- Changes are trivial rearrangements of code. -Wconversion is not possible
- for pngrutil.c (because of the widespread use of += et al on variables
- smaller than (int) or (unsigned int)) and -Wcast-qual is not possible
- with pngwio.c and pngwutil.c because the 'write' callback and zlib
- compression both fail to declare their input buffers with 'const'.
-
-version 1.4.5beta07 [November 25, 2010]
- Reverted png_get_uint_16 macro to beta05 and added comment about the
- potential API incompatibility.
-
-version 1.4.5rc02 [December 2, 2010]
- No changes.
-

- Added missing vstudio/*/*.vcxproj files to the zip and 7z distributions.
-
-version 1.4.5 [December 9, 2010]
- Removed PNG_NO_WRITE_GAMMA from pngminim/encoder/pngusr.h
-
-version 1.4.6beta01 [December 29, 2010]
- Fixed bug in background transformation handling in pngrtran.c (it was
- looking for the flag in png_ptr->transformations instead of in
- png_ptr->flags) (David Raymond).
-
-version 1.4.6beta02 [January 14, 2011]
- Fixed misspelled macros in contrib/pngminim (Cosmin).
- Updated CMakeLists.txt (Clifford Yapp).
-
-version 1.4.6beta03 [January 14, 2011]
- Fixed some typecasts in png_debug statements (Cosmin).
-
-version 1.4.6beta04 [January 22, 2011]
- Updated documentation of png_set|get_tRNS() (Thomas Klausner).
- Added png_const_structp and png_const_infop types, and used them in
- prototypes for most png_get_*() functions.
- In the manual, describe the png_get_IHDR() arguments in the correct order.
- Ported change in png_do_rgb_to_gray() from libpng-1.5.1, to make
- it more robust against internal libpng coding errors.
-
-version 1.4.6beta05 [January 23, 2011]
-
- Updated the synopses in the manual to reflect recent changes.
- Fixed a typo in the *.def files and deleted entries that are now
- declared in pngpriv.h
-
-version 1.4.6beta06 [March 19, 2011]
- Updated contrib/pngsuite/README to add the word "modify".
- Added the private PNG_UNUSED() macro definition in pngconf.h.
-
-version 1.4.6beta07 [March 22, 2011]
- ifdef out mask arrays in pngread.c when interlacing is not supported.
- Added attribute definition (warnings) for MSC_VER >= 1300 in pngconf.h
- Added -D_CRT_SECURE_NO_DEPRECATE to CFLAGS in makefile.vcwin32
- Fixed mistake in the descriptions of user read_transform and write_transform
- function prototypes in the manual. The row_info struct is png_row_infop.
- Added a request in the manual that applications do not use "png_" or
- "PNG_" to begin any of their own symbols.
- Fixed incorrect examples of callback prototypes in the manual, that were
- introduced in libpng-1.0.0.
- Removed "strip" from contrib/pngminim/*/makefile.
- Fixed a bug (present since libpng-1.0.7) that makes png_handle_sPLT() fail
- to compile when PNG_NO_POINTER_INDEXING is defined (Chubanov Kirill)
-
-version 1.4.6rc01 [March 31, 2011]
- No changes.
-
-version 1.4.6rc02 [April 6, 2011]
- Improved the optimization of the zlib CMF byte (see libpng-1.2.6beta03).

- Relocated misplaced new declarations in pngwutil.c.
-
-version 1.4.7 [April 9, 2011]
- Disabled PNG_PEDANTIC_WARNINGS for all MSC versions as in libpng-1.4.5.
-
-version 1.4.8beta01 [June 4, 2011]
- Undef "_ALL_SOURCE" for AIX, to prevent "jmpbuf" from being redefined.
- Copied png_debug macros from pngpriv.h into pngtest.c and removed
- "#include pngpriv.h" from pngtest.c, to avoid setting a bad example.
- Pass "" instead of '\0' to png_default_error() in png_err(). This mistake
- was introduced in libpng-1.2.20beta01.
- Check for up->location !PNG_AFTER_IDAT when writing unknown chunks
- before IDAT.
- Ported bugfix in pngrtran.c from 1.5.3: when expanding a paletted image,
- always expand to RGBA if transparency is present.
-
-version 1.4.8beta02 [June 5, 2011]
- Ported bugfix in pngrtran.c from 1.5.3: Ensure coefficients are OK for
- png_rgb_to_gray_fixed().
-
-version 1.4.8beta03 [June 6, 2011]
- Check for integer overflow in png_set_rgb_to_gray().
-
-version 1.4.8beta04 [June 7, 2011]

- Updated contrib/pngminus/makefile.std (Samuli Souminen)
- Added SunOS support to configure.ac and Makefile.am (but configure and
- Makefile.in were not updated)
-
-version 1.4.9rc01 [February 17, 2012]
- Fixed CVE-2011-3026 buffer overrun bug. This bug was introduced when
- iCCP chunk support was added at libpng-1.0.6. Deal more correctly with the
- test on iCCP chunk length. Also removed spurious casts that may hide
- problems on 16-bit systems.
-
-version 1.4.9 [February 18, 2012]
- No changes.
-
-version 1.4.10beta01 [February 27, 2011]
- Removed two useless #ifdef directives from pngread.c and one from pngrutil.c
- Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from
- pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c;
- now that png_ptr->buffer is inaccessible to applications, the special
- handling is no longer useful.

- Fixed incorrect type (int copy should be png_size_t copy) in png_inflate()
- (fixes CVE-2011-3045).
- Fixed off-by-one bug in png_handle_sCAL() when using fixed point arithmetic,
- causing out-of-bounds read in png_set_sCAL() because of failure to copy
- the string terminators. This bug was introduced in libpng-1.0.6 (Frank
- Busse).
-
-version 1.4.10rc01 [March 2, 2012]
- Removed the png_free() of unused png_ptr->current_text from pngread.c.

- Revised png_set_text_2() to avoid potential memory corruption (fixes
- CVE-2011-3048).
- Prevent PNG_EXPAND+PNG_SHIFT doing the shift twice.
-
-version 1.4.12 [July 10, 2012]
- Added two images to contrib/pngsuite (1-bit and 2-bit transparent grayscale),
- and renamed three whose names were inconsistent with those in
- pngsuite/README.txt.
- Changed "a+w" to "u+w" in Makefile.in to fix CVE-2012-3386.

- ./configure [--prefix=/path]
- make check
- make install
-
-and ignore the rest of this document.
-
-If configure does not work on your system and you have a reasonably
-up-to-date set of tools, running ./autogen.sh before running ./configure
-may fix the problem. You can also run the individual commands in
-autogen.sh with the --force option, if supported by your version of
-the tools. If you run 'libtoolize --force', though, this will replace
-the distributed, patched, version of ltmain.sh with an unpatched version
-and your shared library builds may fail to produce libraries with the
-correct version numbers.
-
-Instead, you can use one of the custom-built makefiles in the
-"scripts" directory
-
- cp scripts/makefile.system makefile
- make test
- make install
-
-The files that are presently available in the scripts directory
-are listed and described in scripts/README.txt.
-
-Or you can use one of the "projects" in the "projects" directory.
-
-Before installing libpng, you must first install zlib, if it
-is not already on your system. zlib can usually be found
-wherever you got libpng. zlib can be placed in another directory,
-at the same level as libpng.
-
-If you want to use "cmake" (see www.cmake.org), type
-
- cmake . -DCMAKE_INSTALL_PREFIX=/path
- make
- make install
-
-If your system already has a preinstalled zlib you will still need
-to have access to the zlib.h and zconf.h include files that
-correspond to the version of zlib that's installed.
-
-You can rename the directories that you downloaded (they
-might be called "libpng-1.4.12" or "libpng14" and "zlib-1.2.3"
-or "zlib123") so that you have directories called "zlib" and "libpng".
-
-Your directory structure should look like this:
-
- .. (the parent directory)
- libpng (this directory)
- INSTALL (this file)
- README
- *.h
- *.c
- CMakeLists.txt => "cmake" script
- configuration files:
- configure.ac, configure, Makefile.am, Makefile.in,
- autogen.sh, config.guess, ltmain.sh, missing,
- aclocal.m4, config.h.in, config.sub,
- depcomp, install-sh, test-pngtest.sh
- contrib
- gregbook
- pngminim
- pngminus
- pngsuite
- visupng
- projects
- cbuilder5 (Borland)
- visualc6 (msvc)
- visualc71
- vstudio
- xcode
- scripts
- makefile.*
- *.def (module definition files)
- pngtest.png
- etc.
- zlib
- README
- *.h
- *.c
- contrib
- etc.
-
-If the line endings in the files look funny, you may wish to get the other
-distribution of libpng. It is available in both tar.gz (UNIX style line
-endings) and zip (DOS style line endings) formats.
-
-If you are building libpng with MSVC, you can enter the
-libpng projects\visualc6 or visualc71 directory and follow the instructions
-in README.txt.
-
-Otherwise enter the zlib directory and follow the instructions in zlib/README,
-then come back here and run "configure" or choose the appropriate
-makefile.sys in the scripts directory.
-
-Copy the file (or files) that you need from the
-scripts directory into this directory, for example
-
- MSDOS example: copy scripts\makefile.msc makefile
- UNIX example: cp scripts/makefile.std makefile
-
-Read the makefile to see if you need to change any source or
-target directories to match your preferences.
-
-Then read pngconf.h to see if you want to make any configuration
-changes.
-
-Then just run "make" which will create the libpng library in
-this directory and "make test" which will run a quick test that reads
-the "pngtest.png" file and writes a "pngout.png" file that should be
-identical to it. Look for "9782 zero samples" in the output of the
-test. For more confidence, you can run another test by typing
-"pngtest pngnow.png" and looking for "289 zero samples" in the output.
-Also, you can run "pngtest -m contrib/pngsuite/*.png" and compare
-your output with the result shown in contrib/pngsuite/README.
-
-Most of the makefiles will allow you to run "make install" to
-put the library in its final resting place (if you want to
-do that, run "make install" in the zlib directory first if necessary).
-Some also allow you to run "make test-installed" after you have
-run "make install".
-
-If you encounter a compiler error message complaining about the
-lines
-
- __png.h__ already includes setjmp.h;
- __dont__ include it again.;
-
-this means you have compiled another module that includes setjmp.h,
-which is hazardous because the two modules might not include exactly
-the same setjmp.h. If you are sure that you know what you are doing
-and that they are exactly the same, then you can comment out or
-delete the two lines. Better yet, use the cexcept interface
-instead, as demonstrated in contrib/visupng of the libpng distribution.
-
-Further information can be found in the README and libpng.txt
-files, in the individual makefiles, in png.h, and the manual pages
-libpng.3 and png.5.

-README for libpng version 1.4.12 - July 10, 2012 (shared library 14.0)
-See the note about version numbers near the top of png.h
-
-See INSTALL for instructions on how to install libpng.
-
-Libpng comes in several distribution formats. Get libpng-*.tar.gz,
-libpng-*.tar.xz or libpng-*.tar.bz2 if you want UNIX-style line endings
-in the text files, or lpng*.zip if you want DOS-style line endings.
-
-Version 0.89 was the first official release of libpng. Don't let the
-fact that it's the first release fool you. The libpng library has been in
-extensive use and testing since mid-1995. By late 1997 it had
-finally gotten to the stage where there hadn't been significant
-changes to the API in some time, and people have a bad feeling about
-libraries with versions < 1.0. Version 1.0.0 was released in
-March 1998.
-
-****
-Note that some of the changes to the png_info structure render this
-version of the library binary incompatible with libpng-0.89 or
-earlier versions if you are using a shared library. The type of the
-"filler" parameter for png_set_filler() has changed from png_byte to
-png_uint_32, which will affect shared-library applications that use
-this function.
-
-To avoid problems with changes to the internals of png_info_struct,
-new APIs have been made available in 0.95 to avoid direct application
-access to info_ptr. These functions are the png_set_<chunk> and
-png_get_<chunk> functions. These functions should be used when
-accessing/storing the info_struct data, rather than manipulating it
-directly, to avoid such problems in the future.
-
-It is important to note that the APIs do not make current programs
-that access the info struct directly incompatible with the new
-library. However, it is strongly suggested that new programs use
-the new APIs (as shown in example.c and pngtest.c), and older programs
-be converted to the new format, to facilitate upgrades in the future.
-****
-
-Additions since 0.90 include the ability to compile libpng as a
-Windows DLL, and new APIs for accessing data in the info struct.
-Experimental functions include the ability to set weighting and cost
-factors for row filter selection, direct reads of integers from buffers
-on big-endian processors that support misaligned data access, faster
-methods of doing alpha composition, and more accurate 16->8 bit color
-conversion.
-
-The additions since 0.89 include the ability to read from a PNG stream
-which has had some (or all) of the signature bytes read by the calling
-application. This also allows the reading of embedded PNG streams that
-do not have the PNG file signature. As well, it is now possible to set
-the library action on the detection of chunk CRC errors. It is possible
-to set different actions based on whether the CRC error occurred in a
-critical or an ancillary chunk.
-
-The changes made to the library, and bugs fixed are based on discussions
-on the PNG-implement mailing list and not on material submitted
-privately to Guy, Andreas, or Glenn. They will forward any good
-suggestions to the list.
-
-For a detailed description on using libpng, read libpng.txt. For
-examples of libpng in a program, see example.c and pngtest.c. For usage
-information and restrictions (what little they are) on libpng, see
-png.h. For a description on using zlib (the compression library used by
-libpng) and zlib's restrictions, see zlib.h
-
-I have included a general makefile, as well as several machine and
-compiler specific ones, but you may have to modify one for your own needs.
-
-You should use zlib 1.0.4 or later to run this, but it MAY work with
-versions as old as zlib 0.95. Even so, there are bugs in older zlib
-versions which can cause the output of invalid compression streams for
-some images. You will definitely need zlib 1.0.4 or later if you are
-taking advantage of the MS-DOS "far" structure allocation for the small
-and medium memory models. You should also note that zlib is a
-compression library that is useful for more things than just PNG files.
-You can use zlib as a drop-in replacement for fread() and fwrite() if
-you are so inclined.
-
-zlib should be available at the same place that libpng is, or at.
-ftp://ftp.info-zip.org/pub/infozip/zlib
-
-You may also want a copy of the PNG specification. It is available
-as an RFC, a W3C Recommendation, and an ISO/IEC Standard. You can find
-these at http://www.libpng.org/pub/png/documents/
-
-This code is currently being archived at libpng.sf.net in the
-[DOWNLOAD] area, and on CompuServe, Lib 20 (PNG SUPPORT)
-at GO GRAPHSUP. If you can't find it in any of those places,
-e-mail me, and I'll help you find it.
-
-If you have any code changes, requests, problems, etc., please e-mail
-them to me. Also, I'd appreciate any make files or project files,
-and any modifications you needed to make to get libpng to compile,
-along with a #define variable to tell what compiler/system you are on.
-If you needed to add transformations to libpng, or wish libpng would
-provide the image in a different way, drop me a note (and code, if
-possible), so I can consider supporting the transformation.
-Finally, if you get any warning messages when compiling libpng
-(note: not zlib), and they are easy to fix, I'd appreciate the
-fix. Please mention "libpng" somewhere in the subject line. Thanks.
-
-This release was created and will be supported by myself (of course
-based in a large way on Guy's and Andreas' earlier work), and the PNG
-development group.

-
-You can't reach Guy, the original libpng author, at the addresses
-given in previous versions of this document. He and Andreas will
-read mail addressed to the png-implement list, however.
-
-Please do not send general questions about PNG. Send them to
-png-mng-misc at lists.sf.net (subscription required; visit
-https://lists.sourceforge.net/lists/listinfo/png-mng-misc to
-subscribe). If you have a question about something
-in the PNG specification that is related to using libpng, send it
-to me. Send me any questions that start with "I was using libpng,
-and ...". If in doubt, send questions to me. I'll bounce them
-to others, if necessary.
-
-Please do not send suggestions on how to change PNG. We have
-been discussing PNG for sixteen years now, and it is official and
-finished. If you have suggestions for libpng, however, I'll
-gladly listen. Even if your suggestion is not used immediately,
-it may be used later.

-/*
-TODO - list of things to do for libpng:
-
-Final bug fixes.
-Improve API by hiding the png_struct and png_info structs.
-Finish work on the no-floating-point version (including gamma compensation)
-Better C++ wrapper/full C++ implementation?
-Fix problem with C++ and EXTERN "C".
-cHRM transformation.
-Improve setjmp/longjmp usage or remove it in favor of returning error codes.
-Add "grayscale->palette" transformation and "palette->grayscale" detection.
-Improved quantizing and dithering.
-Multi-lingual error and warning message support.
-Complete sRGB transformation (presently it simply uses gamma=0.45455).
-Man pages for function calls.
-Better documentation.
-Better filter selection
- (counting huffman bits/precompression? filter inertia? filter costs?).
-Histogram creation.
-Text conversion between different code pages (Latin-1 -> Mac and DOS).
-Build gamma tables using fixed point (and do away with floating point entirely).
-Avoid building gamma tables whenever possible.
-Use greater precision when changing to linear gamma for compositing against
- background and doing rgb-to-gray transformation.
-Investigate pre-incremented loop counters and other loop constructions.
-Add interpolated method of handling interlacing.
-Provide for conditional compilation of 16-bit support (except for the
- initial stripping down to 8-bits when reading a 16-bit PNG datastream).
-Switch to the simpler zlib (zlib/libpng) license if legally possible.

-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)

-# So we provide this file, which has a silly filename so it's always
-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-\`configure' configures libpng 1.4.12 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]
- --includedir=DIR C header files [PREFIX/include]
- --oldincludedir=DIR C header files for non-gcc [/usr/include]
- --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
- --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
- --infodir=DIR info documentation [DATAROOTDIR/info]
- --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
- --mandir=DIR man documentation [DATAROOTDIR/man]

- --disable-option-checking ignore unrecognized --enable/--with options
- --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
- --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
- --enable-maintainer-mode enable make rules and dependencies not useful
- (and sometimes confusing) to the casual installer
- --disable-dependency-tracking speeds up one-time build
- --enable-dependency-tracking do not reject slow dependency extractors
- --enable-shared[=PKGS] build shared libraries [default=yes]
- --enable-static[=PKGS] build static libraries [default=yes]
- --enable-fast-install[=PKGS]
- optimize for fast installation [default=yes]
- --disable-libtool-lock avoid locking (might break parallel builds)
-
-Optional Packages:
- --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
- --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
- --with-gnu-ld assume the C compiler uses GNU ld [default=no]
- --with-pic try to use only PIC/non-PIC objects [default=use
- both]
- --with-pkgconfigdir Use the specified pkgconfig dir (default is
- libdir/pkgconfig)
- --with-binconfigs Generate shell libpng-config scripts as well as
- pkg-config data [default=yes]
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CPP C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to <png-mng-implement@lists.sourceforge.net>.

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>

- PNG: The Definitive Guide
- ===========================
-
- Source Code
-
-Chapters 13, 14 and 15 of "PNG: The Definitive Guide" discuss three free,
-cross-platform demo programs that show how to use the libpng reference
-library: rpng, rpng2 and wpng. rpng and rpng2 are viewers; the first is
-a very simple example that that shows how a standard file-viewer might use
-libpng, while the second is designed to process streaming data and shows
-how a web browser might be written. wpng is a simple command-line program
-that reads binary PGM and PPM files (the ``raw'' grayscale and RGB subsets
-of PBMPLUS/NetPBM) and converts them to PNG.
-
-The source code for all three demo programs currently compiles under
-Unix, OpenVMS, and 32-bit Windows. (Special thanks to Martin Zinser,
-zinser@decus.de, for making the necessary changes for OpenVMS and for
-providing an appropriate build script.) Build instructions can be found
-below.

-
-Note that, although the programs are designed to be functional, their
-primary purpose is to illustrate how to use libpng to add PNG support to
-other programs. As such, their user interfaces are crude and definitely
-are not intended for everyday use.
-
-Please see http://www.libpng.org/pub/png/pngbook.html for further infor-
-mation and links to the latest version of the source code, and Chapters
-13-15 of the book for detailed discussion of the three programs.

-BUILD INSTRUCTIONS
-
- - Prerequisites (in order of compilation):
-
- - zlib http://zlib.net/
- - libpng http://www.libpng.org/pub/png/libpng.html
- - pngbook http://www.libpng.org/pub/png/book/sources.html
-
- The pngbook demo programs are explicitly designed to demonstrate proper
- coding techniques for using the libpng reference library. As a result,
- you need to download and build both zlib (on which libpng depends) and
- libpng. A common build setup is to place the zlib, libpng and pngbook
- subdirectory trees ("folders") in the same parent directory. Then the
- libpng build can refer to files in ../zlib (or ..\zlib or [-.zlib]),
- and similarly for the pngbook build.
-
- Note that all three packages are designed to be built from a command
- line by default; those who wish to use a graphical or other integrated
- development environments are on their own.
-
-
- - Unix:
-
- Unpack the latest pngbook sources (which should correspond to this
- README file) into a directory and change into that directory.
-
- Copy Makefile.unx to Makefile and edit the PNG* and Z* variables
- appropriately (possibly also the X* variables if necessary).
-
- make
-
- There is no "install" target, so copy the three executables somewhere
- in your path or run them from the current directory. All three will
- print a basic usage screen when run without any command-line arguments;
- see the book for more details.
-
-
- - Windows:
-
- Unpack the latest pngbook sources (which should correspond to this
- README file) into a folder, open a "DOS shell" or "command prompt"
- or equivalent command-line window, and cd into the folder where you
- unpacked the source code.
-
- For MSVC, set up the necessary environment variables by invoking
-
- %devstudio%\vc\bin\vcvars32.bat
-
- where where %devstudio% is the installation directory for MSVC /
- DevStudio. If you get "environment out of space" errors under 95/98,
- create a desktop shortcut with "c:\windows\command.com /e:4096" as
- the program command line and set the working directory to the pngbook
- directory. Then double-click to open the new DOS-prompt window with
- a bigger environment and retry the commands above.
-
- Copy Makefile.w32 to Makefile and edit the PNGPATH and ZPATH variables
- appropriately (possibly also the "INC" and "LIB" variables if needed).
- Note that the names of the dynamic and static libpng and zlib libraries
- used in the makefile may change in later releases of the libraries.
- Also note that, as of libpng version 1.0.5, MSVC DLL builds do not work.
- This makefile therefore builds statically linked executables, but if
- the DLL problems ever get fixed, uncommenting the appropriate PNGLIB
- and ZLIB lines will build dynamically linked executables instead.
-
- Do the build by typing
-
- nmake
-
- The result should be three executables: rpng-win.exe, rpng2-win.exe,
- and wpng.exe. Copy them somewhere in your PATH or run them from the
- current folder. Like the Unix versions, the two windowed programs
- (rpng and rpng2) now display a usage screen in a console window when
- invoked without command-line arguments; this is new behavior as of
- the June 2001 release. Note that the programs use the Unix-style "-"
- character to specify options, instead of the more common DOS/Windows
- "/" character. (For example: "rpng2-win -bgpat 4 foo.png", not
- "rpng2-win /bgpat 4 foo.png")
-
-
- - OpenVMS:
-
- Unpack the pngbook sources into a subdirectory and change into that
- subdirectory.
-
- Edit makevms.com appropriately, specifically the zpath and pngpath
- variables.
-
- @makevms
-
- To run the programs, they probably first need to be set up as "foreign
- symbols," with "disk" and "dir" set appropriately:
-
- $ rpng == "$disk:[dir]rpng-x.exe"
- $ rpng2 == "$disk:[dir]rpng2-x.exe"
- $ wpng == "$disk:[dir]wpng.exe"
-
- All three will print a basic usage screen when run without any command-
- line arguments; see the book for more details. Note that the options
- style is Unix-like, i.e., preceded by "-" rather than "/".
-
-
-RUNNING THE PROGRAMS: (VERY) BRIEF INTRO
-
- rpng is a simple PNG viewer that can display transparent PNGs with a
- specified background color; for example,
-
- rpng -bgcolor \#ff0000 toucan.png
-
- would display the image with a red background. rpng2 is a progressive
- viewer that simulates a web browser in some respects; it can display
- images against either a background color or a dynamically generated
- background image. For example:
-
- rpng2 -bgpat 16 toucan.png
-
- wpng is a purely command-line image converter from binary PBMPLUS/NetPBM
- format (.pgm or .ppm) to PNG; for example,
-
- wpng -time < toucan-notrans.ppm > toucan-notrans.png
-
- would convert the specified PPM file (using redirection) to PNG, auto-
- matically setting the PNG modification-time chunk.
-
- All options can be abbreviated to the shortest unique value; for example,
- "-bgc" for -bgcolor (versus "-bgp" for -bgpat), or "-g" for -gamma.

- rpng - simple PNG display program rpng-win.c
-
- This program decodes and displays PNG images, with gamma correction and
- optionally with a user-specified background color (in case the image has
- transparency). It is very nearly the most basic PNG viewer possible.
- This version is for 32-bit Windows; it may compile under 16-bit Windows
- with a little tweaking (or maybe not).
-
- to do:
- - handle quoted command-line args (especially filenames with spaces)
- - have minimum window width: oh well
- - use %.1023s to simplify truncation of title-bar string?
-
- ---------------------------------------------------------------------------
-
- Changelog:
- - 1.00: initial public release
- - 1.01: modified to allow abbreviated options; fixed long/ulong mis-
- match; switched to png_jmpbuf() macro
- - 1.02: added extra set of parentheses to png_jmpbuf() macro; fixed
- command-line parsing bug
- - 1.10: enabled "message window"/console (thanks to David Geldreich)
- - 2.00: dual-licensed (added GNU GPL)
- - 2.01: fixed improper display of usage screen on PNG error(s)

- rpng - simple PNG display program rpng-x.c
-
- This program decodes and displays PNG images, with gamma correction and
- optionally with a user-specified background color (in case the image has
- transparency). It is very nearly the most basic PNG viewer possible.
- This version is for the X Window System (tested by author under Unix and
- by Martin Zinser under OpenVMS; may work under OS/2 with some tweaking).
-
- to do:
- - 8-bit (colormapped) X support
- - use %.1023s to simplify truncation of title-bar string?
-
- ---------------------------------------------------------------------------
-
- Changelog:
- - 1.01: initial public release
- - 1.02: modified to allow abbreviated options; fixed long/ulong mis-
- match; switched to png_jmpbuf() macro
- - 1.10: added support for non-default visuals; fixed X pixel-conversion
- - 1.11: added extra set of parentheses to png_jmpbuf() macro; fixed
- command-line parsing bug
- - 1.12: fixed some small X memory leaks (thanks to François Petitjean)
- - 1.13: fixed XFreeGC() crash bug (thanks to Patrick Welche)
- - 1.14: added support for X resources (thanks to Gerhard Niklasch)
- - 2.00: dual-licensed (added GNU GPL)
- - 2.01: fixed improper display of usage screen on PNG error(s)

- rpng2 - progressive-model PNG display program rpng2-win.c
-
- This program decodes and displays PNG files progressively, as if it were
- a web browser (though the front end is only set up to read from files).
- It supports gamma correction, user-specified background colors, and user-
- specified background patterns (for transparent images). This version is
- for 32-bit Windows; it may compile under 16-bit Windows with a little
- tweaking (or maybe not). Thanks to Adam Costello and Pieter S. van der
- Meulen for the "diamond" and "radial waves" patterns, respectively.
-
- to do (someday, maybe):
- - handle quoted command-line args (especially filenames with spaces)
- - finish resizable checkerboard-gradient (sizes 4-128?)
- - use %.1023s to simplify truncation of title-bar string?
- - have minimum window width: oh well
-
- ---------------------------------------------------------------------------
-
- Changelog:
- - 1.01: initial public release
- - 1.02: fixed cut-and-paste error in usage screen (oops...)
- - 1.03: modified to allow abbreviated options
- - 1.04: removed bogus extra argument from usage fprintf() [Glenn R-P?];
- fixed command-line parsing bug
- - 1.10: enabled "message window"/console (thanks to David Geldreich)
- - 1.20: added runtime MMX-enabling/disabling and new -mmx* options
- - 1.21: made minor tweak to usage screen to fit within 25-line console
- - 1.22: added AMD64/EM64T support (__x86_64__)
- - 2.00: dual-licensed (added GNU GPL)
- - 2.01: fixed 64-bit typo in readpng2.c
- - 2.02: fixed improper display of usage screen on PNG error(s); fixed
- unexpected-EOF and file-read-error cases
- - 2.03: removed runtime MMX-enabling/disabling and obsolete -mmx* options

- rpng2 - progressive-model PNG display program rpng2-x.c
-
- This program decodes and displays PNG files progressively, as if it were
- a web browser (though the front end is only set up to read from files).
- It supports gamma correction, user-specified background colors, and user-
- specified background patterns (for transparent images). This version is
- for the X Window System (tested by the author under Unix and by Martin
- Zinser under OpenVMS; may work under OS/2 with a little tweaking).
-
- Thanks to Adam Costello and Pieter S. van der Meulen for the "diamond"
- and "radial waves" patterns, respectively.
-
- to do (someday, maybe):
- - fix expose/redraw code: don't draw entire row if only part exposed
- - 8-bit (colormapped) X support
- - finish resizable checkerboard-gradient (sizes 4-128?)
- - use %.1023s to simplify truncation of title-bar string?
-
- ---------------------------------------------------------------------------
-
- Changelog:
- - 1.01: initial public release
- - 1.02: modified to allow abbreviated options; fixed char/uchar mismatch
- - 1.10: added support for non-default visuals; fixed X pixel-conversion
- - 1.11: added -usleep option for demos; fixed command-line parsing bug
- - 1.12: added -pause option for demos and testing
- - 1.20: added runtime MMX-enabling/disabling and new -mmx* options
- - 1.21: fixed some small X memory leaks (thanks to François Petitjean)
- - 1.22: fixed XFreeGC() crash bug (thanks to Patrick Welche)
- - 1.23: added -bgpat 0 mode (std white/gray checkerboard, 8x8 squares)
- - 1.30: added -loop option for -bgpat (ifdef FEATURE_LOOP); fixed bpp =
- 24; added support for X resources (thanks to Gerhard Niklasch)
- - 1.31: added code to skip unused chunks (thanks to Glenn Randers-Pehrson)
- - 1.32: added AMD64/EM64T support (__x86_64__); added basic expose/redraw
- handling
- - 2.00: dual-licensed (added GNU GPL)
- - 2.01: fixed 64-bit typo in readpng2.c; fixed -pause usage description
- - 2.02: fixed improper display of usage screen on PNG error(s); fixed
- unexpected-EOF and file-read-error cases; fixed Trace() cut-and-
- paste bugs
- - 2.03: deleted runtime MMX-enabling/disabling and obsolete -mmx* options

- wpng - simple PNG-writing program wpng.c
-
- This program converts certain NetPBM binary files (grayscale and RGB,
- maxval = 255) to PNG. Non-interlaced PNGs are written progressively;
- interlaced PNGs are read and written in one memory-intensive blast.
-
- Thanks to Jean-loup Gailly for providing the necessary trick to read
- interactive text from the keyboard while stdin is redirected. Thanks
- to Cosmin Truta for Cygwin fixes.
-
- NOTE: includes provisional support for PNM type "8" (portable alphamap)
- images, presumed to be a 32-bit interleaved RGBA format; no pro-
- vision for possible interleaved grayscale+alpha (16-bit) format.
- THIS IS UNLIKELY TO BECOME AN OFFICIAL NETPBM ALPHA FORMAT!
-
- to do:
- - delete output file if quit before calling any writepng routines
- - process backspace with -text option under DOS/Win? (currently get ^H)
-
- ---------------------------------------------------------------------------
-
- Changelog:
- - 1.01: initial public release
- - 1.02: modified to allow abbreviated options
- - 1.03: removed extraneous character from usage screen; fixed bug in
- command-line parsing
- - 1.04: fixed DOS/OS2/Win32 detection, including partial Cygwin fix
- (see http://home.att.net/~perlspinr/diffs/GregBook_cygwin.diff)
- - 2.00: dual-licensed (added GNU GPL)
-
- [REPORTED BUG (win32 only): "contrib/gregbook/wpng.c - cmd line
- dose not work! In order to do something useful I needed to redirect
- both input and output, with cygwin and with bcc32 as well. Under
- Linux, the same wpng appears to work fine. I don't know what is
- the problem."]

-express or implied warranty.
-
-
-Some history
-------------
-Soon after the creation of PNG in 1995, the need was felt for a set of
-pnmtopng / pngtopnm utilities. Independantly Alexander Lehmann and I
-(Willem van Schaik) started such a project. Luckily we discovered this
-and merged the two together into pnmtopng.tar.gz, which is available
-from a/o ftp://ftp.simplesystems.org/pub/libpng/png/.
-
-These two utilities have many, many options and make use of most of the
-features of PNG, like gamma, alpha, sbit, text-chunks, etc. This makes
-the utilities quite complex and by now not anymore very maintainable.
-When we wrote these programs, libpng was still in an early stage.
-Therefore, lots of the functionality that we put in our software can now
-be done using transform-functions in libpng.
-
-Finally, to compile these programs, you need to have installed and
-compiled three libraries: libpng, zlib and netpbm. Especially the latter
-makes the whole setup a bit bulky. But that's unavoidable given the many
-features of pnmtopng.
-
-
-What now
---------
-At this moment libpng is in a very stable state and can do much of the
-work done in pnmtopng. Also, pnmtopng needs to be upgraded to the new
-interface of libpng. Hence, it is time for a rewrite from the ground up
-of pnmtopng and pngtopnm. This will happen in the near future (stay
-tuned). The new package will get a different name to distinguish it from
-the old one: PngPlus.
-
-To experiment a bit with the new interface of libpng, I started off with
-a small prototype that contains only the basic functionality. It doesn't
-have any of the options to read or write special chunks and it will do
-no gamma correction. But this makes it also a simple program that is
-quite easy to understand and can serve well as a template for other
-software developments. (By now there are of course a couple of programs,
-like Greg Roelofs' rpng/wpng, that can be used just as good.)
-
-
-Can and can not
----------------
-As this is the small brother of the future PngPlus, I called this fellow
-PngMinus. Because I started this development in good-old Turbo-C, I
-avoided the use the netpbm library, which requires DOS extenders. Again,
-another reason to call it PngMinus (minus netpbm :-). So, part of the
-program are some elementary routines to read / write pgm- and ppm-files.
-It does not read b&w pbm-files.
-
-The downside of this approach is that you can not use them on images
-that require blocks of memory bigger than 64k (the DOS version). For
-larger images you will get an out-of-memory error.
-
-As said before, PngMinus doesn't correct for gamma. When reading
-png-files you can do this just as well by piping the output of png2pnm
-to pnmgamma, one of the standard PbmPlus tools. This same scenario will
-most probably also be followed in the full-blown future PngPlus, with
-the addition of course of the possibility to create gamma-chunks when
-writing png-files.
-
-On the other hand it supports alpha-channels. When reading a png-image
-you can write the alpha-channel into a pgm-file. And when creating an
-RGB+A png-image, you just combine a ppm-file with a corresponding
-pgm-file containing the alpha-channel. When reading, transparency chunks
-are converted into an alpha-channel and from there on treated the same
-way.
-
-Finally you can opt for writing ascii or binary pgm- and ppm-files. When
-the bit-depth is 16, the format will always be ascii.
-
-
-Using it
---------
-To distinguish them from pnmtopng and PngPlus, the utilities are named
-png2pnm and pnm2png (2 instead of to). The input- and output-files can
-be given as parameters or through redirection. Therefore the programs
-can be part of a pipe.
-
-To list the options type "png2pnm -h" or "pnm2png -h".
-
-
-Just like Scandinavian furniture
---------------------------------
-You have to put it together yourself. I did test the software under
-MS-DOS with Turbo-C 3.0 and under RedHat Linux 4.2 with gcc. In both
-cases I used libpng-1.0.4 and zlib-1.1.3. Later versions should be OK,
-however some older libpng versions have a bug in pngmem.c when using
-Turbo-C 3.0 (see below).
-
-You can build it using one of the two makefiles (make -f makefile.###)
-or use the batch/script files pngminus.bat / pngminus.sh. This assumes
-that you have built the libraries in ../libpng and ../zlib. Using Linux,
-make sure that you have built libpng with makefile.std and not
-makefile.linux (also called .lnx in earlier versions of libpng). The
-latter creates a .so shared-library, while the PngMinus makefile assumes
-a normal .a static library.
-
-If you create a ../pngsuite directory and then store the basn####.png
-files from PngSuite (http://www.schaik.com/pngsuite/) in there, you can
-test in one go the proper functioning of PngMinus, see png2pnm.bat and
-pnm2png.bat (or the .sh versions).
-
-
-Warranty
--------
-Please, remember that this was just a small experiment to learn a few
-things. It will have many unforeseen features <vbg>. Who said bugs? Use
-it when you are in need for something simple or when you want to start
-developing your own stuff.
-
-
-The Turbo bug
--------------
-** pngmem.old
- hptr = (png_byte huge *)((long)(hptr) & 0xfffffff0L);
- hptr += 16L;
-** pngmem.c
- hptr = (png_byte huge *)((long)(hptr) & 0xfffffff0L);
- hptr = hptr + 16L;
-**
-
-** pngmem.old
- png_ptr->offset_table_ptr[i] = (png_bytep)hptr;
- hptr += (png_uint_32)65536L;
-** pngmem.c
- png_ptr->offset_table_ptr[i] = (png_bytep)hptr;
- hptr = hptr + 65536L;

-Two images are by Glenn Randers-Pehrson, 2012
-
-Permission to use, copy, modify, and distribute these images for any
-purpose and without fee is hereby granted.
-
-The 15 "bas*.png" images are part of the much larger PngSuite test-set of
-images, available for developers of PNG supporting software. The
-complete set, available at http:/www.schaik.com/pngsuite/, contains
-a variety of images to test interlacing, gamma settings, ancillary
-chunks, etc.
-
-The "ft*.png" images are "free/libre" replacements for the transparent
-corresponding t*.png images in the PngSuite.
-
-The images in this directory represent the basic PNG color-types:
-grayscale (1-16 bit deep), full color (8 or 16 bit), paletted
-(1-8 bit) and grayscale or color images with alpha channel. You
-can use them to test the proper functioning of PNG software.

-Microsoft Developer Studio Build File, Format Version 6.00 for VisualPng
-------------------------------------------------------------------------
-
-Copyright 2000, Willem van Schaik.
-
-This code is released under the libpng license.
-For conditions of distribution and use, see the disclaimer
-and license in png.h
-
-As a PNG .dll demo VisualPng is finished. More features would only hinder
-the program's objective. However, further extensions (like support for other
-graphics formats) are in development. To get these, or for pre-compiled
-binaries, go to "http://www.schaik.com/png/visualpng.html".
-
-------------------------------------------------------------------------
-
-Assumes that
-
- libpng DLLs and LIBs are in ..\..\projects\msvc\win32\libpng
- zlib DLLs and LIBs are in ..\..\projects\msvc\win32\zlib
- libpng header files are in ..\..\..\libpng
- zlib header files are in ..\..\..\zlib
- the pngsuite images are in ..\pngsuite
-
-To build:
-
-1) On the main menu Select "Build|Set Active configuration".
- Choose the configuration that corresponds to the library you want to test.
- This library must have been built using the libpng MS project located in
- the "..\..\mscv" subdirectory.
-
-2) Select "Build|Clean"
-
-3) Select "Build|Rebuild All"
-
-4) After compiling and linking VisualPng will be started to view an image
- from the PngSuite directory. Press Ctrl-N (and Ctrl-V) for other images.
-
-
-To install:
-
-When distributing VisualPng (or a further development) the following options
-are available:
-
-1) Build the program with the configuration "Win32 LIB" and you only need to
- include the executable from the ./lib directory in your distribution.
-
-2) Build the program with the configuration "Win32 DLL" and you need to put
- in your distribution the executable from the ./dll directory and the dll's
- libpng1.dll, zlib.dll and msvcrt.dll. These need to be in the user's PATH.
-
-
-Willem van Schaik
-Calgary, June 6th 2000
-
-P.S. VisualPng was written based on preliminary work of:
-
- - Simon-Pierre Cadieux
- - Glenn Randers-Pehrson
- - Greg Roelofs

-http://www.nicemice.net/cexcept/
-Adam M. Costello
-http://www.nicemice.net/amc/
-
-An interface for exception-handling in ANSI C (C89 and subsequent ISO
-standards), developed jointly with Cosmin Truta.
-
- Copyright (c) 2000-2008 Adam M. Costello and Cosmin Truta.
- This software may be modified only if its author and version
- information is updated accurately, and may be redistributed
- only if accompanied by this unaltered notice. Subject to those
- restrictions, permission is granted to anyone to do anything
- with this software. The copyright holders make no guarantees
- regarding this software, and are not responsible for any damage
- resulting from its use.
-
-The cexcept interface is not compatible with and cannot interact
-with system exceptions (like division by zero or memory segmentation
-violation), compiler-generated exceptions (like C++ exceptions), or
-other exception-handling interfaces.
-
-When using this interface across multiple .c files, do not include
-this header file directly. Instead, create a wrapper header file that
-includes this header file and then invokes the define_exception_type
-macro (see below). The .c files should then include that header file.
-
-The interface consists of one type, one well-known name, and six macros.
-
-
-define_exception_type(type_name);
-
- This macro is used like an external declaration. It specifies
- the type of object that gets copied from the exception thrower to
- the exception catcher. The type_name can be any type that can be
- assigned to, that is, a non-constant arithmetic type, struct, union,
- or pointer. Examples:
-
- define_exception_type(int);
-
- enum exception { out_of_memory, bad_arguments, disk_full };
- define_exception_type(enum exception);
-
- struct exception { int code; const char *msg; };
- define_exception_type(struct exception);
-
- Because throwing an exception causes the object to be copied (not
- just once, but twice), programmers may wish to consider size when
- choosing the exception type.
-
-
-struct exception_context;
-
- This type may be used after the define_exception_type() macro has
- been invoked. A struct exception_context must be known to both
- the thrower and the catcher. It is expected that there be one
- context for each thread that uses exceptions. It would certainly
- be dangerous for multiple threads to access the same context.
- One thread can use multiple contexts, but that is likely to be
- confusing and not typically useful. The application can allocate
- this structure in any way it pleases--automatic, static, or dynamic.
- The application programmer should pretend not to know the structure
- members, which are subject to change.
-
-
-struct exception_context *the_exception_context;
-
- The Try/Catch and Throw statements (described below) implicitly
- refer to a context, using the name the_exception_context. It is
- the application's responsibility to make sure that this name yields
- the address of a mutable (non-constant) struct exception_context
- wherever those statements are used. Subject to that constraint, the
- application may declare a variable of this name anywhere it likes
- (inside a function, in a parameter list, or externally), and may
- use whatever storage class specifiers (static, extern, etc) or type
- qualifiers (const, volatile, etc) it likes. Examples:
-
- static struct exception_context
- * const the_exception_context = &foo;
-
- { struct exception_context *the_exception_context = bar; ... }
-
- int blah(struct exception_context *the_exception_context, ...);
-
- extern struct exception_context the_exception_context[1];
-
- The last example illustrates a trick that avoids creating a pointer
- object separate from the structure object.
-
- The name could even be a macro, for example:
-
- struct exception_context ec_array[numthreads];
- #define the_exception_context (ec_array + thread_id)
-
- Be aware that the_exception_context is used several times by the
- Try/Catch/Throw macros, so it shouldn't be expensive or have side
- effects. The expansion must be a drop-in replacement for an
- identifier, so it's safest to put parentheses around it.
-
-
-void init_exception_context(struct exception_context *ec);
-
- For context structures allocated statically (by an external
- definition or using the "static" keyword), the implicit
- initialization to all zeros is sufficient, but contexts allocated
- by other means must be initialized using this macro before they
- are used by a Try/Catch statement. It does no harm to initialize
- a context more than once (by using this macro on a statically
- allocated context, or using this macro twice on the same context),
- but a context must not be re-initialized after it has been used by a
- Try/Catch statement.
-
-
-Try statement
-Catch (expression) statement
-
- The Try/Catch/Throw macros are capitalized in order to avoid
- confusion with the C++ keywords, which have subtly different
- semantics.
-
- A Try/Catch statement has a syntax similar to an if/else statement,
- except that the parenthesized expression goes after the second
- keyword rather than the first. As with if/else, there are two
- clauses, each of which may be a simple statement ending with a
- semicolon or a brace-enclosed compound statement. But whereas
- the else clause is optional, the Catch clause is required. The
- expression must be a modifiable lvalue (something capable of being
- assigned to) of the same type (disregarding type qualifiers) that
- was passed to define_exception_type().
-
- If a Throw that uses the same exception context as the Try/Catch is
- executed within the Try clause (typically within a function called
- by the Try clause), and the exception is not caught by a nested
- Try/Catch statement, then a copy of the exception will be assigned
- to the expression, and control will jump to the Catch clause. If no
- such Throw is executed, then the assignment is not performed, and
- the Catch clause is not executed.
-
- The expression is not evaluated unless and until the exception is
- caught, which is significant if it has side effects, for example:
-
- Try foo();
- Catch (p[++i].e) { ... }
-
- IMPORTANT: Jumping into or out of a Try clause (for example via
- return, break, continue, goto, longjmp) is forbidden--the compiler
- will not complain, but bad things will happen at run-time. Jumping
- into or out of a Catch clause is okay, and so is jumping around
- inside a Try clause. In many cases where one is tempted to return
- from a Try clause, it will suffice to use Throw, and then return
- from the Catch clause. Another option is to set a flag variable and
- use goto to jump to the end of the Try clause, then check the flag
- after the Try/Catch statement.
-
- IMPORTANT: The values of any non-volatile automatic variables
- changed within the Try clause are undefined after an exception is
- caught. Therefore, variables modified inside the Try block whose
- values are needed later outside the Try block must either use static
- storage or be declared with the "volatile" type qualifier.
-
-
-Throw expression;
-
- A Throw statement is very much like a return statement, except that
- the expression is required. Whereas return jumps back to the place
- where the current function was called, Throw jumps back to the Catch
- clause of the innermost enclosing Try clause. The expression must
- be compatible with the type passed to define_exception_type(). The
- exception must be caught, otherwise the program may crash.
-
- Slight limitation: If the expression is a comma-expression, it must
- be enclosed in parentheses.
-
-
-Try statement
-Catch_anonymous statement
-
- When the value of the exception is not needed, a Try/Catch statement
- can use Catch_anonymous instead of Catch (expression).
-
-
-Everything below this point is for the benefit of the compiler. The
-application programmer should pretend not to know any of it, because it
-is subject to change.

-I. Introduction
-
-This file describes how to use and modify the PNG reference library
-(known as libpng) for your own use. There are five sections to this
-file: introduction, structures, reading, writing, and modification and
-configuration notes for various special platforms. In addition to this
-file, example.c is a good starting point for using the library, as
-it is heavily commented and should include everything most people
-will need. We assume that libpng is already installed; see the
-INSTALL file for instructions on how to install libpng.
-
-For examples of libpng usage, see the files "example.c", "pngtest.c",
-and the files in the "contrib" directory, all of which are included in
-the libpng distribution.
-
-Libpng was written as a companion to the PNG specification, as a way
-of reducing the amount of time and effort it takes to support the PNG
-file format in application programs.
-
-The PNG specification (second edition), November 2003, is available as
-a W3C Recommendation and as an ISO Standard (ISO/IEC 15948:2003 (E)) at
-<http://www.w3.org/TR/2003/REC-PNG-20031110/
-The W3C and ISO documents have identical technical content.
-
-The PNG-1.2 specification is available at
-<http://www.libpng.org/pub/png/documents/>. It is technically equivalent
-to the PNG specification (second edition) but has some additional material.
-
-The PNG-1.0 specification is available
-as RFC 2083 <http://www.libpng.org/pub/png/documents/> and as a
-W3C Recommendation <http://www.w3.org/TR/REC.png.html>.
-
-Some additional chunks are described in the special-purpose public chunks
-documents at <http://www.libpng.org/pub/png/documents/>.
-
-Other information
-about PNG, and the latest version of libpng, can be found at the PNG home
-page, <http://www.libpng.org/pub/png/>.
-
-Most users will not have to modify the library significantly; advanced
-users may want to modify it more. All attempts were made to make it as
-complete as possible, while keeping the code easy to understand.
-Currently, this library only supports C. Support for other languages
-is being considered.
-
-Libpng has been designed to handle multiple sessions at one time,
-to be easily modifiable, to be portable to the vast majority of
-machines (ANSI, K&R, 16-, 32-, and 64-bit) available, and to be easy
-to use. The ultimate goal of libpng is to promote the acceptance of
-the PNG file format in whatever way possible. While there is still
-work to be done (see the TODO file), libpng should cover the
-majority of the needs of its users.
-
-Libpng uses zlib for its compression and decompression of PNG files.
-Further information about zlib, and the latest version of zlib, can
-be found at the zlib home page, <http://www.info-zip.org/pub/infozip/zlib/>.
-The zlib compression utility is a general purpose utility that is
-useful for more than PNG files, and can be used without libpng.
-See the documentation delivered with zlib for more details.
-You can usually find the source files for the zlib utility wherever you
-find the libpng source files.
-
-Libpng is thread safe, provided the threads are using different
-instances of the structures. Each thread should have its own
-png_struct and png_info instances, and thus its own image.
-Libpng does not protect itself against two threads using the
-same instance of a structure.
-
-II. Structures
-
-There are two main structures that are important to libpng, png_struct
-and png_info. The first, png_struct, is an internal structure that
-will not, for the most part, be used by a user except as the first
-variable passed to every libpng function call.
-
-The png_info structure is designed to provide information about the
-PNG file. At one time, the fields of png_info were intended to be
-directly accessible to the user. However, this tended to cause problems
-with applications using dynamically loaded libraries, and as a result
-a set of interface functions for png_info (the png_get_*() and png_set_*()
-functions) was developed. The fields of png_info are still available for
-older applications, but it is suggested that applications use the new
-interfaces if at all possible.
-
-Applications that do make direct access to the members of png_struct (except
-for png_ptr->jmpbuf) must be recompiled whenever the library is updated,
-and applications that make direct access to the members of png_info must
-be recompiled if they were compiled or loaded with libpng version 1.0.6,
-in which the members were in a different order. In version 1.0.7, the
-members of the png_info structure reverted to the old order, as they were
-in versions 0.97c through 1.0.5. Starting with version 2.0.0, both
-structures are going to be hidden, and the contents of the structures will
-only be accessible through the png_get/png_set functions.
-
-The png.h header file is an invaluable reference for programming with libpng.
-And while I'm on the topic, make sure you include the libpng header file:
-
-#include <png.h>
-
-III. Reading
-
-We'll now walk you through the possible functions to call when reading
-in a PNG file sequentially, briefly explaining the syntax and purpose
-of each one. See example.c and png.h for more detail. While
-progressive reading is covered in the next section, you will still
-need some of the functions discussed in this section to read a PNG
-file.
-
-Setup
-
-You will want to do the I/O initialization(*) before you get into libpng,
-so if it doesn't work, you don't have much to undo. Of course, you
-will also want to insure that you are, in fact, dealing with a PNG
-file. Libpng provides a simple check to see if a file is a PNG file.
-To use it, pass in the first 1 to 8 bytes of the file to the function
-png_sig_cmp(), and it will return 0 (false) if the bytes match the
-corresponding bytes of the PNG signature, or nonzero (true) otherwise.
-Of course, the more bytes you pass in, the greater the accuracy of the
-prediction.
-
-If you are intending to keep the file pointer open for use in libpng,
-you must ensure you don't read more than 8 bytes from the beginning
-of the file, and you also have to make a call to png_set_sig_bytes_read()
-with the number of bytes you read from the beginning. Libpng will
-then only check the bytes (if any) that your program didn't read.
-
-(*): If you are not using the standard I/O functions, you will need
-to replace them with custom functions. See the discussion under
-Customizing libpng.
-
-
- FILE *fp = fopen(file_name, "rb");
- if (!fp)
- {
- return (ERROR);
- }
- fread(header, 1, number, fp);
- is_png = !png_sig_cmp(header, 0, number);
- if (!is_png)
- {
- return (NOT_PNG);
- }
-
-
-Next, png_struct and png_info need to be allocated and initialized. In
-order to ensure that the size of these structures is correct even with a
-dynamically linked libpng, there are functions to initialize and
-allocate the structures. We also pass the library version, optional
-pointers to error handling functions, and a pointer to a data struct for
-use by the error functions, if necessary (the pointer and functions can
-be NULL if the default error handlers are to be used). See the section
-on Changes to Libpng below regarding the old initialization functions.
-The structure allocation functions quietly return NULL if they fail to
-create the structure, so your application should check for that.
-
- png_structp png_ptr = png_create_read_struct
- (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
- user_error_fn, user_warning_fn);
- if (!png_ptr)
- return (ERROR);
-
- png_infop info_ptr = png_create_info_struct(png_ptr);
- if (!info_ptr)
- {
- png_destroy_read_struct(&png_ptr,
- (png_infopp)NULL, (png_infopp)NULL);
- return (ERROR);
- }
-
- png_infop end_info = png_create_info_struct(png_ptr);
- if (!end_info)
- {
- png_destroy_read_struct(&png_ptr, &info_ptr,
- (png_infopp)NULL);
- return (ERROR);
- }
-
-If you want to use your own memory allocation routines,
-define PNG_USER_MEM_SUPPORTED and use
-png_create_read_struct_2() instead of png_create_read_struct():
-
- png_structp png_ptr = png_create_read_struct_2
- (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
- user_error_fn, user_warning_fn, (png_voidp)
- user_mem_ptr, user_malloc_fn, user_free_fn);
-
-The error handling routines passed to png_create_read_struct()
-and the memory alloc/free routines passed to png_create_struct_2()
-are only necessary if you are not using the libpng supplied error
-handling and memory alloc/free functions.
-
-When libpng encounters an error, it expects to longjmp back
-to your routine. Therefore, you will need to call setjmp and pass
-your png_jmpbuf(png_ptr). If you read the file from different
-routines, you will need to update the jmpbuf field every time you enter
-a new routine that will call a png_*() function.
-
-See your documentation of setjmp/longjmp for your compiler for more
-information on setjmp/longjmp. See the discussion on libpng error
-handling in the Customizing Libpng section below for more information
-on the libpng error handling. If an error occurs, and libpng longjmp's
-back to your setjmp, you will want to call png_destroy_read_struct() to
-free any memory.
-
- if (setjmp(png_jmpbuf(png_ptr)))
- {
- png_destroy_read_struct(&png_ptr, &info_ptr,
- &end_info);
- fclose(fp);
- return (ERROR);
- }
-
-If you would rather avoid the complexity of setjmp/longjmp issues,
-you can compile libpng with PNG_NO_SETJMP, in which case
-errors will result in a call to PNG_ABORT() which defaults to abort().
-
-You can #define PNG_ABORT() to a function that does something
-more useful than abort(), as long as your function does not
-return.
-
-Now you need to set up the input code. The default for libpng is to
-use the C function fread(). If you use this, you will need to pass a
-valid FILE * in the function png_init_io(). Be sure that the file is
-opened in binary mode. If you wish to handle reading data in another
-way, you need not call the png_init_io() function, but you must then
-implement the libpng I/O methods discussed in the Customizing Libpng
-section below.
-
- png_init_io(png_ptr, fp);
-
-If you had previously opened the file and read any of the signature from
-the beginning in order to see if this was a PNG file, you need to let
-libpng know that there are some bytes missing from the start of the file.
-
- png_set_sig_bytes(png_ptr, number);
-
-You can change the zlib compression buffer size to be used while
-reading compressed data with
-
- png_set_compression_buffer_size(png_ptr, buffer_size);
-
-where the default size is 8192 bytes. Note that the buffer size
-is changed immediately and the buffer is reallocated immediately,
-instead of setting a flag to be acted upon later.
-
-Setting up callback code
-
-You can set up a callback function to handle any unknown chunks in the
-input stream. You must supply the function
-
- read_chunk_callback(png_structp png_ptr,
- png_unknown_chunkp chunk);
- {
- /* The unknown chunk structure contains your
- chunk data, along with similar data for any other
- unknown chunks: */
-
- png_byte name[5];
- png_byte *data;
- png_size_t size;
-
- /* Note that libpng has already taken care of
- the CRC handling */
-
- /* put your code here. Search for your chunk in the
- unknown chunk structure, process it, and return one
- of the following: */
-
- return (-n); /* chunk had an error */
- return (0); /* did not recognize */
- return (n); /* success */
- }
-
-(You can give your function another name that you like instead of
-"read_chunk_callback")
-
-To inform libpng about your function, use
-
- png_set_read_user_chunk_fn(png_ptr, user_chunk_ptr,
- read_chunk_callback);
-
-This names not only the callback function, but also a user pointer that
-you can retrieve with
-
- png_get_user_chunk_ptr(png_ptr);
-
-If you call the png_set_read_user_chunk_fn() function, then all unknown
-chunks will be saved when read, in case your callback function will need
-one or more of them. This behavior can be changed with the
-png_set_keep_unknown_chunks() function, described below.
-
-At this point, you can set up a callback function that will be
-called after each row has been read, which you can use to control
-a progress meter or the like. It's demonstrated in pngtest.c.
-You must supply a function
-
- void read_row_callback(png_structp png_ptr,
- png_uint_32 row, int pass);
- {
- /* put your code here */
- }
-
-(You can give it another name that you like instead of "read_row_callback")
-
-To inform libpng about your function, use
-
- png_set_read_status_fn(png_ptr, read_row_callback);
-
-Unknown-chunk handling
-
-Now you get to set the way the library processes unknown chunks in the
-input PNG stream. Both known and unknown chunks will be read. Normal
-behavior is that known chunks will be parsed into information in
-various info_ptr members while unknown chunks will be discarded. This
-behavior can be wasteful if your application will never use some known
-chunk types. To change this, you can call:
-
- png_set_keep_unknown_chunks(png_ptr, keep,
- chunk_list, num_chunks);
- keep - 0: default unknown chunk handling
- 1: ignore; do not keep
- 2: keep only if safe-to-copy
- 3: keep even if unsafe-to-copy
- You can use these definitions:
- PNG_HANDLE_CHUNK_AS_DEFAULT 0
- PNG_HANDLE_CHUNK_NEVER 1
- PNG_HANDLE_CHUNK_IF_SAFE 2
- PNG_HANDLE_CHUNK_ALWAYS 3
- chunk_list - list of chunks affected (a byte string,
- five bytes per chunk, NULL or '\0' if
- num_chunks is 0)
- num_chunks - number of chunks affected; if 0, all
- unknown chunks are affected. If nonzero,
- only the chunks in the list are affected
-
-Unknown chunks declared in this way will be saved as raw data onto a
-list of png_unknown_chunk structures. If a chunk that is normally
-known to libpng is named in the list, it will be handled as unknown,
-according to the "keep" directive. If a chunk is named in successive
-instances of png_set_keep_unknown_chunks(), the final instance will
-take precedence. The IHDR and IEND chunks should not be named in
-chunk_list; if they are, libpng will process them normally anyway.
-
-Here is an example of the usage of png_set_keep_unknown_chunks(),
-where the private "vpAg" chunk will later be processed by a user chunk
-callback function:
-
- png_byte vpAg[5]={118, 112, 65, 103, (png_byte) '\0'};
-
- #if defined(PNG_UNKNOWN_CHUNKS_SUPPORTED)
- png_byte unused_chunks[]=
- {
- 104, 73, 83, 84, (png_byte) '\0', /* hIST */
- 105, 84, 88, 116, (png_byte) '\0', /* iTXt */
- 112, 67, 65, 76, (png_byte) '\0', /* pCAL */
- 115, 67, 65, 76, (png_byte) '\0', /* sCAL */
- 115, 80, 76, 84, (png_byte) '\0', /* sPLT */
- 116, 73, 77, 69, (png_byte) '\0', /* tIME */
- };
- #endif
-
- ...
-
- #if defined(PNG_UNKNOWN_CHUNKS_SUPPORTED)
- /* ignore all unknown chunks: */
- png_set_keep_unknown_chunks(read_ptr, 1, NULL, 0);
- /* except for vpAg: */
- png_set_keep_unknown_chunks(read_ptr, 2, vpAg, 1);
- /* also ignore unused known chunks: */
- png_set_keep_unknown_chunks(read_ptr, 1, unused_chunks,
- (int)sizeof(unused_chunks)/5);
- #endif
-
-User limits
-
-The PNG specification allows the width and height of an image to be as
-large as 2^31-1 (0x7fffffff), or about 2.147 billion rows and columns.
-Since very few applications really need to process such large images,
-we have imposed an arbitrary 1-million limit on rows and columns.
-Larger images will be rejected immediately with a png_error() call. If
-you wish to override this limit, you can use
-
- png_set_user_limits(png_ptr, width_max, height_max);
-
-to set your own limits, or use width_max = height_max = 0x7fffffffL
-to allow all valid dimensions (libpng may reject some very large images
-anyway because of potential buffer overflow conditions).
-
-You should put this statement after you create the PNG structure and
-before calling png_read_info(), png_read_png(), or png_process_data().
-If you need to retrieve the limits that are being applied, use
-
- width_max = png_get_user_width_max(png_ptr);
- height_max = png_get_user_height_max(png_ptr);
-
-The PNG specification sets no limit on the number of ancillary chunks
-allowed in a PNG datastream. You can impose a limit on the total number
-of sPLT, tEXt, iTXt, zTXt, and unknown chunks that will be stored, with
-
- png_set_chunk_cache_max(png_ptr, user_chunk_cache_max);
-
-where 0x7fffffffL means unlimited. You can retrieve this limit with
-
- chunk_cache_max = png_get_chunk_cache_max(png_ptr);
-
-This limit also applies to the number of buffers that can be allocated
-by png_decompress_chunk() while decompressing iTXt, zTXt, and iCCP chunks.
-
-You can also set a limit on the amount of memory that a compressed chunk
-other than IDAT can occupy, with
-
- png_set_chunk_malloc_max(png_ptr, user_chunk_malloc_max);
-
-and you can retrieve the limit with
-
- chunk_malloc_max = png_get_chunk_malloc_max(png_ptr);
-
-Any chunks that would cause either of these limits to be exceeded will
-be ignored.
-
-The high-level read interface
-
-At this point there are two ways to proceed; through the high-level
-read interface, or through a sequence of low-level read operations.
-You can use the high-level interface if (a) you are willing to read
-the entire image into memory, and (b) the input transformations
-you want to do are limited to the following set:
-
- PNG_TRANSFORM_IDENTITY No transformation
- PNG_TRANSFORM_STRIP_16 Strip 16-bit samples to
- 8 bits
- PNG_TRANSFORM_STRIP_ALPHA Discard the alpha channel
- PNG_TRANSFORM_PACKING Expand 1, 2 and 4-bit
- samples to bytes
- PNG_TRANSFORM_PACKSWAP Change order of packed
- pixels to LSB first
- PNG_TRANSFORM_EXPAND Perform set_expand()
- PNG_TRANSFORM_INVERT_MONO Invert monochrome images
- PNG_TRANSFORM_SHIFT Normalize pixels to the
- sBIT depth
- PNG_TRANSFORM_BGR Flip RGB to BGR, RGBA
- to BGRA
- PNG_TRANSFORM_SWAP_ALPHA Flip RGBA to ARGB or GA
- to AG
- PNG_TRANSFORM_INVERT_ALPHA Change alpha from opacity
- to transparency
- PNG_TRANSFORM_SWAP_ENDIAN Byte-swap 16-bit samples
- PNG_TRANSFORM_GRAY_TO_RGB Expand grayscale samples
- to RGB (or GA to RGBA)
-
-(This excludes setting a background color, doing gamma transformation,
-quantizing, and setting filler.) If this is the case, simply do this:
-
- png_read_png(png_ptr, info_ptr, png_transforms, NULL)
-
-where png_transforms is an integer containing the bitwise OR of some
-set of transformation flags. This call is equivalent to png_read_info(),
-followed the set of transformations indicated by the transform mask,
-then png_read_image(), and finally png_read_end().
-
-(The final parameter of this call is not yet used. Someday it might point
-to transformation parameters required by some future input transform.)
-
-You must use png_transforms and not call any png_set_transform() functions
-when you use png_read_png().
-
-After you have called png_read_png(), you can retrieve the image data
-with
-
- row_pointers = png_get_rows(png_ptr, info_ptr);
-
-where row_pointers is an array of pointers to the pixel data for each row:
-
- png_bytep row_pointers[height];
-
-If you know your image size and pixel size ahead of time, you can allocate
-row_pointers prior to calling png_read_png() with
-
- if (height > PNG_UINT_32_MAX/png_sizeof(png_byte))
- png_error (png_ptr,
- "Image is too tall to process in memory");
- if (width > PNG_UINT_32_MAX/pixel_size)
- png_error (png_ptr,
- "Image is too wide to process in memory");
- row_pointers = png_malloc(png_ptr,
- height*png_sizeof(png_bytep));
- for (int i=0; i<height, i++)
- row_pointers[i]=NULL; /* security precaution */
- for (int i=0; i<height, i++)
- row_pointers[i]=png_malloc(png_ptr,
- width*pixel_size);
- png_set_rows(png_ptr, info_ptr, &row_pointers);
-
-Alternatively you could allocate your image in one big block and define
-row_pointers[i] to point into the proper places in your block.
-
-If you use png_set_rows(), the application is responsible for freeing
-row_pointers (and row_pointers[i], if they were separately allocated).
-
-If you don't allocate row_pointers ahead of time, png_read_png() will
-do it, and it'll be free'ed when you call png_destroy_*().
-
-The low-level read interface
-
-If you are going the low-level route, you are now ready to read all
-the file information up to the actual image data. You do this with a
-call to png_read_info().
-
- png_read_info(png_ptr, info_ptr);
-
-This will process all chunks up to but not including the image data.
-
-Querying the info structure
-
-Functions are used to get the information from the info_ptr once it
-has been read. Note that these fields may not be completely filled
-in until png_read_end() has read the chunk data following the image.
-
- png_get_IHDR(png_ptr, info_ptr, &width, &height,
- &bit_depth, &color_type, &interlace_type,
- &compression_type, &filter_method);
-
- width - holds the width of the image
- in pixels (up to 2^31).
- height - holds the height of the image
- in pixels (up to 2^31).
- bit_depth - holds the bit depth of one of the
- image channels. (valid values are
- 1, 2, 4, 8, 16 and depend also on
- the color_type. See also
- significant bits (sBIT) below).
- color_type - describes which color/alpha channels
- are present.
- PNG_COLOR_TYPE_GRAY
- (bit depths 1, 2, 4, 8, 16)
- PNG_COLOR_TYPE_GRAY_ALPHA
- (bit depths 8, 16)
- PNG_COLOR_TYPE_PALETTE
- (bit depths 1, 2, 4, 8)

- PNG_COLOR_TYPE_RGB_ALPHA
- (bit_depths 8, 16)
-
- PNG_COLOR_MASK_PALETTE
- PNG_COLOR_MASK_COLOR
- PNG_COLOR_MASK_ALPHA
-
- interlace_type - (PNG_INTERLACE_NONE or
- PNG_INTERLACE_ADAM7)
-
- compression_type - (must be PNG_COMPRESSION_TYPE_BASE
- for PNG 1.0)
-
- filter_method - (must be PNG_FILTER_TYPE_BASE
- for PNG 1.0, and can also be
- PNG_INTRAPIXEL_DIFFERENCING if
- the PNG datastream is embedded in
- a MNG-1.0 datastream)
-
- Any or all of interlace_type, compression_type, or
- filter_method can be NULL if you are
- not interested in their values.
-
- Note that png_get_IHDR() returns 32-bit data into
- the application's width and height variables.
- This is an unsafe situation if these are 16-bit
- variables. In such situations, the
- png_get_image_width() and png_get_image_height()
- functions described below are safer.
-
- width = png_get_image_width(png_ptr,
- info_ptr);
- height = png_get_image_height(png_ptr,
- info_ptr);
- bit_depth = png_get_bit_depth(png_ptr,
- info_ptr);
- color_type = png_get_color_type(png_ptr,
- info_ptr);
- interlace_type = png_get_interlace_type(png_ptr,
- info_ptr);
- compression_type = png_get_compression_type(png_ptr,
- info_ptr);
- filter_method = png_get_filter_type(png_ptr,
- info_ptr);
-
- channels = png_get_channels(png_ptr, info_ptr);
- channels - number of channels of info for the
- color type (valid values are 1 (GRAY,
- PALETTE), 2 (GRAY_ALPHA), 3 (RGB),
- 4 (RGB_ALPHA or RGB + filler byte))
- rowbytes = png_get_rowbytes(png_ptr, info_ptr);
- rowbytes - number of bytes needed to hold a row
-
- signature = png_get_signature(png_ptr, info_ptr);
- signature - holds the signature read from the
- file (if any). The data is kept in
- the same offset it would be if the
- whole signature were read (i.e. if an
- application had already read in 4
- bytes of signature before starting
- libpng, the remaining 4 bytes would
- be in signature[4] through signature[7]
- (see png_set_sig_bytes())).
-
-These are also important, but their validity depends on whether the chunk
-has been read. The png_get_valid(png_ptr, info_ptr, PNG_INFO_<chunk>) and
-png_get_<chunk>(png_ptr, info_ptr, ...) functions return non-zero if the
-data has been read, or zero if it is missing. The parameters to the
-png_get_<chunk> are set directly if they are simple data types, or a
-pointer into the info_ptr is returned for any complex types.
-

- &num_palette);
- palette - the palette for the file
- (array of png_color)

- at (PNG_INFO_gAMA)
-
- png_get_sRGB(png_ptr, info_ptr, &srgb_intent);
- srgb_intent - the rendering intent (PNG_INFO_sRGB)
- The presence of the sRGB chunk
- means that the pixel data is in the
- sRGB color space. This chunk also
- implies specific values of gAMA and
- cHRM.
-
- png_get_iCCP(png_ptr, info_ptr, &name,
- &compression_type, &profile, &proflen);
- name - The profile name.
- compression_type - The compression type; always
- PNG_COMPRESSION_TYPE_BASE for PNG 1.0.
- You may give NULL to this argument to
- ignore it.
- profile - International Color Consortium color
- profile data. May contain NULs.
- proflen - length of profile data in bytes.
-
- png_get_sBIT(png_ptr, info_ptr, &sig_bit);

- (PNG_INFO_sBIT) each of the gray,
- red, green, and blue channels,
- whichever are appropriate for the
- given color type (png_color_16)
-
- png_get_tRNS(png_ptr, info_ptr, &trans_alpha,

- comments
- text_ptr[i].compression - type of compression used
- on "text" PNG_TEXT_COMPRESSION_NONE
- PNG_TEXT_COMPRESSION_zTXt
- PNG_ITXT_COMPRESSION_NONE
- PNG_ITXT_COMPRESSION_zTXt
- text_ptr[i].key - keyword for comment. Must contain

- members of the text_ptr structure only exist
- when the library is built with iTXt chunk support.
-
- num_text - number of comments (same as
- num_comments; you can put NULL here
- to avoid the duplication)
- Note while png_set_text() will accept text, language,
- and translated keywords that can be NULL pointers, the
- structure returned by png_get_text will always contain
- regular zero-terminated C strings. They might be
- empty strings but they will never be NULL pointers.
-
- num_spalettes = png_get_sPLT(png_ptr, info_ptr,
- &palette_ptr);
- palette_ptr - array of palette structures holding
- contents of one or more sPLT chunks
- read.
- num_spalettes - number of sPLT chunks read.

-
- png_get_sCAL(png_ptr, info_ptr, &unit, &width,

- (width and height are doubles)
-
- png_get_sCAL_s(png_ptr, info_ptr, &unit, &width,
- &height)
- unit - physical scale units (an integer)

-
- num_unknown_chunks = png_get_unknown_chunks(png_ptr,
- info_ptr, &unknowns)
- unknowns - array of png_unknown_chunk
- structures holding unknown chunks
- unknowns[i].name - name of unknown chunk
- unknowns[i].data - data of unknown chunk
- unknowns[i].size - size of unknown chunk's data
- unknowns[i].location - position of chunk in file
-
- The value of "i" corresponds to the order in which the
- chunks were read from the PNG file or inserted with the
- png_set_unknown_chunks() function.
-
-The data from the pHYs chunk can be retrieved in several convenient
-forms:
-
- res_x = png_get_x_pixels_per_meter(png_ptr,
- info_ptr)
- res_y = png_get_y_pixels_per_meter(png_ptr,
- info_ptr)
- res_x_and_y = png_get_pixels_per_meter(png_ptr,
- info_ptr)
- res_x = png_get_x_pixels_per_inch(png_ptr,
- info_ptr)
- res_y = png_get_y_pixels_per_inch(png_ptr,
- info_ptr)
- res_x_and_y = png_get_pixels_per_inch(png_ptr,
- info_ptr)
- aspect_ratio = png_get_pixel_aspect_ratio(png_ptr,
- info_ptr)
-
- (Each of these returns 0 [signifying "unknown"] if
- the data is not present or if res_x is 0;
- res_x_and_y is 0 if res_x != res_y)
-
-The data from the oFFs chunk can be retrieved in several convenient
-forms:
-
- x_offset = png_get_x_offset_microns(png_ptr, info_ptr);
- y_offset = png_get_y_offset_microns(png_ptr, info_ptr);
- x_offset = png_get_x_offset_inches(png_ptr, info_ptr);
- y_offset = png_get_y_offset_inches(png_ptr, info_ptr);
-
- (Each of these returns 0 [signifying "unknown" if both
- x and y are 0] if the data is not present or if the
- chunk is present but the unit is the pixel)
-
-For more information, see the png_info definition in png.h and the
-PNG specification for chunk contents. Be careful with trusting
-rowbytes, as some of the transformations could increase the space
-needed to hold a row (expand, filler, gray_to_rgb, etc.).
-See png_read_update_info(), below.
-
-A quick word about text_ptr and num_text. PNG stores comments in
-keyword/text pairs, one pair per chunk, with no limit on the number
-of text chunks, and a 2^31 byte limit on their size. While there are
-suggested keywords, there is no requirement to restrict the use to these
-strings. It is strongly suggested that keywords and text be sensible
-to humans (that's the point), so don't use abbreviations. Non-printing
-symbols are not allowed. See the PNG specification for more details.
-There is also no requirement to have text after the keyword.
-
-Keywords should be limited to 79 Latin-1 characters without leading or
-trailing spaces, but non-consecutive spaces are allowed within the
-keyword. It is possible to have the same keyword any number of times.
-The text_ptr is an array of png_text structures, each holding a
-pointer to a language string, a pointer to a keyword and a pointer to
-a text string. The text string, language code, and translated
-keyword may be empty or NULL pointers. The keyword/text
-pairs are put into the array in the order that they are received.
-However, some or all of the text chunks may be after the image, so, to
-make sure you have read all the text chunks, don't mess with these
-until after you read the stuff after the image. This will be
-mentioned again below in the discussion that goes with png_read_end().
-
-Input transformations
-
-After you've read the header information, you can set up the library
-to handle any special transformations of the image data. The various
-ways to transform the data will be described in the order that they
-should occur. This is important, as some of these change the color
-type and/or bit depth of the data, and some others only work on
-certain color types and bit depths. Even though each transformation
-checks to see if it has data that it can do something with, you should
-make sure to only enable a transformation if it will be valid for the
-data. For example, don't swap red and blue on grayscale data.
-
-The colors used for the background and transparency values should be
-supplied in the same format/depth as the current image data. They
-are stored in the same format/depth as the image data in a bKGD or tRNS
-chunk, so this is what libpng expects for this data. The colors are
-transformed to keep in sync with the image data when an application
-calls the png_read_update_info() routine (see below).
-
-Data will be decoded into the supplied row buffers packed into bytes
-unless the library has been told to transform it into another format.
-For example, 4 bit/pixel paletted or grayscale data will be returned
-2 pixels/byte with the leftmost pixel in the high-order bits of the
-byte, unless png_set_packing() is called. 8-bit RGB data will be stored
-in RGB RGB RGB format unless png_set_filler() or png_set_add_alpha()
-is called to insert filler bytes, either before or after each RGB triplet.
-16-bit RGB data will be returned RRGGBB RRGGBB, with the most significant
-byte of the color value first, unless png_set_strip_16() is called to
-transform it to regular RGB RGB triplets, or png_set_filler() or
-png_set_add alpha() is called to insert filler bytes, either before or
-after each RRGGBB triplet. Similarly, 8-bit or 16-bit grayscale data can
-be modified with
-png_set_filler(), png_set_add_alpha(), or png_set_strip_16().
-
-The following code transforms grayscale images of less than 8 to 8 bits,
-changes paletted images to RGB, and adds a full alpha channel if there is
-transparency information in a tRNS chunk. This is most useful on
-grayscale images with bit depths of 2 or 4 or if there is a multiple-image
-viewing application that wishes to treat all images in the same way.
-
- if (color_type == PNG_COLOR_TYPE_PALETTE)
- png_set_palette_to_rgb(png_ptr);
-
- if (color_type == PNG_COLOR_TYPE_GRAY &&
- bit_depth < 8) png_set_expand_gray_1_2_4_to_8(png_ptr);
-
- if (png_get_valid(png_ptr, info_ptr,
- PNG_INFO_tRNS)) png_set_tRNS_to_alpha(png_ptr);
-
-These three functions are actually aliases for png_set_expand(), added
-in libpng version 1.0.4, with the function names expanded to improve code
-readability. In some future version they may actually do different
-things.
-
-As of libpng version 1.2.9, png_set_expand_gray_1_2_4_to_8() was
-added. It expands the sample depth without changing tRNS to alpha.
-
-As of libpng version 1.4.12, not all possible expansions are supported.
-
-In the following table, the 01 means grayscale with depth<8, 31 means
-indexed with depth<8, other numerals represent the color type, "T" means
-the tRNS chunk is present, A means an alpha channel is present, and O
-means tRNS or alpha is present but all pixels in the image are opaque.

-
-PNG can have files with 16 bits per channel. If you only can handle
-8 bits per channel, this will strip the pixels down to 8 bit.
-
- if (bit_depth == 16)
- png_set_strip_16(png_ptr);
-
-If, for some reason, you don't need the alpha channel on an image,
-and you want to remove it rather than combining it with the background
-(but the image author certainly had in mind that you *would* combine
-it with the background, so that's what you should probably do):
-
- if (color_type & PNG_COLOR_MASK_ALPHA)
- png_set_strip_alpha(png_ptr);
-
-In PNG files, the alpha channel in an image
-is the level of opacity. If you need the alpha channel in an image to
-be the level of transparency instead of opacity, you can invert the
-alpha channel (or the tRNS chunk data) after it's read, so that 0 is
-fully opaque and 255 (in 8-bit or paletted images) or 65535 (in 16-bit
-images) is fully transparent, with
-
- png_set_invert_alpha(png_ptr);
-
-PNG files pack pixels of bit depths 1, 2, and 4 into bytes as small as
-they can, resulting in, for example, 8 pixels per byte for 1 bit
-files. This code expands to 1 pixel per byte without changing the
-values of the pixels:
-
- if (bit_depth < 8)
- png_set_packing(png_ptr);
-
-PNG files have possible bit depths of 1, 2, 4, 8, and 16. All pixels
-stored in a PNG image have been "scaled" or "shifted" up to the next
-higher possible bit depth (e.g. from 5 bits/sample in the range [0,31]
-to 8 bits/sample in the range [0, 255]). However, it is also possible
-to convert the PNG pixel data back to the original bit depth of the
-image. This call reduces the pixels back down to the original bit depth:
-
- png_color_8p sig_bit;
-
- if (png_get_sBIT(png_ptr, info_ptr, &sig_bit))
- png_set_shift(png_ptr, sig_bit);
-
-PNG files store 3-color pixels in red, green, blue order. This code
-changes the storage of the pixels to blue, green, red:
-
- if (color_type == PNG_COLOR_TYPE_RGB ||
- color_type == PNG_COLOR_TYPE_RGB_ALPHA)
- png_set_bgr(png_ptr);
-
-PNG files store RGB pixels packed into 3 or 6 bytes. This code expands them
-into 4 or 8 bytes for windowing systems that need them in this format:
-
- if (color_type == PNG_COLOR_TYPE_RGB)
- png_set_filler(png_ptr, filler, PNG_FILLER_BEFORE);
-
-where "filler" is the 8 or 16-bit number to fill with, and the location is
-either PNG_FILLER_BEFORE or PNG_FILLER_AFTER, depending upon whether
-you want the filler before the RGB or after. This transformation
-does not affect images that already have full alpha channels. To add an
-opaque alpha channel, use filler=0xff or 0xffff and PNG_FILLER_AFTER which
-will generate RGBA pixels.
-
-Note that png_set_filler() does not change the color type. If you want
-to do that, you can add a true alpha channel with
-
- if (color_type == PNG_COLOR_TYPE_RGB ||
- color_type == PNG_COLOR_TYPE_GRAY)
- png_set_add_alpha(png_ptr, filler, PNG_FILLER_AFTER);
-
-where "filler" contains the alpha value to assign to each pixel.
-This function was added in libpng-1.2.7.
-
-If you are reading an image with an alpha channel, and you need the
-data as ARGB instead of the normal PNG format RGBA:
-
- if (color_type == PNG_COLOR_TYPE_RGB_ALPHA)
- png_set_swap_alpha(png_ptr);
-
-For some uses, you may want a grayscale image to be represented as
-RGB. This code will do that conversion:
-
- if (color_type == PNG_COLOR_TYPE_GRAY ||
- color_type == PNG_COLOR_TYPE_GRAY_ALPHA)
- png_set_gray_to_rgb(png_ptr);
-
-Conversely, you can convert an RGB or RGBA image to grayscale or grayscale
-with alpha.
-
- if (color_type == PNG_COLOR_TYPE_RGB ||
- color_type == PNG_COLOR_TYPE_RGB_ALPHA)
- png_set_rgb_to_gray_fixed(png_ptr, error_action,
- int red_weight, int green_weight);
-
- error_action = 1: silently do the conversion
- error_action = 2: issue a warning if the original
- image has any pixel where
- red != green or red != blue
- error_action = 3: issue an error and abort the
- conversion if the original
- image has any pixel where
- red != green or red != blue
-
- red_weight: weight of red component times 100000
- green_weight: weight of green component times 100000
- If either weight is negative, default
- weights (21268, 71514) are used.
-
-If you have set error_action = 1 or 2, you can
-later check whether the image really was gray, after processing
-the image rows, with the png_get_rgb_to_gray_status(png_ptr) function.
-It will return a png_byte that is zero if the image was gray or
-1 if there were any non-gray pixels. bKGD and sBIT data
-will be silently converted to grayscale, using the green channel
-data, regardless of the error_action setting.
-
-With red_weight+green_weight<=100000,
-the normalized graylevel is computed:
-
- int rw = red_weight * 65536;
- int gw = green_weight * 65536;
- int bw = 65536 - (rw + gw);
- gray = (rw*red + gw*green + bw*blue)/65536;

-
- Y = 0.212671 * R + 0.715160 * G + 0.072169 * B
-
-Libpng approximates this with
-
- Y = 0.21268 * R + 0.7151 * G + 0.07217 * B
-
-which can be expressed with integers as
-
- Y = (6969 * R + 23434 * G + 2365 * B)/32768
-
-The calculation is done in a linear colorspace, if the image gamma
-is known.
-
-If you have a grayscale and you are using png_set_expand_depth(),
-png_set_expand(), or png_set_gray_to_rgb to change to truecolor or to
-a higher bit-depth, you must either supply the background color as a gray
-value at the original file bit-depth (need_expand = 1) or else supply the
-background color as an RGB triplet at the final, expanded bit depth
-(need_expand = 0). Similarly, if you are reading a paletted image, you
-must either supply the background color as a palette index (need_expand = 1)
-or as an RGB triplet that may or may not be in the palette (need_expand = 0).
-

- if (png_get_bKGD(png_ptr, info_ptr, &image_background))
- png_set_background(png_ptr, image_background,
- PNG_BACKGROUND_GAMMA_FILE, 1, 1.0);
- else
- png_set_background(png_ptr, &my_background,
- PNG_BACKGROUND_GAMMA_SCREEN, 0, 1.0);
-
-The png_set_background() function tells libpng to composite images
-with alpha or simple transparency against the supplied background
-color. If the PNG file contains a bKGD chunk (PNG_INFO_bKGD valid),
-you may use this color, or supply another color more suitable for
-the current display (e.g., the background color from a web page). You
-need to tell libpng whether the color is in the gamma space of the
-display (PNG_BACKGROUND_GAMMA_SCREEN for colors you supply), the file
-(PNG_BACKGROUND_GAMMA_FILE for colors from the bKGD chunk), or one
-that is neither of these gammas (PNG_BACKGROUND_GAMMA_UNIQUE - I don't
-know why anyone would use this, but it's here).
-
-To properly display PNG images on any kind of system, the application needs
-to know what the display gamma is. Ideally, the user will know this, and
-the application will allow them to set it. One method of allowing the user
-to set the display gamma separately for each system is to check for a
-SCREEN_GAMMA or DISPLAY_GAMMA environment variable, which will hopefully be
-correctly set.
-
-Note that display_gamma is the overall gamma correction required to produce
-pleasing results, which depends on the lighting conditions in the surrounding
-environment. In a dim or brightly lit room, no compensation other than
-the physical gamma exponent of the monitor is needed, while in a dark room
-a slightly smaller exponent is better.

- gamma value */)

- screen_gamma = 2.2; /* A good guess for a
- PC monitor in a bright office or a dim room */
- screen_gamma = 2.0; /* A good guess for a
- PC monitor in a dark room */
- screen_gamma = 1.7 or 1.0; /* A good
- guess for Mac systems */
- }
-
-The png_set_gamma() function handles gamma transformations of the data.
-Pass both the file gamma and the current screen_gamma. If the file does
-not have a gamma value, you can pass one anyway if you have an idea what
-it is (usually 0.45455 is a good guess for GIF images on PCs). Note
-that file gammas are inverted from screen gammas. See the discussions
-on gamma in the PNG specification for an excellent description of what
-gamma is, and why all applications should support it. It is strongly
-recommended that PNG viewers support gamma correction.
-
- if (png_get_gAMA(png_ptr, info_ptr, &gamma))
- png_set_gamma(png_ptr, screen_gamma, gamma);
- else
- png_set_gamma(png_ptr, screen_gamma, 0.45455);
-
-If you need to reduce an RGB file to a paletted file, or if a paletted
-file has more entries then will fit on your screen, png_set_quantize()
-will do that. Note that this is a simple match dither that merely
-finds the closest color available. This should work fairly well with
-optimized palettes, and fairly badly with linear color cubes. If you
-pass a palette that is larger then maximum_colors, the file will
-reduce the number of colors in the palette so it will fit into
-maximum_colors. If there is a histogram, it will use it to make
-more intelligent choices when reducing the palette. If there is no
-histogram, it may not do as good a job.
-
- if (color_type & PNG_COLOR_MASK_COLOR)
- {
- if (png_get_valid(png_ptr, info_ptr,
- PNG_INFO_PLTE))
- {
- png_uint_16p histogram = NULL;
- png_get_hIST(png_ptr, info_ptr,
- &histogram);
- png_set_quantize(png_ptr, palette, num_palette,
- max_screen_colors, histogram, 1);
- }
- else
- {
- png_color std_color_cube[MAX_SCREEN_COLORS] =
- { ... colors ... };
-
- png_set_quantize(png_ptr, std_color_cube,
- MAX_SCREEN_COLORS, MAX_SCREEN_COLORS,
- NULL,0);
- }
- }
-
-PNG files describe monochrome as black being zero and white being one.
-The following code will reverse this (make black be one and white be
-zero):
-
- if (bit_depth == 1 && color_type == PNG_COLOR_TYPE_GRAY)
- png_set_invert_mono(png_ptr);
-
-This function can also be used to invert grayscale and gray-alpha images:
-
- if (color_type == PNG_COLOR_TYPE_GRAY ||
- color_type == PNG_COLOR_TYPE_GRAY_ALPHA)
- png_set_invert_mono(png_ptr);
-
-PNG files store 16 bit pixels in network byte order (big-endian,
-ie. most significant bits first). This code changes the storage to the
-other way (little-endian, i.e. least significant bits first, the
-way PCs store them):
-
- if (bit_depth == 16)
- png_set_swap(png_ptr);
-
-If you are using packed-pixel images (1, 2, or 4 bits/pixel), and you
-need to change the order the pixels are packed into bytes, you can use:
-
- if (bit_depth < 8)
- png_set_packswap(png_ptr);
-
-Finally, you can write your own transformation function if none of
-the existing ones meets your needs. This is done by setting a callback
-with
-
- png_set_read_user_transform_fn(png_ptr,
- read_transform_fn);
-
-You must supply the function
-
- void read_transform_fn(png_structp png_ptr, png_row_infop
- row_info, png_bytep data)
-
-See pngtest.c for a working example. Your function will be called
-after all of the other transformations have been processed.
-
-You can also set up a pointer to a user structure for use by your
-callback function, and you can inform libpng that your transform
-function will change the number of channels or bit depth with the
-function
-
- png_set_user_transform_info(png_ptr, user_ptr,
- user_depth, user_channels);
-
-The user's application, not libpng, is responsible for allocating and
-freeing any memory required for the user structure.
-
-You can retrieve the pointer via the function
-png_get_user_transform_ptr(). For example:
-
- voidp read_user_transform_ptr =
- png_get_user_transform_ptr(png_ptr);
-
-The last thing to handle is interlacing; this is covered in detail below,
-but you must call the function here if you want libpng to handle expansion
-of the interlaced image.
-
- number_of_passes = png_set_interlace_handling(png_ptr);
-
-After setting the transformations, libpng can update your png_info
-structure to reflect any transformations you've requested with this
-call. This is most useful to update the info structure's rowbytes
-field so you can use it to allocate your image memory. This function
-will also update your palette with the correct screen_gamma and
-background if these have been given with the calls above.
-
- png_read_update_info(png_ptr, info_ptr);
-
-After you call png_read_update_info(), you can allocate any
-memory you need to hold the image. The row data is simply
-raw byte data for all forms of images. As the actual allocation
-varies among applications, no example will be given. If you
-are allocating one large chunk, you will need to build an
-array of pointers to each row, as it will be needed for some
-of the functions below.
-
-Reading image data
-
-After you've allocated memory, you can read the image data.
-The simplest way to do this is in one function call. If you are
-allocating enough memory to hold the whole image, you can just
-call png_read_image() and libpng will read in all the image data
-and put it in the memory area supplied. You will need to pass in
-an array of pointers to each row.
-
-This function automatically handles interlacing, so you don't need
-to call png_set_interlace_handling() or call this function multiple
-times, or any of that other stuff necessary with png_read_rows().
-
- png_read_image(png_ptr, row_pointers);
-
-where row_pointers is:
-
- png_bytep row_pointers[height];
-
-You can point to void or char or whatever you use for pixels.
-
-If you don't want to read in the whole image at once, you can
-use png_read_rows() instead. If there is no interlacing (check
-interlace_type == PNG_INTERLACE_NONE), this is simple:
-
- png_read_rows(png_ptr, row_pointers, NULL,
- number_of_rows);
-
-where row_pointers is the same as in the png_read_image() call.
-
-If you are doing this just one row at a time, you can do this with
-a single row_pointer instead of an array of row_pointers:
-
- png_bytep row_pointer = row;
- png_read_row(png_ptr, row_pointer, NULL);
-
-If the file is interlaced (interlace_type != 0 in the IHDR chunk), things
-get somewhat harder. The only current (PNG Specification version 1.2)
-interlacing type for PNG is (interlace_type == PNG_INTERLACE_ADAM7)
-is a somewhat complicated 2D interlace scheme, known as Adam7, that
-breaks down an image into seven smaller images of varying size, based
-on an 8x8 grid.
-
-libpng can fill out those images or it can give them to you "as is".
-If you want them filled out, there are two ways to do that. The one
-mentioned in the PNG specification is to expand each pixel to cover
-those pixels that have not been read yet (the "rectangle" method).
-This results in a blocky image for the first pass, which gradually
-smooths out as more pixels are read. The other method is the "sparkle"
-method, where pixels are drawn only in their final locations, with the
-rest of the image remaining whatever colors they were initialized to
-before the start of the read. The first method usually looks better,
-but tends to be slower, as there are more pixels to put in the rows.
-
-If you don't want libpng to handle the interlacing details, just call
-png_read_rows() seven times to read in all seven images. Each of the
-images is a valid image by itself, or they can all be combined on an
-8x8 grid to form a single image (although if you intend to combine them
-you would be far better off using the libpng interlace handling).
-
-The first pass will return an image 1/8 as wide as the entire image
-(every 8th column starting in column 0) and 1/8 as high as the original
-(every 8th row starting in row 0), the second will be 1/8 as wide
-(starting in column 4) and 1/8 as high (also starting in row 0). The
-third pass will be 1/4 as wide (every 4th pixel starting in column 0) and
-1/8 as high (every 8th row starting in row 4), and the fourth pass will
-be 1/4 as wide and 1/4 as high (every 4th column starting in column 2,
-and every 4th row starting in row 0). The fifth pass will return an
-image 1/2 as wide, and 1/4 as high (starting at column 0 and row 2),
-while the sixth pass will be 1/2 as wide and 1/2 as high as the original
-(starting in column 1 and row 0). The seventh and final pass will be as
-wide as the original, and 1/2 as high, containing all of the odd
-numbered scanlines. Phew!
-
-If you want libpng to expand the images, call this before calling
-png_start_read_image() or png_read_update_info():
-
- if (interlace_type == PNG_INTERLACE_ADAM7)
- number_of_passes
- = png_set_interlace_handling(png_ptr);
-
-This will return the number of passes needed. Currently, this
-is seven, but may change if another interlace type is added.
-This function can be called even if the file is not interlaced,
-where it will return one pass.
-
-If you are not going to display the image after each pass, but are
-going to wait until the entire image is read in, use the sparkle
-effect. This effect is faster and the end result of either method
-is exactly the same. If you are planning on displaying the image
-after each pass, the "rectangle" effect is generally considered the
-better looking one.
-
-If you only want the "sparkle" effect, just call png_read_rows() as
-normal, with the third parameter NULL. Make sure you make pass over
-the image number_of_passes times, and you don't change the data in the
-rows between calls. You can change the locations of the data, just
-not the data. Each pass only writes the pixels appropriate for that
-pass, and assumes the data from previous passes is still valid.
-
- png_read_rows(png_ptr, row_pointers, NULL,
- number_of_rows);
-
-If you only want the first effect (the rectangles), do the same as
-before except pass the row buffer in the third parameter, and leave
-the second parameter NULL.
-
- png_read_rows(png_ptr, NULL, row_pointers,
- number_of_rows);
-
-Finishing a sequential read
-
-After you are finished reading the image through the
-low-level interface, you can finish reading the file. If you are
-interested in comments or time, which may be stored either before or
-after the image data, you should pass the separate png_info struct if
-you want to keep the comments from before and after the image
-separate. If you are not interested, you can pass NULL.
-
- png_read_end(png_ptr, end_info);
-
-When you are done, you can free all memory allocated by libpng like this:
-
- png_destroy_read_struct(&png_ptr, &info_ptr,
- &end_info);
-
-It is also possible to individually free the info_ptr members that
-point to libpng-allocated storage with the following function:
-
- png_free_data(png_ptr, info_ptr, mask, seq)
- mask - identifies data to be freed, a mask
- containing the bitwise OR of one or
- more of
- PNG_FREE_PLTE, PNG_FREE_TRNS,
- PNG_FREE_HIST, PNG_FREE_ICCP,
- PNG_FREE_PCAL, PNG_FREE_ROWS,
- PNG_FREE_SCAL, PNG_FREE_SPLT,
- PNG_FREE_TEXT, PNG_FREE_UNKN,
- or simply PNG_FREE_ALL
- seq - sequence number of item to be freed
- (-1 for all items)
-
-This function may be safely called when the relevant storage has
-already been freed, or has not yet been allocated, or was allocated
-by the user and not by libpng, and will in those cases do nothing.
-The "seq" parameter is ignored if only one item of the selected data
-type, such as PLTE, is allowed. If "seq" is not -1, and multiple items
-are allowed for the data type identified in the mask, such as text or
-sPLT, only the n'th item in the structure is freed, where n is "seq".
-
-The default behavior is only to free data that was allocated internally
-by libpng. This can be changed, so that libpng will not free the data,
-or so that it will free data that was allocated by the user with png_malloc()
-or png_zalloc() and passed in via a png_set_*() function, with
-
- png_data_freer(png_ptr, info_ptr, freer, mask)
- mask - which data elements are affected
- same choices as in png_free_data()
- freer - one of
- PNG_DESTROY_WILL_FREE_DATA
- PNG_SET_WILL_FREE_DATA
- PNG_USER_WILL_FREE_DATA
-
-This function only affects data that has already been allocated.
-You can call this function after reading the PNG data but before calling
-any png_set_*() functions, to control whether the user or the png_set_*()
-function is responsible for freeing any existing data that might be present,
-and again after the png_set_*() functions to control whether the user
-or png_destroy_*() is supposed to free the data. When the user assumes
-responsibility for libpng-allocated data, the application must use
-png_free() to free it, and when the user transfers responsibility to libpng
-for data that the user has allocated, the user must have used png_malloc()
-or png_zalloc() to allocate it.
-
-If you allocated your row_pointers in a single block, as suggested above in
-the description of the high level read interface, you must not transfer
-responsibility for freeing it to the png_set_rows or png_read_destroy function,
-because they would also try to free the individual row_pointers[i].
-
-If you allocated text_ptr.text, text_ptr.lang, and text_ptr.translated_keyword
-separately, do not transfer responsibility for freeing text_ptr to libpng,
-because when libpng fills a png_text structure it combines these members with
-the key member, and png_free_data() will free only text_ptr.key. Similarly,
-if you transfer responsibility for free'ing text_ptr from libpng to your
-application, your application must not separately free those members.
-
-The png_free_data() function will turn off the "valid" flag for anything
-it frees. If you need to turn the flag off for a chunk that was freed by
-your application instead of by libpng, you can use
-
- png_set_invalid(png_ptr, info_ptr, mask);
- mask - identifies the chunks to be made invalid,
- containing the bitwise OR of one or
- more of
- PNG_INFO_gAMA, PNG_INFO_sBIT,
- PNG_INFO_cHRM, PNG_INFO_PLTE,
- PNG_INFO_tRNS, PNG_INFO_bKGD,
- PNG_INFO_hIST, PNG_INFO_pHYs,
- PNG_INFO_oFFs, PNG_INFO_tIME,
- PNG_INFO_pCAL, PNG_INFO_sRGB,
- PNG_INFO_iCCP, PNG_INFO_sPLT,
- PNG_INFO_sCAL, PNG_INFO_IDAT
-
-For a more compact example of reading a PNG image, see the file example.c.
-
-Reading PNG files progressively
-
-The progressive reader is slightly different then the non-progressive
-reader. Instead of calling png_read_info(), png_read_rows(), and
-png_read_end(), you make one call to png_process_data(), which calls
-callbacks when it has the info, a row, or the end of the image. You
-set up these callbacks with png_set_progressive_read_fn(). You don't
-have to worry about the input/output functions of libpng, as you are
-giving the library the data directly in png_process_data(). I will
-assume that you have read the section on reading PNG files above,
-so I will only highlight the differences (although I will show
-all of the code).

-
-
-
-IV. Writing
-
-Much of this is very similar to reading. However, everything of
-importance is repeated here, so you won't have to constantly look
-back up in the reading section to understand writing.
-
-Setup
-
-You will want to do the I/O initialization before you get into libpng,
-so if it doesn't work, you don't have anything to undo. If you are not
-using the standard I/O functions, you will need to replace them with
-custom writing functions. See the discussion under Customizing libpng.
-
- FILE *fp = fopen(file_name, "wb");
- if (!fp)
- {
- return (ERROR);
- }
-
-Next, png_struct and png_info need to be allocated and initialized.
-As these can be both relatively large, you may not want to store these
-on the stack, unless you have stack space to spare. Of course, you
-will want to check if they return NULL. If you are also reading,
-you won't want to name your read structure and your write structure
-both "png_ptr"; you can call them anything you like, such as
-"read_ptr" and "write_ptr". Look at pngtest.c, for example.
-
- png_structp png_ptr = png_create_write_struct
- (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
- user_error_fn, user_warning_fn);
- if (!png_ptr)
- return (ERROR);
-
- png_infop info_ptr = png_create_info_struct(png_ptr);
- if (!info_ptr)
- {
- png_destroy_write_struct(&png_ptr,
- (png_infopp)NULL);
- return (ERROR);
- }
-
-If you want to use your own memory allocation routines,
-define PNG_USER_MEM_SUPPORTED and use
-png_create_write_struct_2() instead of png_create_write_struct():
-
- png_structp png_ptr = png_create_write_struct_2
- (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
- user_error_fn, user_warning_fn, (png_voidp)
- user_mem_ptr, user_malloc_fn, user_free_fn);
-
-After you have these structures, you will need to set up the
-error handling. When libpng encounters an error, it expects to
-longjmp() back to your routine. Therefore, you will need to call
-setjmp() and pass the png_jmpbuf(png_ptr). If you
-write the file from different routines, you will need to update
-the png_jmpbuf(png_ptr) every time you enter a new routine that will
-call a png_*() function. See your documentation of setjmp/longjmp
-for your compiler for more information on setjmp/longjmp. See
-the discussion on libpng error handling in the Customizing Libpng
-section below for more information on the libpng error handling.
-
- if (setjmp(png_jmpbuf(png_ptr)))
- {
- png_destroy_write_struct(&png_ptr, &info_ptr);
- fclose(fp);
- return (ERROR);
- }
- ...
- return;
-
-If you would rather avoid the complexity of setjmp/longjmp issues,
-you can compile libpng with PNG_NO_SETJMP, in which case
-errors will result in a call to PNG_ABORT() which defaults to abort().
-
-You can #define PNG_ABORT() to a function that does something
-more useful than abort(), as long as your function does not
-return.
-
-Now you need to set up the output code. The default for libpng is to
-use the C function fwrite(). If you use this, you will need to pass a
-valid FILE * in the function png_init_io(). Be sure that the file is
-opened in binary mode. Again, if you wish to handle writing data in
-another way, see the discussion on libpng I/O handling in the Customizing
-Libpng section below.
-
- png_init_io(png_ptr, fp);
-
-If you are embedding your PNG into a datastream such as MNG, and don't
-want libpng to write the 8-byte signature, or if you have already
-written the signature in your application, use
-
- png_set_sig_bytes(png_ptr, 8);
-
-to inform libpng that it should not write a signature.
-
-Write callbacks
-
-At this point, you can set up a callback function that will be
-called after each row has been written, which you can use to control
-a progress meter or the like. It's demonstrated in pngtest.c.
-You must supply a function
-
- void write_row_callback(png_structp png_ptr, png_uint_32 row,
- int pass);
- {
- /* put your code here */
- }
-
-(You can give it another name that you like instead of "write_row_callback")
-
-To inform libpng about your function, use
-
- png_set_write_status_fn(png_ptr, write_row_callback);
-
-You now have the option of modifying how the compression library will
-run. The following functions are mainly for testing, but may be useful
-in some cases, like if you need to write PNG files extremely fast and
-are willing to give up some compression, or if you want to get the
-maximum possible compression at the expense of slower writing. If you
-have no special needs in this area, let the library do what it wants by
-not calling this function at all, as it has been tuned to deliver a good
-speed/compression ratio. The second parameter to png_set_filter() is
-the filter method, for which the only valid values are 0 (as of the
-July 1999 PNG specification, version 1.2) or 64 (if you are writing
-a PNG datastream that is to be embedded in a MNG datastream). The third
-parameter is a flag that indicates which filter type(s) are to be tested
-for each scanline. See the PNG specification for details on the specific
-filter types.

- specific filters. You can use either a single

- PNG_FILTER_PAETH | PNG_FILTER_VALUE_PAETH|
- PNG_ALL_FILTERS);
-
-If an application
-wants to start and stop using particular filters during compression,
-it should start out with all of the filters (to ensure that the previous
-row of pixels will be stored in case it's needed later), and then add
-and remove them after the start of compression.
-
-If you are writing a PNG datastream that is to be embedded in a MNG
-datastream, the second parameter can be either 0 or 64.
-
-The png_set_compression_*() functions interface to the zlib compression
-library, and should mostly be ignored unless you really know what you are
-doing. The only generally useful call is png_set_compression_level()
-which changes how much time zlib spends on trying to compress the image
-data. See the Compression Library (zlib.h and algorithm.txt, distributed
-with zlib) for details on the compression levels.

-Setting the contents of info for output
-
-You now need to fill in the png_info structure with all the data you
-wish to write before the actual image. Note that the only thing you
-are allowed to write after the image is the text chunks and the time
-chunk (as of PNG Specification 1.2, anyway). See png_write_end() and
-the latest PNG specification for more information on that. If you
-wish to write them before the image, fill them in now, and flag that
-data as being valid. If you want to wait until after the data, don't
-fill them until png_write_end(). For all the fields in png_info and
-their data types, see png.h. For explanations of what the fields
-contain, see the PNG specification.
-
-Some of the more important parts of the png_info are:
-
- png_set_IHDR(png_ptr, info_ptr, width, height,
- bit_depth, color_type, interlace_type,
- compression_type, filter_method)
- width - holds the width of the image
- in pixels (up to 2^31).
- height - holds the height of the image
- in pixels (up to 2^31).
- bit_depth - holds the bit depth of one of the
- image channels.
- (valid values are 1, 2, 4, 8, 16
- and depend also on the
- color_type. See also significant
- bits (sBIT) below).
- color_type - describes which color/alpha
- channels are present.
- PNG_COLOR_TYPE_GRAY
- (bit depths 1, 2, 4, 8, 16)
- PNG_COLOR_TYPE_GRAY_ALPHA
- (bit depths 8, 16)
- PNG_COLOR_TYPE_PALETTE
- (bit depths 1, 2, 4, 8)
- PNG_COLOR_TYPE_RGB
- (bit_depths 8, 16)
- PNG_COLOR_TYPE_RGB_ALPHA
- (bit_depths 8, 16)
-
- PNG_COLOR_MASK_PALETTE
- PNG_COLOR_MASK_COLOR
- PNG_COLOR_MASK_ALPHA
-
- interlace_type - PNG_INTERLACE_NONE or
- PNG_INTERLACE_ADAM7
- compression_type - (must be
- PNG_COMPRESSION_TYPE_DEFAULT)
- filter_method - (must be PNG_FILTER_TYPE_DEFAULT
- or, if you are writing a PNG to
- be embedded in a MNG datastream,
- can also be
- PNG_INTRAPIXEL_DIFFERENCING)
-
-If you call png_set_IHDR(), the call must appear before any of the
-other png_set_*() functions, because they might require access to some of
-the IHDR settings. The remaining png_set_*() functions can be called
-in any order.
-
-If you wish, you can reset the compression_type, interlace_type, or
-filter_method later by calling png_set_IHDR() again; if you do this, the
-width, height, bit_depth, and color_type must be the same in each call.

-
-The "location" member is set automatically according to
-what part of the output file has already been written.
-You can change its value after calling png_set_unknown_chunks()
-as demonstrated in pngtest.c. Within each of the "locations",
-the chunks are sequenced according to their position in the
-structure (that is, the value of "i", which is the order in which
-the chunk was either read from the input file or defined with
-png_set_unknown_chunks).
-
-A quick word about text and num_text. text is an array of png_text
-structures. num_text is the number of valid structures in the array.
-Each png_text structure holds a language code, a keyword, a text value,
-and a compression type.
-
-The compression types have the same valid numbers as the compression
-types of the image data. Currently, the only valid number is zero.
-However, you can store text either compressed or uncompressed, unlike
-images, which always have to be compressed. So if you don't want the
-text compressed, set the compression type to PNG_TEXT_COMPRESSION_NONE.
-Because tEXt and zTXt chunks don't have a language field, if you
-specify PNG_TEXT_COMPRESSION_NONE or PNG_TEXT_COMPRESSION_zTXt
-any language code or translated keyword will not be written out.
-
-Until text gets around 1000 bytes, it is not worth compressing it.
-After the text has been written out to the file, the compression type
-is set to PNG_TEXT_COMPRESSION_NONE_WR or PNG_TEXT_COMPRESSION_zTXt_WR,
-so that it isn't written out again at the end (in case you are calling
-png_write_end() with the same struct.
-
-The keywords that are given in the PNG Specification are:
-
- Title Short (one line) title or
- caption for image
- Author Name of image's creator
- Description Description of image (possibly long)
- Copyright Copyright notice
- Creation Time Time of original image creation
- (usually RFC 1123 format, see below)
- Software Software used to create the image
- Disclaimer Legal disclaimer
- Warning Warning of nature of content
- Source Device used to create the image
- Comment Miscellaneous comment; conversion
- from other image format
-
-The keyword-text pairs work like this. Keywords should be short
-simple descriptions of what the comment is about. Some typical
-keywords are found in the PNG specification, as is some recommendations
-on keywords. You can repeat keywords in a file. You can even write
-some text before the image and some after. For example, you may want
-to put a description of the image before the image, but leave the
-disclaimer until after, so viewers working over modem connections
-don't have to wait for the disclaimer to go over the modem before
-they start seeing the image. Finally, keywords should be full
-words, not abbreviations. Keywords and text are in the ISO 8859-1
-(Latin-1) character set (a superset of regular ASCII) and can not
-contain NUL characters, and should not contain control or other
-unprintable characters. To make the comments widely readable, stick
-with basic ASCII, and avoid machine specific character set extensions
-like the IBM-PC character set. The keyword must be present, but
-you can leave off the text string on non-compressed pairs.
-Compressed pairs must have a text string, as only the text string
-is compressed anyway, so the compression would be meaningless.
-
-PNG supports modification time via the png_time structure. Two
-conversion routines are provided, png_convert_from_time_t() for
-time_t and png_convert_from_struct_tm() for struct tm. The
-time_t routine uses gmtime(). You don't have to use either of
-these, but if you wish to fill in the png_time structure directly,
-you should provide the time in universal time (GMT) if possible
-instead of your local time. Note that the year number is the full
-year (e.g. 1998, rather than 98 - PNG is year 2000 compliant!), and
-that months start with 1.
-
-If you want to store the time of the original image creation, you should
-use a plain tEXt chunk with the "Creation Time" keyword. This is
-necessary because the "creation time" of a PNG image is somewhat vague,
-depending on whether you mean the PNG file, the time the image was
-created in a non-PNG format, a still photo from which the image was
-scanned, or possibly the subject matter itself. In order to facilitate
-machine-readable dates, it is recommended that the "Creation Time"
-tEXt chunk use RFC 1123 format dates (e.g. "22 May 1997 18:07:10 GMT"),
-although this isn't a requirement. Unlike the tIME chunk, the
-"Creation Time" tEXt chunk is not expected to be automatically changed
-by the software. To facilitate the use of RFC 1123 dates, a function
-png_convert_to_rfc1123(png_timep) is provided to convert from PNG
-time to an RFC 1123 format string.
-
-Writing unknown chunks
-
-You can use the png_set_unknown_chunks function to queue up chunks
-for writing. You give it a chunk name, raw data, and a size; that's
-all there is to it. The chunks will be written by the next following
-png_write_info_before_PLTE, png_write_info, or png_write_end function.
-Any chunks previously read into the info structure's unknown-chunk
-list will also be written out in a sequence that satisfies the PNG
-specification's ordering rules.
-
-The high-level write interface
-
-At this point there are two ways to proceed; through the high-level
-write interface, or through a sequence of low-level write operations.
-You can use the high-level interface if your image data is present
-in the info structure. All defined output
-transformations are permitted, enabled by the following masks.
-
- PNG_TRANSFORM_IDENTITY No transformation
- PNG_TRANSFORM_PACKING Pack 1, 2 and 4-bit samples
- PNG_TRANSFORM_PACKSWAP Change order of packed
- pixels to LSB first
- PNG_TRANSFORM_INVERT_MONO Invert monochrome images
- PNG_TRANSFORM_SHIFT Normalize pixels to the
- sBIT depth
- PNG_TRANSFORM_BGR Flip RGB to BGR, RGBA
- to BGRA
- PNG_TRANSFORM_SWAP_ALPHA Flip RGBA to ARGB or GA
- to AG
- PNG_TRANSFORM_INVERT_ALPHA Change alpha from opacity
- to transparency
- PNG_TRANSFORM_SWAP_ENDIAN Byte-swap 16-bit samples
- PNG_TRANSFORM_STRIP_FILLER Strip out filler
- bytes (deprecated).
- PNG_TRANSFORM_STRIP_FILLER_BEFORE Strip out leading
- filler bytes
- PNG_TRANSFORM_STRIP_FILLER_AFTER Strip out trailing
- filler bytes
-
-If you have valid image data in the info structure (you can use
-png_set_rows() to put image data in the info structure), simply do this:
-
- png_write_png(png_ptr, info_ptr, png_transforms, NULL)
-
-where png_transforms is an integer containing the bitwise OR of some set of
-transformation flags. This call is equivalent to png_write_info(),
-followed the set of transformations indicated by the transform mask,
-then png_write_image(), and finally png_write_end().
-
-(The final parameter of this call is not yet used. Someday it might point
-to transformation parameters required by some future output transform.)
-
-You must use png_transforms and not call any png_set_transform() functions
-when you use png_write_png().
-
-The low-level write interface
-
-If you are going the low-level route instead, you are now ready to
-write all the file information up to the actual image data. You do
-this with a call to png_write_info().
-
- png_write_info(png_ptr, info_ptr);
-
-Note that there is one transformation you may need to do before
-png_write_info(). In PNG files, the alpha channel in an image is the
-level of opacity. If your data is supplied as a level of transparency,
-you can invert the alpha channel before you write it, so that 0 is
-fully transparent and 255 (in 8-bit or paletted images) or 65535
-(in 16-bit images) is fully opaque, with
-
- png_set_invert_alpha(png_ptr);
-
-This must appear before png_write_info() instead of later with the
-other transformations because in the case of paletted images the tRNS
-chunk data has to be inverted before the tRNS chunk is written. If
-your image is not a paletted image, the tRNS data (which in such cases
-represents a single color to be rendered as transparent) won't need to
-be changed, and you can safely do this transformation after your
-png_write_info() call.
-
-If you need to write a private chunk that you want to appear before
-the PLTE chunk when PLTE is present, you can write the PNG info in
-two steps, and insert code to write your own chunk between them:
-
- png_write_info_before_PLTE(png_ptr, info_ptr);
- png_set_unknown_chunks(png_ptr, info_ptr, ...);
- png_write_info(png_ptr, info_ptr);
-
-After you've written the file information, you can set up the library
-to handle any special transformations of the image data. The various
-ways to transform the data will be described in the order that they
-should occur. This is important, as some of these change the color
-type and/or bit depth of the data, and some others only work on
-certain color types and bit depths. Even though each transformation
-checks to see if it has data that it can do something with, you should
-make sure to only enable a transformation if it will be valid for the
-data. For example, don't swap red and blue on grayscale data.
-
-PNG files store RGB pixels packed into 3 or 6 bytes. This code tells
-the library to strip input data that has 4 or 8 bytes per pixel down
-to 3 or 6 bytes (or strip 2 or 4-byte grayscale+filler data to 1 or 2
-bytes per pixel).
-
- png_set_filler(png_ptr, 0, PNG_FILLER_BEFORE);
-
-where the 0 is unused, and the location is either PNG_FILLER_BEFORE or
-PNG_FILLER_AFTER, depending upon whether the filler byte in the pixel
-is stored XRGB or RGBX.
-
-PNG files pack pixels of bit depths 1, 2, and 4 into bytes as small as
-they can, resulting in, for example, 8 pixels per byte for 1 bit files.
-If the data is supplied at 1 pixel per byte, use this code, which will
-correctly pack the pixels into a single byte:
-
- png_set_packing(png_ptr);
-
-PNG files reduce possible bit depths to 1, 2, 4, 8, and 16. If your
-data is of another bit depth, you can write an sBIT chunk into the
-file so that decoders can recover the original data if desired.
-
- /* Set the true bit depth of the image data */
- if (color_type & PNG_COLOR_MASK_COLOR)
- {
- sig_bit.red = true_bit_depth;
- sig_bit.green = true_bit_depth;
- sig_bit.blue = true_bit_depth;
- }
- else
- {
- sig_bit.gray = true_bit_depth;
- }
- if (color_type & PNG_COLOR_MASK_ALPHA)
- {
- sig_bit.alpha = true_bit_depth;
- }
-
- png_set_sBIT(png_ptr, info_ptr, &sig_bit);
-
-If the data is stored in the row buffer in a bit depth other than
-one supported by PNG (e.g. 3 bit data in the range 0-7 for a 4-bit PNG),
-this will scale the values to appear to be the correct bit depth as
-is required by PNG.
-
- png_set_shift(png_ptr, &sig_bit);
-
-PNG files store 16 bit pixels in network byte order (big-endian,
-ie. most significant bits first). This code would be used if they are
-supplied the other way (little-endian, i.e. least significant bits
-first, the way PCs store them):
-
- if (bit_depth > 8)
- png_set_swap(png_ptr);
-
-If you are using packed-pixel images (1, 2, or 4 bits/pixel), and you
-need to change the order the pixels are packed into bytes, you can use:
-
- if (bit_depth < 8)
- png_set_packswap(png_ptr);
-
-PNG files store 3 color pixels in red, green, blue order. This code
-would be used if they are supplied as blue, green, red:
-
- png_set_bgr(png_ptr);
-
-PNG files describe monochrome as black being zero and white being
-one. This code would be used if the pixels are supplied with this reversed
-(black being one and white being zero):
-
- png_set_invert_mono(png_ptr);
-
-Finally, you can write your own transformation function if none of
-the existing ones meets your needs. This is done by setting a callback
-with
-
- png_set_write_user_transform_fn(png_ptr,
- write_transform_fn);
-
-You must supply the function
-
- void write_transform_fn(png_structp png_ptr, png_row_infop
- row_info, png_bytep data)
-
-See pngtest.c for a working example. Your function will be called
-before any of the other transformations are processed.
-
-You can also set up a pointer to a user structure for use by your
-callback function.
-
- png_set_user_transform_info(png_ptr, user_ptr, 0, 0);
-
-The user_channels and user_depth parameters of this function are ignored
-when writing; you can set them to zero as shown.
-
-You can retrieve the pointer via the function png_get_user_transform_ptr().
-For example:
-
- voidp write_user_transform_ptr =
- png_get_user_transform_ptr(png_ptr);
-
-It is possible to have libpng flush any pending output, either manually,
-or automatically after a certain number of lines have been written. To
-flush the output stream a single time call:
-
- png_write_flush(png_ptr);
-
-and to have libpng flush the output stream periodically after a certain
-number of scanlines have been written, call:
-
- png_set_flush(png_ptr, nrows);
-
-Note that the distance between rows is from the last time png_write_flush()
-was called, or the first row of the image if it has never been called.
-So if you write 50 lines, and then png_set_flush 25, it will flush the
-output on the next scanline, and every 25 lines thereafter, unless
-png_write_flush() is called before 25 more lines have been written.
-If nrows is too small (less than about 10 lines for a 640 pixel wide
-RGB image) the image compression may decrease noticeably (although this
-may be acceptable for real-time applications). Infrequent flushing will
-only degrade the compression performance by a few percent over images
-that do not use flushing.
-
-Writing the image data
-
-That's it for the transformations. Now you can write the image data.
-The simplest way to do this is in one function call. If you have the
-whole image in memory, you can just call png_write_image() and libpng
-will write the image. You will need to pass in an array of pointers to
-each row. This function automatically handles interlacing, so you don't
-need to call png_set_interlace_handling() or call this function multiple
-times, or any of that other stuff necessary with png_write_rows().
-
- png_write_image(png_ptr, row_pointers);
-
-where row_pointers is:
-
- png_byte *row_pointers[height];
-
-You can point to void or char or whatever you use for pixels.
-
-If you don't want to write the whole image at once, you can
-use png_write_rows() instead. If the file is not interlaced,
-this is simple:
-
- png_write_rows(png_ptr, row_pointers,
- number_of_rows);
-
-row_pointers is the same as in the png_write_image() call.
-
-If you are just writing one row at a time, you can do this with
-a single row_pointer instead of an array of row_pointers:
-
- png_bytep row_pointer = row;
-
- png_write_row(png_ptr, row_pointer);
-
-When the file is interlaced, things can get a good deal more complicated.
-The only currently (as of the PNG Specification version 1.2, dated July
-1999) defined interlacing scheme for PNG files is the "Adam7" interlace
-scheme, that breaks down an image into seven smaller images of varying
-size. libpng will build these images for you, or you can do them
-yourself. If you want to build them yourself, see the PNG specification
-for details of which pixels to write when.
-
-If you don't want libpng to handle the interlacing details, just
-use png_set_interlace_handling() and call png_write_rows() the
-correct number of times to write all seven sub-images.
-
-If you want libpng to build the sub-images, call this before you start
-writing any rows:
-
- number_of_passes =
- png_set_interlace_handling(png_ptr);
-
-This will return the number of passes needed. Currently, this is seven,
-but may change if another interlace type is added.
-
-Then write the complete image number_of_passes times.
-
- png_write_rows(png_ptr, row_pointers,
- number_of_rows);
-
-As some of these rows are not used, and thus return immediately, you may
-want to read about interlacing in the PNG specification, and only update
-the rows that are actually used.
-
-Finishing a sequential write
-
-After you are finished writing the image, you should finish writing
-the file. If you are interested in writing comments or time, you should
-pass an appropriately filled png_info pointer. If you are not interested,
-you can pass NULL.
-
- png_write_end(png_ptr, info_ptr);
-
-When you are done, you can free all memory used by libpng like this:
-
- png_destroy_write_struct(&png_ptr, &info_ptr);
-
-It is also possible to individually free the info_ptr members that
-point to libpng-allocated storage with the following function:
-
- png_free_data(png_ptr, info_ptr, mask, seq)
- mask - identifies data to be freed, a mask
- containing the bitwise OR of one or
- more of
- PNG_FREE_PLTE, PNG_FREE_TRNS,
- PNG_FREE_HIST, PNG_FREE_ICCP,
- PNG_FREE_PCAL, PNG_FREE_ROWS,
- PNG_FREE_SCAL, PNG_FREE_SPLT,
- PNG_FREE_TEXT, PNG_FREE_UNKN,
- or simply PNG_FREE_ALL
- seq - sequence number of item to be freed
- (-1 for all items)
-
-This function may be safely called when the relevant storage has
-already been freed, or has not yet been allocated, or was allocated
-by the user and not by libpng, and will in those cases do nothing.
-The "seq" parameter is ignored if only one item of the selected data
-type, such as PLTE, is allowed. If "seq" is not -1, and multiple items
-are allowed for the data type identified in the mask, such as text or
-sPLT, only the n'th item in the structure is freed, where n is "seq".
-
-If you allocated data such as a palette that you passed in to libpng
-with png_set_*, you must not free it until just before the call to
-png_destroy_write_struct().
-
-The default behavior is only to free data that was allocated internally
-by libpng. This can be changed, so that libpng will not free the data,
-or so that it will free data that was allocated by the user with png_malloc()
-or png_zalloc() and passed in via a png_set_*() function, with
-
- png_data_freer(png_ptr, info_ptr, freer, mask)
- mask - which data elements are affected
- same choices as in png_free_data()
- freer - one of
- PNG_DESTROY_WILL_FREE_DATA
- PNG_SET_WILL_FREE_DATA
- PNG_USER_WILL_FREE_DATA
-
-For example, to transfer responsibility for some data from a read structure
-to a write structure, you could use
-
- png_data_freer(read_ptr, read_info_ptr,
- PNG_USER_WILL_FREE_DATA,
- PNG_FREE_PLTE|PNG_FREE_tRNS|PNG_FREE_hIST)
- png_data_freer(write_ptr, write_info_ptr,
- PNG_DESTROY_WILL_FREE_DATA,
- PNG_FREE_PLTE|PNG_FREE_tRNS|PNG_FREE_hIST)
-
-thereby briefly reassigning responsibility for freeing to the user but
-immediately afterwards reassigning it once more to the write_destroy
-function. Having done this, it would then be safe to destroy the read
-structure and continue to use the PLTE, tRNS, and hIST data in the write
-structure.
-
-This function only affects data that has already been allocated.
-You can call this function before calling after the png_set_*() functions
-to control whether the user or png_destroy_*() is supposed to free the data.
-When the user assumes responsibility for libpng-allocated data, the
-application must use
-png_free() to free it, and when the user transfers responsibility to libpng
-for data that the user has allocated, the user must have used png_malloc()
-or png_zalloc() to allocate it.
-
-If you allocated text_ptr.text, text_ptr.lang, and text_ptr.translated_keyword
-separately, do not transfer responsibility for freeing text_ptr to libpng,
-because when libpng fills a png_text structure it combines these members with
-the key member, and png_free_data() will free only text_ptr.key. Similarly,
-if you transfer responsibility for free'ing text_ptr from libpng to your
-application, your application must not separately free those members.
-For a more compact example of writing a PNG image, see the file example.c.
-
-V. Modifying/Customizing libpng:
-
-There are two issues here. The first is changing how libpng does
-standard things like memory allocation, input/output, and error handling.
-The second deals with more complicated things like adding new chunks,
-adding new transformations, and generally changing how libpng works.
-Both of those are compile-time issues; that is, they are generally
-determined at the time the code is written, and there is rarely a need
-to provide the user with a means of changing them.
-
-Memory allocation, input/output, and error handling
-
-All of the memory allocation, input/output, and error handling in libpng
-goes through callbacks that are user-settable. The default routines are
-in pngmem.c, pngrio.c, pngwio.c, and pngerror.c, respectively. To change
-these functions, call the appropriate png_set_*_fn() function.
-
-Memory allocation is done through the functions png_malloc(), png_calloc(),
-and png_free(). These currently just call the standard C functions.
-png_calloc() calls png_malloc() and then png_memset() to clear the newly
-allocated memory to zero. If your pointers can't access more then 64K
-at a time, you will want to set MAXSEG_64K in zlib.h. Since it is
-unlikely that the method of handling memory allocation on a platform
-will change between applications, these functions must be modified in
-the library at compile time. If you prefer to use a different method
-of allocating and freeing data, you can use png_create_read_struct_2() or
-png_create_write_struct_2() to register your own functions as described
-above. These functions also provide a void pointer that can be retrieved
-via
-
- mem_ptr=png_get_mem_ptr(png_ptr);
-
-Your replacement memory functions must have prototypes as follows:
-
- png_voidp malloc_fn(png_structp png_ptr,
- png_alloc_size_t size);
- void free_fn(png_structp png_ptr, png_voidp ptr);
-
-Your malloc_fn() must return NULL in case of failure. The png_malloc()
-function will normally call png_error() if it receives a NULL from the
-system memory allocator or from your replacement malloc_fn().
-
-Your free_fn() will never be called with a NULL ptr, since libpng's
-png_free() checks for NULL before calling free_fn().
-
-Input/Output in libpng is done through png_read() and png_write(),
-which currently just call fread() and fwrite(). The FILE * is stored in
-png_struct and is initialized via png_init_io(). If you wish to change
-the method of I/O, the library supplies callbacks that you can set
-through the function png_set_read_fn() and png_set_write_fn() at run
-time, instead of calling the png_init_io() function. These functions
-also provide a void pointer that can be retrieved via the function
-png_get_io_ptr(). For example:
-
- png_set_read_fn(png_structp read_ptr,
- voidp read_io_ptr, png_rw_ptr read_data_fn)
-
- png_set_write_fn(png_structp write_ptr,
- voidp write_io_ptr, png_rw_ptr write_data_fn,
- png_flush_ptr output_flush_fn);
-
- voidp read_io_ptr = png_get_io_ptr(read_ptr);
- voidp write_io_ptr = png_get_io_ptr(write_ptr);
-
-The replacement I/O functions must have prototypes as follows:
-
- void user_read_data(png_structp png_ptr,
- png_bytep data, png_size_t length);
- void user_write_data(png_structp png_ptr,
- png_bytep data, png_size_t length);
- void user_flush_data(png_structp png_ptr);
-
-The user_read_data() function is responsible for detecting and
-handling end-of-data errors.
-
-Supplying NULL for the read, write, or flush functions sets them back
-to using the default C stream functions, which expect the io_ptr to
-point to a standard *FILE structure. It is probably a mistake
-to use NULL for one of write_data_fn and output_flush_fn but not both
-of them, unless you have built libpng with PNG_NO_WRITE_FLUSH defined.
-It is an error to read from a write stream, and vice versa.
-
-Error handling in libpng is done through png_error() and png_warning().
-Errors handled through png_error() are fatal, meaning that png_error()
-should never return to its caller. Currently, this is handled via
-setjmp() and longjmp() (unless you have compiled libpng with
-PNG_NO_SETJMP, in which case it is handled via PNG_ABORT()),
-but you could change this to do things like exit() if you should wish,
-as long as your function does not return.
-
-On non-fatal errors, png_warning() is called
-to print a warning message, and then control returns to the calling code.
-By default png_error() and png_warning() print a message on stderr via
-fprintf() unless the library is compiled with PNG_NO_CONSOLE_IO defined
-(because you don't want the messages) or PNG_NO_STDIO defined (because
-fprintf() isn't available). If you wish to change the behavior of the error
-functions, you will need to set up your own message callbacks. These
-functions are normally supplied at the time that the png_struct is created.
-It is also possible to redirect errors and warnings to your own replacement
-functions after png_create_*_struct() has been called by calling:
-
- png_set_error_fn(png_structp png_ptr,
- png_voidp error_ptr, png_error_ptr error_fn,
- png_error_ptr warning_fn);
-
- png_voidp error_ptr = png_get_error_ptr(png_ptr);
-
-If NULL is supplied for either error_fn or warning_fn, then the libpng
-default function will be used, calling fprintf() and/or longjmp() if a
-problem is encountered. The replacement error functions should have
-parameters as follows:
-
- void user_error_fn(png_structp png_ptr,
- png_const_charp error_msg);
- void user_warning_fn(png_structp png_ptr,
- png_const_charp warning_msg);
-
-The motivation behind using setjmp() and longjmp() is the C++ throw and
-catch exception handling methods. This makes the code much easier to write,
-as there is no need to check every return code of every function call.
-However, there are some uncertainties about the status of local variables
-after a longjmp, so the user may want to be careful about doing anything
-after setjmp returns non-zero besides returning itself. Consult your
-compiler documentation for more details. For an alternative approach, you
-may wish to use the "cexcept" facility (see http://cexcept.sourceforge.net),
-which is illustrated in pngvalid.c and in contrib/visupng.
-
-Custom chunks
-
-If you need to read or write custom chunks, you may need to get deeper
-into the libpng code. The library now has mechanisms for storing
-and writing chunks of unknown type; you can even declare callbacks
-for custom chunks. However, this may not be good enough if the
-library code itself needs to know about interactions between your
-chunk and existing `intrinsic' chunks.
-
-If you need to write a new intrinsic chunk, first read the PNG
-specification. Acquire a first level of understanding of how it works.
-Pay particular attention to the sections that describe chunk names,
-and look at how other chunks were designed, so you can do things
-similarly. Second, check out the sections of libpng that read and
-write chunks. Try to find a chunk that is similar to yours and use
-it as a template. More details can be found in the comments inside
-the code. It is best to handle private or unknown chunks in a generic method,
-via callback functions, instead of by modifying libpng functions. This
-is illustrated in pngtest.c, which uses a callback function to handle a
-private "vpAg" chunk and the new "sTER" chunk, which are both unknown to
-libpng.
-
-If you wish to write your own transformation for the data, look through
-the part of the code that does the transformations, and check out some of
-the simpler ones to get an idea of how they work. Try to find a similar
-transformation to the one you want to add and copy off of it. More details
-can be found in the comments inside the code itself.
-
-Configuring for 16 bit platforms
-
-You will want to look into zconf.h to tell zlib (and thus libpng) that
-it cannot allocate more then 64K at a time. Even if you can, the memory
-won't be accessible. So limit zlib and libpng to 64K by defining MAXSEG_64K.
-
-Configuring for DOS
-
-For DOS users who only have access to the lower 640K, you will
-have to limit zlib's memory usage via a png_set_compression_mem_level()
-call. See zlib.h or zconf.h in the zlib library for more information.
-
-Configuring for Medium Model
-
-Libpng's support for medium model has been tested on most of the popular
-compilers. Make sure MAXSEG_64K gets defined, USE_FAR_KEYWORD gets
-defined, and FAR gets defined to far in pngconf.h, and you should be
-all set. Everything in the library (except for zlib's structure) is
-expecting far data. You must use the typedefs with the p or pp on
-the end for pointers (or at least look at them and be careful). Make
-note that the rows of data are defined as png_bytepp, which is an
-unsigned char far * far *.
-
-Configuring for gui/windowing platforms:
-
-You will need to write new error and warning functions that use the GUI
-interface, as described previously, and set them to be the error and
-warning functions at the time that png_create_*_struct() is called,
-in order to have them available during the structure initialization.
-They can be changed later via png_set_error_fn(). On some compilers,
-you may also have to change the memory allocators (png_malloc, etc.).
-
-Configuring for compiler xxx:
-
-All includes for libpng are in pngconf.h. If you need to add, change
-or delete an include, this is the place to do it.
-The includes that are not needed outside libpng are placed in pngpriv.h,
-which is only used by the routines inside libpng itself.
-The files in libpng proper only include pngpriv.h and png.h, which
-in turn includes pngconf.h.
-
-Configuring zlib:
-
-There are special functions to configure the compression. Perhaps the
-most useful one changes the compression level, which currently uses
-input compression values in the range 0 - 9. The library normally
-uses the default compression level (Z_DEFAULT_COMPRESSION = 6). Tests
-have shown that for a large majority of images, compression values in
-the range 3-6 compress nearly as well as higher levels, and do so much
-faster. For online applications it may be desirable to have maximum speed
-(Z_BEST_SPEED = 1). With versions of zlib after v0.99, you can also
-specify no compression (Z_NO_COMPRESSION = 0), but this would create
-files larger than just storing the raw bitmap. You can specify the
-compression level by calling:
-
- png_set_compression_level(png_ptr, level);
-
-Another useful one is to reduce the memory level used by the library.
-The memory level defaults to 8, but it can be lowered if you are
-short on memory (running DOS, for example, where you only have 640K).
-Note that the memory level does have an effect on compression; among
-other things, lower levels will result in sections of incompressible
-data being emitted in smaller stored blocks, with a correspondingly
-larger relative overhead of up to 15% in the worst case.
-
- png_set_compression_mem_level(png_ptr, level);
-
-The other functions are for configuring zlib. They are not recommended
-for normal use and may result in writing an invalid PNG file. See
-zlib.h for more information on what these mean.
-
- png_set_compression_strategy(png_ptr,
- strategy);
- png_set_compression_window_bits(png_ptr,
- window_bits);
- png_set_compression_method(png_ptr, method);
- png_set_compression_buffer_size(png_ptr, size);
-
-Controlling row filtering
-
-If you want to control whether libpng uses filtering or not, which
-filters are used, and how it goes about picking row filters, you
-can call one of these functions. The selection and configuration
-of row filters can have a significant impact on the size and
-encoding speed and a somewhat lesser impact on the decoding speed
-of an image. Filtering is enabled by default for RGB and grayscale
-images (with and without alpha), but not for paletted images nor
-for any images with bit depths less than 8 bits/pixel.
-
-The 'method' parameter sets the main filtering method, which is
-currently only '0' in the PNG 1.2 specification. The 'filters'
-parameter sets which filter(s), if any, should be used for each
-scanline. Possible values are PNG_ALL_FILTERS and PNG_NO_FILTERS
-to turn filtering on and off, respectively.
-
-Individual filter types are PNG_FILTER_NONE, PNG_FILTER_SUB,
-PNG_FILTER_UP, PNG_FILTER_AVG, PNG_FILTER_PAETH, which can be bitwise
-ORed together with '|' to specify one or more filters to use.
-These filters are described in more detail in the PNG specification.
-If you intend to change the filter type during the course of writing
-the image, you should start with flags set for all of the filters
-you intend to use so that libpng can initialize its internal
-structures appropriately for all of the filter types. (Note that this
-means the first row must always be adaptively filtered, because libpng
-currently does not allocate the filter buffers until png_write_row()
-is called for the first time.)
-
- filters = PNG_FILTER_NONE | PNG_FILTER_SUB
- PNG_FILTER_UP | PNG_FILTER_AVG |
- PNG_FILTER_PAETH | PNG_ALL_FILTERS;
-
- png_set_filter(png_ptr, PNG_FILTER_TYPE_BASE,
- filters);
- The second parameter can also be
- PNG_INTRAPIXEL_DIFFERENCING if you are
- writing a PNG to be embedded in a MNG
- datastream. This parameter must be the
- same as the value of filter_method used
- in png_set_IHDR().
-
-It is also possible to influence how libpng chooses from among the
-available filters. This is done in one or both of two ways - by
-telling it how important it is to keep the same filter for successive
-rows, and by telling it the relative computational costs of the filters.
-
- double weights[3] = {1.5, 1.3, 1.1},
- costs[PNG_FILTER_VALUE_LAST] =
- {1.0, 1.3, 1.3, 1.5, 1.7};
-
- png_set_filter_heuristics(png_ptr,
- PNG_FILTER_HEURISTIC_WEIGHTED, 3,
- weights, costs);
-
-The weights are multiplying factors that indicate to libpng that the
-row filter should be the same for successive rows unless another row filter
-is that many times better than the previous filter. In the above example,
-if the previous 3 filters were SUB, SUB, NONE, the SUB filter could have a
-"sum of absolute differences" 1.5 x 1.3 times higher than other filters
-and still be chosen, while the NONE filter could have a sum 1.1 times
-higher than other filters and still be chosen. Unspecified weights are
-taken to be 1.0, and the specified weights should probably be declining
-like those above in order to emphasize recent filters over older filters.
-
-The filter costs specify for each filter type a relative decoding cost
-to be considered when selecting row filters. This means that filters
-with higher costs are less likely to be chosen over filters with lower
-costs, unless their "sum of absolute differences" is that much smaller.
-The costs do not necessarily reflect the exact computational speeds of
-the various filters, since this would unduly influence the final image
-size.
-
-Note that the numbers above were invented purely for this example and
-are given only to help explain the function usage. Little testing has
-been done to find optimum values for either the costs or the weights.
-
-Removing unwanted object code
-
-There are a bunch of #define's in pngconf.h that control what parts of
-libpng are compiled. All the defines end in _SUPPORTED. If you are
-never going to use a capability, you can change the #define to #undef
-before recompiling libpng and save yourself code and data space, or
-you can turn off individual capabilities with defines that begin with
-PNG_NO_.
-
-You can also turn all of the transforms and ancillary chunk capabilities
-off en masse with compiler directives that define
-PNG_NO_READ[or WRITE]_TRANSFORMS, or PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS,
-or all four,
-along with directives to turn on any of the capabilities that you do
-want. The PNG_NO_READ[or WRITE]_TRANSFORMS directives disable the extra
-transformations but still leave the library fully capable of reading
-and writing PNG files with all known public chunks. Use of the
-PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS directive produces a library
-that is incapable of reading or writing ancillary chunks. If you are
-not using the progressive reading capability, you can turn that off
-with PNG_NO_PROGRESSIVE_READ (don't confuse this with the INTERLACING
-capability, which you'll still have).
-
-All the reading and writing specific code are in separate files, so the
-linker should only grab the files it needs. However, if you want to
-make sure, or if you are building a stand alone library, all the
-reading files start with "pngr" and all the writing files start with "pngw".
-The files that don't match either (like png.c, pngtrans.c, etc.)
-are used for both reading and writing, and always need to be included.
-The progressive reader is in pngpread.c
-
-If you are creating or distributing a dynamically linked library (a .so
-or DLL file), you should not remove or disable any parts of the library,
-as this will cause applications linked with different versions of the
-library to fail if they call functions not available in your library.
-The size of the library itself should not be an issue, because only
-those sections that are actually used will be loaded into memory.
-
-Requesting debug printout
-
-The macro definition PNG_DEBUG can be used to request debugging
-printout. Set it to an integer value in the range 0 to 3. Higher
-numbers result in increasing amounts of debugging information. The
-information is printed to the "stderr" file, unless another file
-name is specified in the PNG_DEBUG_FILE macro definition.
-
-When PNG_DEBUG > 0, the following functions (macros) become available:
-
- png_debug(level, message)
- png_debug1(level, message, p1)
- png_debug2(level, message, p1, p2)
-
-in which "level" is compared to PNG_DEBUG to decide whether to print
-the message, "message" is the formatted string to be printed,
-and p1 and p2 are parameters that are to be embedded in the string
-according to printf-style formatting directives. For example,
-
- png_debug1(2, "foo=%d\n", foo);
-
-is expanded to
-
- if(PNG_DEBUG > 2)
- fprintf(PNG_DEBUG_FILE, "foo=%d\n", foo);
-
-When PNG_DEBUG is defined but is zero, the macros aren't defined, but you
-can still use PNG_DEBUG to control your own debugging:
-
- #ifdef PNG_DEBUG
- fprintf(stderr, ...
- #endif
-
-When PNG_DEBUG = 1, the macros are defined, but only png_debug statements
-having level = 0 will be printed. There aren't any such statements in
-this version of libpng, but if you insert some they will be printed.
-
-VI. MNG support
-
-The MNG specification (available at http://www.libpng.org/pub/mng) allows
-certain extensions to PNG for PNG images that are embedded in MNG datastreams.
-Libpng can support some of these extensions. To enable them, use the
-png_permit_mng_features() function:
-
- feature_set = png_permit_mng_features(png_ptr, mask)
- mask is a png_uint_32 containing the bitwise OR of the
- features you want to enable. These include
- PNG_FLAG_MNG_EMPTY_PLTE
- PNG_FLAG_MNG_FILTER_64
- PNG_ALL_MNG_FEATURES
- feature_set is a png_uint_32 that is the bitwise AND of
- your mask with the set of MNG features that is
- supported by the version of libpng that you are using.
-
-It is an error to use this function when reading or writing a standalone
-PNG file with the PNG 8-byte signature. The PNG datastream must be wrapped
-in a MNG datastream. As a minimum, it must have the MNG 8-byte signature
-and the MHDR and MEND chunks. Libpng does not provide support for these
-or any other MNG chunks; your application must provide its own support for
-them. You may wish to consider using libmng (available at
-http://www.libmng.com) instead.
-
-VII. Changes to Libpng from version 0.88
-
-It should be noted that versions of libpng later than 0.96 are not
-distributed by the original libpng author, Guy Schalnat, nor by
-Andreas Dilger, who had taken over from Guy during 1996 and 1997, and
-distributed versions 0.89 through 0.96, but rather by another member
-of the original PNG Group, Glenn Randers-Pehrson. Guy and Andreas are
-still alive and well, but they have moved on to other things.
-
-The old libpng functions png_read_init(), png_write_init(),
-png_info_init(), png_read_destroy(), and png_write_destroy() have been
-moved to PNG_INTERNAL in version 0.95 to discourage their use. These
-functions will be removed from libpng version 2.0.0.
-
-The preferred method of creating and initializing the libpng structures is
-via the png_create_read_struct(), png_create_write_struct(), and
-png_create_info_struct() because they isolate the size of the structures
-from the application, allow version error checking, and also allow the
-use of custom error handling routines during the initialization, which
-the old functions do not. The functions png_read_destroy() and
-png_write_destroy() do not actually free the memory that libpng
-allocated for these structs, but just reset the data structures, so they
-can be used instead of png_destroy_read_struct() and
-png_destroy_write_struct() if you feel there is too much system overhead
-allocating and freeing the png_struct for each image read.
-
-Setting the error callbacks via png_set_message_fn() before
-png_read_init() as was suggested in libpng-0.88 is no longer supported
-because this caused applications that do not use custom error functions
-to fail if the png_ptr was not initialized to zero. It is still possible
-to set the error callbacks AFTER png_read_init(), or to change them with
-png_set_error_fn(), which is essentially the same function, but with a new
-name to force compilation errors with applications that try to use the old
-method.
-
-Starting with version 1.0.7, you can find out which version of the library
-you are using at run-time:
-
- png_uint_32 libpng_vn = png_access_version_number();
-
-The number libpng_vn is constructed from the major version, minor
-version with leading zero, and release number with leading zero,
-(e.g., libpng_vn for version 1.0.7 is 10007).
-
-You can also check which version of png.h you used when compiling your
-application:
-
- png_uint_32 application_vn = PNG_LIBPNG_VER;
-
-VIII. Changes to Libpng from version 1.0.x to 1.2.x
-
-Support for user memory management was enabled by default. To
-accomplish this, the functions png_create_read_struct_2(),
-png_create_write_struct_2(), png_set_mem_fn(), png_get_mem_ptr(),
-png_malloc_default(), and png_free_default() were added.
-
-Support for the iTXt chunk has been enabled by default as of
-version 1.2.41.
-
-Support for certain MNG features was enabled.
-
-Support for numbered error messages was added. However, we never got
-around to actually numbering the error messages. The function
-png_set_strip_error_numbers() was added (Note: the prototype for this
-function was inadvertently removed from png.h in PNG_NO_ASSEMBLER_CODE
-builds of libpng-1.2.15. It was restored in libpng-1.2.36).
-
-The png_malloc_warn() function was added at libpng-1.2.3. This issues
-a png_warning and returns NULL instead of aborting when it fails to
-acquire the requested memory allocation.
-
-Support for setting user limits on image width and height was enabled
-by default. The functions png_set_user_limits(), png_get_user_width_max(),
-and png_get_user_height_max() were added at libpng-1.2.6.
-
-The png_set_add_alpha() function was added at libpng-1.2.7.
-
-The function png_set_expand_gray_1_2_4_to_8() was added at libpng-1.2.9.
-Unlike png_set_gray_1_2_4_to_8(), the new function does not expand the
-tRNS chunk to alpha. The png_set_gray_1_2_4_to_8() function is
-deprecated.
-
-A number of macro definitions in support of runtime selection of
-assembler code features (especially Intel MMX code support) were
-added at libpng-1.2.0:
-
- PNG_ASM_FLAG_MMX_SUPPORT_COMPILED
- PNG_ASM_FLAG_MMX_SUPPORT_IN_CPU
- PNG_ASM_FLAG_MMX_READ_COMBINE_ROW
- PNG_ASM_FLAG_MMX_READ_INTERLACE
- PNG_ASM_FLAG_MMX_READ_FILTER_SUB
- PNG_ASM_FLAG_MMX_READ_FILTER_UP
- PNG_ASM_FLAG_MMX_READ_FILTER_AVG
- PNG_ASM_FLAG_MMX_READ_FILTER_PAETH
- PNG_ASM_FLAGS_INITIALIZED
- PNG_MMX_READ_FLAGS
- PNG_MMX_FLAGS
- PNG_MMX_WRITE_FLAGS
- PNG_MMX_FLAGS
-
-We added the following functions in support of runtime
-selection of assembler code features:
-
- png_get_mmx_flagmask()
- png_set_mmx_thresholds()
- png_get_asm_flags()
- png_get_mmx_bitdepth_threshold()
- png_get_mmx_rowbytes_threshold()
- png_set_asm_flags()
-
-We replaced all of these functions with simple stubs in libpng-1.2.20,
-when the Intel assembler code was removed due to a licensing issue.
-
-These macros are deprecated:
-
- PNG_READ_TRANSFORMS_NOT_SUPPORTED
- PNG_PROGRESSIVE_READ_NOT_SUPPORTED
- PNG_NO_SEQUENTIAL_READ_SUPPORTED
- PNG_WRITE_TRANSFORMS_NOT_SUPPORTED
- PNG_READ_ANCILLARY_CHUNKS_NOT_SUPPORTED
- PNG_WRITE_ANCILLARY_CHUNKS_NOT_SUPPORTED
-
-They have been replaced, respectively, by:
-
- PNG_NO_READ_TRANSFORMS
- PNG_NO_PROGRESSIVE_READ
- PNG_NO_SEQUENTIAL_READ
- PNG_NO_WRITE_TRANSFORMS
- PNG_NO_READ_ANCILLARY_CHUNKS
- PNG_NO_WRITE_ANCILLARY_CHUNKS
-
-PNG_MAX_UINT was replaced with PNG_UINT_31_MAX. It has been
-deprecated since libpng-1.0.16 and libpng-1.2.6.
-
-The function
- png_check_sig(sig, num)
-was replaced with
- !png_sig_cmp(sig, 0, num)
-It has been deprecated since libpng-0.90.
-
-The function
- png_set_gray_1_2_4_to_8()
-which also expands tRNS to alpha was replaced with
- png_set_expand_gray_1_2_4_to_8()
-which does not. It has been deprecated since libpng-1.0.18 and 1.2.9.
-
-IX. Changes to Libpng from version 1.0.x/1.2.x to 1.4.x
-
-Private libpng prototypes and macro definitions were moved from
-png.h and pngconf.h into a new pngpriv.h header file.
-
-Functions png_set_benign_errors(), png_benign_error(), and
-png_chunk_benign_error() were added.
-
-Support for setting the maximum amount of memory that the application
-will allocate for reading chunks was added, as a security measure.
-The functions png_set_chunk_cache_max() and png_get_chunk_cache_max()
-were added to the library.
-
-We implemented support for I/O states by adding png_ptr member io_state
-and functions png_get_io_chunk_name() and png_get_io_state() in pngget.c
-
-We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
-input transforms.
-
-Checking for and reporting of errors in the IHDR chunk is more thorough.
-
-Support for global arrays was removed, to improve thread safety.
-
-Some obsolete/deprecated macros and functions have been removed.
-
-Typecasted NULL definitions such as
- #define png_voidp_NULL (png_voidp)NULL
-were eliminated. If you used these in your application, just use
-NULL instead.
-
-The png_struct and info_struct members "trans" and "trans_values" were
-changed to "trans_alpha" and "trans_color", respectively.
-
-The obsolete, unused pnggccrd.c and pngvcrd.c files and related makefiles
-were removed.
-
-The PNG_1_0_X and PNG_1_2_X macros were eliminated.
-
-The PNG_LEGACY_SUPPORTED macro was eliminated.
-
-Many WIN32_WCE #ifdefs were removed.
-
-The functions png_read_init(info_ptr), png_write_init(info_ptr),
-png_info_init(info_ptr), png_read_destroy(), and png_write_destroy()
-have been removed. They have been deprecated since libpng-0.95.
-
-The png_permit_empty_plte() was removed. It has been deprecated
-since libpng-1.0.9. Use png_permit_mng_features() instead.
-
-We removed the obsolete stub functions png_get_mmx_flagmask(),
-png_set_mmx_thresholds(), png_get_asm_flags(),
-png_get_mmx_bitdepth_threshold(), png_get_mmx_rowbytes_threshold(),
-png_set_asm_flags(), and png_mmx_supported()
-
-We removed the obsolete png_check_sig(), png_memcpy_check(), and
-png_memset_check() functions. Instead use !png_sig_cmp(), png_memcpy(),
-and png_memset(), respectively.
-
-The function png_set_gray_1_2_4_to_8() was removed. It has been
-deprecated since libpng-1.0.18 and 1.2.9, when it was replaced with
-png_set_expand_gray_1_2_4_to_8() because the former function also
-expanded palette images.
-
-Macros for png_get_uint_16, png_get_uint_32, and png_get_int_32
-were added and are used by default instead of the corresponding
-functions. Unfortunately,
-from libpng-1.4.0 until 1.4.4, the png_get_uint_16 macro (but not the
-function) incorrectly returned a value of type png_uint_32.
-
-We changed the prototype for png_malloc() from
- png_malloc(png_structp png_ptr, png_uint_32 size)
-to
- png_malloc(png_structp png_ptr, png_alloc_size_t size)
-
-This also applies to the prototype for the user replacement malloc_fn().
-
-The png_calloc() function was added and is used in place of
-of "png_malloc(); png_memset();" except in the case in png_read_png()
-where the array consists of pointers; in this case a "for" loop is used
-after the png_malloc() to set the pointers to NULL, to give robust.
-behavior in case the application runs out of memory part-way through
-the process.
-
-We changed the prototypes of png_get_compression_buffer_size() and
-png_set_compression_buffer_size() to work with png_size_t instead of
-png_uint_32.
-
-Support for numbered error messages was removed by default, since we
-never got around to actually numbering the error messages. The function
-png_set_strip_error_numbers() was removed from the library by default.
-
-The png_zalloc() and png_zfree() functions are no longer exported.
-The png_zalloc() function no longer zeroes out the memory that it
-allocates.
-
-Support for dithering was disabled by default in libpng-1.4.0, because
-it has not been well tested and doesn't actually "dither".
-The code was not
-removed, however, and could be enabled by building libpng with
-PNG_READ_DITHER_SUPPORTED defined. In libpng-1.4.2, this support
-was reenabled, but the function was renamed png_set_quantize() to
-reflect more accurately what it actually does. At the same time,
-the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros were also renamed to
-PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS.
-
-We removed the trailing '.' from the warning and error messages.
-
-X. Detecting libpng
-
-The png_get_io_ptr() function has been present since libpng-0.88, has never
-changed, and is unaffected by conditional compilation macros. It is the
-best choice for use in configure scripts for detecting the presence of any
-libpng version since 0.88. In an autoconf "configure.in" you could use
-
- AC_CHECK_LIB(png, png_get_io_ptr, ...
-
-XI. Source code repository
-
-Since about February 2009, version 1.2.34, libpng has been under "git" source
-control. The git repository was built from old libpng-x.y.z.tar.gz files
-going back to version 0.70. You can access the git repository (read only)
-at
-
- git://libpng.git.sourceforge.net/gitroot/libpng
-
-or you can browse it via "gitweb" at
-
- http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng
-
-Patches can be sent to glennrp at users.sourceforge.net or to
-png-mng-implement at lists.sourceforge.net or you can upload them to
-the libpng bug tracker at
-
- http://libpng.sourceforge.net
-
-XII. Coding style
-
-Our coding style is similar to the "Allman" style, with curly
-braces on separate lines:
-
- if (condition)
- {
- action;
- }
-
- else if (another condition)
- {
- another action;
- }
-
-The braces can be omitted from simple one-line actions:
-
- if (condition)
- return (0);
-
-We use 3-space indentation, except for continued statements which
-are usually indented the same as the first line of the statement
-plus four more spaces.
-
-For macro definitions we use 2-space indentation, always leaving the "#"
-in the first column.
-
- #ifndef PNG_NO_FEATURE
- # ifndef PNG_FEATURE_SUPPORTED
- # define PNG_FEATURE_SUPPORTED
- # endif
- #endif
-
-Comments appear with the leading "/*" at the same indentation as
-the statement that follows the comment:
-
- /* Single-line comment */
- statement;
-
- /* This is a multiple-line
- * comment.
- */
- statement;
-
-Very short comments can be placed after the end of the statement
-to which they pertain:
-
- statement; /* comment */
-
-We don't use C++ style ("//") comments. We have, however,
-used them in the past in some now-abandoned MMX assembler
-code.
-
-Functions and their curly braces are not indented, and
-exported functions are marked with PNGAPI:
-
- /* This is a public function that is visible to
- * application programers. It does thus-and-so.
- */
- void PNGAPI
- png_exported_function(png_ptr, png_info, foo)
- {
- body;
- }
-
-The prototypes for all exported functions appear in png.h,
-above the comment that says
-
- /* Maintainer: Put new public prototypes here ... */
-
-We mark all non-exported functions with "/* PRIVATE */"":
-
- void /* PRIVATE */
- png_non_exported_function(png_ptr, png_info, foo)
- {
- body;
- }
-
-The prototypes for non-exported functions (except for those in
-pngtest) appear in
-pngpriv.h
-above the comment that says
-
- /* Maintainer: Put new private prototypes here ^ and in libpngpf.3 */
-
-To avoid polluting the global namespace, the names of all exported
-functions and variables begin with "png_", and all publicly visible C
-preprocessor macros begin with "PNG". We request that applications that
-use libpng *not* begin any of their own symbols with either of these strings.
-
-We put a space after each comma and after each semicolon
-in "for" statments, and we put spaces before and after each
-C binary operator and after "for" or "while", and before
-"?". We don't put a space between a typecast and the expression
-being cast, nor do we put one between a function name and the
-left parenthesis that follows it:
-
- for (i = 2; i > 0; --i)
- y[i] = a(x) + (int)b;
-
-We prefer #ifdef and #ifndef to #if defined() and if !defined()
-when there is only one macro being tested.
-
-We do not use the TAB character for indentation in the C sources.
-
-Lines do not exceed 80 characters.
-
-Other rules can be inferred by inspecting the libpng source.
-
-XIII. Y2K Compliance in libpng
-
-July 10, 2012
-
-Since the PNG Development group is an ad-hoc body, we can't make
-an official declaration.
-
-This is your unofficial assurance that libpng from version 0.71 and
-upward through 1.4.12 are Y2K compliant. It is my belief that earlier
-versions were also Y2K compliant.
-
-Libpng only has three year fields. One is a 2-byte unsigned integer that
-will hold years up to 65535. The other two hold the date in text
-format, and will hold years up to 9999.
-
-The integer is
- "png_uint_16 year" in png_time_struct.
-
-The strings are
- "png_charp time_buffer" in png_struct and
- "near_time_buffer", which is a local character string in png.c.
-
-There are seven time-related functions:
-
- png_convert_to_rfc_1123() in png.c
- (formerly png_convert_to_rfc_1152() in error)
- png_convert_from_struct_tm() in pngwrite.c, called
- in pngwrite.c
- png_convert_from_time_t() in pngwrite.c
- png_get_tIME() in pngget.c
- png_handle_tIME() in pngrutil.c, called in pngread.c
- png_set_tIME() in pngset.c
- png_write_tIME() in pngwutil.c, called in pngwrite.c
-
-All appear to handle dates properly in a Y2K environment. The
-png_convert_from_time_t() function calls gmtime() to convert from system
-clock time, which returns (year - 1900), which we properly convert to
-the full 4-digit year. There is a possibility that applications using
-libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
-function, or that they are incorrectly passing only a 2-digit year
-instead of "year - 1900" into the png_convert_from_struct_tm() function,
-but this is not under our control. The libpng documentation has always
-stated that it works with 4-digit years, and the APIs have been
-documented as such.
-
-The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
-integer to hold the year, and can hold years as large as 65535.
-
-zlib, upon which libpng depends, is also Y2K compliant. It contains
-no date-related code.

-.SH I. Introduction
-
-This file describes how to use and modify the PNG reference library
-(known as libpng) for your own use. There are five sections to this
-file: introduction, structures, reading, writing, and modification and
-configuration notes for various special platforms. In addition to this
-file, example.c is a good starting point for using the library, as
-it is heavily commented and should include everything most people
-will need. We assume that libpng is already installed; see the
-INSTALL file for instructions on how to install libpng.
-
-For examples of libpng usage, see the files "example.c", "pngtest.c",
-and the files in the "contrib" directory, all of which are included in
-the libpng distribution.
-
-Libpng was written as a companion to the PNG specification, as a way
-of reducing the amount of time and effort it takes to support the PNG
-file format in application programs.
-
-The PNG specification (second edition), November 2003, is available as
-a W3C Recommendation and as an ISO Standard (ISO/IEC 15948:2003 (E)) at
-<http://www.w3.org/TR/2003/REC-PNG-20031110/
-The W3C and ISO documents have identical technical content.
-
-The PNG-1.2 specification is available at
-<http://www.libpng.org/pub/png/documents/>. It is technically equivalent
-to the PNG specification (second edition) but has some additional material.
-
-The PNG-1.0 specification is available
-as RFC 2083 <http://www.libpng.org/pub/png/documents/> and as a
-W3C Recommendation <http://www.w3.org/TR/REC.png.html>.
-
-Some additional chunks are described in the special-purpose public chunks
-documents at <http://www.libpng.org/pub/png/documents/>.
-
-Other information
-about PNG, and the latest version of libpng, can be found at the PNG home
-page, <http://www.libpng.org/pub/png/>.
-
-Most users will not have to modify the library significantly; advanced
-users may want to modify it more. All attempts were made to make it as
-complete as possible, while keeping the code easy to understand.
-Currently, this library only supports C. Support for other languages
-is being considered.
-
-Libpng has been designed to handle multiple sessions at one time,
-to be easily modifiable, to be portable to the vast majority of
-machines (ANSI, K&R, 16-, 32-, and 64-bit) available, and to be easy
-to use. The ultimate goal of libpng is to promote the acceptance of
-the PNG file format in whatever way possible. While there is still
-work to be done (see the TODO file), libpng should cover the
-majority of the needs of its users.
-
-Libpng uses zlib for its compression and decompression of PNG files.
-Further information about zlib, and the latest version of zlib, can
-be found at the zlib home page, <http://www.info-zip.org/pub/infozip/zlib/>.
-The zlib compression utility is a general purpose utility that is
-useful for more than PNG files, and can be used without libpng.
-See the documentation delivered with zlib for more details.
-You can usually find the source files for the zlib utility wherever you
-find the libpng source files.
-
-Libpng is thread safe, provided the threads are using different
-instances of the structures. Each thread should have its own
-png_struct and png_info instances, and thus its own image.
-Libpng does not protect itself against two threads using the
-same instance of a structure.
-
-.SH II. Structures
-
-There are two main structures that are important to libpng, png_struct
-and png_info. The first, png_struct, is an internal structure that
-will not, for the most part, be used by a user except as the first
-variable passed to every libpng function call.
-
-The png_info structure is designed to provide information about the
-PNG file. At one time, the fields of png_info were intended to be
-directly accessible to the user. However, this tended to cause problems
-with applications using dynamically loaded libraries, and as a result
-a set of interface functions for png_info (the png_get_*() and png_set_*()
-functions) was developed. The fields of png_info are still available for
-older applications, but it is suggested that applications use the new
-interfaces if at all possible.
-
-Applications that do make direct access to the members of png_struct (except
-for png_ptr->jmpbuf) must be recompiled whenever the library is updated,
-and applications that make direct access to the members of png_info must
-be recompiled if they were compiled or loaded with libpng version 1.0.6,
-in which the members were in a different order. In version 1.0.7, the
-members of the png_info structure reverted to the old order, as they were
-in versions 0.97c through 1.0.5. Starting with version 2.0.0, both
-structures are going to be hidden, and the contents of the structures will
-only be accessible through the png_get/png_set functions.
-
-The png.h header file is an invaluable reference for programming with libpng.
-And while I'm on the topic, make sure you include the libpng header file:
-
-#include <png.h>
-
-.SH III. Reading
-
-We'll now walk you through the possible functions to call when reading
-in a PNG file sequentially, briefly explaining the syntax and purpose
-of each one. See example.c and png.h for more detail. While
-progressive reading is covered in the next section, you will still
-need some of the functions discussed in this section to read a PNG
-file.
-
-.SS Setup
-
-You will want to do the I/O initialization(*) before you get into libpng,
-so if it doesn't work, you don't have much to undo. Of course, you
-will also want to insure that you are, in fact, dealing with a PNG
-file. Libpng provides a simple check to see if a file is a PNG file.
-To use it, pass in the first 1 to 8 bytes of the file to the function
-png_sig_cmp(), and it will return 0 (false) if the bytes match the
-corresponding bytes of the PNG signature, or nonzero (true) otherwise.
-Of course, the more bytes you pass in, the greater the accuracy of the
-prediction.
-
-If you are intending to keep the file pointer open for use in libpng,
-you must ensure you don't read more than 8 bytes from the beginning
-of the file, and you also have to make a call to png_set_sig_bytes_read()
-with the number of bytes you read from the beginning. Libpng will
-then only check the bytes (if any) that your program didn't read.
-
-(*): If you are not using the standard I/O functions, you will need
-to replace them with custom functions. See the discussion under
-Customizing libpng.
-
-
- FILE *fp = fopen(file_name, "rb");
- if (!fp)
- {
- return (ERROR);
- }
- fread(header, 1, number, fp);
- is_png = !png_sig_cmp(header, 0, number);
- if (!is_png)
- {
- return (NOT_PNG);
- }
-
-
-Next, png_struct and png_info need to be allocated and initialized. In
-order to ensure that the size of these structures is correct even with a
-dynamically linked libpng, there are functions to initialize and
-allocate the structures. We also pass the library version, optional
-pointers to error handling functions, and a pointer to a data struct for
-use by the error functions, if necessary (the pointer and functions can
-be NULL if the default error handlers are to be used). See the section
-on Changes to Libpng below regarding the old initialization functions.
-The structure allocation functions quietly return NULL if they fail to
-create the structure, so your application should check for that.
-
- png_structp png_ptr = png_create_read_struct
- (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
- user_error_fn, user_warning_fn);
- if (!png_ptr)
- return (ERROR);
-
- png_infop info_ptr = png_create_info_struct(png_ptr);
- if (!info_ptr)
- {
- png_destroy_read_struct(&png_ptr,
- (png_infopp)NULL, (png_infopp)NULL);
- return (ERROR);
- }
-
- png_infop end_info = png_create_info_struct(png_ptr);
- if (!end_info)
- {
- png_destroy_read_struct(&png_ptr, &info_ptr,
- (png_infopp)NULL);
- return (ERROR);
- }
-
-If you want to use your own memory allocation routines,
-define PNG_USER_MEM_SUPPORTED and use
-png_create_read_struct_2() instead of png_create_read_struct():
-
- png_structp png_ptr = png_create_read_struct_2
- (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
- user_error_fn, user_warning_fn, (png_voidp)
- user_mem_ptr, user_malloc_fn, user_free_fn);
-
-The error handling routines passed to png_create_read_struct()
-and the memory alloc/free routines passed to png_create_struct_2()
-are only necessary if you are not using the libpng supplied error
-handling and memory alloc/free functions.
-
-When libpng encounters an error, it expects to longjmp back
-to your routine. Therefore, you will need to call setjmp and pass
-your png_jmpbuf(png_ptr). If you read the file from different
-routines, you will need to update the jmpbuf field every time you enter
-a new routine that will call a png_*() function.
-
-See your documentation of setjmp/longjmp for your compiler for more
-information on setjmp/longjmp. See the discussion on libpng error
-handling in the Customizing Libpng section below for more information
-on the libpng error handling. If an error occurs, and libpng longjmp's
-back to your setjmp, you will want to call png_destroy_read_struct() to
-free any memory.
-
- if (setjmp(png_jmpbuf(png_ptr)))
- {
- png_destroy_read_struct(&png_ptr, &info_ptr,
- &end_info);
- fclose(fp);
- return (ERROR);
- }
-
-If you would rather avoid the complexity of setjmp/longjmp issues,
-you can compile libpng with PNG_NO_SETJMP, in which case
-errors will result in a call to PNG_ABORT() which defaults to abort().
-
-You can #define PNG_ABORT() to a function that does something
-more useful than abort(), as long as your function does not
-return.
-
-Now you need to set up the input code. The default for libpng is to
-use the C function fread(). If you use this, you will need to pass a
-valid FILE * in the function png_init_io(). Be sure that the file is
-opened in binary mode. If you wish to handle reading data in another
-way, you need not call the png_init_io() function, but you must then
-implement the libpng I/O methods discussed in the Customizing Libpng
-section below.
-
- png_init_io(png_ptr, fp);
-
-If you had previously opened the file and read any of the signature from
-the beginning in order to see if this was a PNG file, you need to let
-libpng know that there are some bytes missing from the start of the file.
-
- png_set_sig_bytes(png_ptr, number);
-
-You can change the zlib compression buffer size to be used while
-reading compressed data with
-
- png_set_compression_buffer_size(png_ptr, buffer_size);
-
-where the default size is 8192 bytes. Note that the buffer size
-is changed immediately and the buffer is reallocated immediately,
-instead of setting a flag to be acted upon later.
-
-.SS Setting up callback code
-
-You can set up a callback function to handle any unknown chunks in the
-input stream. You must supply the function
-
- read_chunk_callback(png_structp png_ptr,
- png_unknown_chunkp chunk);
- {
- /* The unknown chunk structure contains your
- chunk data, along with similar data for any other
- unknown chunks: */
-
- png_byte name[5];
- png_byte *data;
- png_size_t size;
-
- /* Note that libpng has already taken care of
- the CRC handling */
-
- /* put your code here. Search for your chunk in the
- unknown chunk structure, process it, and return one
- of the following: */
-
- return (-n); /* chunk had an error */
- return (0); /* did not recognize */
- return (n); /* success */
- }
-
-(You can give your function another name that you like instead of
-"read_chunk_callback")
-
-To inform libpng about your function, use
-
- png_set_read_user_chunk_fn(png_ptr, user_chunk_ptr,
- read_chunk_callback);
-
-This names not only the callback function, but also a user pointer that
-you can retrieve with
-
- png_get_user_chunk_ptr(png_ptr);
-
-If you call the png_set_read_user_chunk_fn() function, then all unknown
-chunks will be saved when read, in case your callback function will need
-one or more of them. This behavior can be changed with the
-png_set_keep_unknown_chunks() function, described below.
-
-At this point, you can set up a callback function that will be
-called after each row has been read, which you can use to control
-a progress meter or the like. It's demonstrated in pngtest.c.
-You must supply a function
-
- void read_row_callback(png_structp png_ptr,
- png_uint_32 row, int pass);
- {
- /* put your code here */
- }
-
-(You can give it another name that you like instead of "read_row_callback")
-
-To inform libpng about your function, use
-
- png_set_read_status_fn(png_ptr, read_row_callback);
-
-.SS Unknown-chunk handling
-
-Now you get to set the way the library processes unknown chunks in the
-input PNG stream. Both known and unknown chunks will be read. Normal
-behavior is that known chunks will be parsed into information in
-various info_ptr members while unknown chunks will be discarded. This
-behavior can be wasteful if your application will never use some known
-chunk types. To change this, you can call:
-
- png_set_keep_unknown_chunks(png_ptr, keep,
- chunk_list, num_chunks);
- keep - 0: default unknown chunk handling
- 1: ignore; do not keep
- 2: keep only if safe-to-copy
- 3: keep even if unsafe-to-copy
- You can use these definitions:
- PNG_HANDLE_CHUNK_AS_DEFAULT 0
- PNG_HANDLE_CHUNK_NEVER 1
- PNG_HANDLE_CHUNK_IF_SAFE 2
- PNG_HANDLE_CHUNK_ALWAYS 3
- chunk_list - list of chunks affected (a byte string,
- five bytes per chunk, NULL or '\0' if
- num_chunks is 0)
- num_chunks - number of chunks affected; if 0, all
- unknown chunks are affected. If nonzero,
- only the chunks in the list are affected
-
-Unknown chunks declared in this way will be saved as raw data onto a
-list of png_unknown_chunk structures. If a chunk that is normally
-known to libpng is named in the list, it will be handled as unknown,
-according to the "keep" directive. If a chunk is named in successive
-instances of png_set_keep_unknown_chunks(), the final instance will
-take precedence. The IHDR and IEND chunks should not be named in
-chunk_list; if they are, libpng will process them normally anyway.
-
-Here is an example of the usage of png_set_keep_unknown_chunks(),
-where the private "vpAg" chunk will later be processed by a user chunk
-callback function:
-
- png_byte vpAg[5]={118, 112, 65, 103, (png_byte) '\0'};
-
- #if defined(PNG_UNKNOWN_CHUNKS_SUPPORTED)
- png_byte unused_chunks[]=
- {
- 104, 73, 83, 84, (png_byte) '\0', /* hIST */
- 105, 84, 88, 116, (png_byte) '\0', /* iTXt */
- 112, 67, 65, 76, (png_byte) '\0', /* pCAL */
- 115, 67, 65, 76, (png_byte) '\0', /* sCAL */
- 115, 80, 76, 84, (png_byte) '\0', /* sPLT */
- 116, 73, 77, 69, (png_byte) '\0', /* tIME */
- };
- #endif
-
- ...
-
- #if defined(PNG_UNKNOWN_CHUNKS_SUPPORTED)
- /* ignore all unknown chunks: */
- png_set_keep_unknown_chunks(read_ptr, 1, NULL, 0);
- /* except for vpAg: */
- png_set_keep_unknown_chunks(read_ptr, 2, vpAg, 1);
- /* also ignore unused known chunks: */
- png_set_keep_unknown_chunks(read_ptr, 1, unused_chunks,
- (int)sizeof(unused_chunks)/5);
- #endif
-
-.SS User limits
-
-The PNG specification allows the width and height of an image to be as
-large as 2^31-1 (0x7fffffff), or about 2.147 billion rows and columns.
-Since very few applications really need to process such large images,
-we have imposed an arbitrary 1-million limit on rows and columns.
-Larger images will be rejected immediately with a png_error() call. If
-you wish to override this limit, you can use
-
- png_set_user_limits(png_ptr, width_max, height_max);
-
-to set your own limits, or use width_max = height_max = 0x7fffffffL
-to allow all valid dimensions (libpng may reject some very large images
-anyway because of potential buffer overflow conditions).
-
-You should put this statement after you create the PNG structure and
-before calling png_read_info(), png_read_png(), or png_process_data().
-If you need to retrieve the limits that are being applied, use
-
- width_max = png_get_user_width_max(png_ptr);
- height_max = png_get_user_height_max(png_ptr);
-
-The PNG specification sets no limit on the number of ancillary chunks
-allowed in a PNG datastream. You can impose a limit on the total number
-of sPLT, tEXt, iTXt, zTXt, and unknown chunks that will be stored, with
-
- png_set_chunk_cache_max(png_ptr, user_chunk_cache_max);
-
-where 0x7fffffffL means unlimited. You can retrieve this limit with
-
- chunk_cache_max = png_get_chunk_cache_max(png_ptr);
-
-This limit also applies to the number of buffers that can be allocated
-by png_decompress_chunk() while decompressing iTXt, zTXt, and iCCP chunks.
-
-You can also set a limit on the amount of memory that a compressed chunk
-other than IDAT can occupy, with
-
- png_set_chunk_malloc_max(png_ptr, user_chunk_malloc_max);
-
-and you can retrieve the limit with
-
- chunk_malloc_max = png_get_chunk_malloc_max(png_ptr);
-
-Any chunks that would cause either of these limits to be exceeded will
-be ignored.
-
-.SS The high-level read interface
-
-At this point there are two ways to proceed; through the high-level
-read interface, or through a sequence of low-level read operations.
-You can use the high-level interface if (a) you are willing to read
-the entire image into memory, and (b) the input transformations
-you want to do are limited to the following set:
-
- PNG_TRANSFORM_IDENTITY No transformation
- PNG_TRANSFORM_STRIP_16 Strip 16-bit samples to
- 8 bits
- PNG_TRANSFORM_STRIP_ALPHA Discard the alpha channel
- PNG_TRANSFORM_PACKING Expand 1, 2 and 4-bit
- samples to bytes
- PNG_TRANSFORM_PACKSWAP Change order of packed
- pixels to LSB first
- PNG_TRANSFORM_EXPAND Perform set_expand()
- PNG_TRANSFORM_INVERT_MONO Invert monochrome images
- PNG_TRANSFORM_SHIFT Normalize pixels to the
- sBIT depth
- PNG_TRANSFORM_BGR Flip RGB to BGR, RGBA
- to BGRA
- PNG_TRANSFORM_SWAP_ALPHA Flip RGBA to ARGB or GA
- to AG
- PNG_TRANSFORM_INVERT_ALPHA Change alpha from opacity
- to transparency
- PNG_TRANSFORM_SWAP_ENDIAN Byte-swap 16-bit samples
- PNG_TRANSFORM_GRAY_TO_RGB Expand grayscale samples
- to RGB (or GA to RGBA)
-
-(This excludes setting a background color, doing gamma transformation,
-quantizing, and setting filler.) If this is the case, simply do this:
-
- png_read_png(png_ptr, info_ptr, png_transforms, NULL)
-
-where png_transforms is an integer containing the bitwise OR of some
-set of transformation flags. This call is equivalent to png_read_info(),
-followed the set of transformations indicated by the transform mask,
-then png_read_image(), and finally png_read_end().
-
-(The final parameter of this call is not yet used. Someday it might point
-to transformation parameters required by some future input transform.)
-
-You must use png_transforms and not call any png_set_transform() functions
-when you use png_read_png().
-
-After you have called png_read_png(), you can retrieve the image data
-with
-
- row_pointers = png_get_rows(png_ptr, info_ptr);
-
-where row_pointers is an array of pointers to the pixel data for each row:
-
- png_bytep row_pointers[height];
-
-If you know your image size and pixel size ahead of time, you can allocate
-row_pointers prior to calling png_read_png() with
-
- if (height > PNG_UINT_32_MAX/png_sizeof(png_byte))
- png_error (png_ptr,
- "Image is too tall to process in memory");
- if (width > PNG_UINT_32_MAX/pixel_size)
- png_error (png_ptr,
- "Image is too wide to process in memory");
- row_pointers = png_malloc(png_ptr,
- height*png_sizeof(png_bytep));
- for (int i=0; i<height, i++)
- row_pointers[i]=NULL; /* security precaution */
- for (int i=0; i<height, i++)
- row_pointers[i]=png_malloc(png_ptr,
- width*pixel_size);
- png_set_rows(png_ptr, info_ptr, &row_pointers);
-
-Alternatively you could allocate your image in one big block and define
-row_pointers[i] to point into the proper places in your block.
-
-If you use png_set_rows(), the application is responsible for freeing
-row_pointers (and row_pointers[i], if they were separately allocated).
-
-If you don't allocate row_pointers ahead of time, png_read_png() will
-do it, and it'll be free'ed when you call png_destroy_*().
-
-.SS The low-level read interface
-
-If you are going the low-level route, you are now ready to read all
-the file information up to the actual image data. You do this with a
-call to png_read_info().
-
- png_read_info(png_ptr, info_ptr);
-
-This will process all chunks up to but not including the image data.
-
-.SS Querying the info structure
-
-Functions are used to get the information from the info_ptr once it
-has been read. Note that these fields may not be completely filled
-in until png_read_end() has read the chunk data following the image.
-
- png_get_IHDR(png_ptr, info_ptr, &width, &height,
- &bit_depth, &color_type, &interlace_type,
- &compression_type, &filter_method);
-
- width - holds the width of the image
- in pixels (up to 2^31).
- height - holds the height of the image
- in pixels (up to 2^31).
- bit_depth - holds the bit depth of one of the
- image channels. (valid values are
- 1, 2, 4, 8, 16 and depend also on
- the color_type. See also
- significant bits (sBIT) below).
- color_type - describes which color/alpha channels
- are present.
- PNG_COLOR_TYPE_GRAY
- (bit depths 1, 2, 4, 8, 16)
- PNG_COLOR_TYPE_GRAY_ALPHA
- (bit depths 8, 16)
- PNG_COLOR_TYPE_PALETTE
- (bit depths 1, 2, 4, 8)

- PNG_COLOR_TYPE_RGB_ALPHA
- (bit_depths 8, 16)
-
- PNG_COLOR_MASK_PALETTE
- PNG_COLOR_MASK_COLOR
- PNG_COLOR_MASK_ALPHA
-
- interlace_type - (PNG_INTERLACE_NONE or
- PNG_INTERLACE_ADAM7)
-
- compression_type - (must be PNG_COMPRESSION_TYPE_BASE
- for PNG 1.0)
-
- filter_method - (must be PNG_FILTER_TYPE_BASE
- for PNG 1.0, and can also be
- PNG_INTRAPIXEL_DIFFERENCING if
- the PNG datastream is embedded in
- a MNG-1.0 datastream)
-
- Any or all of interlace_type, compression_type, or
- filter_method can be NULL if you are
- not interested in their values.
-
- Note that png_get_IHDR() returns 32-bit data into
- the application's width and height variables.
- This is an unsafe situation if these are 16-bit
- variables. In such situations, the
- png_get_image_width() and png_get_image_height()
- functions described below are safer.
-
- width = png_get_image_width(png_ptr,
- info_ptr);
- height = png_get_image_height(png_ptr,
- info_ptr);
- bit_depth = png_get_bit_depth(png_ptr,
- info_ptr);
- color_type = png_get_color_type(png_ptr,
- info_ptr);
- interlace_type = png_get_interlace_type(png_ptr,
- info_ptr);
- compression_type = png_get_compression_type(png_ptr,
- info_ptr);
- filter_method = png_get_filter_type(png_ptr,
- info_ptr);
-
- channels = png_get_channels(png_ptr, info_ptr);
- channels - number of channels of info for the
- color type (valid values are 1 (GRAY,
- PALETTE), 2 (GRAY_ALPHA), 3 (RGB),
- 4 (RGB_ALPHA or RGB + filler byte))
- rowbytes = png_get_rowbytes(png_ptr, info_ptr);
- rowbytes - number of bytes needed to hold a row
-
- signature = png_get_signature(png_ptr, info_ptr);
- signature - holds the signature read from the
- file (if any). The data is kept in
- the same offset it would be if the
- whole signature were read (i.e. if an
- application had already read in 4
- bytes of signature before starting
- libpng, the remaining 4 bytes would
- be in signature[4] through signature[7]
- (see png_set_sig_bytes())).
-
-These are also important, but their validity depends on whether the chunk
-has been read. The png_get_valid(png_ptr, info_ptr, PNG_INFO_<chunk>) and
-png_get_<chunk>(png_ptr, info_ptr, ...) functions return non-zero if the
-data has been read, or zero if it is missing. The parameters to the
-png_get_<chunk> are set directly if they are simple data types, or a
-pointer into the info_ptr is returned for any complex types.

- gamma - the gamma the file is written
- at (PNG_INFO_gAMA)
-
- png_get_sRGB(png_ptr, info_ptr, &srgb_intent);
- srgb_intent - the rendering intent (PNG_INFO_sRGB)
- The presence of the sRGB chunk
- means that the pixel data is in the
- sRGB color space. This chunk also
- implies specific values of gAMA and
- cHRM.
-
- png_get_iCCP(png_ptr, info_ptr, &name,
- &compression_type, &profile, &proflen);
- name - The profile name.
- compression_type - The compression type; always
- PNG_COMPRESSION_TYPE_BASE for PNG 1.0.
- You may give NULL to this argument to
- ignore it.
- profile - International Color Consortium color
- profile data. May contain NULs.
- proflen - length of profile data in bytes.
-
- png_get_sBIT(png_ptr, info_ptr, &sig_bit);
- sig_bit - the number of significant bits for

- when the library is built with iTXt chunk support.
-
- num_text - number of comments (same as
- num_comments; you can put NULL here
- to avoid the duplication)
- Note while png_set_text() will accept text, language,
- and translated keywords that can be NULL pointers, the

- res_x = png_get_x_pixels_per_inch(png_ptr,
- info_ptr)
- res_y = png_get_y_pixels_per_inch(png_ptr,

- res_x_and_y = png_get_pixels_per_inch(png_ptr,
- info_ptr)
- aspect_ratio = png_get_pixel_aspect_ratio(png_ptr,

-
- (Each of these returns 0 [signifying "unknown"] if
- the data is not present or if res_x is 0;
- res_x_and_y is 0 if res_x != res_y)
-
-The data from the oFFs chunk can be retrieved in several convenient
-forms:
-
- x_offset = png_get_x_offset_microns(png_ptr, info_ptr);
- y_offset = png_get_y_offset_microns(png_ptr, info_ptr);
- x_offset = png_get_x_offset_inches(png_ptr, info_ptr);
- y_offset = png_get_y_offset_inches(png_ptr, info_ptr);
-
- (Each of these returns 0 [signifying "unknown" if both
- x and y are 0] if the data is not present or if the
- chunk is present but the unit is the pixel)
-
-For more information, see the png_info definition in png.h and the
-PNG specification for chunk contents. Be careful with trusting
-rowbytes, as some of the transformations could increase the space
-needed to hold a row (expand, filler, gray_to_rgb, etc.).
-See png_read_update_info(), below.
-
-A quick word about text_ptr and num_text. PNG stores comments in
-keyword/text pairs, one pair per chunk, with no limit on the number
-of text chunks, and a 2^31 byte limit on their size. While there are
-suggested keywords, there is no requirement to restrict the use to these
-strings. It is strongly suggested that keywords and text be sensible
-to humans (that's the point), so don't use abbreviations. Non-printing
-symbols are not allowed. See the PNG specification for more details.
-There is also no requirement to have text after the keyword.
-
-Keywords should be limited to 79 Latin-1 characters without leading or
-trailing spaces, but non-consecutive spaces are allowed within the
-keyword. It is possible to have the same keyword any number of times.
-The text_ptr is an array of png_text structures, each holding a
-pointer to a language string, a pointer to a keyword and a pointer to
-a text string. The text string, language code, and translated
-keyword may be empty or NULL pointers. The keyword/text
-pairs are put into the array in the order that they are received.
-However, some or all of the text chunks may be after the image, so, to
-make sure you have read all the text chunks, don't mess with these
-until after you read the stuff after the image. This will be
-mentioned again below in the discussion that goes with png_read_end().
-
-.SS Input transformations
-
-After you've read the header information, you can set up the library
-to handle any special transformations of the image data. The various
-ways to transform the data will be described in the order that they
-should occur. This is important, as some of these change the color
-type and/or bit depth of the data, and some others only work on
-certain color types and bit depths. Even though each transformation
-checks to see if it has data that it can do something with, you should
-make sure to only enable a transformation if it will be valid for the
-data. For example, don't swap red and blue on grayscale data.
-
-The colors used for the background and transparency values should be
-supplied in the same format/depth as the current image data. They
-are stored in the same format/depth as the image data in a bKGD or tRNS
-chunk, so this is what libpng expects for this data. The colors are
-transformed to keep in sync with the image data when an application
-calls the png_read_update_info() routine (see below).
-
-Data will be decoded into the supplied row buffers packed into bytes
-unless the library has been told to transform it into another format.
-For example, 4 bit/pixel paletted or grayscale data will be returned
-2 pixels/byte with the leftmost pixel in the high-order bits of the
-byte, unless png_set_packing() is called. 8-bit RGB data will be stored
-in RGB RGB RGB format unless png_set_filler() or png_set_add_alpha()
-is called to insert filler bytes, either before or after each RGB triplet.
-16-bit RGB data will be returned RRGGBB RRGGBB, with the most significant
-byte of the color value first, unless png_set_strip_16() is called to
-transform it to regular RGB RGB triplets, or png_set_filler() or
-png_set_add alpha() is called to insert filler bytes, either before or
-after each RRGGBB triplet. Similarly, 8-bit or 16-bit grayscale data can
-be modified with
-png_set_filler(), png_set_add_alpha(), or png_set_strip_16().
-
-The following code transforms grayscale images of less than 8 to 8 bits,
-changes paletted images to RGB, and adds a full alpha channel if there is
-transparency information in a tRNS chunk. This is most useful on
-grayscale images with bit depths of 2 or 4 or if there is a multiple-image
-viewing application that wishes to treat all images in the same way.
-
- if (color_type == PNG_COLOR_TYPE_PALETTE)
- png_set_palette_to_rgb(png_ptr);
-
- if (color_type == PNG_COLOR_TYPE_GRAY &&
- bit_depth < 8) png_set_expand_gray_1_2_4_to_8(png_ptr);
-
- if (png_get_valid(png_ptr, info_ptr,
- PNG_INFO_tRNS)) png_set_tRNS_to_alpha(png_ptr);
-
-These three functions are actually aliases for png_set_expand(), added
-in libpng version 1.0.4, with the function names expanded to improve code
-readability. In some future version they may actually do different
-things.
-
-As of libpng version 1.2.9, png_set_expand_gray_1_2_4_to_8() was
-added. It expands the sample depth without changing tRNS to alpha.
-
-As of libpng version 1.4.12, not all possible expansions are supported.
-
-In the following table, the 01 means grayscale with depth<8, 31 means
-indexed with depth<8, other numerals represent the color type, "T" means
-the tRNS chunk is present, A means an alpha channel is present, and O
-means tRNS or alpha is present but all pixels in the image are opaque.

-
-PNG can have files with 16 bits per channel. If you only can handle
-8 bits per channel, this will strip the pixels down to 8 bit.
-
- if (bit_depth == 16)
- png_set_strip_16(png_ptr);
-
-If, for some reason, you don't need the alpha channel on an image,
-and you want to remove it rather than combining it with the background
-(but the image author certainly had in mind that you *would* combine
-it with the background, so that's what you should probably do):
-
- if (color_type & PNG_COLOR_MASK_ALPHA)
- png_set_strip_alpha(png_ptr);
-
-In PNG files, the alpha channel in an image
-is the level of opacity. If you need the alpha channel in an image to
-be the level of transparency instead of opacity, you can invert the
-alpha channel (or the tRNS chunk data) after it's read, so that 0 is
-fully opaque and 255 (in 8-bit or paletted images) or 65535 (in 16-bit
-images) is fully transparent, with
-
- png_set_invert_alpha(png_ptr);
-
-PNG files pack pixels of bit depths 1, 2, and 4 into bytes as small as
-they can, resulting in, for example, 8 pixels per byte for 1 bit
-files. This code expands to 1 pixel per byte without changing the
-values of the pixels:
-
- if (bit_depth < 8)
- png_set_packing(png_ptr);
-
-PNG files have possible bit depths of 1, 2, 4, 8, and 16. All pixels
-stored in a PNG image have been "scaled" or "shifted" up to the next
-higher possible bit depth (e.g. from 5 bits/sample in the range [0,31]
-to 8 bits/sample in the range [0, 255]). However, it is also possible
-to convert the PNG pixel data back to the original bit depth of the
-image. This call reduces the pixels back down to the original bit depth:
-
- png_color_8p sig_bit;
-
- if (png_get_sBIT(png_ptr, info_ptr, &sig_bit))
- png_set_shift(png_ptr, sig_bit);
-
-PNG files store 3-color pixels in red, green, blue order. This code
-changes the storage of the pixels to blue, green, red:
-
- if (color_type == PNG_COLOR_TYPE_RGB ||
- color_type == PNG_COLOR_TYPE_RGB_ALPHA)
- png_set_bgr(png_ptr);
-
-PNG files store RGB pixels packed into 3 or 6 bytes. This code expands them
-into 4 or 8 bytes for windowing systems that need them in this format:
-
- if (color_type == PNG_COLOR_TYPE_RGB)
- png_set_filler(png_ptr, filler, PNG_FILLER_BEFORE);
-
-where "filler" is the 8 or 16-bit number to fill with, and the location is
-either PNG_FILLER_BEFORE or PNG_FILLER_AFTER, depending upon whether
-you want the filler before the RGB or after. This transformation
-does not affect images that already have full alpha channels. To add an
-opaque alpha channel, use filler=0xff or 0xffff and PNG_FILLER_AFTER which
-will generate RGBA pixels.
-
-Note that png_set_filler() does not change the color type. If you want
-to do that, you can add a true alpha channel with
-
- if (color_type == PNG_COLOR_TYPE_RGB ||
- color_type == PNG_COLOR_TYPE_GRAY)
- png_set_add_alpha(png_ptr, filler, PNG_FILLER_AFTER);
-
-where "filler" contains the alpha value to assign to each pixel.
-This function was added in libpng-1.2.7.
-
-If you are reading an image with an alpha channel, and you need the
-data as ARGB instead of the normal PNG format RGBA:
-
- if (color_type == PNG_COLOR_TYPE_RGB_ALPHA)
- png_set_swap_alpha(png_ptr);
-
-For some uses, you may want a grayscale image to be represented as
-RGB. This code will do that conversion:
-
- if (color_type == PNG_COLOR_TYPE_GRAY ||
- color_type == PNG_COLOR_TYPE_GRAY_ALPHA)
- png_set_gray_to_rgb(png_ptr);
-
-Conversely, you can convert an RGB or RGBA image to grayscale or grayscale
-with alpha.
-
- if (color_type == PNG_COLOR_TYPE_RGB ||
- color_type == PNG_COLOR_TYPE_RGB_ALPHA)
- png_set_rgb_to_gray_fixed(png_ptr, error_action,
- int red_weight, int green_weight);
-
- error_action = 1: silently do the conversion
- error_action = 2: issue a warning if the original
- image has any pixel where
- red != green or red != blue
- error_action = 3: issue an error and abort the
- conversion if the original
- image has any pixel where
- red != green or red != blue
-
- red_weight: weight of red component times 100000
- green_weight: weight of green component times 100000
- If either weight is negative, default
- weights (21268, 71514) are used.
-
-If you have set error_action = 1 or 2, you can
-later check whether the image really was gray, after processing
-the image rows, with the png_get_rgb_to_gray_status(png_ptr) function.
-It will return a png_byte that is zero if the image was gray or
-1 if there were any non-gray pixels. bKGD and sBIT data
-will be silently converted to grayscale, using the green channel
-data, regardless of the error_action setting.
-
-With red_weight+green_weight<=100000,
-the normalized graylevel is computed:
-
- int rw = red_weight * 65536;
- int gw = green_weight * 65536;
- int bw = 65536 - (rw + gw);
- gray = (rw*red + gw*green + bw*blue)/65536;

-
- Y = 0.212671 * R + 0.715160 * G + 0.072169 * B
-
-Libpng approximates this with
-
- Y = 0.21268 * R + 0.7151 * G + 0.07217 * B
-
-which can be expressed with integers as
-
- Y = (6969 * R + 23434 * G + 2365 * B)/32768
-
-The calculation is done in a linear colorspace, if the image gamma
-is known.
-
-If you have a grayscale and you are using png_set_expand_depth(),
-png_set_expand(), or png_set_gray_to_rgb to change to truecolor or to
-a higher bit-depth, you must either supply the background color as a gray
-value at the original file bit-depth (need_expand = 1) or else supply the
-background color as an RGB triplet at the final, expanded bit depth
-(need_expand = 0). Similarly, if you are reading a paletted image, you
-must either supply the background color as a palette index (need_expand = 1)
-or as an RGB triplet that may or may not be in the palette (need_expand = 0).

- else
- png_set_background(png_ptr, &my_background,
- PNG_BACKGROUND_GAMMA_SCREEN, 0, 1.0);
-
-The png_set_background() function tells libpng to composite images
-with alpha or simple transparency against the supplied background
-color. If the PNG file contains a bKGD chunk (PNG_INFO_bKGD valid),
-you may use this color, or supply another color more suitable for
-the current display (e.g., the background color from a web page). You
-need to tell libpng whether the color is in the gamma space of the
-display (PNG_BACKGROUND_GAMMA_SCREEN for colors you supply), the file
-(PNG_BACKGROUND_GAMMA_FILE for colors from the bKGD chunk), or one
-that is neither of these gammas (PNG_BACKGROUND_GAMMA_UNIQUE - I don't
-know why anyone would use this, but it's here).
-
-To properly display PNG images on any kind of system, the application needs
-to know what the display gamma is. Ideally, the user will know this, and
-the application will allow them to set it. One method of allowing the user
-to set the display gamma separately for each system is to check for a
-SCREEN_GAMMA or DISPLAY_GAMMA environment variable, which will hopefully be
-correctly set.
-
-Note that display_gamma is the overall gamma correction required to produce
-pleasing results, which depends on the lighting conditions in the surrounding
-environment. In a dim or brightly lit room, no compensation other than
-the physical gamma exponent of the monitor is needed, while in a dark room
-a slightly smaller exponent is better.
-
- double gamma, screen_gamma;
-
- if (/* We have a user-defined screen
- gamma value */)

- screen_gamma = 2.0; /* A good guess for a
- PC monitor in a dark room */
- screen_gamma = 1.7 or 1.0; /* A good
- guess for Mac systems */
- }
-
-The png_set_gamma() function handles gamma transformations of the data.
-Pass both the file gamma and the current screen_gamma. If the file does
-not have a gamma value, you can pass one anyway if you have an idea what
-it is (usually 0.45455 is a good guess for GIF images on PCs). Note
-that file gammas are inverted from screen gammas. See the discussions
-on gamma in the PNG specification for an excellent description of what
-gamma is, and why all applications should support it. It is strongly
-recommended that PNG viewers support gamma correction.
-

- png_set_gamma(png_ptr, screen_gamma, gamma);
- else
- png_set_gamma(png_ptr, screen_gamma, 0.45455);
-
-If you need to reduce an RGB file to a paletted file, or if a paletted
-file has more entries then will fit on your screen, png_set_quantize()
-will do that. Note that this is a simple match dither that merely
-finds the closest color available. This should work fairly well with
-optimized palettes, and fairly badly with linear color cubes. If you
-pass a palette that is larger then maximum_colors, the file will
-reduce the number of colors in the palette so it will fit into
-maximum_colors. If there is a histogram, it will use it to make
-more intelligent choices when reducing the palette. If there is no
-histogram, it may not do as good a job.
-
- if (color_type & PNG_COLOR_MASK_COLOR)
- {
- if (png_get_valid(png_ptr, info_ptr,

-
-PNG files describe monochrome as black being zero and white being one.
-The following code will reverse this (make black be one and white be
-zero):
-
- if (bit_depth == 1 && color_type == PNG_COLOR_TYPE_GRAY)
- png_set_invert_mono(png_ptr);
-
-This function can also be used to invert grayscale and gray-alpha images:
-
- if (color_type == PNG_COLOR_TYPE_GRAY ||
- color_type == PNG_COLOR_TYPE_GRAY_ALPHA)
- png_set_invert_mono(png_ptr);
-
-PNG files store 16 bit pixels in network byte order (big-endian,
-ie. most significant bits first). This code changes the storage to the
-other way (little-endian, i.e. least significant bits first, the
-way PCs store them):
-
- if (bit_depth == 16)
- png_set_swap(png_ptr);
-
-If you are using packed-pixel images (1, 2, or 4 bits/pixel), and you
-need to change the order the pixels are packed into bytes, you can use:
-
- if (bit_depth < 8)
- png_set_packswap(png_ptr);
-
-Finally, you can write your own transformation function if none of
-the existing ones meets your needs. This is done by setting a callback
-with
-
- png_set_read_user_transform_fn(png_ptr,
- read_transform_fn);
-
-You must supply the function
-
- void read_transform_fn(png_structp png_ptr, png_row_infop
- row_info, png_bytep data)
-
-See pngtest.c for a working example. Your function will be called
-after all of the other transformations have been processed.
-
-You can also set up a pointer to a user structure for use by your
-callback function, and you can inform libpng that your transform
-function will change the number of channels or bit depth with the
-function
-
- png_set_user_transform_info(png_ptr, user_ptr,
- user_depth, user_channels);
-
-The user's application, not libpng, is responsible for allocating and
-freeing any memory required for the user structure.
-
-You can retrieve the pointer via the function
-png_get_user_transform_ptr(). For example:
-
- voidp read_user_transform_ptr =
- png_get_user_transform_ptr(png_ptr);
-
-The last thing to handle is interlacing; this is covered in detail below,
-but you must call the function here if you want libpng to handle expansion
-of the interlaced image.
-
- number_of_passes = png_set_interlace_handling(png_ptr);
-
-After setting the transformations, libpng can update your png_info
-structure to reflect any transformations you've requested with this
-call. This is most useful to update the info structure's rowbytes
-field so you can use it to allocate your image memory. This function
-will also update your palette with the correct screen_gamma and
-background if these have been given with the calls above.
-
- png_read_update_info(png_ptr, info_ptr);
-
-After you call png_read_update_info(), you can allocate any
-memory you need to hold the image. The row data is simply
-raw byte data for all forms of images. As the actual allocation
-varies among applications, no example will be given. If you
-are allocating one large chunk, you will need to build an
-array of pointers to each row, as it will be needed for some
-of the functions below.
-
-.SS Reading image data
-
-After you've allocated memory, you can read the image data.
-The simplest way to do this is in one function call. If you are
-allocating enough memory to hold the whole image, you can just
-call png_read_image() and libpng will read in all the image data
-and put it in the memory area supplied. You will need to pass in
-an array of pointers to each row.
-
-This function automatically handles interlacing, so you don't need
-to call png_set_interlace_handling() or call this function multiple
-times, or any of that other stuff necessary with png_read_rows().
-
- png_read_image(png_ptr, row_pointers);
-
-where row_pointers is:
-
- png_bytep row_pointers[height];
-
-You can point to void or char or whatever you use for pixels.
-
-If you don't want to read in the whole image at once, you can
-use png_read_rows() instead. If there is no interlacing (check
-interlace_type == PNG_INTERLACE_NONE), this is simple:
-
- png_read_rows(png_ptr, row_pointers, NULL,
- number_of_rows);
-
-where row_pointers is the same as in the png_read_image() call.
-
-If you are doing this just one row at a time, you can do this with
-a single row_pointer instead of an array of row_pointers:
-
- png_bytep row_pointer = row;
- png_read_row(png_ptr, row_pointer, NULL);
-
-If the file is interlaced (interlace_type != 0 in the IHDR chunk), things
-get somewhat harder. The only current (PNG Specification version 1.2)
-interlacing type for PNG is (interlace_type == PNG_INTERLACE_ADAM7)
-is a somewhat complicated 2D interlace scheme, known as Adam7, that
-breaks down an image into seven smaller images of varying size, based
-on an 8x8 grid.
-
-libpng can fill out those images or it can give them to you "as is".
-If you want them filled out, there are two ways to do that. The one
-mentioned in the PNG specification is to expand each pixel to cover
-those pixels that have not been read yet (the "rectangle" method).
-This results in a blocky image for the first pass, which gradually
-smooths out as more pixels are read. The other method is the "sparkle"
-method, where pixels are drawn only in their final locations, with the
-rest of the image remaining whatever colors they were initialized to
-before the start of the read. The first method usually looks better,
-but tends to be slower, as there are more pixels to put in the rows.
-
-If you don't want libpng to handle the interlacing details, just call
-png_read_rows() seven times to read in all seven images. Each of the
-images is a valid image by itself, or they can all be combined on an
-8x8 grid to form a single image (although if you intend to combine them
-you would be far better off using the libpng interlace handling).
-
-The first pass will return an image 1/8 as wide as the entire image
-(every 8th column starting in column 0) and 1/8 as high as the original
-(every 8th row starting in row 0), the second will be 1/8 as wide
-(starting in column 4) and 1/8 as high (also starting in row 0). The
-third pass will be 1/4 as wide (every 4th pixel starting in column 0) and
-1/8 as high (every 8th row starting in row 4), and the fourth pass will
-be 1/4 as wide and 1/4 as high (every 4th column starting in column 2,
-and every 4th row starting in row 0). The fifth pass will return an
-image 1/2 as wide, and 1/4 as high (starting at column 0 and row 2),
-while the sixth pass will be 1/2 as wide and 1/2 as high as the original
-(starting in column 1 and row 0). The seventh and final pass will be as
-wide as the original, and 1/2 as high, containing all of the odd
-numbered scanlines. Phew!
-
-If you want libpng to expand the images, call this before calling
-png_start_read_image() or png_read_update_info():
-
- if (interlace_type == PNG_INTERLACE_ADAM7)
- number_of_passes
- = png_set_interlace_handling(png_ptr);
-
-This will return the number of passes needed. Currently, this
-is seven, but may change if another interlace type is added.
-This function can be called even if the file is not interlaced,
-where it will return one pass.
-
-If you are not going to display the image after each pass, but are
-going to wait until the entire image is read in, use the sparkle
-effect. This effect is faster and the end result of either method
-is exactly the same. If you are planning on displaying the image
-after each pass, the "rectangle" effect is generally considered the
-better looking one.
-
-If you only want the "sparkle" effect, just call png_read_rows() as
-normal, with the third parameter NULL. Make sure you make pass over
-the image number_of_passes times, and you don't change the data in the
-rows between calls. You can change the locations of the data, just
-not the data. Each pass only writes the pixels appropriate for that
-pass, and assumes the data from previous passes is still valid.
-
- png_read_rows(png_ptr, row_pointers, NULL,
- number_of_rows);
-
-If you only want the first effect (the rectangles), do the same as
-before except pass the row buffer in the third parameter, and leave
-the second parameter NULL.
-
- png_read_rows(png_ptr, NULL, row_pointers,
- number_of_rows);
-
-.SS Finishing a sequential read
-
-After you are finished reading the image through the
-low-level interface, you can finish reading the file. If you are
-interested in comments or time, which may be stored either before or
-after the image data, you should pass the separate png_info struct if
-you want to keep the comments from before and after the image
-separate. If you are not interested, you can pass NULL.
-
- png_read_end(png_ptr, end_info);
-
-When you are done, you can free all memory allocated by libpng like this:
-
- png_destroy_read_struct(&png_ptr, &info_ptr,
- &end_info);
-
-It is also possible to individually free the info_ptr members that
-point to libpng-allocated storage with the following function:
-
- png_free_data(png_ptr, info_ptr, mask, seq)
- mask - identifies data to be freed, a mask
- containing the bitwise OR of one or
- more of
- PNG_FREE_PLTE, PNG_FREE_TRNS,
- PNG_FREE_HIST, PNG_FREE_ICCP,
- PNG_FREE_PCAL, PNG_FREE_ROWS,
- PNG_FREE_SCAL, PNG_FREE_SPLT,
- PNG_FREE_TEXT, PNG_FREE_UNKN,
- or simply PNG_FREE_ALL
- seq - sequence number of item to be freed
- (-1 for all items)
-
-This function may be safely called when the relevant storage has
-already been freed, or has not yet been allocated, or was allocated
-by the user and not by libpng, and will in those cases do nothing.
-The "seq" parameter is ignored if only one item of the selected data
-type, such as PLTE, is allowed. If "seq" is not -1, and multiple items
-are allowed for the data type identified in the mask, such as text or
-sPLT, only the n'th item in the structure is freed, where n is "seq".
-
-The default behavior is only to free data that was allocated internally
-by libpng. This can be changed, so that libpng will not free the data,
-or so that it will free data that was allocated by the user with png_malloc()
-or png_zalloc() and passed in via a png_set_*() function, with
-
- png_data_freer(png_ptr, info_ptr, freer, mask)
- mask - which data elements are affected
- same choices as in png_free_data()
- freer - one of
- PNG_DESTROY_WILL_FREE_DATA
- PNG_SET_WILL_FREE_DATA
- PNG_USER_WILL_FREE_DATA
-
-This function only affects data that has already been allocated.
-You can call this function after reading the PNG data but before calling
-any png_set_*() functions, to control whether the user or the png_set_*()
-function is responsible for freeing any existing data that might be present,
-and again after the png_set_*() functions to control whether the user
-or png_destroy_*() is supposed to free the data. When the user assumes
-responsibility for libpng-allocated data, the application must use
-png_free() to free it, and when the user transfers responsibility to libpng
-for data that the user has allocated, the user must have used png_malloc()
-or png_zalloc() to allocate it.
-
-If you allocated your row_pointers in a single block, as suggested above in
-the description of the high level read interface, you must not transfer
-responsibility for freeing it to the png_set_rows or png_read_destroy function,
-because they would also try to free the individual row_pointers[i].
-
-If you allocated text_ptr.text, text_ptr.lang, and text_ptr.translated_keyword
-separately, do not transfer responsibility for freeing text_ptr to libpng,
-because when libpng fills a png_text structure it combines these members with
-the key member, and png_free_data() will free only text_ptr.key. Similarly,
-if you transfer responsibility for free'ing text_ptr from libpng to your
-application, your application must not separately free those members.
-
-The png_free_data() function will turn off the "valid" flag for anything
-it frees. If you need to turn the flag off for a chunk that was freed by
-your application instead of by libpng, you can use
-
- png_set_invalid(png_ptr, info_ptr, mask);
- mask - identifies the chunks to be made invalid,
- containing the bitwise OR of one or
- more of
- PNG_INFO_gAMA, PNG_INFO_sBIT,
- PNG_INFO_cHRM, PNG_INFO_PLTE,
- PNG_INFO_tRNS, PNG_INFO_bKGD,
- PNG_INFO_hIST, PNG_INFO_pHYs,
- PNG_INFO_oFFs, PNG_INFO_tIME,
- PNG_INFO_pCAL, PNG_INFO_sRGB,
- PNG_INFO_iCCP, PNG_INFO_sPLT,
- PNG_INFO_sCAL, PNG_INFO_IDAT
-
-For a more compact example of reading a PNG image, see the file example.c.
-
-.SS Reading PNG files progressively
-
-The progressive reader is slightly different then the non-progressive
-reader. Instead of calling png_read_info(), png_read_rows(), and
-png_read_end(), you make one call to png_process_data(), which calls
-callbacks when it has the info, a row, or the end of the image. You
-set up these callbacks with png_set_progressive_read_fn(). You don't
-have to worry about the input/output functions of libpng, as you are
-giving the library the data directly in png_process_data(). I will
-assume that you have read the section on reading PNG files above,
-so I will only highlight the differences (although I will show
-all of the code).

-
-.SH IV. Writing
-
-Much of this is very similar to reading. However, everything of
-importance is repeated here, so you won't have to constantly look
-back up in the reading section to understand writing.
-
-.SS Setup
-
-You will want to do the I/O initialization before you get into libpng,
-so if it doesn't work, you don't have anything to undo. If you are not
-using the standard I/O functions, you will need to replace them with
-custom writing functions. See the discussion under Customizing libpng.
-
- FILE *fp = fopen(file_name, "wb");
- if (!fp)
- {
- return (ERROR);
- }
-
-Next, png_struct and png_info need to be allocated and initialized.
-As these can be both relatively large, you may not want to store these
-on the stack, unless you have stack space to spare. Of course, you
-will want to check if they return NULL. If you are also reading,
-you won't want to name your read structure and your write structure
-both "png_ptr"; you can call them anything you like, such as
-"read_ptr" and "write_ptr". Look at pngtest.c, for example.
-
- png_structp png_ptr = png_create_write_struct
- (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
- user_error_fn, user_warning_fn);
- if (!png_ptr)
- return (ERROR);
-
- png_infop info_ptr = png_create_info_struct(png_ptr);
- if (!info_ptr)
- {
- png_destroy_write_struct(&png_ptr,
- (png_infopp)NULL);
- return (ERROR);
- }
-
-If you want to use your own memory allocation routines,
-define PNG_USER_MEM_SUPPORTED and use
-png_create_write_struct_2() instead of png_create_write_struct():
-
- png_structp png_ptr = png_create_write_struct_2
- (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr,
- user_error_fn, user_warning_fn, (png_voidp)
- user_mem_ptr, user_malloc_fn, user_free_fn);
-
-After you have these structures, you will need to set up the
-error handling. When libpng encounters an error, it expects to
-longjmp() back to your routine. Therefore, you will need to call
-setjmp() and pass the png_jmpbuf(png_ptr). If you
-write the file from different routines, you will need to update
-the png_jmpbuf(png_ptr) every time you enter a new routine that will
-call a png_*() function. See your documentation of setjmp/longjmp
-for your compiler for more information on setjmp/longjmp. See
-the discussion on libpng error handling in the Customizing Libpng
-section below for more information on the libpng error handling.
-
- if (setjmp(png_jmpbuf(png_ptr)))
- {
- png_destroy_write_struct(&png_ptr, &info_ptr);
- fclose(fp);
- return (ERROR);
- }
- ...
- return;
-
-If you would rather avoid the complexity of setjmp/longjmp issues,
-you can compile libpng with PNG_NO_SETJMP, in which case
-errors will result in a call to PNG_ABORT() which defaults to abort().
-
-You can #define PNG_ABORT() to a function that does something
-more useful than abort(), as long as your function does not
-return.
-
-Now you need to set up the output code. The default for libpng is to
-use the C function fwrite(). If you use this, you will need to pass a
-valid FILE * in the function png_init_io(). Be sure that the file is
-opened in binary mode. Again, if you wish to handle writing data in
-another way, see the discussion on libpng I/O handling in the Customizing
-Libpng section below.
-
- png_init_io(png_ptr, fp);
-
-If you are embedding your PNG into a datastream such as MNG, and don't
-want libpng to write the 8-byte signature, or if you have already
-written the signature in your application, use
-
- png_set_sig_bytes(png_ptr, 8);
-
-to inform libpng that it should not write a signature.
-
-.SS Write callbacks
-
-At this point, you can set up a callback function that will be
-called after each row has been written, which you can use to control
-a progress meter or the like. It's demonstrated in pngtest.c.
-You must supply a function
-
- void write_row_callback(png_structp png_ptr, png_uint_32 row,
- int pass);
- {
- /* put your code here */
- }
-
-(You can give it another name that you like instead of "write_row_callback")
-
-To inform libpng about your function, use
-
- png_set_write_status_fn(png_ptr, write_row_callback);
-
-You now have the option of modifying how the compression library will
-run. The following functions are mainly for testing, but may be useful
-in some cases, like if you need to write PNG files extremely fast and
-are willing to give up some compression, or if you want to get the
-maximum possible compression at the expense of slower writing. If you
-have no special needs in this area, let the library do what it wants by
-not calling this function at all, as it has been tuned to deliver a good
-speed/compression ratio. The second parameter to png_set_filter() is
-the filter method, for which the only valid values are 0 (as of the
-July 1999 PNG specification, version 1.2) or 64 (if you are writing
-a PNG datastream that is to be embedded in a MNG datastream). The third
-parameter is a flag that indicates which filter type(s) are to be tested
-for each scanline. See the PNG specification for details on the specific
-filter types.
-
-
- /* turn on or off filtering, and/or choose
- specific filters. You can use either a single
- PNG_FILTER_VALUE_NAME or the bitwise OR of one
- or more PNG_FILTER_NAME masks. */
- png_set_filter(png_ptr, 0,
- PNG_FILTER_NONE | PNG_FILTER_VALUE_NONE |
- PNG_FILTER_SUB | PNG_FILTER_VALUE_SUB |
- PNG_FILTER_UP | PNG_FILTER_VALUE_UP |
- PNG_FILTER_AVG | PNG_FILTER_VALUE_AVG |
- PNG_FILTER_PAETH | PNG_FILTER_VALUE_PAETH|
- PNG_ALL_FILTERS);
-
-If an application
-wants to start and stop using particular filters during compression,
-it should start out with all of the filters (to ensure that the previous
-row of pixels will be stored in case it's needed later), and then add
-and remove them after the start of compression.
-
-If you are writing a PNG datastream that is to be embedded in a MNG
-datastream, the second parameter can be either 0 or 64.
-
-The png_set_compression_*() functions interface to the zlib compression
-library, and should mostly be ignored unless you really know what you are
-doing. The only generally useful call is png_set_compression_level()
-which changes how much time zlib spends on trying to compress the image
-data. See the Compression Library (zlib.h and algorithm.txt, distributed
-with zlib) for details on the compression levels.
-
- /* set the zlib compression level */
- png_set_compression_level(png_ptr,
- Z_BEST_COMPRESSION);
-
- /* set other zlib parameters */
- png_set_compression_mem_level(png_ptr, 8);
- png_set_compression_strategy(png_ptr,
- Z_DEFAULT_STRATEGY);
- png_set_compression_window_bits(png_ptr, 15);
- png_set_compression_method(png_ptr, 8);
- png_set_compression_buffer_size(png_ptr, 8192)
-
-extern PNG_EXPORT(void,png_set_zbuf_size)
-
-.SS Setting the contents of info for output
-
-You now need to fill in the png_info structure with all the data you
-wish to write before the actual image. Note that the only thing you
-are allowed to write after the image is the text chunks and the time
-chunk (as of PNG Specification 1.2, anyway). See png_write_end() and
-the latest PNG specification for more information on that. If you
-wish to write them before the image, fill them in now, and flag that
-data as being valid. If you want to wait until after the data, don't
-fill them until png_write_end(). For all the fields in png_info and
-their data types, see png.h. For explanations of what the fields
-contain, see the PNG specification.
-
-Some of the more important parts of the png_info are:
-
- png_set_IHDR(png_ptr, info_ptr, width, height,
- bit_depth, color_type, interlace_type,
- compression_type, filter_method)
- width - holds the width of the image
- in pixels (up to 2^31).
- height - holds the height of the image
- in pixels (up to 2^31).
- bit_depth - holds the bit depth of one of the
- image channels.
- (valid values are 1, 2, 4, 8, 16
- and depend also on the
- color_type. See also significant
- bits (sBIT) below).
- color_type - describes which color/alpha
- channels are present.
- PNG_COLOR_TYPE_GRAY
- (bit depths 1, 2, 4, 8, 16)

- PNG_COLOR_MASK_ALPHA
-
- interlace_type - PNG_INTERLACE_NONE or
- PNG_INTERLACE_ADAM7
- compression_type - (must be
- PNG_COMPRESSION_TYPE_DEFAULT)
- filter_method - (must be PNG_FILTER_TYPE_DEFAULT
- or, if you are writing a PNG to
- be embedded in a MNG datastream,
- can also be
- PNG_INTRAPIXEL_DIFFERENCING)
-
-If you call png_set_IHDR(), the call must appear before any of the
-other png_set_*() functions, because they might require access to some of
-the IHDR settings. The remaining png_set_*() functions can be called
-in any order.
-
-If you wish, you can reset the compression_type, interlace_type, or
-filter_method later by calling png_set_IHDR() again; if you do this, the
-width, height, bit_depth, and color_type must be the same in each call.

- PNG_AFTER_IDAT: after IDAT
-
-The "location" member is set automatically according to
-what part of the output file has already been written.
-You can change its value after calling png_set_unknown_chunks()
-as demonstrated in pngtest.c. Within each of the "locations",
-the chunks are sequenced according to their position in the
-structure (that is, the value of "i", which is the order in which
-the chunk was either read from the input file or defined with
-png_set_unknown_chunks).
-
-A quick word about text and num_text. text is an array of png_text
-structures. num_text is the number of valid structures in the array.
-Each png_text structure holds a language code, a keyword, a text value,
-and a compression type.
-
-The compression types have the same valid numbers as the compression
-types of the image data. Currently, the only valid number is zero.
-However, you can store text either compressed or uncompressed, unlike
-images, which always have to be compressed. So if you don't want the
-text compressed, set the compression type to PNG_TEXT_COMPRESSION_NONE.
-Because tEXt and zTXt chunks don't have a language field, if you
-specify PNG_TEXT_COMPRESSION_NONE or PNG_TEXT_COMPRESSION_zTXt
-any language code or translated keyword will not be written out.
-
-Until text gets around 1000 bytes, it is not worth compressing it.
-After the text has been written out to the file, the compression type
-is set to PNG_TEXT_COMPRESSION_NONE_WR or PNG_TEXT_COMPRESSION_zTXt_WR,
-so that it isn't written out again at the end (in case you are calling
-png_write_end() with the same struct.
-
-The keywords that are given in the PNG Specification are:
-
- Title Short (one line) title or
- caption for image
- Author Name of image's creator
- Description Description of image (possibly long)
- Copyright Copyright notice
- Creation Time Time of original image creation
- (usually RFC 1123 format, see below)
- Software Software used to create the image
- Disclaimer Legal disclaimer
- Warning Warning of nature of content
- Source Device used to create the image
- Comment Miscellaneous comment; conversion
- from other image format
-
-The keyword-text pairs work like this. Keywords should be short
-simple descriptions of what the comment is about. Some typical
-keywords are found in the PNG specification, as is some recommendations
-on keywords. You can repeat keywords in a file. You can even write
-some text before the image and some after. For example, you may want
-to put a description of the image before the image, but leave the
-disclaimer until after, so viewers working over modem connections
-don't have to wait for the disclaimer to go over the modem before
-they start seeing the image. Finally, keywords should be full
-words, not abbreviations. Keywords and text are in the ISO 8859-1
-(Latin-1) character set (a superset of regular ASCII) and can not
-contain NUL characters, and should not contain control or other
-unprintable characters. To make the comments widely readable, stick
-with basic ASCII, and avoid machine specific character set extensions
-like the IBM-PC character set. The keyword must be present, but
-you can leave off the text string on non-compressed pairs.
-Compressed pairs must have a text string, as only the text string
-is compressed anyway, so the compression would be meaningless.
-
-PNG supports modification time via the png_time structure. Two
-conversion routines are provided, png_convert_from_time_t() for
-time_t and png_convert_from_struct_tm() for struct tm. The
-time_t routine uses gmtime(). You don't have to use either of
-these, but if you wish to fill in the png_time structure directly,
-you should provide the time in universal time (GMT) if possible
-instead of your local time. Note that the year number is the full
-year (e.g. 1998, rather than 98 - PNG is year 2000 compliant!), and
-that months start with 1.
-
-If you want to store the time of the original image creation, you should
-use a plain tEXt chunk with the "Creation Time" keyword. This is
-necessary because the "creation time" of a PNG image is somewhat vague,
-depending on whether you mean the PNG file, the time the image was
-created in a non-PNG format, a still photo from which the image was
-scanned, or possibly the subject matter itself. In order to facilitate
-machine-readable dates, it is recommended that the "Creation Time"
-tEXt chunk use RFC 1123 format dates (e.g. "22 May 1997 18:07:10 GMT"),
-although this isn't a requirement. Unlike the tIME chunk, the
-"Creation Time" tEXt chunk is not expected to be automatically changed
-by the software. To facilitate the use of RFC 1123 dates, a function
-png_convert_to_rfc1123(png_timep) is provided to convert from PNG
-time to an RFC 1123 format string.
-
-.SS Writing unknown chunks
-
-You can use the png_set_unknown_chunks function to queue up chunks
-for writing. You give it a chunk name, raw data, and a size; that's
-all there is to it. The chunks will be written by the next following
-png_write_info_before_PLTE, png_write_info, or png_write_end function.
-Any chunks previously read into the info structure's unknown-chunk
-list will also be written out in a sequence that satisfies the PNG
-specification's ordering rules.
-
-.SS The high-level write interface
-
-At this point there are two ways to proceed; through the high-level
-write interface, or through a sequence of low-level write operations.
-You can use the high-level interface if your image data is present
-in the info structure. All defined output
-transformations are permitted, enabled by the following masks.
-
- PNG_TRANSFORM_IDENTITY No transformation
- PNG_TRANSFORM_PACKING Pack 1, 2 and 4-bit samples
- PNG_TRANSFORM_PACKSWAP Change order of packed
- pixels to LSB first
- PNG_TRANSFORM_INVERT_MONO Invert monochrome images
- PNG_TRANSFORM_SHIFT Normalize pixels to the
- sBIT depth
- PNG_TRANSFORM_BGR Flip RGB to BGR, RGBA
- to BGRA
- PNG_TRANSFORM_SWAP_ALPHA Flip RGBA to ARGB or GA
- to AG
- PNG_TRANSFORM_INVERT_ALPHA Change alpha from opacity
- to transparency
- PNG_TRANSFORM_SWAP_ENDIAN Byte-swap 16-bit samples
- PNG_TRANSFORM_STRIP_FILLER Strip out filler
- bytes (deprecated).
- PNG_TRANSFORM_STRIP_FILLER_BEFORE Strip out leading
- filler bytes
- PNG_TRANSFORM_STRIP_FILLER_AFTER Strip out trailing
- filler bytes
-
-If you have valid image data in the info structure (you can use
-png_set_rows() to put image data in the info structure), simply do this:
-
- png_write_png(png_ptr, info_ptr, png_transforms, NULL)
-
-where png_transforms is an integer containing the bitwise OR of some set of
-transformation flags. This call is equivalent to png_write_info(),
-followed the set of transformations indicated by the transform mask,
-then png_write_image(), and finally png_write_end().
-
-(The final parameter of this call is not yet used. Someday it might point
-to transformation parameters required by some future output transform.)
-
-You must use png_transforms and not call any png_set_transform() functions
-when you use png_write_png().
-
-.SS The low-level write interface
-
-If you are going the low-level route instead, you are now ready to
-write all the file information up to the actual image data. You do
-this with a call to png_write_info().
-
- png_write_info(png_ptr, info_ptr);
-
-Note that there is one transformation you may need to do before
-png_write_info(). In PNG files, the alpha channel in an image is the
-level of opacity. If your data is supplied as a level of transparency,
-you can invert the alpha channel before you write it, so that 0 is
-fully transparent and 255 (in 8-bit or paletted images) or 65535
-(in 16-bit images) is fully opaque, with
-
- png_set_invert_alpha(png_ptr);
-
-This must appear before png_write_info() instead of later with the
-other transformations because in the case of paletted images the tRNS
-chunk data has to be inverted before the tRNS chunk is written. If
-your image is not a paletted image, the tRNS data (which in such cases
-represents a single color to be rendered as transparent) won't need to
-be changed, and you can safely do this transformation after your
-png_write_info() call.
-
-If you need to write a private chunk that you want to appear before
-the PLTE chunk when PLTE is present, you can write the PNG info in
-two steps, and insert code to write your own chunk between them:
-
- png_write_info_before_PLTE(png_ptr, info_ptr);
- png_set_unknown_chunks(png_ptr, info_ptr, ...);
- png_write_info(png_ptr, info_ptr);
-
-After you've written the file information, you can set up the library
-to handle any special transformations of the image data. The various
-ways to transform the data will be described in the order that they
-should occur. This is important, as some of these change the color
-type and/or bit depth of the data, and some others only work on
-certain color types and bit depths. Even though each transformation
-checks to see if it has data that it can do something with, you should
-make sure to only enable a transformation if it will be valid for the
-data. For example, don't swap red and blue on grayscale data.
-
-PNG files store RGB pixels packed into 3 or 6 bytes. This code tells
-the library to strip input data that has 4 or 8 bytes per pixel down
-to 3 or 6 bytes (or strip 2 or 4-byte grayscale+filler data to 1 or 2
-bytes per pixel).
-
- png_set_filler(png_ptr, 0, PNG_FILLER_BEFORE);
-
-where the 0 is unused, and the location is either PNG_FILLER_BEFORE or
-PNG_FILLER_AFTER, depending upon whether the filler byte in the pixel
-is stored XRGB or RGBX.
-
-PNG files pack pixels of bit depths 1, 2, and 4 into bytes as small as
-they can, resulting in, for example, 8 pixels per byte for 1 bit files.
-If the data is supplied at 1 pixel per byte, use this code, which will
-correctly pack the pixels into a single byte:
-
- png_set_packing(png_ptr);
-
-PNG files reduce possible bit depths to 1, 2, 4, 8, and 16. If your
-data is of another bit depth, you can write an sBIT chunk into the
-file so that decoders can recover the original data if desired.
-
- /* Set the true bit depth of the image data */
- if (color_type & PNG_COLOR_MASK_COLOR)
- {
- sig_bit.red = true_bit_depth;
- sig_bit.green = true_bit_depth;
- sig_bit.blue = true_bit_depth;
- }
- else
- {
- sig_bit.gray = true_bit_depth;
- }
- if (color_type & PNG_COLOR_MASK_ALPHA)
- {
- sig_bit.alpha = true_bit_depth;
- }
-
- png_set_sBIT(png_ptr, info_ptr, &sig_bit);
-
-If the data is stored in the row buffer in a bit depth other than
-one supported by PNG (e.g. 3 bit data in the range 0-7 for a 4-bit PNG),
-this will scale the values to appear to be the correct bit depth as
-is required by PNG.
-
- png_set_shift(png_ptr, &sig_bit);
-
-PNG files store 16 bit pixels in network byte order (big-endian,
-ie. most significant bits first). This code would be used if they are
-supplied the other way (little-endian, i.e. least significant bits
-first, the way PCs store them):
-
- if (bit_depth > 8)
- png_set_swap(png_ptr);
-
-If you are using packed-pixel images (1, 2, or 4 bits/pixel), and you
-need to change the order the pixels are packed into bytes, you can use:
-
- if (bit_depth < 8)
- png_set_packswap(png_ptr);
-
-PNG files store 3 color pixels in red, green, blue order. This code
-would be used if they are supplied as blue, green, red:
-
- png_set_bgr(png_ptr);
-
-PNG files describe monochrome as black being zero and white being
-one. This code would be used if the pixels are supplied with this reversed
-(black being one and white being zero):
-
- png_set_invert_mono(png_ptr);
-
-Finally, you can write your own transformation function if none of
-the existing ones meets your needs. This is done by setting a callback
-with
-
- png_set_write_user_transform_fn(png_ptr,
- write_transform_fn);
-
-You must supply the function
-
- void write_transform_fn(png_structp png_ptr, png_row_infop
- row_info, png_bytep data)
-
-See pngtest.c for a working example. Your function will be called
-before any of the other transformations are processed.
-
-You can also set up a pointer to a user structure for use by your
-callback function.
-
- png_set_user_transform_info(png_ptr, user_ptr, 0, 0);
-
-The user_channels and user_depth parameters of this function are ignored
-when writing; you can set them to zero as shown.
-
-You can retrieve the pointer via the function png_get_user_transform_ptr().
-For example:
-
- voidp write_user_transform_ptr =
- png_get_user_transform_ptr(png_ptr);
-
-It is possible to have libpng flush any pending output, either manually,
-or automatically after a certain number of lines have been written. To
-flush the output stream a single time call:
-
- png_write_flush(png_ptr);
-
-and to have libpng flush the output stream periodically after a certain
-number of scanlines have been written, call:
-
- png_set_flush(png_ptr, nrows);
-
-Note that the distance between rows is from the last time png_write_flush()
-was called, or the first row of the image if it has never been called.
-So if you write 50 lines, and then png_set_flush 25, it will flush the
-output on the next scanline, and every 25 lines thereafter, unless
-png_write_flush() is called before 25 more lines have been written.
-If nrows is too small (less than about 10 lines for a 640 pixel wide
-RGB image) the image compression may decrease noticeably (although this
-may be acceptable for real-time applications). Infrequent flushing will
-only degrade the compression performance by a few percent over images
-that do not use flushing.
-
-.SS Writing the image data
-
-That's it for the transformations. Now you can write the image data.
-The simplest way to do this is in one function call. If you have the
-whole image in memory, you can just call png_write_image() and libpng
-will write the image. You will need to pass in an array of pointers to
-each row. This function automatically handles interlacing, so you don't
-need to call png_set_interlace_handling() or call this function multiple
-times, or any of that other stuff necessary with png_write_rows().
-
- png_write_image(png_ptr, row_pointers);
-
-where row_pointers is:
-
- png_byte *row_pointers[height];
-
-You can point to void or char or whatever you use for pixels.
-
-If you don't want to write the whole image at once, you can
-use png_write_rows() instead. If the file is not interlaced,
-this is simple:
-
- png_write_rows(png_ptr, row_pointers,
- number_of_rows);
-
-row_pointers is the same as in the png_write_image() call.
-
-If you are just writing one row at a time, you can do this with
-a single row_pointer instead of an array of row_pointers:
-
- png_bytep row_pointer = row;
-
- png_write_row(png_ptr, row_pointer);
-
-When the file is interlaced, things can get a good deal more complicated.
-The only currently (as of the PNG Specification version 1.2, dated July
-1999) defined interlacing scheme for PNG files is the "Adam7" interlace
-scheme, that breaks down an image into seven smaller images of varying
-size. libpng will build these images for you, or you can do them
-yourself. If you want to build them yourself, see the PNG specification
-for details of which pixels to write when.
-
-If you don't want libpng to handle the interlacing details, just
-use png_set_interlace_handling() and call png_write_rows() the
-correct number of times to write all seven sub-images.
-
-If you want libpng to build the sub-images, call this before you start
-writing any rows:
-
- number_of_passes =
- png_set_interlace_handling(png_ptr);
-
-This will return the number of passes needed. Currently, this is seven,
-but may change if another interlace type is added.
-
-Then write the complete image number_of_passes times.
-
- png_write_rows(png_ptr, row_pointers,
- number_of_rows);
-
-As some of these rows are not used, and thus return immediately, you may
-want to read about interlacing in the PNG specification, and only update
-the rows that are actually used.
-
-.SS Finishing a sequential write
-
-After you are finished writing the image, you should finish writing
-the file. If you are interested in writing comments or time, you should
-pass an appropriately filled png_info pointer. If you are not interested,
-you can pass NULL.
-
- png_write_end(png_ptr, info_ptr);
-
-When you are done, you can free all memory used by libpng like this:
-
- png_destroy_write_struct(&png_ptr, &info_ptr);
-
-It is also possible to individually free the info_ptr members that
-point to libpng-allocated storage with the following function:
-
- png_free_data(png_ptr, info_ptr, mask, seq)
- mask - identifies data to be freed, a mask
- containing the bitwise OR of one or
- more of
- PNG_FREE_PLTE, PNG_FREE_TRNS,
- PNG_FREE_HIST, PNG_FREE_ICCP,
- PNG_FREE_PCAL, PNG_FREE_ROWS,
- PNG_FREE_SCAL, PNG_FREE_SPLT,
- PNG_FREE_TEXT, PNG_FREE_UNKN,
- or simply PNG_FREE_ALL
- seq - sequence number of item to be freed
- (-1 for all items)
-
-This function may be safely called when the relevant storage has
-already been freed, or has not yet been allocated, or was allocated
-by the user and not by libpng, and will in those cases do nothing.
-The "seq" parameter is ignored if only one item of the selected data
-type, such as PLTE, is allowed. If "seq" is not -1, and multiple items
-are allowed for the data type identified in the mask, such as text or
-sPLT, only the n'th item in the structure is freed, where n is "seq".
-
-If you allocated data such as a palette that you passed in to libpng
-with png_set_*, you must not free it until just before the call to
-png_destroy_write_struct().
-
-The default behavior is only to free data that was allocated internally
-by libpng. This can be changed, so that libpng will not free the data,
-or so that it will free data that was allocated by the user with png_malloc()
-or png_zalloc() and passed in via a png_set_*() function, with
-
- png_data_freer(png_ptr, info_ptr, freer, mask)
- mask - which data elements are affected
- same choices as in png_free_data()
- freer - one of
- PNG_DESTROY_WILL_FREE_DATA
- PNG_SET_WILL_FREE_DATA
- PNG_USER_WILL_FREE_DATA
-
-For example, to transfer responsibility for some data from a read structure
-to a write structure, you could use
-
- png_data_freer(read_ptr, read_info_ptr,
- PNG_USER_WILL_FREE_DATA,
- PNG_FREE_PLTE|PNG_FREE_tRNS|PNG_FREE_hIST)
- png_data_freer(write_ptr, write_info_ptr,
- PNG_DESTROY_WILL_FREE_DATA,
- PNG_FREE_PLTE|PNG_FREE_tRNS|PNG_FREE_hIST)
-
-thereby briefly reassigning responsibility for freeing to the user but
-immediately afterwards reassigning it once more to the write_destroy
-function. Having done this, it would then be safe to destroy the read
-structure and continue to use the PLTE, tRNS, and hIST data in the write
-structure.
-
-This function only affects data that has already been allocated.
-You can call this function before calling after the png_set_*() functions
-to control whether the user or png_destroy_*() is supposed to free the data.
-When the user assumes responsibility for libpng-allocated data, the
-application must use
-png_free() to free it, and when the user transfers responsibility to libpng
-for data that the user has allocated, the user must have used png_malloc()
-or png_zalloc() to allocate it.
-
-If you allocated text_ptr.text, text_ptr.lang, and text_ptr.translated_keyword
-separately, do not transfer responsibility for freeing text_ptr to libpng,
-because when libpng fills a png_text structure it combines these members with
-the key member, and png_free_data() will free only text_ptr.key. Similarly,
-if you transfer responsibility for free'ing text_ptr from libpng to your
-application, your application must not separately free those members.
-For a more compact example of writing a PNG image, see the file example.c.
-
-.SH V. Modifying/Customizing libpng:
-
-There are two issues here. The first is changing how libpng does
-standard things like memory allocation, input/output, and error handling.
-The second deals with more complicated things like adding new chunks,
-adding new transformations, and generally changing how libpng works.
-Both of those are compile-time issues; that is, they are generally
-determined at the time the code is written, and there is rarely a need
-to provide the user with a means of changing them.
-
-Memory allocation, input/output, and error handling
-
-All of the memory allocation, input/output, and error handling in libpng
-goes through callbacks that are user-settable. The default routines are
-in pngmem.c, pngrio.c, pngwio.c, and pngerror.c, respectively. To change
-these functions, call the appropriate png_set_*_fn() function.
-
-Memory allocation is done through the functions png_malloc(), png_calloc(),
-and png_free(). These currently just call the standard C functions.
-png_calloc() calls png_malloc() and then png_memset() to clear the newly
-allocated memory to zero. If your pointers can't access more then 64K
-at a time, you will want to set MAXSEG_64K in zlib.h. Since it is
-unlikely that the method of handling memory allocation on a platform
-will change between applications, these functions must be modified in
-the library at compile time. If you prefer to use a different method
-of allocating and freeing data, you can use png_create_read_struct_2() or
-png_create_write_struct_2() to register your own functions as described
-above. These functions also provide a void pointer that can be retrieved
-via
-
- mem_ptr=png_get_mem_ptr(png_ptr);
-
-Your replacement memory functions must have prototypes as follows:
-
- png_voidp malloc_fn(png_structp png_ptr,
- png_alloc_size_t size);
- void free_fn(png_structp png_ptr, png_voidp ptr);
-
-Your malloc_fn() must return NULL in case of failure. The png_malloc()
-function will normally call png_error() if it receives a NULL from the
-system memory allocator or from your replacement malloc_fn().
-
-Your free_fn() will never be called with a NULL ptr, since libpng's
-png_free() checks for NULL before calling free_fn().
-
-Input/Output in libpng is done through png_read() and png_write(),
-which currently just call fread() and fwrite(). The FILE * is stored in
-png_struct and is initialized via png_init_io(). If you wish to change
-the method of I/O, the library supplies callbacks that you can set
-through the function png_set_read_fn() and png_set_write_fn() at run
-time, instead of calling the png_init_io() function. These functions
-also provide a void pointer that can be retrieved via the function
-png_get_io_ptr(). For example:
-
- png_set_read_fn(png_structp read_ptr,
- voidp read_io_ptr, png_rw_ptr read_data_fn)
-
- png_set_write_fn(png_structp write_ptr,
- voidp write_io_ptr, png_rw_ptr write_data_fn,
- png_flush_ptr output_flush_fn);
-
- voidp read_io_ptr = png_get_io_ptr(read_ptr);
- voidp write_io_ptr = png_get_io_ptr(write_ptr);
-
-The replacement I/O functions must have prototypes as follows:
-
- void user_read_data(png_structp png_ptr,
- png_bytep data, png_size_t length);
- void user_write_data(png_structp png_ptr,
- png_bytep data, png_size_t length);
- void user_flush_data(png_structp png_ptr);
-
-The user_read_data() function is responsible for detecting and
-handling end-of-data errors.
-
-Supplying NULL for the read, write, or flush functions sets them back
-to using the default C stream functions, which expect the io_ptr to
-point to a standard *FILE structure. It is probably a mistake
-to use NULL for one of write_data_fn and output_flush_fn but not both
-of them, unless you have built libpng with PNG_NO_WRITE_FLUSH defined.
-It is an error to read from a write stream, and vice versa.
-
-Error handling in libpng is done through png_error() and png_warning().
-Errors handled through png_error() are fatal, meaning that png_error()
-should never return to its caller. Currently, this is handled via
-setjmp() and longjmp() (unless you have compiled libpng with
-PNG_NO_SETJMP, in which case it is handled via PNG_ABORT()),
-but you could change this to do things like exit() if you should wish,
-as long as your function does not return.
-
-On non-fatal errors, png_warning() is called
-to print a warning message, and then control returns to the calling code.
-By default png_error() and png_warning() print a message on stderr via
-fprintf() unless the library is compiled with PNG_NO_CONSOLE_IO defined
-(because you don't want the messages) or PNG_NO_STDIO defined (because
-fprintf() isn't available). If you wish to change the behavior of the error
-functions, you will need to set up your own message callbacks. These
-functions are normally supplied at the time that the png_struct is created.
-It is also possible to redirect errors and warnings to your own replacement
-functions after png_create_*_struct() has been called by calling:
-
- png_set_error_fn(png_structp png_ptr,
- png_voidp error_ptr, png_error_ptr error_fn,
- png_error_ptr warning_fn);
-
- png_voidp error_ptr = png_get_error_ptr(png_ptr);
-
-If NULL is supplied for either error_fn or warning_fn, then the libpng
-default function will be used, calling fprintf() and/or longjmp() if a
-problem is encountered. The replacement error functions should have
-parameters as follows:
-
- void user_error_fn(png_structp png_ptr,
- png_const_charp error_msg);
- void user_warning_fn(png_structp png_ptr,
- png_const_charp warning_msg);
-
-The motivation behind using setjmp() and longjmp() is the C++ throw and
-catch exception handling methods. This makes the code much easier to write,
-as there is no need to check every return code of every function call.
-However, there are some uncertainties about the status of local variables
-after a longjmp, so the user may want to be careful about doing anything
-after setjmp returns non-zero besides returning itself. Consult your
-compiler documentation for more details. For an alternative approach, you
-may wish to use the "cexcept" facility (see http://cexcept.sourceforge.net),
-which is illustrated in pngvalid.c and in contrib/visupng.
-
-.SS Custom chunks
-
-If you need to read or write custom chunks, you may need to get deeper
-into the libpng code. The library now has mechanisms for storing
-and writing chunks of unknown type; you can even declare callbacks
-for custom chunks. However, this may not be good enough if the
-library code itself needs to know about interactions between your
-chunk and existing `intrinsic' chunks.
-
-If you need to write a new intrinsic chunk, first read the PNG
-specification. Acquire a first level of understanding of how it works.
-Pay particular attention to the sections that describe chunk names,
-and look at how other chunks were designed, so you can do things
-similarly. Second, check out the sections of libpng that read and
-write chunks. Try to find a chunk that is similar to yours and use
-it as a template. More details can be found in the comments inside
-the code. It is best to handle private or unknown chunks in a generic method,
-via callback functions, instead of by modifying libpng functions. This
-is illustrated in pngtest.c, which uses a callback function to handle a
-private "vpAg" chunk and the new "sTER" chunk, which are both unknown to
-libpng.
-
-If you wish to write your own transformation for the data, look through
-the part of the code that does the transformations, and check out some of
-the simpler ones to get an idea of how they work. Try to find a similar
-transformation to the one you want to add and copy off of it. More details
-can be found in the comments inside the code itself.
-
-.SS Configuring for 16 bit platforms
-
-You will want to look into zconf.h to tell zlib (and thus libpng) that
-it cannot allocate more then 64K at a time. Even if you can, the memory
-won't be accessible. So limit zlib and libpng to 64K by defining MAXSEG_64K.
-
-.SS Configuring for DOS
-
-For DOS users who only have access to the lower 640K, you will
-have to limit zlib's memory usage via a png_set_compression_mem_level()
-call. See zlib.h or zconf.h in the zlib library for more information.
-
-.SS Configuring for Medium Model
-
-Libpng's support for medium model has been tested on most of the popular
-compilers. Make sure MAXSEG_64K gets defined, USE_FAR_KEYWORD gets
-defined, and FAR gets defined to far in pngconf.h, and you should be
-all set. Everything in the library (except for zlib's structure) is
-expecting far data. You must use the typedefs with the p or pp on
-the end for pointers (or at least look at them and be careful). Make
-note that the rows of data are defined as png_bytepp, which is an
-unsigned char far * far *.
-
-.SS Configuring for gui/windowing platforms:
-
-You will need to write new error and warning functions that use the GUI
-interface, as described previously, and set them to be the error and
-warning functions at the time that png_create_*_struct() is called,
-in order to have them available during the structure initialization.
-They can be changed later via png_set_error_fn(). On some compilers,
-you may also have to change the memory allocators (png_malloc, etc.).
-
-.SS Configuring for compiler xxx:
-
-All includes for libpng are in pngconf.h. If you need to add, change
-or delete an include, this is the place to do it.
-The includes that are not needed outside libpng are placed in pngpriv.h,
-which is only used by the routines inside libpng itself.
-The files in libpng proper only include pngpriv.h and png.h, which
-in turn includes pngconf.h.
-
-.SS Configuring zlib:
-
-There are special functions to configure the compression. Perhaps the
-most useful one changes the compression level, which currently uses
-input compression values in the range 0 - 9. The library normally
-uses the default compression level (Z_DEFAULT_COMPRESSION = 6). Tests
-have shown that for a large majority of images, compression values in
-the range 3-6 compress nearly as well as higher levels, and do so much
-faster. For online applications it may be desirable to have maximum speed
-(Z_BEST_SPEED = 1). With versions of zlib after v0.99, you can also
-specify no compression (Z_NO_COMPRESSION = 0), but this would create
-files larger than just storing the raw bitmap. You can specify the
-compression level by calling:
-
- png_set_compression_level(png_ptr, level);
-
-Another useful one is to reduce the memory level used by the library.
-The memory level defaults to 8, but it can be lowered if you are
-short on memory (running DOS, for example, where you only have 640K).
-Note that the memory level does have an effect on compression; among
-other things, lower levels will result in sections of incompressible
-data being emitted in smaller stored blocks, with a correspondingly
-larger relative overhead of up to 15% in the worst case.
-
- png_set_compression_mem_level(png_ptr, level);
-
-The other functions are for configuring zlib. They are not recommended
-for normal use and may result in writing an invalid PNG file. See
-zlib.h for more information on what these mean.
-
- png_set_compression_strategy(png_ptr,
- strategy);
- png_set_compression_window_bits(png_ptr,
- window_bits);
- png_set_compression_method(png_ptr, method);
- png_set_compression_buffer_size(png_ptr, size);
-
-.SS Controlling row filtering
-
-If you want to control whether libpng uses filtering or not, which
-filters are used, and how it goes about picking row filters, you
-can call one of these functions. The selection and configuration
-of row filters can have a significant impact on the size and
-encoding speed and a somewhat lesser impact on the decoding speed
-of an image. Filtering is enabled by default for RGB and grayscale
-images (with and without alpha), but not for paletted images nor
-for any images with bit depths less than 8 bits/pixel.
-
-The 'method' parameter sets the main filtering method, which is
-currently only '0' in the PNG 1.2 specification. The 'filters'
-parameter sets which filter(s), if any, should be used for each
-scanline. Possible values are PNG_ALL_FILTERS and PNG_NO_FILTERS
-to turn filtering on and off, respectively.
-
-Individual filter types are PNG_FILTER_NONE, PNG_FILTER_SUB,
-PNG_FILTER_UP, PNG_FILTER_AVG, PNG_FILTER_PAETH, which can be bitwise
-ORed together with '|' to specify one or more filters to use.
-These filters are described in more detail in the PNG specification.
-If you intend to change the filter type during the course of writing
-the image, you should start with flags set for all of the filters
-you intend to use so that libpng can initialize its internal
-structures appropriately for all of the filter types. (Note that this
-means the first row must always be adaptively filtered, because libpng
-currently does not allocate the filter buffers until png_write_row()
-is called for the first time.)
-
- filters = PNG_FILTER_NONE | PNG_FILTER_SUB
- PNG_FILTER_UP | PNG_FILTER_AVG |
- PNG_FILTER_PAETH | PNG_ALL_FILTERS;
-
- png_set_filter(png_ptr, PNG_FILTER_TYPE_BASE,
- filters);
- The second parameter can also be
- PNG_INTRAPIXEL_DIFFERENCING if you are
- writing a PNG to be embedded in a MNG
- datastream. This parameter must be the
- same as the value of filter_method used
- in png_set_IHDR().
-
-It is also possible to influence how libpng chooses from among the
-available filters. This is done in one or both of two ways - by
-telling it how important it is to keep the same filter for successive
-rows, and by telling it the relative computational costs of the filters.
-
- double weights[3] = {1.5, 1.3, 1.1},
- costs[PNG_FILTER_VALUE_LAST] =
- {1.0, 1.3, 1.3, 1.5, 1.7};
-
- png_set_filter_heuristics(png_ptr,
- PNG_FILTER_HEURISTIC_WEIGHTED, 3,
- weights, costs);
-
-The weights are multiplying factors that indicate to libpng that the
-row filter should be the same for successive rows unless another row filter
-is that many times better than the previous filter. In the above example,
-if the previous 3 filters were SUB, SUB, NONE, the SUB filter could have a
-"sum of absolute differences" 1.5 x 1.3 times higher than other filters
-and still be chosen, while the NONE filter could have a sum 1.1 times
-higher than other filters and still be chosen. Unspecified weights are
-taken to be 1.0, and the specified weights should probably be declining
-like those above in order to emphasize recent filters over older filters.
-
-The filter costs specify for each filter type a relative decoding cost
-to be considered when selecting row filters. This means that filters
-with higher costs are less likely to be chosen over filters with lower
-costs, unless their "sum of absolute differences" is that much smaller.
-The costs do not necessarily reflect the exact computational speeds of
-the various filters, since this would unduly influence the final image
-size.
-
-Note that the numbers above were invented purely for this example and
-are given only to help explain the function usage. Little testing has
-been done to find optimum values for either the costs or the weights.
-
-.SS Removing unwanted object code
-
-There are a bunch of #define's in pngconf.h that control what parts of
-libpng are compiled. All the defines end in _SUPPORTED. If you are
-never going to use a capability, you can change the #define to #undef
-before recompiling libpng and save yourself code and data space, or
-you can turn off individual capabilities with defines that begin with
-PNG_NO_.
-
-You can also turn all of the transforms and ancillary chunk capabilities
-off en masse with compiler directives that define
-PNG_NO_READ[or WRITE]_TRANSFORMS, or PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS,
-or all four,
-along with directives to turn on any of the capabilities that you do
-want. The PNG_NO_READ[or WRITE]_TRANSFORMS directives disable the extra
-transformations but still leave the library fully capable of reading
-and writing PNG files with all known public chunks. Use of the
-PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS directive produces a library
-that is incapable of reading or writing ancillary chunks. If you are
-not using the progressive reading capability, you can turn that off
-with PNG_NO_PROGRESSIVE_READ (don't confuse this with the INTERLACING
-capability, which you'll still have).
-
-All the reading and writing specific code are in separate files, so the
-linker should only grab the files it needs. However, if you want to
-make sure, or if you are building a stand alone library, all the
-reading files start with "pngr" and all the writing files start with "pngw".
-The files that don't match either (like png.c, pngtrans.c, etc.)
-are used for both reading and writing, and always need to be included.
-The progressive reader is in pngpread.c
-
-If you are creating or distributing a dynamically linked library (a .so
-or DLL file), you should not remove or disable any parts of the library,
-as this will cause applications linked with different versions of the
-library to fail if they call functions not available in your library.
-The size of the library itself should not be an issue, because only
-those sections that are actually used will be loaded into memory.
-
-.SS Requesting debug printout
-
-The macro definition PNG_DEBUG can be used to request debugging
-printout. Set it to an integer value in the range 0 to 3. Higher
-numbers result in increasing amounts of debugging information. The
-information is printed to the "stderr" file, unless another file
-name is specified in the PNG_DEBUG_FILE macro definition.
-
-When PNG_DEBUG > 0, the following functions (macros) become available:
-
- png_debug(level, message)
- png_debug1(level, message, p1)
- png_debug2(level, message, p1, p2)
-
-in which "level" is compared to PNG_DEBUG to decide whether to print
-the message, "message" is the formatted string to be printed,
-and p1 and p2 are parameters that are to be embedded in the string
-according to printf-style formatting directives. For example,
-
- png_debug1(2, "foo=%d\n", foo);
-
-is expanded to
-
- if(PNG_DEBUG > 2)
- fprintf(PNG_DEBUG_FILE, "foo=%d\n", foo);
-
-When PNG_DEBUG is defined but is zero, the macros aren't defined, but you
-can still use PNG_DEBUG to control your own debugging:
-
- #ifdef PNG_DEBUG
- fprintf(stderr, ...
- #endif
-
-When PNG_DEBUG = 1, the macros are defined, but only png_debug statements
-having level = 0 will be printed. There aren't any such statements in
-this version of libpng, but if you insert some they will be printed.
-
-.SH VI. MNG support
-
-The MNG specification (available at http://www.libpng.org/pub/mng) allows
-certain extensions to PNG for PNG images that are embedded in MNG datastreams.
-Libpng can support some of these extensions. To enable them, use the
-png_permit_mng_features() function:
-
- feature_set = png_permit_mng_features(png_ptr, mask)
- mask is a png_uint_32 containing the bitwise OR of the
- features you want to enable. These include
- PNG_FLAG_MNG_EMPTY_PLTE
- PNG_FLAG_MNG_FILTER_64
- PNG_ALL_MNG_FEATURES
- feature_set is a png_uint_32 that is the bitwise AND of
- your mask with the set of MNG features that is
- supported by the version of libpng that you are using.
-
-It is an error to use this function when reading or writing a standalone
-PNG file with the PNG 8-byte signature. The PNG datastream must be wrapped
-in a MNG datastream. As a minimum, it must have the MNG 8-byte signature
-and the MHDR and MEND chunks. Libpng does not provide support for these
-or any other MNG chunks; your application must provide its own support for
-them. You may wish to consider using libmng (available at
-http://www.libmng.com) instead.
-
-.SH VII. Changes to Libpng from version 0.88
-
-It should be noted that versions of libpng later than 0.96 are not
-distributed by the original libpng author, Guy Schalnat, nor by
-Andreas Dilger, who had taken over from Guy during 1996 and 1997, and
-distributed versions 0.89 through 0.96, but rather by another member
-of the original PNG Group, Glenn Randers-Pehrson. Guy and Andreas are
-still alive and well, but they have moved on to other things.
-
-The old libpng functions png_read_init(), png_write_init(),
-png_info_init(), png_read_destroy(), and png_write_destroy() have been
-moved to PNG_INTERNAL in version 0.95 to discourage their use. These
-functions will be removed from libpng version 2.0.0.
-
-The preferred method of creating and initializing the libpng structures is
-via the png_create_read_struct(), png_create_write_struct(), and
-png_create_info_struct() because they isolate the size of the structures
-from the application, allow version error checking, and also allow the
-use of custom error handling routines during the initialization, which
-the old functions do not. The functions png_read_destroy() and
-png_write_destroy() do not actually free the memory that libpng
-allocated for these structs, but just reset the data structures, so they
-can be used instead of png_destroy_read_struct() and
-png_destroy_write_struct() if you feel there is too much system overhead
-allocating and freeing the png_struct for each image read.
-
-Setting the error callbacks via png_set_message_fn() before
-png_read_init() as was suggested in libpng-0.88 is no longer supported
-because this caused applications that do not use custom error functions
-to fail if the png_ptr was not initialized to zero. It is still possible
-to set the error callbacks AFTER png_read_init(), or to change them with
-png_set_error_fn(), which is essentially the same function, but with a new
-name to force compilation errors with applications that try to use the old
-method.
-
-Starting with version 1.0.7, you can find out which version of the library
-you are using at run-time:
-
- png_uint_32 libpng_vn = png_access_version_number();
-
-The number libpng_vn is constructed from the major version, minor
-version with leading zero, and release number with leading zero,
-(e.g., libpng_vn for version 1.0.7 is 10007).
-
-You can also check which version of png.h you used when compiling your
-application:
-
- png_uint_32 application_vn = PNG_LIBPNG_VER;
-
-.SH VIII. Changes to Libpng from version 1.0.x to 1.2.x
-
-Support for user memory management was enabled by default. To
-accomplish this, the functions png_create_read_struct_2(),
-png_create_write_struct_2(), png_set_mem_fn(), png_get_mem_ptr(),
-png_malloc_default(), and png_free_default() were added.
-
-Support for the iTXt chunk has been enabled by default as of
-version 1.2.41.
-
-Support for certain MNG features was enabled.
-
-Support for numbered error messages was added. However, we never got
-around to actually numbering the error messages. The function
-png_set_strip_error_numbers() was added (Note: the prototype for this
-function was inadvertently removed from png.h in PNG_NO_ASSEMBLER_CODE
-builds of libpng-1.2.15. It was restored in libpng-1.2.36).
-
-The png_malloc_warn() function was added at libpng-1.2.3. This issues
-a png_warning and returns NULL instead of aborting when it fails to
-acquire the requested memory allocation.
-
-Support for setting user limits on image width and height was enabled
-by default. The functions png_set_user_limits(), png_get_user_width_max(),
-and png_get_user_height_max() were added at libpng-1.2.6.
-
-The png_set_add_alpha() function was added at libpng-1.2.7.
-
-The function png_set_expand_gray_1_2_4_to_8() was added at libpng-1.2.9.
-Unlike png_set_gray_1_2_4_to_8(), the new function does not expand the
-tRNS chunk to alpha. The png_set_gray_1_2_4_to_8() function is
-deprecated.
-
-A number of macro definitions in support of runtime selection of
-assembler code features (especially Intel MMX code support) were
-added at libpng-1.2.0:
-
- PNG_ASM_FLAG_MMX_SUPPORT_COMPILED
- PNG_ASM_FLAG_MMX_SUPPORT_IN_CPU
- PNG_ASM_FLAG_MMX_READ_COMBINE_ROW
- PNG_ASM_FLAG_MMX_READ_INTERLACE
- PNG_ASM_FLAG_MMX_READ_FILTER_SUB
- PNG_ASM_FLAG_MMX_READ_FILTER_UP
- PNG_ASM_FLAG_MMX_READ_FILTER_AVG
- PNG_ASM_FLAG_MMX_READ_FILTER_PAETH
- PNG_ASM_FLAGS_INITIALIZED
- PNG_MMX_READ_FLAGS
- PNG_MMX_FLAGS
- PNG_MMX_WRITE_FLAGS
- PNG_MMX_FLAGS
-
-We added the following functions in support of runtime
-selection of assembler code features:
-
- png_get_mmx_flagmask()
- png_set_mmx_thresholds()
- png_get_asm_flags()
- png_get_mmx_bitdepth_threshold()
- png_get_mmx_rowbytes_threshold()
- png_set_asm_flags()
-
-We replaced all of these functions with simple stubs in libpng-1.2.20,
-when the Intel assembler code was removed due to a licensing issue.
-
-These macros are deprecated:
-
- PNG_READ_TRANSFORMS_NOT_SUPPORTED
- PNG_PROGRESSIVE_READ_NOT_SUPPORTED
- PNG_NO_SEQUENTIAL_READ_SUPPORTED
- PNG_WRITE_TRANSFORMS_NOT_SUPPORTED
- PNG_READ_ANCILLARY_CHUNKS_NOT_SUPPORTED
- PNG_WRITE_ANCILLARY_CHUNKS_NOT_SUPPORTED
-
-They have been replaced, respectively, by:
-
- PNG_NO_READ_TRANSFORMS
- PNG_NO_PROGRESSIVE_READ
- PNG_NO_SEQUENTIAL_READ
- PNG_NO_WRITE_TRANSFORMS
- PNG_NO_READ_ANCILLARY_CHUNKS
- PNG_NO_WRITE_ANCILLARY_CHUNKS
-
-PNG_MAX_UINT was replaced with PNG_UINT_31_MAX. It has been
-deprecated since libpng-1.0.16 and libpng-1.2.6.
-
-The function
- png_check_sig(sig, num)
-was replaced with
- !png_sig_cmp(sig, 0, num)
-It has been deprecated since libpng-0.90.
-
-The function
- png_set_gray_1_2_4_to_8()
-which also expands tRNS to alpha was replaced with
- png_set_expand_gray_1_2_4_to_8()
-which does not. It has been deprecated since libpng-1.0.18 and 1.2.9.
-
-.SH IX. Changes to Libpng from version 1.0.x/1.2.x to 1.4.x
-
-Private libpng prototypes and macro definitions were moved from
-png.h and pngconf.h into a new pngpriv.h header file.
-
-Functions png_set_benign_errors(), png_benign_error(), and
-png_chunk_benign_error() were added.
-
-Support for setting the maximum amount of memory that the application
-will allocate for reading chunks was added, as a security measure.
-The functions png_set_chunk_cache_max() and png_get_chunk_cache_max()
-were added to the library.
-
-We implemented support for I/O states by adding png_ptr member io_state
-and functions png_get_io_chunk_name() and png_get_io_state() in pngget.c
-
-We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
-input transforms.
-
-Checking for and reporting of errors in the IHDR chunk is more thorough.
-
-Support for global arrays was removed, to improve thread safety.
-
-Some obsolete/deprecated macros and functions have been removed.
-
-Typecasted NULL definitions such as
- #define png_voidp_NULL (png_voidp)NULL
-were eliminated. If you used these in your application, just use
-NULL instead.
-
-The png_struct and info_struct members "trans" and "trans_values" were
-changed to "trans_alpha" and "trans_color", respectively.
-
-The obsolete, unused pnggccrd.c and pngvcrd.c files and related makefiles
-were removed.
-
-The PNG_1_0_X and PNG_1_2_X macros were eliminated.
-
-The PNG_LEGACY_SUPPORTED macro was eliminated.
-
-Many WIN32_WCE #ifdefs were removed.
-
-The functions png_read_init(info_ptr), png_write_init(info_ptr),
-png_info_init(info_ptr), png_read_destroy(), and png_write_destroy()
-have been removed. They have been deprecated since libpng-0.95.
-
-The png_permit_empty_plte() was removed. It has been deprecated
-since libpng-1.0.9. Use png_permit_mng_features() instead.
-
-We removed the obsolete stub functions png_get_mmx_flagmask(),
-png_set_mmx_thresholds(), png_get_asm_flags(),
-png_get_mmx_bitdepth_threshold(), png_get_mmx_rowbytes_threshold(),
-png_set_asm_flags(), and png_mmx_supported()
-
-We removed the obsolete png_check_sig(), png_memcpy_check(), and
-png_memset_check() functions. Instead use !png_sig_cmp(), png_memcpy(),
-and png_memset(), respectively.
-
-The function png_set_gray_1_2_4_to_8() was removed. It has been
-deprecated since libpng-1.0.18 and 1.2.9, when it was replaced with
-png_set_expand_gray_1_2_4_to_8() because the former function also
-expanded palette images.
-
-Macros for png_get_uint_16, png_get_uint_32, and png_get_int_32
-were added and are used by default instead of the corresponding
-functions. Unfortunately,
-from libpng-1.4.0 until 1.4.4, the png_get_uint_16 macro (but not the
-function) incorrectly returned a value of type png_uint_32.
-
-We changed the prototype for png_malloc() from
- png_malloc(png_structp png_ptr, png_uint_32 size)
-to
- png_malloc(png_structp png_ptr, png_alloc_size_t size)
-
-This also applies to the prototype for the user replacement malloc_fn().
-
-The png_calloc() function was added and is used in place of
-of "png_malloc(); png_memset();" except in the case in png_read_png()
-where the array consists of pointers; in this case a "for" loop is used
-after the png_malloc() to set the pointers to NULL, to give robust.
-behavior in case the application runs out of memory part-way through
-the process.
-
-We changed the prototypes of png_get_compression_buffer_size() and
-png_set_compression_buffer_size() to work with png_size_t instead of
-png_uint_32.
-
-Support for numbered error messages was removed by default, since we
-never got around to actually numbering the error messages. The function
-png_set_strip_error_numbers() was removed from the library by default.
-
-The png_zalloc() and png_zfree() functions are no longer exported.
-The png_zalloc() function no longer zeroes out the memory that it
-allocates.
-
-Support for dithering was disabled by default in libpng-1.4.0, because
-it has not been well tested and doesn't actually "dither".
-The code was not
-removed, however, and could be enabled by building libpng with
-PNG_READ_DITHER_SUPPORTED defined. In libpng-1.4.2, this support
-was reenabled, but the function was renamed png_set_quantize() to
-reflect more accurately what it actually does. At the same time,
-the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros were also renamed to
-PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS.
-
-We removed the trailing '.' from the warning and error messages.
-
-.SH X. Detecting libpng
-
-The png_get_io_ptr() function has been present since libpng-0.88, has never
-changed, and is unaffected by conditional compilation macros. It is the
-best choice for use in configure scripts for detecting the presence of any
-libpng version since 0.88. In an autoconf "configure.in" you could use
-
- AC_CHECK_LIB(png, png_get_io_ptr, ...
-
-.SH XI. Source code repository
-
-Since about February 2009, version 1.2.34, libpng has been under "git" source
-control. The git repository was built from old libpng-x.y.z.tar.gz files
-going back to version 0.70. You can access the git repository (read only)
-at
-
- git://libpng.git.sourceforge.net/gitroot/libpng
-
-or you can browse it via "gitweb" at
-
- http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng
-
-Patches can be sent to glennrp at users.sourceforge.net or to
-png-mng-implement at lists.sourceforge.net or you can upload them to
-the libpng bug tracker at
-
- http://libpng.sourceforge.net
-
-.SH XII. Coding style
-
-Our coding style is similar to the "Allman" style, with curly
-braces on separate lines:
-
- if (condition)
- {
- action;
- }
-
- else if (another condition)
- {
- another action;
- }
-
-The braces can be omitted from simple one-line actions:
-
- if (condition)
- return (0);
-
-We use 3-space indentation, except for continued statements which
-are usually indented the same as the first line of the statement
-plus four more spaces.
-
-For macro definitions we use 2-space indentation, always leaving the "#"
-in the first column.
-
- #ifndef PNG_NO_FEATURE
- # ifndef PNG_FEATURE_SUPPORTED
- # define PNG_FEATURE_SUPPORTED
- # endif
- #endif
-
-Comments appear with the leading "/*" at the same indentation as
-the statement that follows the comment:
-
- /* Single-line comment */
- statement;
-
- /* This is a multiple-line
- * comment.
- */
- statement;
-
-Very short comments can be placed after the end of the statement
-to which they pertain:
-
- statement; /* comment */
-
-We don't use C++ style ("//") comments. We have, however,
-used them in the past in some now-abandoned MMX assembler
-code.
-
-Functions and their curly braces are not indented, and
-exported functions are marked with PNGAPI:

-
-To avoid polluting the global namespace, the names of all exported
-functions and variables begin with "png_", and all publicly visible C
-preprocessor macros begin with "PNG". We request that applications that
-use libpng *not* begin any of their own symbols with either of these strings.
-
-We put a space after each comma and after each semicolon
-in "for" statments, and we put spaces before and after each
-C binary operator and after "for" or "while", and before
-"?". We don't put a space between a typecast and the expression
-being cast, nor do we put one between a function name and the
-left parenthesis that follows it:
-
- for (i = 2; i > 0; --i)
- y[i] = a(x) + (int)b;
-
-We prefer #ifdef and #ifndef to #if defined() and if !defined()
-when there is only one macro being tested.
-
-We do not use the TAB character for indentation in the C sources.
-
-Lines do not exceed 80 characters.

-Other rules can be inferred by inspecting the libpng source.

-.SH XIII. Y2K Compliance in libpng
-
-July 10, 2012
-
-Since the PNG Development group is an ad-hoc body, we can't make
-an official declaration.
-
-This is your unofficial assurance that libpng from version 0.71 and
-upward through 1.4.12 are Y2K compliant. It is my belief that earlier
-versions were also Y2K compliant.
-
-Libpng only has three year fields. One is a 2-byte unsigned integer that
-will hold years up to 65535. The other two hold the date in text
-format, and will hold years up to 9999.
-
-The integer is
- "png_uint_16 year" in png_time_struct.
-
-The strings are
- "png_charp time_buffer" in png_struct and
- "near_time_buffer", which is a local character string in png.c.
-
-There are seven time-related functions:
-
- png_convert_to_rfc_1123() in png.c
- (formerly png_convert_to_rfc_1152() in error)
- png_convert_from_struct_tm() in pngwrite.c, called
- in pngwrite.c
- png_convert_from_time_t() in pngwrite.c
- png_get_tIME() in pngget.c
- png_handle_tIME() in pngrutil.c, called in pngread.c
- png_set_tIME() in pngset.c
- png_write_tIME() in pngwutil.c, called in pngwrite.c
-
-All appear to handle dates properly in a Y2K environment. The
-png_convert_from_time_t() function calls gmtime() to convert from system
-clock time, which returns (year - 1900), which we properly convert to
-the full 4-digit year. There is a possibility that applications using
-libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
-function, or that they are incorrectly passing only a 2-digit year
-instead of "year - 1900" into the png_convert_from_struct_tm() function,
-but this is not under our control. The libpng documentation has always
-stated that it works with 4-digit years, and the APIs have been
-documented as such.
-
-The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
-integer to hold the year, and can hold years as large as 65535.
-
-zlib, upon which libpng depends, is also Y2K compliant. It contains
-no date-related code.

-.SH NOTE
-
-Note about libpng version numbers:
-
-Due to various miscommunications, unforeseen code incompatibilities
-and occasional factors outside the authors' control, version numbering
-on the library has not always been consistent and straightforward.
-The following table summarizes matters since version 0.89c, which was
-the first widely used release:
-
- source png.h png.h shared-lib
- version string int version

-used for changes in backward compatibility, as it is intended. The
-PNG_PNGLIB_VER macro, which is not used within libpng but is available
-for applications, is an unsigned integer of the form xyyzz corresponding
-to the source version x.y.z (leading zeros in y and z). Beta versions
-were given the previous public release number plus a letter, until
-version 1.0.6j; from then on they were given the upcoming public
-release number plus "betaNN" or "rcNN".

-# Usage: $progname [OPTION]... [MODE-ARG]...
-#
-# Provide generalized library-building support services.
-#
-# --config show all configuration variables
-# --debug enable verbose shell tracing
-# -n, --dry-run display commands without modifying any files
-# --features display basic configuration information and exit
-# --mode=MODE use operation mode MODE
-# --preserve-dup-deps don't remove duplicate dependency libraries
-# --quiet, --silent don't print informational messages
-# --no-quiet, --no-silent
-# print informational messages (default)
-# --tag=TAG use configuration variables from tag TAG
-# -v, --verbose print more informational messages than default
-# --no-verbose don't print the extra informational messages
-# --version print version information
-# -h, --help, --help-all print short, long, or detailed help message
-#
-# MODE must be one of the following:
-#
-# clean remove files from the build directory
-# compile compile a source file into a libtool object
-# execute automatically set library path, then run a program
-# finish complete the installation of libtool libraries
-# install install libraries or executables
-# link create a library or an executable
-# uninstall remove libraries from an installed directory
-#
-# MODE-ARGS vary depending on the MODE. When passed as first option,
-# `--mode=MODE' may be abbreviated as `MODE' or a unique abbreviation of that.
-# Try `$progname --help --mode=MODE' for a more detailed description of MODE.

-.TH PNG 5 "July 10, 2012"
-.SH NAME
-png \- Portable Network Graphics (PNG) format
-.SH DESCRIPTION
-PNG (Portable Network Graphics) is an extensible file format for the
-lossless, portable, well-compressed storage of raster images. PNG provides
-a patent-free replacement for GIF and can also replace many
-common uses of TIFF. Indexed-color, grayscale, and truecolor images are
-supported, plus an optional alpha channel. Sample depths range from
-1 to 16 bits.
-.br
-
-PNG is designed to work well in online viewing applications, such as the
-World Wide Web, so it is fully streamable with a progressive display
-option. PNG is robust, providing both full file integrity checking and
-fast, simple detection of common transmission errors. Also, PNG can store
-gamma and chromaticity data for improved color matching on heterogeneous
-platforms.

- * Due to various miscommunications, unforeseen code incompatibilities

- * Henceforth the source version will match the shared-library major

- * PNG_LIBPNG_VER macro, which is not used within libpng but is available
- * for applications, is an unsigned integer of the form xyyzz corresponding
- * to the source version x.y.z (leading zeros in y and z). Beta versions
- * were given the previous public release number plus a letter, until
- * version 1.0.6j; from then on they were given the upcoming public
- * release number plus "betaNN" or "rcNN".
- *
- * Binary incompatibility exists only when applications make direct access
- * to the info_ptr or png_ptr members through png.h, and the compiled
- * application is loaded with a different version of the library.
- *
- * DLLNUM will change each time there are forward or backward changes
- * in binary compatibility (e.g., when a new feature is added).
- *
- * See libpng.txt or libpng.3 for more information. The PNG specification
- * is available as a W3C Recommendation and as an ISO Specification,
- * <http://www.w3.org/TR/2003/REC-PNG-20031110/

- * Y2K compliance in libpng:
- * =========================
- *
- * July 10, 2012
- *
- * Since the PNG Development group is an ad-hoc body, we can't make
- * an official declaration.
- *
- * This is your unofficial assurance that libpng from version 0.71 and
- * upward through 1.4.12 are Y2K compliant. It is my belief that earlier
- * versions were also Y2K compliant.
- *
- * Libpng only has three year fields. One is a 2-byte unsigned integer
- * that will hold years up to 65535. The other two hold the date in text
- * format, and will hold years up to 9999.
- *
- * The integer is
- * "png_uint_16 year" in png_time_struct.
- *
- * The strings are
- * "png_charp time_buffer" in png_struct and
- * "near_time_buffer", which is a local character string in png.c.
- *
- * There are seven time-related functions:
- * png.c: png_convert_to_rfc_1123() in png.c
- * (formerly png_convert_to_rfc_1152() in error)
- * png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
- * png_convert_from_time_t() in pngwrite.c
- * png_get_tIME() in pngget.c
- * png_handle_tIME() in pngrutil.c, called in pngread.c
- * png_set_tIME() in pngset.c
- * png_write_tIME() in pngwutil.c, called in pngwrite.c
- *
- * All handle dates properly in a Y2K environment. The
- * png_convert_from_time_t() function calls gmtime() to convert from system
- * clock time, which returns (year - 1900), which we properly convert to
- * the full 4-digit year. There is a possibility that applications using

- * to png_set_expand(). However, it is entirely reasonable that someone
- * might wish to expand an indexed image to RGB but *not* expand a single,
- * fully transparent palette entry to a full alpha channel--perhaps instead
- * convert tRNS to the grayscale/RGB format (16-bit RGB value), or replace
- * the transparent color with a particular RGB value, or drop tRNS entirely.
- * IOW, a future version of the library may make the transformations flag
- * a bit more fine-grained, with separate bits for each of these three
- * functions.
- *
- * More to the point, these functions make it obvious what libpng will be
- * doing, whereas "expand" can (and does) mean any number of things.
- *
- * GRP 20060307: In libpng-1.2.9, png_set_gray_1_2_4_to_8() was modified
- * to expand only the sample depth but not to expand the tRNS to alpha
- * and its name was changed to png_set_expand_gray_1_2_4_to_8().

-/* From Andreas Dilger e-mail to png-implement, 26 March 1998:
- *
- * In most cases, the "simple transparency" should be done prior to doing
- * gray-to-RGB, or you will have to test 3x as many bytes to check if a
- * pixel is transparent. You would also need to make sure that the
- * transparency information is upgraded to RGB.
- *
- * To summarize, the current flow is:
- * - Gray + simple transparency -> compare 1 or 2 gray bytes and composite
- * with background "in place" if transparent,
- * convert to RGB if necessary
- * - Gray + alpha -> composite with gray background and remove alpha bytes,
- * convert to RGB if necessary
- *
- * To support RGB backgrounds for gray images we need:
- * - Gray + simple transparency -> convert to RGB + simple transparency,
- * compare 3 or 6 bytes and composite with
- * background "in place" if transparent
- * (3x compare/pixel compared to doing
- * composite with gray bkgrnd)
- * - Gray + alpha -> convert to RGB + alpha, composite with background and
- * remove alpha bytes (3x float
- * operations/pixel compared with composite
- * on gray background)
- *
- * Greg's change will do this. The reason it wasn't done before is for
- * performance, as this increases the per-pixel operations. If we would check
- * in advance if the background was gray or RGB, and position the gray-to-RGB
- * transform appropriately, then it would save a lot of work/time.

-/* pngtest.c - a simple test program to test libpng
- *
- * Last changed in libpng 1.4.8 [July 7, 2011]
- * Copyright (c) 1998-2011 Glenn Randers-Pehrson
- * (Version 0.96 Copyright (c) 1996, 1997 Andreas Dilger)
- * (Version 0.88 Copyright (c) 1995, 1996 Guy Eric Schalnat, Group 42, Inc.)
- *
- * This code is released under the libpng license.
- * For conditions of distribution and use, see the disclaimer
- * and license in png.h
- *
- * This program reads in a PNG image, writes it out again, and then
- * compares the two files. If the files are identical, this shows that
- * the basic chunk handling, filtering, and (de)compression code is working
- * properly. It does not currently test all of the transforms, although
- * it probably should.
- *
- * The program will report "FAIL" in certain legitimate cases:
- * 1) when the compression level or filter selection method is changed.
- * 2) when the maximum IDAT size (PNG_ZBUF_SIZE in pngconf.h) is not 8192.
- * 3) unknown unsafe-to-copy ancillary chunks or unknown critical chunks
- * exist in the input file.
- * 4) others not listed here...
- * In these cases, it is best to check with another tool such as "pngcheck"
- * to see what the differences between the two files are.
- *
- * If a filename is given on the command-line, then this file is used
- * for the input, rather than the default "pngtest.png". This allows
- * testing a wide variety of files easily. You can also test a number
- * of files at once by typing "pngtest -m file1.png file2.png ..."

-Microsoft Developer Studio Project File, Format Version 6.00 for libpng.
-
-Copyright (C) 2000-2004 Simon-Pierre Cadieux.
-Copyright (C) 2004 Cosmin Truta.
-
-This code is released under the libpng license.
-For conditions of distribution and use, see copyright notice in png.h
-
-NOTE: This project will be removed from libpng-1.5.0. It has
-been replaced with the "vstudio" project.
-
-Assumptions:
-* The libpng source files are in ..\..
-* The zlib source files are in ..\..\..\zlib
-* The zlib project files are in ..\..\..\zlib\projects\visualc6
-
-
-To use:
-
-1) On the main menu, select "File | Open Workspace".
- Open "libpng.dsw".
-
-2) Select "Build | Set Active Configuration".
- Choose the configuration you wish to build.
- (Choose libpng or pngtest; zlib will be built automatically.)
-
-3) Select "Build | Clean".
-
-4) Select "Build | Build ... (F7)". Ignore warning messages about
- not being able to find certain include files (e.g. alloc.h).
-
-5) If you built the sample program (pngtest),
- select "Build | Execute ... (Ctrl+F5)".
-
-
-This project builds the libpng binaries as follows:
-
-* Win32_DLL_Release\libpng14.dll DLL build
-* Win32_DLL_Debug\libpng14d.dll DLL build (debug version)
-* Win32_DLL_VB\libpng14vb.dll DLL build for Visual Basic, using stdcall
-* Win32_LIB_Release\libpng.lib static build
-* Win32_LIB_Debug\libpngd.lib static build (debug version)
-
-
-Notes:
-
-If you change anything in the source files, or select different compiler
-settings, please change the DLL name to something different than any of
-the above names. Also, make sure that in your "pngusr.h" you define
-PNG_USER_PRIVATEBUILD and PNG_USER_DLLFNAME_POSTFIX according to the
-instructions provided in "pngconf.h".
-
-All DLLs built by this project use the Microsoft dynamic C runtime library
-MSVCRT.DLL (MSVCRTD.DLL for debug versions). If you distribute any of the
-above mentioned libraries you should also include this DLL in your package.
-For a list of files that are redistributable in Visual C++ 6.0, see
-Common\Redist\Redist.txt on Disc 1 of the Visual C++ 6.0 product CDs.

-Assumptions:
-* The libpng source files are in ..\..
-* The zlib source files are in ..\..\..\zlib
-* The zlib project file is in . /* Warning: This is until the zlib project
- files get intergrated into the next zlib release. The final zlib project
- directory will then be ..\..\..\zlib\projects\visualc71. */
-
-To use:
-
-1) On the main menu, select "File | Open Solution".
- Open "libpng.sln".
-
-2) Display the Solution Explorer view (Ctrl+Alt+L)
-
-3) Set one of the project as the StartUp project. If you just want to build the
- binaries set "libpng" as the startup project (Select "libpng" tree view
- item + Project | Set as StartUp project). If you want to build and test the
- binaries set it to "pngtest" (Select "pngtest" tree view item +
- Project | Set as StartUp project)
-
-4) Select "Build | Configuration Manager...".
- Choose the configuration you wish to build.
-
-5) Select "Build | Clean Solution".
-
-6) Select "Build | Build Solution (Ctrl-Shift-B)"

-This project builds the libpng binaries as follows:
-
-* Win32_DLL_Release\libpng14.dll DLL build
-* Win32_DLL_Debug\libpng14d.dll DLL build (debug version)
-* Win32_DLL_VB\libpng14vb.dll DLL build for Visual Basic, using stdcall
-* Win32_LIB_Release\libpng.lib static build
-* Win32_LIB_Debug\libpngd.lib static build (debug version)
-
-Notes:
-
-If you change anything in the source files, or select different compiler
-settings, please change the DLL name to something different than any of
-the above names. Also, make sure that in your "pngusr.h" you define
-PNG_USER_PRIVATEBUILD and PNG_USER_DLLFNAME_POSTFIX according to the
-instructions provided in "pngconf.h".
-
-All DLLs built by this project use the Microsoft dynamic C runtime library
-MSVCR71.DLL (MSVCR71D.DLL for debug versions). If you distribute any of the
-above mentioned libraries you may have to include this DLL in your package.
-For a list of files that are redistributable in Visual Studio see
-$(VCINSTALLDIR)\redist.txt.

-VisualStudio instructions
-
-libpng version 1.4.12 - July 10, 2012
-
-Copyright (c) 1998-2010 Glenn Randers-Pehrson
-
-This code is released under the libpng license.
-For conditions of distribution and use, see the disclaimer
-and license in png.h
-
-This directory contains support for building libpng under MicroSoft
-VisualStudio 2010. It may also work under later versions of VisualStudio.
-You should be familiar with VisualStudio before using this directory.
-
-This is a slightly modified copy of the 'vstudio' solution from libpng
-1.5; it is intended to provide compatibility for libpng 1.4 with later
-releases of zlib (from 1.2.4) and to provide a migration aid for 1.5.
-
-A 'VB' DLL is no longer produced - use the standard 'Release' DLL.
-
-Initial preparations
-====================
-You should install the 'official' build of zlib on your system - follow the
-instructions provided on http://www.zlib.net. When a new release is being
-made of zlib the instructions disappear for a while until the new official
-build is available. You will have to wait.
-
-You must enter some information in zlib.props before attempting to build
-with this 'solution'. Please read and edit zlib.props first. You will
-probably not be familiar with the contents of zlib.props - do not worry,
-it is mostly harmless.
-
-Make sure that your official build layout matches the requirements listed
-in zlib.props. Prior to zlib-1.2.4 the official build (1.2.3) placed
-include and library files in different directories - if you find this
-has happened just put them all in the same directory.
-
-This is all you need to do to build the 'release' and 'release library'
-configurations.
-
-Debugging
-=========
-The release configurations default to /Ox optimization. Full debugging
-information is produced (in the .pdb), but if you encounter a problem the
-optimization may make it difficult to debug. Simply rebuild with a lower
-optimization level (e.g. /Od.)
-
-Stop reading here
-=================
-You have enough information to build a working application.
-
-Debug versions have limited support
-===================================
-This solution includes limited support for debug versions of libpng. You
-do not need these unless your own solution itself uses debug builds (it is
-far more effective to debug on the release builds, there is no point building
-a special debug build.)
-
-If, despite the previous paragraph, you still feel you need a debug build you
-will have to download the zlib source as well (http://www.zlib.net) and include
-the directory where you unpack it in zlib.props. This solution will then be
-able to build a minimal zlib sufficient for libpng. This build is only
-suitable for making a debug libpng.
-
-The debug build of libpng is minimally supported. Support for debug builds of
-zlib is also minimal. You really don't want to do this.
-
-This solution only supports the Multi-Threaded DLL C Runtime
-============================================================
-If you examine the solution you will find that it very deliberately lists
-exactly which MicroSoft DLLs it is linking against. It explicitly links
-against msvcrt.lib. The debug version links against msvcrtd.lib (this is
-why it is a debug version - it's nothing to do with having any special
-debug support, it doesn't).
-
-These versions of the MicroSoft C runtime correspond to the compiler flags
-/MD (release) and /MDd (debug) - the "Multi-Threaded DLL" implementation of the
-C runtime library.
-
-If you need to change this then you will have to make sure that both the
-compiler flags and the ".lib" in the linker dependences match up. Fortunately
-neither zlib nor libpng require libraries other than a C runtime and
-kernel32.
-
-You cannot pass (FILE*) objects from a different runtime (including msvcrtd
-to msvcrt) to libpng. If you do then your program will crash within libpng
-when it first makes a file read or write call.
-
-It is likely if you have read this far that you have found you can't avoid
-having multiple C runtimes in your program. This is OK, it does work, but
-you will have to implement the libpng file read/write callbacks rather than
-using the internal libpng default. This is easy.

-.TH OPTIPNG 1 "2012-Oct-21" "OptiPNG version 0.7.4"
-
-.SH NAME
-.B OptiPNG
-\- Optimize Portable Network Graphics files
-
-.SH SYNOPSIS
-.B optipng
-[\fB\-?\fP | \fB\-h\fP | \fB\-help\fP]
-.br
-.B optipng
-[\fIoptions...\fP] \fIfiles...\fP
-
-.SH DESCRIPTION
-The
-.B OptiPNG
-program shall attempt to \fIoptimize\fP PNG files, i.e. reduce their size to
-a minimum, without losing semantic information. In addition, this program shall
-perform a suite of auxiliary functions like integrity checks, metadata recovery
-and pixmap-to-PNG conversion.
-.P
-The optimization attempts are not guaranteed to succeed. Valid PNG files that
-cannot be optimized by this program are normally left intact; their size will
-not grow. The user may request to override this default behavior.
-
-.SH FILES
-The input files are raster image files encoded either in PNG format (the native
-format), or in an external format. The currently supported external formats are
-GIF, BMP, PNM and TIFF.
-.P
-.B OptiPNG
-processes each image file given in the command line as follows:
-.P
-\- If the image is in PNG format:
-.IP
-Attempts to optimize the given file in-place. If optimization is successful, or
-if the option \fB\-force\fP is enabled, replaces the original file with its
-optimized version. The original file is backed up if the option \fB\-keep\fP
-is enabled.
-.P
-\- If the image is in an external format:
-.IP
-Creates an optimized PNG version of the given file. The output file name is
-composed from the original file name and the \fC.png\fP extension.
-.P
-Existing files are \fInot\fP overwritten, unless the option \fB\-clobber\fP is
-enabled.
-
-.SH OPTIONS
-.SS "General options"
-.TP
-\fB\-?\fP, \fB\-h\fP, \fB\-help\fP
-Show a complete summary of options.
-.TP
-\fB\-backup\fP, \fB\-keep\fP
-Keep a backup of the modified files.
-.TP
-\fB\-clobber\fP
-Overwrite the existing output and backup files.
-.br
-Under this option, if the option \fB\-backup\fP is not enabled, the old backups
-of the overwritten files are deleted.
-.TP
-\fB\-dir\fP \fIdirectory\fP
-Write the output files to \fIdirectory\fP.
-.TP
-\fB\-fix\fP
-Enable error recovery. This option has no effect on valid input files.
-.br
-The program will spend a reasonable amount of effort to recover as much data as
-possible, without increasing the output file size, but the success cannot be
-generally guaranteed. The program may even increase the file size, e.g., by
-reconstructing missing critical data. Under this option, integrity shall take
-precedence over file size.
-.br
-When this option is not used, the invalid input files are left unprocessed.
-.TP
-\fB\-force\fP
-Enforce writing of a new output file.
-.br
-This option overrides the program's decision not to write such file, e.g. when
-the PNG input is digitally signed (using dSIG), or when the PNG output becomes
-larger than the PNG input.
-.TP
-\fB\-log\fP \fIfile\fP
-Log messages to \fIfile\fP.
-For safety reasons, \fIfile\fP must have the extension \fC.log\fP.
-.br
-This option is deprecated and will be removed eventually. Use shell
-redirection.
-.TP
-\fB\-out\fP \fIfile\fP
-Write output file to \fIfile\fP.
-The command line must contain exactly one input file.
-.TP
-\fB\-preserve\fP
-Preserve file attributes (time stamps, file access rights, etc.) where
-applicable.
-.TP
-\fB\-quiet\fP, \fB\-silent\fP
-Run in quiet mode.
-.br
-The messages are still written to the log file if the option \fB\-log\fP is
-enabled.
-.TP
-\fB\-simulate\fP
-Run in simulation mode: perform the trials, but do not create output files.
-.TP
-\fB\-v\fP
-Enable the options \fB\-verbose\fP and \fB\-version\fP.
-.TP
-\fB\-verbose\fP
-Run in verbose mode.
-.TP
-\fB\-version\fP
-Show copyright, version and build info.
-.TP
-\fB\-\-\fP
-Stop option switch parsing.
-.SS "PNG encoding and optimization options"
-.TP
-\fB\-o\fP \fIlevel\fP
-Select the optimization level.
-.br
-The optimization level 0 enables a set of optimization operations that require
-minimal effort. There will be no changes to image attributes like bit depth
-or color type, and no recompression of existing IDAT datastreams.
-.br
-The optimization level 1 enables a single IDAT compression trial. The trial
-chosen is what \fBOptiPNG\fP \fIthinks\fP it's probably the most effective.
-.br
-The optimization levels 2 and higher enable multiple IDAT compression trials;
-the higher the level, the more trials.
-.br
-The behavior and the default value of this option may change across different
-program versions. Use the option \fB\-h\fP to see the details pertaining to
-your specific version.
-.TP
-\fB\-f\fP \fIfilters\fP
-Select the PNG delta filters.
-.br
-The \fIfilters\fP argument is specified as a rangeset (e.g. \fB\-f0\-5\fP),
-and the default \fIfilters\fP value depends on the optimization level set by
-the option \fB\-o\fP.
-.br
-The filter values 0, 1, 2, 3 and 4 indicate static filtering, and correspond to
-the standard PNG filter codes (\fINone\fP, \fILeft\fP, \fIUp\fP, \fIAverage\fP
-and \fIPaeth\fP, respectively). The filter value 5 indicates adaptive filtering,
-whose effect is defined by the \fBlibpng\fP(3) library used by \fBOptiPNG\fP.
-.TP
-\fB\-full\fP
-Produce a full report on IDAT.
-This option might slow down the trials.
-.TP
-\fB\-i\fP \fItype\fP
-Select the interlace type (0\-1).
-.br
-If the interlace type 0 is selected, the output image shall be non-interlaced
-(i.e. progressive-scanned). If the interlace type 1 is selected, the output
-image shall be interlaced using the \fIAdam7\fP method.
-.br
-By default, the output shall have the same interlace type as the input.
-.TP
-\fB\-nb\fP
-Do not apply bit depth reduction.
-.TP
-\fB\-nc\fP
-Do not apply color type reduction.
-.TP
-\fB\-np\fP
-Do not apply palette reduction.
-.TP
-\fB\-nx\fP
-Do not apply any lossless image reduction:
-enable the options \fB\-nb\fP, \fB\-nc\fP and \fB\-np\fP.
-.TP
-\fB\-nz\fP
-Do not recode IDAT datastreams.
-.br
-The IDAT optimization operations that do not require recoding (e.g. IDAT
-chunk concatenation) are still performed.
-.br
-This option has effect on PNG input files only.
-.TP
-\fB\-zc\fP \fIlevels\fP
-Select the zlib compression levels used in IDAT compression.
-.br
-The \fIlevels\fP argument is specified as a rangeset (e.g. \fB\-zc6\-9\fP),
-and the default \fIlevels\fP value depends on the optimization level set by
-the option \fB\-o\fP.
-.br
-The effect of this option is defined by the \fBzlib\fP(3) library used by
-\fBOptiPNG\fP.
-.TP
-\fB\-zm\fP \fIlevels\fP
-Select the zlib memory levels used in IDAT compression.
-.br
-The \fIlevels\fP argument is specified as a rangeset (e.g. \fB\-zm8\-9\fP),
-and the default \fIlevels\fP value depends on the optimization level set by
-the option \fB\-o\fP.
-.br
-The effect of this option is defined by the \fBzlib\fP(3) library used by
-\fBOptiPNG\fP.
-.TP
-\fB\-zs\fP \fIstrategies\fP
-Select the zlib compression strategies used in IDAT compression.
-.br
-The \fIstrategies\fP argument is specified as a rangeset (e.g. \fB\-zs0\-3\fP),
-and the default \fIstrategies\fP value depends on the optimization level set by
-the option \fB\-o\fP.
-.br
-The effect of this option is defined by the \fBzlib\fP(3) library used by
-\fBOptiPNG\fP.
-.TP
-\fB\-zw\fP \fIsize\fP
-Select the zlib window size (32k,16k,8k,4k,2k,1k,512,256) used in IDAT
-compression.
-.br
-The \fIsize\fP argument can be specified either in bytes (e.g. 16384) or
-kilobytes (e.g. 16k). The default \fIsize\fP value is set to the lowest
-window size that yields an IDAT output as big as if yielded by the value 32768.
-.br
-The effect of this option is defined by the \fBzlib\fP(3) library used by
-\fBOptiPNG\fP.
-.SS "Editing options"
-.TP
-\fB\-snip\fP
-Cut one image out of multi-image, animation or video files.
-.br
-Depending on the input format, this may be either the first or the most
-relevant (e.g. the largest) image.
-.TP
-\fB\-strip\fP \fIobjects\fP
-Strip metadata objects from a PNG file.
-.br
-PNG metadata is the information stored in any ancillary chunk except tRNS.
-(tRNS represents the alpha channel, which, even if ignored in rendering, is
-still a proper image channel in the RGBA color space.)
-.br
-The only option currently supported is \fB\-strip all\fP.
-.SS "Notes"
-Options may come in any order (except for \fB\-\-\fP), before, after, or
-alternating with file names. Option names are case-insensitive and may be
-abbreviated to their shortest unique prefix.
-.P
-Some options may have arguments that follow the option name, separated by
-whitespace or the equal sign ('\fB=\fP'). If the option argument is a number
-or a rangeset, the separator may be omitted. For example:
-.IP
-\fB\-out\fP \fCnewfile.png\fP \ <=> \ \fB\-out=\fP\fCnewfile.png\fP
-.br
-\fB\-o3\fP \ <=> \ \fB\-o 3\fP \ <=> \ \fB\-o=3\fP
-.br
-\fB\-f0,3\-5\fP \ <=> \ \fB\-f 0,3\-5\fP \ <=> \ \fB\-f=0,3\-5\fP
-.P
-Rangeset arguments are cumulative; e.g.
-.IP
-\fB\-f0 \-f3\-5\fP \ <=> \ \fB\-f0,3\-5\fP
-.br
-\fB\-zs0 \-zs1 \-zs2\-3\fP \ <=> \ \fB\-zs0,1,2,3\fP \ <=> \ \fB\-zs0\-3\fP
-
-.SH "EXTENDED DESCRIPTION"
-The PNG optimization algorithm consists of the following steps:
-.TP 4
-1.
-Reduce the bit depth, the color type and the color palette of the image.
-This step may reduce the size of the uncompressed image, which, indirectly, may
-reduce the size of the compressed image (i.e. the size of the output PNG file).
-.TP 4
-2.
-Run a suite of compression methods and strategies and select the compression
-parameters that yield the smallest output file.
-.TP 4
-3.
-Store all IDAT contents into a single chunk, eliminating the overhead
-incurred by repeated IDAT headers and CRCs.
-.TP 4
-4.
-Set the zlib window size inside IDAT to a mininum that does not affect the
-compression ratio, reducing the memory requirements of PNG decoders.
-.P
-Not all of the above steps need to be executed. The behavior depends on the
-actual input files and user options.
-.P
-Step 1 may be customized via the no-reduce options \fB\-nb\fP, \fB\-nc\fP,
-\fB\-np\fP and \fB\-nx\fP. Step 2 may be customized via the \fB\-o\fP option,
-and may be fine-tuned via the options \fB\-zc\fP, \fB\-zm\fP, \fB\-zs\fP and
-\fB\-zw\fP. Step 3 is always executed. Step 4 is executed only if a new IDAT is
-being created, and may be fine-tuned via the option \fB\-zw\fP.
-.P
-Extremely exhaustive searches are not generally expected to yield significant
-improvements in compression ratio, and are recommended to advanced users only.
-
-.SH EXAMPLES
-\fCoptipng file.png \ \ \ \ \ \fP# default speed
-.br
-\fCoptipng -o5 file.png \ \fP# slow
-.br
-\fCoptipng -o7 file.png \ \fP# very slow
-
-.SH BUGS
-Lossless image reductions are not completely implemented.
-(This does \fInot\fP affect the integrity of the output files.)
-Here are the missing pieces:
-.IP
-\- The color palette reductions are implemented only partially.
-.br
-\- The bit depth reductions below 8, for grayscale images, are not implemented
-yet.
-.P
-Encoding of images whose total IDAT size exceeds 2GB is not supported.
-.P
-TIFF support is limited to uncompressed, PNG-compatible (grayscale, RGB and
-RGBA) images.
-.P
-Metadata is not imported from the external image formats.
-.P
-There is no support for pipes or streams.

- Frequently Asked Questions about zlib
-
-
-If your question is not there, please check the zlib home page
-http://zlib.net/ which may have more recent information.
-The lastest zlib FAQ is at http://zlib.net/zlib_faq.html
-
-
- 1. Is zlib Y2K-compliant?
-
- Yes. zlib doesn't handle dates.
-
- 2. Where can I get a Windows DLL version?
-
- The zlib sources can be compiled without change to produce a DLL. See the
- file win32/DLL_FAQ.txt in the zlib distribution. Pointers to the
- precompiled DLL are found in the zlib web site at http://zlib.net/ .
-
- 3. Where can I get a Visual Basic interface to zlib?
-
- See
- * http://marknelson.us/1997/01/01/zlib-engine/
- * win32/DLL_FAQ.txt in the zlib distribution
-
- 4. compress() returns Z_BUF_ERROR.
-
- Make sure that before the call of compress(), the length of the compressed
- buffer is equal to the available size of the compressed buffer and not
- zero. For Visual Basic, check that this parameter is passed by reference
- ("as any"), not by value ("as long").
-
- 5. deflate() or inflate() returns Z_BUF_ERROR.
-
- Before making the call, make sure that avail_in and avail_out are not zero.
- When setting the parameter flush equal to Z_FINISH, also make sure that
- avail_out is big enough to allow processing all pending input. Note that a
- Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
- made with more input or output space. A Z_BUF_ERROR may in fact be
- unavoidable depending on how the functions are used, since it is not
- possible to tell whether or not there is more output pending when
- strm.avail_out returns with zero. See http://zlib.net/zlib_how.html for a
- heavily annotated example.
-
- 6. Where's the zlib documentation (man pages, etc.)?
-
- It's in zlib.h . Examples of zlib usage are in the files test/example.c
- and test/minigzip.c, with more in examples/ .
-
- 7. Why don't you use GNU autoconf or libtool or ...?
-
- Because we would like to keep zlib as a very small and simple package.
- zlib is rather portable and doesn't need much configuration.
-
- 8. I found a bug in zlib.
-
- Most of the time, such problems are due to an incorrect usage of zlib.
- Please try to reproduce the problem with a small program and send the
- corresponding source to us at zlib@gzip.org . Do not send multi-megabyte
- data files without prior agreement.
-
- 9. Why do I get "undefined reference to gzputc"?
-
- If "make test" produces something like
-
- example.o(.text+0x154): undefined reference to `gzputc'
-
- check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
- /usr/X11R6/lib. Remove any old versions, then do "make install".
-
-10. I need a Delphi interface to zlib.
-
- See the contrib/delphi directory in the zlib distribution.
-
-11. Can zlib handle .zip archives?
-
- Not by itself, no. See the directory contrib/minizip in the zlib
- distribution.
-
-12. Can zlib handle .Z files?
-
- No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
- the code of uncompress on your own.
-
-13. How can I make a Unix shared library?
-
- By default a shared (and a static) library is built for Unix. So:
-
- make distclean
- ./configure
- make
-
-14. How do I install a shared zlib library on Unix?
-
- After the above, then:
-
- make install
-
- However, many flavors of Unix come with a shared zlib already installed.
- Before going to the trouble of compiling a shared version of zlib and
- trying to install it, you may want to check if it's already there! If you
- can #include <zlib.h>, it's there. The -lz option will probably link to
- it. You can check the version at the top of zlib.h or with the
- ZLIB_VERSION symbol defined in zlib.h .
-
-15. I have a question about OttoPDF.
-
- We are not the authors of OttoPDF. The real author is on the OttoPDF web
- site: Joel Hainley, jhainley@myndkryme.com.
-
-16. Can zlib decode Flate data in an Adobe PDF file?
-
- Yes. See http://www.pdflib.com/ . To modify PDF forms, see
- http://sourceforge.net/projects/acroformtool/ .
-
-17. Why am I getting this "register_frame_info not found" error on Solaris?
-
- After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
- generates an error such as:
-
- ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
- symbol __register_frame_info: referenced symbol not found
-
- The symbol __register_frame_info is not part of zlib, it is generated by
- the C compiler (cc or gcc). You must recompile applications using zlib
- which have this problem. This problem is specific to Solaris. See
- http://www.sunfreeware.com for Solaris versions of zlib and applications
- using zlib.
-
-18. Why does gzip give an error on a file I make with compress/deflate?
-
- The compress and deflate functions produce data in the zlib format, which
- is different and incompatible with the gzip format. The gz* functions in
- zlib on the other hand use the gzip format. Both the zlib and gzip formats
- use the same compressed data format internally, but have different headers
- and trailers around the compressed data.
-
-19. Ok, so why are there two different formats?
-
- The gzip format was designed to retain the directory information about a
- single file, such as the name and last modification date. The zlib format
- on the other hand was designed for in-memory and communication channel
- applications, and has a much more compact header and trailer and uses a
- faster integrity check than gzip.
-
-20. Well that's nice, but how do I make a gzip file in memory?
-
- You can request that deflate write the gzip format instead of the zlib
- format using deflateInit2(). You can also request that inflate decode the
- gzip format using inflateInit2(). Read zlib.h for more details.
-
-21. Is zlib thread-safe?
-
- Yes. However any library routines that zlib uses and any application-
- provided memory allocation routines must also be thread-safe. zlib's gz*
- functions use stdio library routines, and most of zlib's functions use the
- library memory allocation routines by default. zlib's *Init* functions
- allow for the application to provide custom memory allocation routines.
-
- Of course, you should only operate on any given zlib or gzip stream from a
- single thread at a time.
-
-22. Can I use zlib in my commercial application?
-
- Yes. Please read the license in zlib.h.
-
-23. Is zlib under the GNU license?
-
- No. Please read the license in zlib.h.
-
-24. The license says that altered source versions must be "plainly marked". So
- what exactly do I need to do to meet that requirement?
-
- You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
- particular, the final version number needs to be changed to "f", and an
- identification string should be appended to ZLIB_VERSION. Version numbers
- x.x.x.f are reserved for modifications to zlib by others than the zlib
- maintainers. For example, if the version of the base zlib you are altering
- is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
- ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3". You can also
- update the version strings in deflate.c and inftrees.c.
-
- For altered source distributions, you should also note the origin and
- nature of the changes in zlib.h, as well as in ChangeLog and README, along
- with the dates of the alterations. The origin should include at least your
- name (or your company's name), and an email address to contact for help or
- issues with the library.
-
- Note that distributing a compiled zlib library along with zlib.h and
- zconf.h is also a source distribution, and so you should change
- ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
- in zlib.h as you would for a full source distribution.
-
-25. Will zlib work on a big-endian or little-endian architecture, and can I
- exchange compressed data between them?
-
- Yes and yes.
-
-26. Will zlib work on a 64-bit machine?
-
- Yes. It has been tested on 64-bit machines, and has no dependence on any
- data types being limited to 32-bits in length. If you have any
- difficulties, please provide a complete problem report to zlib@gzip.org
-
-27. Will zlib decompress data from the PKWare Data Compression Library?
-
- No. The PKWare DCL uses a completely different compressed data format than
- does PKZIP and zlib. However, you can look in zlib's contrib/blast
- directory for a possible solution to your problem.
-
-28. Can I access data randomly in a compressed stream?
-
- No, not without some preparation. If when compressing you periodically use
- Z_FULL_FLUSH, carefully write all the pending data at those points, and
- keep an index of those locations, then you can start decompression at those
- points. You have to be careful to not use Z_FULL_FLUSH too often, since it
- can significantly degrade compression. Alternatively, you can scan a
- deflate stream once to generate an index, and then use that index for
- random access. See examples/zran.c .
-
-29. Does zlib work on MVS, OS/390, CICS, etc.?
-
- It has in the past, but we have not heard of any recent evidence. There
- were working ports of zlib 1.1.4 to MVS, but those links no longer work.
- If you know of recent, successful applications of zlib on these operating
- systems, please let us know. Thanks.
-
-30. Is there some simpler, easier to read version of inflate I can look at to
- understand the deflate format?
-
- First off, you should read RFC 1951. Second, yes. Look in zlib's
- contrib/puff directory.
-
-31. Does zlib infringe on any patents?
-
- As far as we know, no. In fact, that was originally the whole point behind
- zlib. Look here for some more information:
-
- http://www.gzip.org/#faq11
-
-32. Can zlib work with greater than 4 GB of data?
-
- Yes. inflate() and deflate() will process any amount of data correctly.
- Each call of inflate() or deflate() is limited to input and output chunks
- of the maximum value that can be stored in the compiler's "unsigned int"
- type, but there is no limit to the number of chunks. Note however that the
- strm.total_in and strm_total_out counters may be limited to 4 GB. These
- counters are provided as a convenience and are not used internally by
- inflate() or deflate(). The application can easily set up its own counters
- updated after each call of inflate() or deflate() to count beyond 4 GB.
- compress() and uncompress() may be limited to 4 GB, since they operate in a
- single call. gzseek() and gztell() may be limited to 4 GB depending on how
- zlib is compiled. See the zlibCompileFlags() function in zlib.h.
-
- The word "may" appears several times above since there is a 4 GB limit only
- if the compiler's "long" type is 32 bits. If the compiler's "long" type is
- 64 bits, then the limit is 16 exabytes.
-
-33. Does zlib have any security vulnerabilities?
-
- The only one that we are aware of is potentially in gzprintf(). If zlib is
- compiled to use sprintf() or vsprintf(), then there is no protection
- against a buffer overflow of an 8K string space (or other value as set by
- gzbuffer()), other than the caller of gzprintf() assuring that the output
- will not exceed 8K. On the other hand, if zlib is compiled to use
- snprintf() or vsnprintf(), which should normally be the case, then there is
- no vulnerability. The ./configure script will display warnings if an
- insecure variation of sprintf() will be used by gzprintf(). Also the
- zlibCompileFlags() function will return information on what variant of
- sprintf() is used by gzprintf().
-
- If you don't have snprintf() or vsnprintf() and would like one, you can
- find a portable implementation here:
-
- http://www.ijs.si/software/snprintf/
-
- Note that you should be using the most recent version of zlib. Versions
- 1.1.3 and before were subject to a double-free vulnerability, and versions
- 1.2.1 and 1.2.2 were subject to an access exception when decompressing
- invalid compressed data.
-
-34. Is there a Java version of zlib?
-
- Probably what you want is to use zlib in Java. zlib is already included
- as part of the Java SDK in the java.util.zip package. If you really want
- a version of zlib written in the Java language, look on the zlib home
- page for links: http://zlib.net/ .
-
-35. I get this or that compiler or source-code scanner warning when I crank it
- up to maximally-pedantic. Can't you guys write proper code?
-
- Many years ago, we gave up attempting to avoid warnings on every compiler
- in the universe. It just got to be a waste of time, and some compilers
- were downright silly as well as contradicted each other. So now, we simply
- make sure that the code always works.
-
-36. Valgrind (or some similar memory access checker) says that deflate is
- performing a conditional jump that depends on an uninitialized value.
- Isn't that a bug?
-
- No. That is intentional for performance reasons, and the output of deflate
- is not affected. This only started showing up recently since zlib 1.2.x
- uses malloc() by default for allocations, whereas earlier versions used
- calloc(), which zeros out the allocated memory. Even though the code was
- correct, versions 1.2.4 and later was changed to not stimulate these
- checkers.
-
-37. Will zlib read the (insert any ancient or arcane format here) compressed
- data format?
-
- Probably not. Look in the comp.compression FAQ for pointers to various
- formats and associated software.
-
-38. How can I encrypt/decrypt zip files with zlib?
-
- zlib doesn't support encryption. The original PKZIP encryption is very
- weak and can be broken with freely available programs. To get strong
- encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib
- compression. For PKZIP compatible "encryption", look at
- http://www.info-zip.org/
-
-39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
-
- "gzip" is the gzip format, and "deflate" is the zlib format. They should
- probably have called the second one "zlib" instead to avoid confusion with
- the raw deflate compressed data format. While the HTTP 1.1 RFC 2616
- correctly points to the zlib specification in RFC 1950 for the "deflate"
- transfer encoding, there have been reports of servers and browsers that
- incorrectly produce or expect raw deflate data per the deflate
- specification in RFC 1951, most notably Microsoft. So even though the
- "deflate" transfer encoding using the zlib format would be the more
- efficient approach (and in fact exactly what the zlib format was designed
- for), using the "gzip" transfer encoding is probably more reliable due to
- an unfortunate choice of name on the part of the HTTP 1.1 authors.
-
- Bottom line: use the gzip format for HTTP 1.1 encoding.
-
-40. Does zlib support the new "Deflate64" format introduced by PKWare?
-
- No. PKWare has apparently decided to keep that format proprietary, since
- they have not documented it as they have previous compression formats. In
- any case, the compression improvements are so modest compared to other more
- modern approaches, that it's not worth the effort to implement.
-
-41. I'm having a problem with the zip functions in zlib, can you help?
-
- There are no zip functions in zlib. You are probably using minizip by
- Giles Vollant, which is found in the contrib directory of zlib. It is not
- part of zlib. In fact none of the stuff in contrib is part of zlib. The
- files in there are not supported by the zlib authors. You need to contact
- the authors of the respective contribution for help.
-
-42. The match.asm code in contrib is under the GNU General Public License.
- Since it's part of zlib, doesn't that mean that all of zlib falls under the
- GNU GPL?
-
- No. The files in contrib are not part of zlib. They were contributed by
- other authors and are provided as a convenience to the user within the zlib
- distribution. Each item in contrib has its own license.
-
-43. Is zlib subject to export controls? What is its ECCN?
-
- zlib is not subject to export controls, and so is classified as EAR99.
-
-44. Can you please sign these lengthy legal documents and fax them back to us
- so that we can use your software in our product?
-
- No. Go away. Shoo.

-ZLIB DATA COMPRESSION LIBRARY
-
-zlib 1.2.7 is a general purpose data compression library. All the code is
-thread safe. The data format used by the zlib library is described by RFCs
-(Request for Comments) 1950 to 1952 in the files
-http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
-rfc1952 (gzip format).
-
-All functions of the compression library are documented in the file zlib.h
-(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
-of the library is given in the file test/example.c which also tests that
-the library is working correctly. Another example is given in the file
-test/minigzip.c. The compression library itself is composed of all source
-files in the root directory.
-
-To compile all files and run the test program, follow the instructions given at
-the top of Makefile.in. In short "./configure; make test", and if that goes
-well, "make install" should work for most flavors of Unix. For Windows, use
-one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use
-make_vms.com.
-
-Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
-<info@winimage.com> for the Windows DLL version. The zlib home page is
-http://zlib.net/ . Before reporting a problem, please check this site to
-verify that you have the latest version of zlib; otherwise get the latest
-version and check whether the problem still exists or not.
-
-PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
-
-Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
-issue of Dr. Dobb's Journal; a copy of the article is available at
-http://marknelson.us/1997/01/01/zlib-engine/ .
-
-The changes made in version 1.2.7 are documented in the file ChangeLog.
-
-Unsupported third party contributions are provided in directory contrib/ .
-
-zlib is available in Java using the java.util.zip package, documented at
-http://java.sun.com/developer/technicalArticles/Programming/compression/ .
-
-A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
-at CPAN (Comprehensive Perl Archive Network) sites, including
-http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
-
-A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
-available in Python 1.5 and later versions, see
-http://docs.python.org/library/zlib.html .
-
-zlib is built into tcl: http://wiki.tcl.tk/4610 .
-
-An experimental package to read and write files in .zip format, written on top
-of zlib by Gilles Vollant <info@winimage.com>, is available in the
-contrib/minizip directory of zlib.
-
-
-Notes for some targets:
-
-- For Windows DLL versions, please see win32/DLL_FAQ.txt
-
-- For 64-bit Irix, deflate.c must be compiled without any optimization. With
- -O, one libpng test fails. The test works in 32 bit mode (with the -n32
- compiler flag). The compiler bug has been reported to SGI.
-
-- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
- when compiled with cc.
-
-- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
- necessary to get gzprintf working correctly. This is done by configure.
-
-- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
- other compilers. Use "make test" to check your compiler.
-
-- gzdopen is not supported on RISCOS or BEOS.
-
-- For PalmOs, see http://palmzlib.sourceforge.net/
-
-
-Acknowledgments:
-
- The deflate format used by zlib was defined by Phil Katz. The deflate and
- zlib specifications were written by L. Peter Deutsch. Thanks to all the
- people who reported problems and suggested various improvements in zlib; they
- are too numerous to cite here.

-
-I) From an AS400 *SAVF file:
-
-1) Unpacking archive to an AS400 save file
-
-On the AS400:
-
-_ Create the ZLIB AS400 library:
-
- CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
-
-_ Create a work save file, for example:
-
- CRTSAVF FILE(ZLIB/ZLIBSAVF)
-
-On a PC connected to the target AS400:
-
-_ Unpack the save file image to a PC file "ZLIBSAVF"
-_ Upload this file into the save file on the AS400, for example
- using ftp in BINARY mode.
-
-
-2) Populating the ZLIB AS400 source library
-
-On the AS400:
-
-_ Extract the saved objects into the ZLIB AS400 library using:
-
-RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)
-
-
-3) Customize installation:
-
-_ Edit CL member ZLIB/TOOLS(COMPILE) and change parameters if needed,
- according to the comments.
-
-_ Compile this member with:
-
- CRTCLPGM PGM(ZLIB/COMPILE) SRCFILE(ZLIB/TOOLS) SRCMBR(COMPILE)
-
-
-4) Compile and generate the service program:
-
-_ This can now be done by executing:
-
- CALL PGM(ZLIB/COMPILE)
-
-
-
-II) From the original source distribution:
-
-1) On the AS400, create the source library:
-
- CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
-
-2) Create the source files:
-
- CRTSRCPF FILE(ZLIB/SOURCES) RCDLEN(112) TEXT('ZLIB library modules')
- CRTSRCPF FILE(ZLIB/H) RCDLEN(112) TEXT('ZLIB library includes')
- CRTSRCPF FILE(ZLIB/TOOLS) RCDLEN(112) TEXT('ZLIB library control utilities')
-
-3) From the machine hosting the distribution files, upload them (with
- FTP in text mode, for example) according to the following table:
-
- Original AS400 AS400 AS400 AS400
- file file member type description
- SOURCES Original ZLIB C subprogram sources

-
-4) Continue as in I)3).
-
-
-
-
-Notes: For AS400 ILE RPG programmers, a /copy member defining the ZLIB
- API prototypes for ILE RPG can be found in ZLIB/H(ZLIB.INC).
- Please read comments in this member for more information.
-
- Remember that most foreign textual data are ASCII coded: this
- implementation does not handle conversion from/to ASCII, so
- text data code conversions must be done explicitely.
-
- Mainly for the reason above, always open zipped files in binary mode.

- ZLib for Ada thick binding (ZLib.Ada)
- Release 1.3
-
-ZLib.Ada is a thick binding interface to the popular ZLib data
-compression library, available at http://www.gzip.org/zlib/.
-It provides Ada-style access to the ZLib C library.
-
-
- Here are the main changes since ZLib.Ada 1.2:
-
-- Attension: ZLib.Read generic routine have a initialization requirement
- for Read_Last parameter now. It is a bit incompartible with previous version,
- but extends functionality, we could use new parameters Allow_Read_Some and
- Flush now.
-
-- Added Is_Open routines to ZLib and ZLib.Streams packages.
-
-- Add pragma Assert to check Stream_Element is 8 bit.
-
-- Fix extraction to buffer with exact known decompressed size. Error reported by
- Steve Sangwine.
-
-- Fix definition of ULong (changed to unsigned_long), fix regression on 64 bits
- computers. Patch provided by Pascal Obry.
-
-- Add Status_Error exception definition.
-
-- Add pragma Assertion that Ada.Streams.Stream_Element size is 8 bit.
-
-
- How to build ZLib.Ada under GNAT
-
-You should have the ZLib library already build on your computer, before
-building ZLib.Ada. Make the directory of ZLib.Ada sources current and
-issue the command:
-
- gnatmake test -largs -L<directory where libz.a is> -lz
-
-Or use the GNAT project file build for GNAT 3.15 or later:
-
- gnatmake -Pzlib.gpr -L<directory where libz.a is>
-
-
- How to build ZLib.Ada under Aonix ObjectAda for Win32 7.2.2
-
-1. Make a project with all *.ads and *.adb files from the distribution.
-2. Build the libz.a library from the ZLib C sources.
-3. Rename libz.a to z.lib.
-4. Add the library z.lib to the project.
-5. Add the libc.lib library from the ObjectAda distribution to the project.
-6. Build the executable using test.adb as a main procedure.
-
-
- How to use ZLib.Ada
-
-The source files test.adb and read.adb are small demo programs that show
-the main functionality of ZLib.Ada.
-
-The routines from the package specifications are commented.

-This is a patched version of zlib, modified to use
-Pentium-Pro-optimized assembly code in the deflation algorithm. The
-files changed/added by this patch are:
-
-README.686
-match.S
-
-The speedup that this patch provides varies, depending on whether the
-compiler used to build the original version of zlib falls afoul of the
-PPro's speed traps. My own tests show a speedup of around 10-20% at
-the default compression level, and 20-30% using -9, against a version
-compiled using gcc 2.7.2.3. Your mileage may vary.
-
-Note that this code has been tailored for the PPro/PII in particular,
-and will not perform particuarly well on a Pentium.
-
-If you are using an assembler other than GNU as, you will have to
-translate match.S to use your assembler's syntax. (Have fun.)
-
-Brian Raiter
-breadbox@muppetlabs.com
-April, 1998
-
-
-Added for zlib 1.1.3:
-
-The patches come from
-http://www.muppetlabs.com/~breadbox/software/assembly.html
-
-To compile zlib with this asm file, copy match.S to the zlib directory
-then do:
-
-CFLAGS="-O3 -DASMV" ./configure
-make OBJA=match.o
-
-
-Update:
-
-I've been ignoring these assembly routines for years, believing that
-gcc's generated code had caught up with it sometime around gcc 2.95
-and the major rearchitecting of the Pentium 4. However, I recently
-learned that, despite what I believed, this code still has some life
-in it. On the Pentium 4 and AMD64 chips, it continues to run about 8%
-faster than the code produced by gcc 4.1.
-
-In acknowledgement of its continuing usefulness, I've altered the
-license to match that of the rest of zlib. Share and Enjoy!

- * blast.c decompresses data compressed by the PKWare Compression Library.
- * This function provides functionality similar to the explode() function of
- * the PKWare library, hence the name "blast".
- *
- * This decompressor is based on the excellent format description provided by
- * Ben Rudiak-Gould in comp.compression on August 13, 2001. Interestingly, the
- * example Ben provided in the post is incorrect. The distance 110001 should
- * instead be 111000. When corrected, the example byte stream becomes:
- *
- * 00 04 82 24 25 8f 80 7f
- *
- * which decompresses to "AIAIAIAIAIAIA" (without the quotes).

- * terminated by an end code. Literals are either Huffman coded or
- * uncoded bytes. A length/distance pair is a coded length followed by a
- * coded distance to represent a string that occurs earlier in the
- * uncompressed data that occurs again at the current location.
- *
- * - A bit preceding a literal or length/distance pair indicates which comes
- * next, 0 for literals, 1 for length/distance.
- *
- * - If literals are uncoded, then the next eight bits are the literal, in the
- * normal bit order in th stream, i.e. no bit-reversal is needed. Similarly,
- * no bit reversal is needed for either the length extra bits or the distance
- * extra bits.
- *

- * copy is from distance bytes back in the output stream, copying for length
- * bytes.
- *
- * - Distances pointing before the beginning of the output data are not

- * allowed and common. For example, a distance of one and a length of 518
- * simply copies the last byte 518 times. A distance of four and a length of
- * twelve copies the last four bytes three times. A simple forward copy

- * The input function is invoked: len = infun(how, &buf), where buf is set by

- * The output function is invoked: err = outfun(how, buf, len), where the bytes
- * to be written are buf[0..len-1]. If err is not zero, then blast() returns
- * with an output error. outfun() is always called with len <= 4096. outhow
- * is for use by the application to pass an output descriptor to outfun(), if
- * desired.

- * The return codes are:
- *
- * 2: ran out of input before completing decompression
- * 1: output error before completing decompression
- * 0: successful decompression
- * -1: literal flag not zero or one
- * -2: dictionary size not in 4..6
- * -3: distance is too far back

-Overview
-========
-
-This directory contains an update to the ZLib interface unit,
-distributed by Borland as a Delphi supplemental component.
-
-The original ZLib unit is Copyright (c) 1997,99 Borland Corp.,
-and is based on zlib version 1.0.4. There are a series of bugs
-and security problems associated with that old zlib version, and
-we recommend the users to update their ZLib unit.
-
-
-Summary of modifications
-========================
-
-- Improved makefile, adapted to zlib version 1.2.1.
-
-- Some field types from TZStreamRec are changed from Integer to
- Longint, for consistency with the zlib.h header, and for 64-bit
- readiness.
-
-- The zlib_version constant is updated.
-
-- The new Z_RLE strategy has its corresponding symbolic constant.
-
-- The allocation and deallocation functions and function types
- (TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl,
- and _malloc and _free are added as C RTL stubs. As a result,
- the original C sources of zlib can be compiled out of the box,
- and linked to the ZLib unit.
-
-
-Suggestions for improvements
-============================
-
-Currently, the ZLib unit provides only a limited wrapper around
-the zlib library, and much of the original zlib functionality is
-missing. Handling compressed file formats like ZIP/GZIP or PNG
-cannot be implemented without having this functionality.
-Applications that handle these formats are either using their own,
-duplicated code, or not using the ZLib unit at all.
-
-Here are a few suggestions:
-
-- Checksum class wrappers around adler32() and crc32(), similar
- to the Java classes that implement the java.util.zip.Checksum
- interface.
-
-- The ability to read and write raw deflate streams, without the
- zlib stream header and trailer. Raw deflate streams are used
- in the ZIP file format.
-
-- The ability to read and write gzip streams, used in the GZIP
- file format, and normally produced by the gzip program.
-
-- The ability to select a different compression strategy, useful
- to PNG and MNG image compression, and to multimedia compression
- in general. Besides the compression level
-
- TCompressionLevel = (clNone, clFastest, clDefault, clMax);
-
- which, in fact, could have used the 'z' prefix and avoided
- TColor-like symbols
-
- TCompressionLevel = (zcNone, zcFastest, zcDefault, zcMax);
-
- there could be a compression strategy
-
- TCompressionStrategy = (zsDefault, zsFiltered, zsHuffmanOnly, zsRle);
-
-- ZIP and GZIP stream handling via TStreams.

-This directory contains a .Net wrapper class library for the ZLib1.dll
-
-The wrapper includes support for inflating/deflating memory buffers,
-.Net streaming wrappers for the gz streams part of zlib, and wrappers
-for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples.
-
-Directory structure:
---------------------
-
-LICENSE_1_0.txt - License file.
-readme.txt - This file.
-DotZLib.chm - Class library documentation
-DotZLib.build - NAnt build file
-DotZLib.sln - Microsoft Visual Studio 2003 solution file
-
-DotZLib\*.cs - Source files for the class library
-
-Unit tests:
------------
-The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
-To include unit tests in the build, define nunit before building.
-
-
-Build instructions:
--------------------
-
-1. Using Visual Studio.Net 2003:
- Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
- will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
- you are building the release or debug version of the library. Check
- DotZLib/UnitTests.cs for instructions on how to include unit tests in the
- build.
-
-2. Using NAnt:
- Open a command prompt with access to the build environment and run nant
- in the same directory as the DotZLib.build file.
- You can define 2 properties on the nant command-line to control the build:
- debug={true|false} to toggle between release/debug builds (default=true).
- nunit={true|false} to include or esclude unit tests (default=true).
- Also the target clean will remove binaries.
- Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
- or ./DotZLib/bin/debug, depending on whether you are building the release
- or debug version of the library.
-
- Examples:
- nant -D:debug=false -D:nunit=false
- will build a release mode version of the library without unit tests.
- nant
- will build a debug version of the library with unit tests
- nant clean
- will remove all previously built files.

- in() and out() are the call-back input and output functions. When
- inflateBack() needs more input, it calls in(). When inflateBack() has
- filled the window with output, or when it completes with data in the

- change the provided input until in() is called again or inflateBack()
- returns. The application must not change the window/output buffer until
- inflateBack() returns.
-
- in() and out() are called with a descriptor parameter provided in the

- information required to do the read or write, as well as accumulated
- information on the input and output such as totals and check values.
-
- in() should return zero on failure. out() should return non-zero on
- failure. If either in() or out() fails, than inflateBack() returns a
- Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
- was in() or out() that caused in the error. Otherwise, inflateBack()
- returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
- error, or Z_MEM_ERROR if it could not allocate memory for the state.

- Process a set of code lengths to create a canonical Huffman code. The

- symbols by length from short to long, and retaining the symbol order
- for codes with equal lengths. Then the code starts with all zero bits
- for the first code of the shortest length, and the codes are integer
- increments for the same length, and zeros are appended as the length
- increases. For the deflate format, these bits are stored backwards
- from their more natural integer increment ordering, and so when the
- decoding tables are built in the large loop below, the integer codes
- are incremented backwards.
-
- This routine assumes, but does not check, that all of the entries in
- lens[] are in the range 0..MAXBITS. The caller must assure this.
- 1..MAXBITS is interpreted as that code length. zero means that that

- creating from that a table of starting indices for each length in the
- sorted table, and then entering the symbols in order in the sorted
- table. The sorted table is work[], with that space being provided by
- the caller.
-
- The length counts are used for other purposes as well, i.e. finding

- at length counts to determine sub-table sizes when building the

- * when decompressing mozilla-source-1.3.tar.gz.
- *
- * Mar-13-2003 -- Most of this is derived from inffast.S which is derived from

- Decode literal, length, and distance codes and write out the resulting
- literal and match bytes until either not enough input or output is
- available, an end-of-block is encountered, or a data error is encountered.
- When large enough input and output buffers are supplied to inflate(), for
- example, a 16K input buffer and a 64K output buffer, more than 95% of the
- inflate execution time is spent in this routine.
-
- Entry assumptions:
-
- state->mode == LEN
- strm->avail_in >= 6
- strm->avail_out >= 258
- start >= strm->avail_out
- state->bits < 8
-
- On return, state->mode is one of:
-
- LEN -- ran out of enough output space or enough available input
- TYPE -- reached end of block code, inflate() to interpret next block
- BAD -- error in block data
-
- Notes:
-
- - The maximum input bits used by a length/distance pair is 15 bits for the
- length code, 5 bits for the length extra, 15 bits for the distance code,
- and 13 bits for the distance extra. This totals 48 bits, or six bytes.
- Therefore if strm->avail_in >= 6, then there is enough input to avoid
- checking for available input while decoding.
-
- - The maximum bytes that a single length/distance pair can output is 258
- bytes, which is the maximum length that can be coded. inflate_fast()
- requires strm->avail_out >= 258 for each loop to avoid checking for
- output space.

- * inffast.S is a hand tuned assembler version of:
- *
- * inffast.c -- fast decoding
- * Copyright (C) 1995-2003 Mark Adler
- * For conditions of distribution and use, see copyright notice in zlib.h
- *
- * Copyright (C) 2003 Chris Anderson <christop@charm.net>
- * Please use the copyright conditions above.
- *
- * This version (Jan-23-2003) of inflate_fast was coded and tested under
- * GNU/Linux on a pentium 3, using the gcc-3.2 compiler distribution. On that
- * machine, I found that gzip style archives decompressed about 20% faster than
- * the gcc-3.2 -O3 -fomit-frame-pointer compiled version. Your results will
- * depend on how large of a buffer is used for z_stream.next_in & next_out
- * (8K-32K worked best for my 256K cpu cache) and how much overhead there is in
- * stream processing I/O and crc32/addler32. In my case, this routine used
- * 70% of the cpu time and crc32 used 20%.
- *
- * I am confident that this version will work in the general case, but I have
- * not tested a wide variety of datasets or a wide variety of platforms.
- *
- * Jan-24-2003 -- Added -DUSE_MMX define for slightly faster inflating.
- * It should be a runtime flag instead of compile time flag...
- *
- * Jan-26-2003 -- Added runtime check for MMX support with cpuid instruction.
- * With -DUSE_MMX, only MMX code is compiled. With -DNO_MMX, only non-MMX code
- * is compiled. Without either option, runtime detection is enabled. Runtime
- * detection should work on all modern cpus and the recomended algorithm (flip
- * ID bit on eflags and then use the cpuid instruction) is used in many
- * multimedia applications. Tested under win2k with gcc-2.95 and gas-2.12
- * distributed with cygwin3. Compiling with gcc-2.95 -c inffast.S -o
- * inffast.obj generates a COFF object which can then be linked with MSVC++
- * compiled code. Tested under FreeBSD 4.7 with gcc-2.95.
- *
- * Jan-28-2003 -- Tested Athlon XP... MMX mode is slower than no MMX (and
- * slower than compiler generated code). Adjusted cpuid check to use the MMX
- * code only for Pentiums < P4 until I have more data on the P4. Speed
- * improvment is only about 15% on the Athlon when compared with code generated
- * with MSVC++. Not sure yet, but I think the P4 will also be slower using the
- * MMX mode because many of it's x86 ALU instructions execute in .5 cycles and
- * have less latency than MMX ops. Added code to buffer the last 11 bytes of
- * the input stream since the MMX code grabs bits in chunks of 32, which
- * differs from the inffast.c algorithm. I don't think there would have been
- * read overruns where a page boundary was crossed (a segfault), but there
- * could have been overruns when next_in ends on unaligned memory (unintialized
- * memory read).
- *
- * Mar-13-2003 -- P4 MMX is slightly slower than P4 NO_MMX. I created a C
- * version of the non-MMX code so that it doesn't depend on zstrm and zstate
- * structure offsets which are hard coded in this file. This was last tested
- * with zlib-1.2.0 which is currently in beta testing, newer versions of this
- * and inffas86.c can be found at http://www.eetbeetee.com/zlib/ and
- * http://www.charm.net/~christop/zlib/

-These classes provide a C++ stream interface to the zlib library. It allows you
-to do things like:
-
- gzofstream outf("blah.gz");
- outf << "These go into the gzip file " << 123 << endl;
-
-It does this by deriving a specialized stream buffer for gzipped files, which is
-the way Stroustrup would have done it. :->
-
-The gzifstream and gzofstream classes were originally written by Kevin Ruland
-and made available in the zlib contrib/iostream directory. The older version still
-compiles under gcc 2.xx, but not under gcc 3.xx, which sparked the development of
-this version.
-
-The new classes are as standard-compliant as possible, closely following the
-approach of the standard library's fstream classes. It compiles under gcc versions
-3.2 and 3.3, but not under gcc 2.xx. This is mainly due to changes in the standard
-library naming scheme. The new version of gzifstream/gzofstream/gzfilebuf differs
-from the previous one in the following respects:
-- added showmanyc
-- added setbuf, with support for unbuffered output via setbuf(0,0)
-- a few bug fixes of stream behavior
-- gzipped output file opened with default compression level instead of maximum level
-- setcompressionlevel()/strategy() members replaced by single setcompression()
-
-The code is provided "as is", with the permission to use, copy, modify, distribute
-and sell it for any purpose without fee.

-- The ability to do putback (e.g. putbackfail)
-
-- The ability to seek (zlib supports this, but could be slow/tricky)
-
-- Simultaneous read/write access (does it make sense?)

-- Support for ios_base::ate open mode

- * Dec-29-2003 -- I added AMD64 inflate asm support. This version is also

-/*
- Decode literal, length, and distance codes and write out the resulting
- literal and match bytes until either not enough input or output is
- available, an end-of-block is encountered, or a data error is encountered.
- When large enough input and output buffers are supplied to inflate(), for
- example, a 16K input buffer and a 64K output buffer, more than 95% of the
- inflate execution time is spent in this routine.
-
- Entry assumptions:
-
- state->mode == LEN
- strm->avail_in >= 6
- strm->avail_out >= 258
- start >= strm->avail_out
- state->bits < 8
-
- On return, state->mode is one of:
-
- LEN -- ran out of enough output space or enough available input
- TYPE -- reached end of block code, inflate() to interpret next block
- BAD -- error in block data
-
- Notes:
-
- - The maximum input bits used by a length/distance pair is 15 bits for the
- length code, 5 bits for the length extra, 15 bits for the distance code,
- and 13 bits for the distance extra. This totals 48 bits, or six bytes.
- Therefore if strm->avail_in >= 6, then there is enough input to avoid
- checking for available input while decoding.
-
- - The maximum bytes that a single length/distance pair can output is 258
- bytes, which is the maximum length that can be coded. inflate_fast()
- requires strm->avail_out >= 258 for each loop to avoid checking for
- output space.

-Summary
--------
-This directory contains ASM implementations of the functions
-longest_match() and inflate_fast(), for 64 bits x86 (both AMD64 and Intel EM64t),
-for use with Microsoft Macro Assembler (x64) for AMD64 and Microsoft C++ 64 bits.
-
-gvmat64.asm is written by Gilles Vollant (2005), by using Brian Raiter 686/32 bits
- assembly optimized version from Jean-loup Gailly original longest_match function
-
-inffasx64.asm and inffas8664.c were written by Chris Anderson, by optimizing
- original function from Mark Adler
-
-Use instructions
-----------------
-Assemble the .asm files using MASM and put the object files into the zlib source
-directory. You can also get object files here:
-
- http://www.winimage.com/zLibDll/zlib124_masm_obj.zip
-
-define ASMV and ASMINF in your project. Include inffas8664.c in your source tree,
-and inffasx64.obj and gvmat64.obj as object to link.
-
-
-Build instructions
-------------------
-run bld_64.bat with Microsoft Macro Assembler (x64) for AMD64 (ml64.exe)
-
-ml64.exe is given with Visual Studio 2005, Windows 2003 server DDK
-
-You can get Windows 2003 server DDK with ml64 and cl for AMD64 from
- http://www.microsoft.com/whdc/devtools/ddk/default.mspx for low price)

-; * gcc3.2, icc5.0, msvc6.0. It is very close to the speed of inffast.S
-; * compiled with gcc -DNO_MMX, but inffast.S is still faster on the P3 with MMX
-; * enabled. I will attempt to merge the MMX code into this version. Newer

-MiniZip - Copyright (c) 1998-2010 - by Gilles Vollant - version 1.1 64 bits from Mathias Svensson
-
-Introduction
----------------------
-MiniZip 1.1 is built from MiniZip 1.0 by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )
-
-When adding ZIP64 support into minizip it would result into risk of breaking compatibility with minizip 1.0.
-All possible work was done for compatibility.
-
-
-Background
----------------------
-When adding ZIP64 support Mathias Svensson found that Even Rouault have added ZIP64
-support for unzip.c into minizip for a open source project called gdal ( http://www.gdal.org/ )
-
-That was used as a starting point. And after that ZIP64 support was added to zip.c
-some refactoring and code cleanup was also done.
-
-
-Changed from MiniZip 1.0 to MiniZip 1.1
----------------------------------------
-* Added ZIP64 support for unzip ( by Even Rouault )
-* Added ZIP64 support for zip ( by Mathias Svensson )
-* Reverted some changed that Even Rouault did.
-* Bunch of patches received from Gulles Vollant that he received for MiniZip from various users.
-* Added unzip patch for BZIP Compression method (patch create by Daniel Borca)
-* Added BZIP Compress method for zip
-* Did some refactoring and code cleanup
-
-
-Credits
-
- Gilles Vollant - Original MiniZip author
- Even Rouault - ZIP64 unzip Support
- Daniel Borca - BZip Compression method support in unzip
- Mathias Svensson - ZIP64 zip support
- Mathias Svensson - BZip Compression method support in zip
-
- Resources
-
- ZipLayout http://result42.com/projects/ZipFileLayout
- Command line tool for Windows that shows the layout and information of the headers in a zip archive.
- Used when debugging and validating the creation of zip files using MiniZip64
-
-
- ZIP App Note http://www.pkware.com/documents/casestudies/APPNOTE.TXT
- Zip File specification
-
-
-Notes.
- * To be able to use BZip compression method in zip64.c or unzip64.c the BZIP2 lib is needed and HAVE_BZIP2 need to be defined.

- Version 1.01e, February 12th, 2005
-
- Copyright (C) 1998-2005 Gilles Vollant
-
- This code is a modified version of crypting code in Infozip distribution
-
- The encryption/decryption parts of this source code (as opposed to the
- non-echoing password parts) were originally written in Europe. The
- whole source package can be freely distributed, including from the USA.
- (Prior to January 2000, re-export from the US was a violation of US law.)
-
- This encryption code is a direct transcription of the algorithm from
- Roger Schlafly, described by Phil Katz in the file appnote.txt. This
- file (appnote.txt) is distributed with the PKZIP program (even in the
- version without encryption capabilities).
-
- If you don't need crypting in your application, just define symbols
- NOCRYPT and NOUNCRYPT.
-
- This code support the "Traditional PKWARE Encryption".
-
- The new AES encryption added on Zip format by Winzip (see the page
- http://www.winzip.com/aes_info.htm ) and PKWare PKZip 5.x Strong
- Encryption is not supported.

- Changes
-
- Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
- Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
- More if/def section may be needed to support other platforms
- Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
- (but you should use iowin32.c for windows instead)

- For more info read MiniZip_info.txt

-
- ------------------------------------------------------------------------------------
- Decryption code comes from crypt.c by Info-ZIP but has been greatly reduced in terms of
- compatibility with older software. The following is from the original crypt.c.
- Code woven in by Terry Thorsen 1/2003.
-
- Copyright (c) 1990-2000 Info-ZIP. All rights reserved.

- See the accompanying file LICENSE, version 2000-Apr-09 or later

- If, for some reason, all these files are missing, the Info-ZIP license
- also may be found at: ftp://ftp.info-zip.org/pub/infozip/license.html
-
- crypt.c (full version) by Info-ZIP. Last revised: [see crypt.h]
-
- The encryption/decryption parts of this source code (as opposed to the
- non-echoing password parts) were originally written in Europe. The
- whole source package can be freely distributed, including from the USA.
- (Prior to January 2000, re-export from the US was a violation of US law.)
-
- This encryption code is a direct transcription of the algorithm from
- Roger Schlafly, described by Phil Katz in the file appnote.txt. This
- file (appnote.txt) is distributed with the PKZIP program (even in the
- version without encryption capabilities).
-
- ------------------------------------------------------------------------------------
-
- Changes in unzip.c
-
- 2007-2008 - Even Rouault - Addition of cpl_unzGetCurrentFileZStreamPos
- 2007-2008 - Even Rouault - Decoration of symbol names unz* -> cpl_unz*
- 2007-2008 - Even Rouault - Remove old C style function prototypes
- 2007-2008 - Even Rouault - Add unzip support for ZIP64
-
- Copyright (C) 2007-2008 Even Rouault
-
-
- Oct-2009 - Mathias Svensson - Removed cpl_* from symbol names (Even Rouault added them but since this is now moved to a new project (minizip64) I renamed them again).
- Oct-2009 - Mathias Svensson - Fixed problem if uncompressed size was > 4G and compressed size was <4G
- should only read the compressed/uncompressed size from the Zip64 format if
- the size from normal header was 0xFFFFFFFF
- Oct-2009 - Mathias Svensson - Applied some bug fixes from paches recived from Gilles Vollant
- Oct-2009 - Mathias Svensson - Applied support to unzip files with compression mathod BZIP2 (bzip2 lib is required)
- Patch created by Daniel Borca
-
- Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

- Changes
- Oct-2009 - Mathias Svensson - Remove old C style function prototypes
- Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives
- Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions.
- Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data
- It is used when recreting zip archive with RAW when deleting items from a zip.
- ZIP64 data is automaticly added to items that needs it, and existing ZIP64 data need to be removed.
- Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
- Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

-
-
-Compatibility notes
-===================
-
-- Although the name "zlib" would have been more normal for the
- zlibpas unit, this name is already taken by Borland's ZLib unit.
- This is somehow unfortunate, because that unit is not a genuine
- interface to the full-fledged zlib functionality, but a suite of
- class wrappers around zlib streams. Other essential features,
- such as checksums, are missing.
- It would have been more appropriate for that unit to have a name
- like "ZStreams", or something similar.
-
-- The C and zlib-supplied types int, uInt, long, uLong, etc. are
- translated directly into Pascal types of similar sizes (Integer,
- LongInt, etc.), to avoid namespace pollution. In particular,
- there is no conversion of unsigned int into a Pascal unsigned
- integer. The Word type is non-portable and has the same size
- (16 bits) both in a 16-bit and in a 32-bit environment, unlike
- Integer. Even if there is a 32-bit Cardinal type, there is no
- real need for unsigned int in zlib under a 32-bit environment.
-
-- Except for the callbacks, the zlib function interfaces are
- assuming the calling convention normally used in Pascal
- (__pascal for DOS and Windows16, __fastcall for Windows32).
- Since the cdecl keyword is used, the old Turbo Pascal does
- not work with this interface.
-
-- The gz* function interfaces are not translated, to avoid
- interfacing problems with the C runtime library. Besides,
- gzprintf(gzFile file, const char *format, ...)
- cannot be translated into Pascal.

-Puff -- A Simple Inflate
-3 Mar 2003
-Mark Adler
-madler@alumni.caltech.edu
-
-What this is --
-
-puff.c provides the routine puff() to decompress the deflate data format. It
-does so more slowly than zlib, but the code is about one-fifth the size of the
-inflate code in zlib, and written to be very easy to read.
-
-Why I wrote this --
-
-puff.c was written to document the deflate format unambiguously, by virtue of
-being working C code. It is meant to supplement RFC 1951, which formally
-describes the deflate format. I have received many questions on details of the
-deflate format, and I hope that reading this code will answer those questions.
-puff.c is heavily commented with details of the deflate format, especially
-those little nooks and cranies of the format that might not be obvious from a
-specification.
-
-puff.c may also be useful in applications where code size or memory usage is a
-very limited resource, and speed is not as important.
-
-How to use it --
-
-Well, most likely you should just be reading puff.c and using zlib for actual
-applications, but if you must ...
-
-Include puff.h in your code, which provides this prototype:
-
-int puff(unsigned char *dest, /* pointer to destination pointer */
- unsigned long *destlen, /* amount of output space */
- unsigned char *source, /* pointer to source data pointer */
- unsigned long *sourcelen); /* amount of input available */
-
-Then you can call puff() to decompress a deflate stream that is in memory in
-its entirety at source, to a sufficiently sized block of memory for the
-decompressed data at dest. puff() is the only external symbol in puff.c The
-only C library functions that puff.c needs are setjmp() and longjmp(), which
-are used to simplify error checking in the code to improve readabilty. puff.c
-does no memory allocation, and uses less than 2K bytes off of the stack.
-
-If destlen is not enough space for the uncompressed data, then inflate will
-return an error without writing more than destlen bytes. Note that this means
-that in order to decompress the deflate data successfully, you need to know
-the size of the uncompressed data ahead of time.
-
-If needed, puff() can determine the size of the uncompressed data with no
-output space. This is done by passing dest equal to (unsigned char *)0. Then
-the initial value of *destlen is ignored and *destlen is set to the length of
-the uncompressed data. So if the size of the uncompressed data is not known,
-then two passes of puff() can be used--first to determine the size, and second
-to do the actual inflation after allocating the appropriate memory. Not
-pretty, but it works. (This is one of the reasons you should be using zlib.)
-
-The deflate format is self-terminating. If the deflate stream does not end
-in *sourcelen bytes, puff() will return an error without reading at or past
-endsource.
-
-On return, *sourcelen is updated to the amount of input data consumed, and
-*destlen is updated to the size of the uncompressed data. See the comments
-in puff.c for the possible return codes for puff().

- *
- * puff.c is a simple inflate written to be an unambiguous way to specify the
- * deflate format. It is not written for speed but rather simplicity. As a
- * side benefit, this code might actually be useful when small code is more
- * important than speed, such as bootstrap applications. For typical deflate
- * data, zlib's inflate() is about four times as fast as puff(). zlib's
- * inflate compiles to around 20K on my machine, whereas puff.c compiles to
- * around 4K on my machine (a PowerPC using GNU cc). If the faster decode()
- * function here is used, then puff() is only twice as slow as zlib's
- * inflate().
- *
- * All dynamically allocated memory comes from the stack. The stack required
- * is less than 2K bytes. This code is compatible with 16-bit int's and
- * assumes that long's are at least 32 bits. puff.c uses the short data type,
- * assumed to be 16 bits, for arrays in order to to conserve memory. The code
- * works whether integers are stored big endian or little endian.
- *
- * In the comments below are "Format notes" that describe the inflate process
- * and document some of the less obvious aspects of the format. This source
- * code is meant to supplement RFC 1951, which formally describes the deflate
- * format:

- * Decode literal/length and distance codes until an end-of-block code.
- *
- * Format notes:
- *
- * - Compressed data that is after the block type if fixed or after the code
- * description if dynamic is a combination of literals and length/distance
- * pairs terminated by and end-of-block code. Literals are simply Huffman
- * coded bytes. A length/distance pair is a coded length followed by a
- * coded distance to represent a string that occurs earlier in the
- * uncompressed data that occurs again at the current location.
- *
- * - Literals, lengths, and the end-of-block code are combined into a single
- * code of up to 286 symbols. They are 256 literals (0..255), 29 length
- * symbols (257..285), and the end-of-block symbol (256).
- *
- * - There are 256 possible lengths (3..258), and so 29 symbols are not enough
- * to represent all of those. Lengths 3..10 and 258 are in fact represented
- * by just a length symbol. Lengths 11..257 are represented as a symbol and
- * some number of extra bits that are added as an integer to the base length
- * of the length symbol. The number of extra bits is determined by the base
- * length symbol. These are in the static arrays below, lens[] for the base
- * lengths and lext[] for the corresponding number of extra bits.
- *
- * - The reason that 258 gets its own symbol is that the longest length is used
- * often in highly redundant files. Note that 258 can also be coded as the
- * base value 227 plus the maximum extra value of 31. While a good deflate
- * should never do this, it is not an error, and should be decoded properly.
- *
- * - If a length is decoded, including its extra bits if any, then it is
- * followed a distance code. There are up to 30 distance symbols. Again
- * there are many more possible distances (1..32768), so extra bits are added
- * to a base value represented by the symbol. The distances 1..4 get their
- * own symbol, but the rest require extra bits. The base distances and
- * corresponding number of extra bits are below in the static arrays dist[]
- * and dext[].
- *
- * - Literal bytes are simply written to the output. A length/distance pair is
- * an instruction to copy previously uncompressed bytes to the output. The
- * copy is from distance bytes back in the output stream, copying for length
- * bytes.
- *
- * - Distances pointing before the beginning of the output data are not
- * permitted.
- *
- * - Overlapped copies, where the length is greater than the distance, are
- * allowed and common. For example, a distance of one and a length of 258
- * simply copies the last byte 258 times. A distance of four and a length of
- * twelve copies the last four bytes three times. A simple forward copy
- * ignoring whether the length is greater than the distance or not implements
- * this correctly. You should not use memcpy() since its behavior is not
- * defined for overlapped arrays. You should not use memmove() or bcopy()
- * since though their behavior -is- defined for overlapping arrays, it is
- * defined to do the wrong thing in this case.

- * - This block type can be useful for compressing small amounts of data for
- * which the size of the code descriptions in a dynamic block exceeds the
- * benefit of custom codes for that block. For fixed codes, no bits are
- * spent on code descriptions. Instead the code lengths for literal/length
- * codes and distance codes are fixed. The specific lengths for each symbol
- * can be seen in the "for" loops below.
- *
- * - The literal/length code is complete, but has two symbols that are invalid
- * and should result in an error if received. This cannot be implemented
- * simply as an incomplete code since those two symbols are in the "middle"
- * of the code. They are eight bits long and the longest literal/length\
- * code is nine bits. Therefore the code must be constructed with those
- * symbols, and the invalid symbols must be detected after decoding.
- *
- * - The fixed distance codes also have two invalid symbols that should result
- * in an error if received. Since all of the distance codes are the same
- * length, this can be implemented as an incomplete code. Then the invalid
- * codes are detected while decoding.

- * Process a dynamic codes block.
- *
- * Format notes:
- *
- * - A dynamic block starts with a description of the literal/length and
- * distance codes for that block. New dynamic blocks allow the compressor to
- * rapidly adapt to changing data with new codes optimized for that data.
- *
- * - The codes used by the deflate format are "canonical", which means that
- * the actual bits of the codes are generated in an unambiguous way simply
- * from the number of bits in each code. Therefore the code descriptions
- * are simply a list of code lengths for each symbol.
- *
- * - The code lengths are stored in order for the symbols, so lengths are
- * provided for each of the literal/length symbols, and for each of the
- * distance symbols.
- *
- * - If a symbol is not used in the block, this is represented by a zero as
- * as the code length. This does not mean a zero-length code, but rather
- * that no code should be created for this symbol. There is no way in the
- * deflate format to represent a zero-length code.
- *
- * - The maximum number of bits in a code is 15, so the possible lengths for
- * any code are 1..15.
- *
- * - The fact that a length of zero is not permitted for a code has an
- * interesting consequence. Normally if only one symbol is used for a given
- * code, then in fact that code could be represented with zero bits. However
- * in deflate, that code has to be at least one bit. So for example, if
- * only a single distance base symbol appears in a block, then it will be
- * represented by a single code of length one, in particular one 0 bit. This
- * is an incomplete code, since if a 1 bit is received, it has no meaning,
- * and should result in an error. So incomplete distance codes of one symbol
- * should be permitted, and the receipt of invalid codes should be handled.
- *
- * - It is also possible to have a single literal/length code, but that code
- * must be the end-of-block code, since every dynamic block has one. This
- * is not the most efficient way to create an empty block (an empty fixed
- * block is fewer bits), but it is allowed by the format. So incomplete
- * literal/length codes of one symbol should also be permitted.
- *
- * - If there are only literal codes and no lengths, then there are no distance
- * codes. This is represented by one distance code with zero bits.
- *
- * - The list of up to 286 length/literal lengths and up to 30 distance lengths
- * are themselves compressed using Huffman codes and run-length encoding. In
- * the list of code lengths, a 0 symbol means no code, a 1..15 symbol means
- * that length, and the symbols 16, 17, and 18 are run-length instructions.
- * Each of 16, 17, and 18 are follwed by extra bits to define the length of
- * the run. 16 copies the last length 3 to 6 times. 17 represents 3 to 10
- * zero lengths, and 18 represents 11 to 138 zero lengths. Unused symbols
- * are common, hence the special coding for zero lengths.
- *
- * - The symbols for 0..18 are Huffman coded, and so that code must be
- * described first. This is simply a sequence of up to 19 three-bit values
- * representing no code (0) or the code length for that symbol (1..7).
- *
- * - A dynamic block starts with three fixed-size counts from which is computed
- * the number of literal/length code lengths, the number of distance code
- * lengths, and the number of code length code lengths (ok, you come up with
- * a better name!) in the code descriptions. For the literal/length and
- * distance codes, lengths after those provided are considered zero, i.e. no
- * code. The code length code lengths are received in a permuted order (see
- * the order[] array below) to make a short code length code length list more
- * likely. As it turns out, very short and very long codes are less likely
- * to be seen in a dynamic code description, hence what may appear initially
- * to be a peculiar ordering.
- *
- * - Given the number of literal/length code lengths (nlen) and distance code
- * lengths (ndist), then they are treated as one long list of nlen + ndist
- * code lengths. Therefore run-length coding can and often does cross the
- * boundary between the two sets of lengths.
- *
- * - So to summarize, the code description at the start of a dynamic block is
- * three counts for the number of code lengths for the literal/length codes,
- * the distance codes, and the code length codes. This is followed by the
- * code length code lengths, three bits each. This is used to construct the
- * code length code which is used to read the remainder of the lengths. Then
- * the literal/length code lengths and distance lengths are read as a single
- * set of lengths using the code length codes. Codes are constructed from
- * the resulting two sets of lengths, and then finally you can start
- * decoding actual compressed data in the block.
- *
- * - For reference, a "typical" size for the code description in a dynamic
- * block is around 80 bytes.

- Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
- x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
-
- Polynomials over GF(2) are represented in binary, one bit per coefficient,
- with the lowest powers in the most significant bit. Then adding polynomials
- is just exclusive-or, and multiplying a polynomial by x is a right shift by
- one. If we call the above polynomial p, and represent a byte as the
- polynomial q, also with the lowest power in the most significant bit (so the
- byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
- where a mod b means the remainder after dividing a by b.
-
- This calculation is done using the shift-register method of multiplying and
- taking the remainder. The register is initialized to zero, and for each
- incoming bit, x^32 is added mod p to the register if the bit is a one (where
- x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
- x (which is shifting right by one and adding x^32 mod p if the bit shifted
- out is a one). We start with the highest power (least significant bit) of
- q and repeat for all eight bits of q.
-
- The first table is simply the CRC of all possible eight bit values. This is
- all the information needed to generate CRCs on data a byte at a time for all
- combinations of CRC register values and incoming bytes. The remaining tables
- allow for word-at-a-time CRC calculation for both big-endian and little-
- endian machines, where a word is four bytes.

-/*
- * ALGORITHM
- *
- * The "deflation" process depends on being able to identify portions
- * of the input text which are identical to earlier input (within a
- * sliding window trailing behind the input currently being processed).
- *
- * The most straightforward technique turns out to be the fastest for
- * most input files: try all possible matches and select the longest.
- * The key feature of this algorithm is that insertions into the string
- * dictionary are very simple and thus fast, and deletions are avoided
- * completely. Insertions are performed at each input character, whereas
- * string matches are performed only when the previous match ends. So it
- * is preferable to spend more time in matches to allow very fast string
- * insertions and avoid deletions. The matching algorithm for small
- * strings is inspired from that of Rabin & Karp. A brute force approach
- * is used to find longer strings when a small match has been found.
- * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
- * (by Leonid Broukhis).
- * A previous version of this file used a more sophisticated algorithm
- * (by Fiala and Greene) which is guaranteed to run in linear amortized
- * time, but has a larger average cost, uses more memory and is patented.
- * However the F&G algorithm may be faster for some highly redundant
- * files if the parameter max_chain_length (described below) is too large.
- *
- * ACKNOWLEDGEMENTS
- *
- * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
- * I found it in 'freeze' written by Leonid Broukhis.
- * Thanks to many people for bug reports and testing.

-1. Compression algorithm (deflate)
-
-The deflation algorithm used by gzip (also zip and zlib) is a variation of
-LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in
-the input data. The second occurrence of a string is replaced by a
-pointer to the previous string, in the form of a pair (distance,
-length). Distances are limited to 32K bytes, and lengths are limited
-to 258 bytes. When a string does not occur anywhere in the previous
-32K bytes, it is emitted as a sequence of literal bytes. (In this
-description, `string' must be taken as an arbitrary sequence of bytes,
-and is not restricted to printable characters.)
-
-Literals or match lengths are compressed with one Huffman tree, and
-match distances are compressed with another tree. The trees are stored
-in a compact form at the start of each block. The blocks can have any
-size (except that the compressed data for one block must fit in
-available memory). A block is terminated when deflate() determines that
-it would be useful to start another block with fresh trees. (This is
-somewhat similar to the behavior of LZW-based _compress_.)
-
-Duplicated strings are found using a hash table. All input strings of
-length 3 are inserted in the hash table. A hash index is computed for
-the next 3 bytes. If the hash chain for this index is not empty, all
-strings in the chain are compared with the current input string, and
-the longest match is selected.
-
-The hash chains are searched starting with the most recent strings, to
-favor small distances and thus take advantage of the Huffman encoding.
-The hash chains are singly linked. There are no deletions from the
-hash chains, the algorithm simply discards matches that are too old.
-
-To avoid a worst-case situation, very long hash chains are arbitrarily
-truncated at a certain length, determined by a runtime option (level
-parameter of deflateInit). So deflate() does not always find the longest
-possible match but generally finds a match which is long enough.
-
-deflate() also defers the selection of matches with a lazy evaluation
-mechanism. After a match of length N has been found, deflate() searches for
-a longer match at the next input byte. If a longer match is found, the
-previous match is truncated to a length of one (thus producing a single
-literal byte) and the process of lazy evaluation begins again. Otherwise,
-the original match is kept, and the next match search is attempted only N
-steps later.
-
-The lazy match evaluation is also subject to a runtime parameter. If
-the current match is long enough, deflate() reduces the search for a longer
-match, thus speeding up the whole process. If compression ratio is more
-important than speed, deflate() attempts a complete second search even if
-the first match is already long enough.
-
-The lazy match evaluation is not performed for the fastest compression
-modes (level parameter 1 to 3). For these fast modes, new strings
-are inserted in the hash table only when no match was found, or
-when the match is not too long. This degrades the compression ratio
-but saves time since there are both fewer insertions and fewer searches.
-
-
-2. Decompression algorithm (inflate)
-
-2.1 Introduction
-
-The key question is how to represent a Huffman code (or any prefix code) so
-that you can decode fast. The most important characteristic is that shorter
-codes are much more common than longer codes, so pay attention to decoding the
-short codes fast, and let the long codes take longer to decode.
-
-inflate() sets up a first level table that covers some number of bits of
-input less than the length of longest code. It gets that many bits from the
-stream, and looks it up in the table. The table will tell if the next
-code is that many bits or less and how many, and if it is, it will tell
-the value, else it will point to the next level table for which inflate()
-grabs more bits and tries to decode a longer code.
-
-How many bits to make the first lookup is a tradeoff between the time it
-takes to decode and the time it takes to build the table. If building the
-table took no time (and if you had infinite memory), then there would only
-be a first level table to cover all the way to the longest code. However,
-building the table ends up taking a lot longer for more bits since short
-codes are replicated many times in such a table. What inflate() does is
-simply to make the number of bits in the first table a variable, and then
-to set that variable for the maximum speed.
-
-For inflate, which has 286 possible codes for the literal/length tree, the size
-of the first table is nine bits. Also the distance trees have 30 possible
-values, and the size of the first table is six bits. Note that for each of
-those cases, the table ended up one bit longer than the ``average'' code
-length, i.e. the code length of an approximately flat code which would be a
-little more than eight bits for 286 symbols and a little less than five bits
-for 30 symbols.
-
-
-2.2 More details on the inflate table lookup
-
-Ok, you want to know what this cleverly obfuscated inflate tree actually
-looks like. You are correct that it's not a Huffman tree. It is simply a
-lookup table for the first, let's say, nine bits of a Huffman symbol. The
-symbol could be as short as one bit or as long as 15 bits. If a particular
-symbol is shorter than nine bits, then that symbol's translation is duplicated
-in all those entries that start with that symbol's bits. For example, if the
-symbol is four bits, then it's duplicated 32 times in a nine-bit table. If a
-symbol is nine bits long, it appears in the table once.
-
-If the symbol is longer than nine bits, then that entry in the table points
-to another similar table for the remaining bits. Again, there are duplicated
-entries as needed. The idea is that most of the time the symbol will be short
-and there will only be one table look up. (That's whole idea behind data
-compression in the first place.) For the less frequent long symbols, there
-will be two lookups. If you had a compression method with really long
-symbols, you could have as many levels of lookups as is efficient. For
-inflate, two is enough.
-
-So a table entry either points to another table (in which case nine bits in
-the above example are gobbled), or it contains the translation for the symbol
-and the number of bits to gobble. Then you start again with the next
-ungobbled bit.
-
-You may wonder: why not just have one lookup table for how ever many bits the
-longest symbol is? The reason is that if you do that, you end up spending
-more time filling in duplicate symbol entries than you do actually decoding.
-At least for deflate's output that generates new trees every several 10's of
-kbytes. You can imagine that filling in a 2^15 entry table for a 15-bit code
-would take too long if you're only decoding several thousand symbols. At the
-other extreme, you could make a new table for every bit in the code. In fact,
-that's essentially a Huffman tree. But then you spend too much time
-traversing the tree while decoding, even for short symbols.
-
-So the number of bits for the first lookup table is a trade of the time to
-fill out the table vs. the time spent looking at the second level and above of
-the table.
-
-Here is an example, scaled down:
-
-The code being decoded, with 10 symbols, from 1 to 6 bits long:
-
-A: 0
-B: 10
-C: 1100
-D: 11010
-E: 11011
-F: 11100
-G: 11101
-H: 11110
-I: 111110
-J: 111111
-
-Let's make the first table three bits long (eight entries):
-
-000: A,1
-001: A,1
-010: A,1
-011: A,1
-100: B,2
-101: B,2
-110: -> table X (gobble 3 bits)
-111: -> table Y (gobble 3 bits)
-
-Each entry is what the bits decode as and how many bits that is, i.e. how
-many bits to gobble. Or the entry points to another table, with the number of
-bits to gobble implicit in the size of the table.
-
-Table X is two bits long since the longest code starting with 110 is five bits
-long:
-
-00: C,1
-01: C,1
-10: D,2
-11: E,2
-
-Table Y is three bits long since the longest code starting with 111 is six
-bits long:
-
-000: F,2
-001: F,2
-010: G,2
-011: G,2
-100: H,2
-101: H,2
-110: I,3
-111: J,3
-
-So what we have here are three tables with a total of 20 entries that had to
-be constructed. That's compared to 64 entries for a single table. Or
-compared to 16 entries for a Huffman tree (six two entry tables and one four
-entry table). Assuming that the code ideally represents the probability of
-the symbols, it takes on the average 1.25 lookups per symbol. That's compared
-to one lookup for the single table, or 1.66 lookups per symbol for the
-Huffman tree.
-
-There, I think that gives you a picture of what's going on. For inflate, the
-meaning of a particular symbol is often more than just a letter. It can be a
-byte (a "literal"), or it can be either a length or a distance which
-indicates a base value and a number of bits to fetch after the code that is
-added to the base value. Or it might be the special end-of-block code. The
-data structures created in inftrees.c try to encode all that information
-compactly in the tables.

-
- This specification defines a lossless compressed data format. The
- data can be produced or consumed, even for an arbitrarily long
- sequentially presented input data stream, using only an a priori
- bounded amount of intermediate storage. The format presently uses
- the DEFLATE compression method but can be easily extended to use
- other compression methods. It can be implemented readily in a manner
- not covered by patents. This specification also defines the ADLER-32
- checksum (an extension and improvement of the Fletcher checksum),
- used for detection of data corruption, and provides an algorithm for
- computing it.

-1. Introduction
-
- 1.1. Purpose
-
- The purpose of this specification is to define a lossless
- compressed data format that:
-
- * Is independent of CPU type, operating system, file system,
- and character set, and hence can be used for interchange;
-
- * Can be produced or consumed, even for an arbitrarily long
- sequentially presented input data stream, using only an a
- priori bounded amount of intermediate storage, and hence can
- be used in data communications or similar structures such as
- Unix filters;
-
- * Can use a number of different compression methods;
-
- * Can be implemented readily in a manner not covered by
- patents, and hence can be practiced freely.
-
- The data format defined by this specification does not attempt to
- allow random access to compressed data.

-RFC 1950 ZLIB Compressed Data Format Specification May 1996
-
-
- 1.2. Intended audience
-
- This specification is intended for use by implementors of software
- to compress data into zlib format and/or decompress data from zlib
- format.
-
- The text of the specification assumes a basic background in
- programming at the level of bits and other primitive data
- representations.
-
- 1.3. Scope
-
- The specification specifies a compressed data format that can be
- used for in-memory compression of a sequence of arbitrary bytes.
-
- 1.4. Compliance
-
- Unless otherwise indicated below, a compliant decompressor must be
- able to accept and decompress any data set that conforms to all
- the specifications presented here; a compliant compressor must
- produce data sets that conform to all the specifications presented
- here.
-
- 1.5. Definitions of terms and conventions used
-
- byte: 8 bits stored or transmitted as a unit (same as an octet).
- (For this specification, a byte is exactly 8 bits, even on
- machines which store a character on a number of bits different
- from 8.) See below, for the numbering of bits within a byte.
-
- 1.6. Changes from previous versions
-
- Version 3.1 was the first public release of this specification.
- In version 3.2, some terminology was changed and the Adler-32
- sample code was rewritten for clarity. In version 3.3, the
- support for a preset dictionary was introduced, and the
- specification was converted to RFC style.
-
-2. Detailed specification
-
- 2.1. Overall conventions
-
- In the diagrams below, a box like this:

- | | <-- the vertical bars might be missing
- +---+
-
-
-
-
-Deutsch & Gailly Informational [Page 3]
-
-RFC 1950 ZLIB Compressed Data Format Specification May 1996
-
-
- represents one byte; a box like this:
-
- +==============+
- | |
- +==============+
-
- represents a variable number of bytes.
-
- Bytes stored within a computer do not have a "bit order", since
- they are always treated as a unit. However, a byte considered as
- an integer between 0 and 255 does have a most- and least-
- significant bit, and since we write numbers with the most-
- significant digit on the left, we also write bytes with the most-
- significant bit on the left. In the diagrams below, we number the
- bits of a byte so that bit 0 is the least-significant bit, i.e.,
- the bits are numbered:
-
- +--------+
- |76543210|
- +--------+
-
- Within a computer, a number may occupy multiple bytes. All
- multi-byte numbers in the format described here are stored with
- the MOST-significant byte first (at the lower memory address).
- For example, the decimal number 520 is stored as:
-
- 0 1
- +--------+--------+
- |00000010|00001000|
- +--------+--------+
- ^ ^
- | |
- | + less significant byte = 8
- + more significant byte = 2 x 256
-
- 2.2. Data format

- This identifies the compression method used in the file. CM = 8
- denotes the "deflate" compression method with a window size up
- to 32K. This is the method used by gzip and PNG (see
- references [1] and [2] in Chapter 3, below, for the reference
- documents). CM = 15 is reserved. It might be used in a future
- version of this specification to indicate the presence of an
- extra field before the compressed data.
-
- CINFO (Compression info)
- For CM = 8, CINFO is the base-2 logarithm of the LZ77 window
- size, minus eight (CINFO=7 indicates a 32K window size). Values
- of CINFO above 7 are not allowed in this version of the
- specification. CINFO is not defined in this specification for
- CM not equal to 8.
-
- FLG (FLaGs)
- This flag byte is divided as follows:
-
- bits 0 to 4 FCHECK (check bits for CMF and FLG)
- bit 5 FDICT (preset dictionary)
- bits 6 to 7 FLEVEL (compression level)
-
- The FCHECK value must be such that CMF and FLG, when viewed as
- a 16-bit unsigned integer stored in MSB order (CMF*256 + FLG),
- is a multiple of 31.

-
-
- FDICT (Preset dictionary)
- If FDICT is set, a DICT dictionary identifier is present
- immediately after the FLG byte. The dictionary is a sequence of
- bytes which are initially fed to the compressor without
- producing any compressed output. DICT is the Adler-32 checksum
- of this sequence of bytes (see the definition of ADLER32
- below). The decompressor can use this identifier to determine
- which dictionary has been used by the compressor.
-
- FLEVEL (Compression level)
- These flags are available for use by specific compression
- methods. The "deflate" method (CM = 8) sets these flags as
- follows:
-
- 0 - compressor used fastest algorithm
- 1 - compressor used fast algorithm
- 2 - compressor used default algorithm
- 3 - compressor used maximum compression, slowest algorithm
-
- The information in FLEVEL is not needed for decompression; it
- is there to indicate if recompression might be worthwhile.
-
- compressed data
- For compression method 8, the compressed data is stored in the
- deflate compressed data format as described in the document
- "DEFLATE Compressed Data Format Specification" by L. Peter
- Deutsch. (See reference [3] in Chapter 3, below)
-
- Other compressed data formats are not specified in this version
- of the zlib specification.
-
- ADLER32 (Adler-32 checksum)
- This contains a checksum value of the uncompressed data
- (excluding any dictionary data) computed according to Adler-32
- algorithm. This algorithm is a 32-bit extension and improvement
- of the Fletcher algorithm, used in the ITU-T X.224 / ISO 8073
- standard. See references [4] and [5] in Chapter 3, below)
-
- Adler-32 is composed of two sums accumulated per byte: s1 is
- the sum of all bytes, s2 is the sum of all s1 values. Both sums
- are done modulo 65521. s1 is initialized to 1, s2 to zero. The
- Adler-32 checksum is stored as s2*65536 + s1 in most-
- significant-byte first (network) order.

-
- 2.3. Compliance
-
- A compliant compressor must produce streams with correct CMF, FLG
- and ADLER32, but need not support preset dictionaries. When the
- zlib data format is used as part of another standard data format,
- the compressor may use only preset dictionaries that are specified
- by this other data format. If this other format does not use the
- preset dictionary feature, the compressor must not set the FDICT
- flag.
-
- A compliant decompressor must check CMF, FLG, and ADLER32, and
- provide an error indication if any of these have incorrect values.
- A compliant decompressor must give an error indication if CM is
- not one of the values defined in this specification (only the
- value 8 is permitted in this version), since another value could
- indicate the presence of new features that would cause subsequent
- data to be interpreted incorrectly. A compliant decompressor must
- give an error indication if FDICT is set and DICTID is not the
- identifier of a known preset dictionary. A decompressor may
- ignore FLEVEL and still be compliant. When the zlib data format
- is being used as a part of another standard format, a compliant
- decompressor must support all the preset dictionaries specified by
- the other format. When the other format does not use the preset
- dictionary feature, a compliant decompressor must reject any
- stream in which the FDICT flag is set.

-8. Appendix: Rationale
-
- 8.1. Preset dictionaries
-
- A preset dictionary is specially useful to compress short input
- sequences. The compressor can take advantage of the dictionary
- context to encode the input in a more compact manner. The
- decompressor can be initialized with the appropriate context by
- virtually decompressing a compressed version of the dictionary
- without producing any output. However for certain compression
- algorithms such as the deflate algorithm this operation can be
- achieved without actually performing any decompression.
-
- The compressor and the decompressor must use exactly the same
- dictionary. The dictionary may be fixed or may be chosen among a
- certain number of predefined dictionaries, according to the kind
- of input data. The decompressor can determine which dictionary has
- been chosen by the compressor by checking the dictionary
- identifier. This document does not specify the contents of
- predefined dictionaries, since the optimal dictionaries are
- application specific. Standard data formats using this feature of
- the zlib specification must precisely define the allowed
- dictionaries.
-
- 8.2. The Adler-32 algorithm
-
- The Adler-32 algorithm is much faster than the CRC32 algorithm yet
- still provides an extremely low probability of undetected errors.
-
- The modulo on unsigned long accumulators can be delayed for 5552
- bytes, so the modulo operation time is negligible. If the bytes
- are a, b, c, the second sum is 3a + 2b + c + 3, and so is position
- and order sensitive, unlike the first sum, which is just a
- checksum. That 65521 is prime is important to avoid a possible
- large class of two-byte errors that leave the check unchanged.
- (The Fletcher checksum uses 255, which is not prime and which also
- makes the Fletcher check insensitive to single byte changes 0 <->
- 255.)
-
- The sum s1 is initialized to 1 instead of zero to make the length
- of the sequence part of s2, so that the length does not have to be
- checked separately. (Any sequence of zeroes has a Fletcher
- checksum of zero.)

-9. Appendix: Sample code
-
- The following C code computes the Adler-32 checksum of a data buffer.
- It is written for clarity, not for speed. The sample code is in the
- ANSI C programming language. Non C users may find it easier to read
- with these hints:
-
- & Bitwise AND operator.
- >> Bitwise right shift operator. When applied to an
- unsigned quantity, as here, right shift inserts zero bit(s)
- at the left.
- << Bitwise left shift operator. Left shift inserts zero
- bit(s) at the right.
- ++ "n++" increments the variable n.
- % modulo operator: a % b is the remainder of a divided by b.
-
- #define BASE 65521 /* largest prime smaller than 65536 */
-
- /*
- Update a running Adler-32 checksum with the bytes buf[0..len-1]
- and return the updated checksum. The Adler-32 checksum should be
- initialized to 1.
-
- Usage example:
-
- unsigned long adler = 1L;
-
- while (read_buffer(buffer, length) != EOF) {
- adler = update_adler32(adler, buffer, length);
- }
- if (adler != original_adler) error();
- */
- unsigned long update_adler32(unsigned long adler,
- unsigned char *buf, int len)
- {
- unsigned long s1 = adler & 0xffff;
- unsigned long s2 = (adler >> 16) & 0xffff;
- int n;
-
- for (n = 0; n < len; n++) {
- s1 = (s1 + buf[n]) % BASE;
- s2 = (s2 + s1) % BASE;
- }
- return (s2 << 16) + s1;
- }
-
- /* Return the adler32 of the bytes buf[0..len-1] */

-1. Introduction
-
- 1.1. Purpose
-
- The purpose of this specification is to define a lossless
- compressed data format that:
- * Is independent of CPU type, operating system, file system,
- and character set, and hence can be used for interchange;
- * Can be produced or consumed, even for an arbitrarily long
- sequentially presented input data stream, using only an a
- priori bounded amount of intermediate storage, and hence
- can be used in data communications or similar structures
- such as Unix filters;
- * Compresses data with efficiency comparable to the best
- currently available general-purpose compression methods,
- and in particular considerably better than the "compress"
- program;
- * Can be implemented readily in a manner not covered by
- patents, and hence can be practiced freely;
-
-
-
-Deutsch Informational [Page 2]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- * Is compatible with the file format produced by the current
- widely used gzip utility, in that conforming decompressors
- will be able to read data produced by the existing gzip
- compressor.
-
- The data format defined by this specification does not attempt to:
-
- * Allow random access to compressed data;
- * Compress specialized data (e.g., raster graphics) as well
- as the best currently available specialized algorithms.
-
- A simple counting argument shows that no lossless compression
- algorithm can compress every possible input data set. For the
- format defined here, the worst case expansion is 5 bytes per 32K-
- byte block, i.e., a size increase of 0.015% for large data sets.
- English text usually compresses by a factor of 2.5 to 3;
- executable files usually compress somewhat less; graphical data
- such as raster images may compress much more.
-
- 1.2. Intended audience
-
- This specification is intended for use by implementors of software
- to compress data into "deflate" format and/or decompress data from
- "deflate" format.
-
- The text of the specification assumes a basic background in
- programming at the level of bits and other primitive data
- representations. Familiarity with the technique of Huffman coding
- is helpful but not required.
-
- 1.3. Scope
-
- The specification specifies a method for representing a sequence
- of bytes as a (usually shorter) sequence of bits, and a method for
- packing the latter bit sequence into bytes.
-
- 1.4. Compliance
-
- Unless otherwise indicated below, a compliant decompressor must be
- able to accept and decompress any data set that conforms to all
- the specifications presented here; a compliant compressor must
- produce data sets that conform to all the specifications presented
- here.
-
- 1.5. Definitions of terms and conventions used
-
- Byte: 8 bits stored or transmitted as a unit (same as an octet).
- For this specification, a byte is exactly 8 bits, even on machines
-
-
-
-Deutsch Informational [Page 3]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- which store a character on a number of bits different from eight.
- See below, for the numbering of bits within a byte.
-
- String: a sequence of arbitrary bytes.
-
- 1.6. Changes from previous versions
-
- There have been no technical changes to the deflate format since
- version 1.1 of this specification. In version 1.2, some
- terminology was changed. Version 1.3 is a conversion of the
- specification to RFC style.
-
-2. Compressed representation overview
-
- A compressed data set consists of a series of blocks, corresponding
- to successive blocks of input data. The block sizes are arbitrary,
- except that non-compressible blocks are limited to 65,535 bytes.
-
- Each block is compressed using a combination of the LZ77 algorithm
- and Huffman coding. The Huffman trees for each block are independent
- of those for previous or subsequent blocks; the LZ77 algorithm may
- use a reference to a duplicated string occurring in a previous block,
- up to 32K input bytes before.
-
- Each block consists of two parts: a pair of Huffman code trees that
- describe the representation of the compressed data part, and a
- compressed data part. (The Huffman trees themselves are compressed
- using Huffman encoding.) The compressed data consists of a series of
- elements of two types: literal bytes (of strings that have not been
- detected as duplicated within the previous 32K input bytes), and
- pointers to duplicated strings, where a pointer is represented as a
- pair <length, backward distance>. The representation used in the
- "deflate" format limits distances to 32K bytes and lengths to 258
- bytes, but does not limit the size of a block, except for
- uncompressible blocks, which are limited as noted above.
-
- Each type of value (literals, distances, and lengths) in the
- compressed data is represented using a Huffman code, using one code
- tree for literals and lengths and a separate code tree for distances.
- The code trees for each block appear in a compact form just before
- the compressed data for that block.

-3. Detailed specification
-
- 3.1. Overall conventions In the diagrams below, a box like this:
-
- +---+
- | | <-- the vertical bars might be missing
- +---+
-
- represents one byte; a box like this:
-
- +==============+
- | |
- +==============+
-
- represents a variable number of bytes.
-
- Bytes stored within a computer do not have a "bit order", since
- they are always treated as a unit. However, a byte considered as
- an integer between 0 and 255 does have a most- and least-
- significant bit, and since we write numbers with the most-
- significant digit on the left, we also write bytes with the most-
- significant bit on the left. In the diagrams below, we number the
- bits of a byte so that bit 0 is the least-significant bit, i.e.,
- the bits are numbered:
-
- +--------+
- |76543210|
- +--------+
-
- Within a computer, a number may occupy multiple bytes. All
- multi-byte numbers in the format described here are stored with
- the least-significant byte first (at the lower memory address).
- For example, the decimal number 520 is stored as:
-
- 0 1
- +--------+--------+
- |00001000|00000010|
- +--------+--------+
- ^ ^
- | |
- | + more significant byte = 2 x 256
- + less significant byte = 8
-
- 3.1.1. Packing into bytes
-
- This document does not address the issue of the order in which
- bits of a byte are transmitted on a bit-sequential medium,
- since the final data format described here is byte- rather than
-
-
-
-Deutsch Informational [Page 5]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- bit-oriented. However, we describe the compressed block format
- in below, as a sequence of data elements of various bit
- lengths, not a sequence of bytes. We must therefore specify
- how to pack these data elements into bytes to form the final
- compressed byte sequence:
-
- * Data elements are packed into bytes in order of
- increasing bit number within the byte, i.e., starting
- with the least-significant bit of the byte.
- * Data elements other than Huffman codes are packed
- starting with the least-significant bit of the data
- element.
- * Huffman codes are packed starting with the most-
- significant bit of the code.
-
- In other words, if one were to print out the compressed data as
- a sequence of bytes, starting with the first byte at the
- *right* margin and proceeding to the *left*, with the most-
- significant bit of each byte on the left as usual, one would be
- able to parse the result from right to left, with fixed-width
- elements in the correct MSB-to-LSB order and Huffman codes in
- bit-reversed order (i.e., with the first bit of the code in the
- relative LSB position).
-
- 3.2. Compressed block format
-
- 3.2.1. Synopsis of prefix and Huffman coding
-
- Prefix coding represents symbols from an a priori known
- alphabet by bit sequences (codes), one code for each symbol, in
- a manner such that different symbols may be represented by bit
- sequences of different lengths, but a parser can always parse
- an encoded string unambiguously symbol-by-symbol.
-
- We define a prefix code in terms of a binary tree in which the
- two edges descending from each non-leaf node are labeled 0 and
- 1 and in which the leaf nodes correspond one-for-one with (are
- labeled with) the symbols of the alphabet; then the code for a
- symbol is the sequence of 0's and 1's on the edges leading from
- the root to the leaf labeled with that symbol. For example:
-

-
-
- /\ Symbol Code
- 0 1 ------ ----
- / \ A 00
- /\ B B 1
- 0 1 C 011
- / \ D 010
- A /\
- 0 1
- / \
- D C
-
- A parser can decode the next symbol from an encoded input
- stream by walking down the tree from the root, at each step
- choosing the edge corresponding to the next input bit.
-
- Given an alphabet with known symbol frequencies, the Huffman
- algorithm allows the construction of an optimal prefix code
- (one which represents strings with those symbol frequencies
- using the fewest bits of any possible prefix codes for that
- alphabet). Such a code is called a Huffman code. (See
- reference [1] in Chapter 5, references for additional
- information on Huffman codes.)
-
- Note that in the "deflate" format, the Huffman codes for the
- various alphabets must not exceed certain maximum code lengths.
- This constraint complicates the algorithm for computing code
- lengths from symbol frequencies. Again, see Chapter 5,
- references for details.
-
- 3.2.2. Use of Huffman coding in the "deflate" format
-
- The Huffman codes used for each alphabet in the "deflate"
- format have two additional rules:
-
- * All codes of a given bit length have lexicographically
- consecutive values, in the same order as the symbols
- they represent;
-
- * Shorter codes lexicographically precede longer codes.
-
-
-
-
-
-
-
-
-
-
-
-
-Deutsch Informational [Page 7]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- We could recode the example above to follow this rule as
- follows, assuming that the order of the alphabet is ABCD:
-
- Symbol Code
- ------ ----
- A 10
- B 0
- C 110
- D 111
-
- I.e., 0 precedes 10 which precedes 11x, and 110 and 111 are
- lexicographically consecutive.
-
- Given this rule, we can define the Huffman code for an alphabet
- just by giving the bit lengths of the codes for each symbol of
- the alphabet in order; this is sufficient to determine the
- actual codes. In our example, the code is completely defined
- by the sequence of bit lengths (2, 1, 3, 3). The following
- algorithm generates the codes as integers, intended to be read
- from most- to least-significant bit. The code lengths are
- initially in tree[I].Len; the codes are produced in
- tree[I].Code.
-
- 1) Count the number of codes for each code length. Let
- bl_count[N] be the number of codes of length N, N >= 1.
-
- 2) Find the numerical value of the smallest code for each
- code length:
-
- code = 0;
- bl_count[0] = 0;
- for (bits = 1; bits <= MAX_BITS; bits++) {
- code = (code + bl_count[bits-1]) << 1;
- next_code[bits] = code;
- }
-
- 3) Assign numerical values to all codes, using consecutive

- values determined at step 2. Codes that are never used
- (which have a bit length of zero) must not be assigned a
- value.

- 2 1

-
- Step 2 computes the following next_code values:
-
- N next_code[N]

- G 4 1110
- H 4 1111
-
- 3.2.3. Details of block format
-
- Each block of compressed data begins with 3 header bits
- containing the following data:
-
- first bit BFINAL
- next 2 bits BTYPE
-
- Note that the header bits do not necessarily begin on a byte
- boundary, since a block does not necessarily occupy an integral
- number of bytes.
-
-
-
-
-
-Deutsch Informational [Page 9]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- BFINAL is set if and only if this is the last block of the data
- set.
-
- BTYPE specifies how the data are compressed, as follows:
-
- 00 - no compression
- 01 - compressed with fixed Huffman codes
- 10 - compressed with dynamic Huffman codes
- 11 - reserved (error)
-
- The only difference between the two compressed cases is how the
- Huffman codes for the literal/length and distance alphabets are
- defined.
-
- In all cases, the decoding algorithm for the actual data is as
- follows:
-
- do
- read block header from input stream.
- if stored with no compression
- skip any remaining bits in current partially
- processed byte
- read LEN and NLEN (see next section)
- copy LEN bytes of data to output
- otherwise
- if compressed with dynamic Huffman codes
- read representation of code trees (see
- subsection below)
- loop (until end of block code recognized)
- decode literal/length value from input stream
- if value < 256
- copy value (literal byte) to output stream
- otherwise
- if value = end of block (256)
- break from loop
- otherwise (value = 257..285)
- decode distance from input stream
-
- move backwards distance bytes in the output
- stream, and copy length bytes from this
- position to the output stream.
- end loop
- while not last block
-
- Note that a duplicated string reference may refer to a string
- in a previous block; i.e., the backward distance may cross one
- or more block boundaries. However a distance cannot refer past
- the beginning of the output stream. (An application using a
-
-
-
-Deutsch Informational [Page 10]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- preset dictionary might discard part of the output stream; a
- distance can refer to that part of the output stream anyway)
- Note also that the referenced string may overlap the current
- position; for example, if the last 2 bytes decoded have values
- X and Y, a string reference with <length = 5, distance = 2>
- adds X,Y,X,Y,X to the output stream.
-
- We now specify each compression method in turn.
-
- 3.2.4. Non-compressed blocks (BTYPE=00)
-
- Any bits of input up to the next byte boundary are ignored.
- The rest of the block consists of the following information:
-
- 0 1 2 3 4...
- +---+---+---+---+================================+
- | LEN | NLEN |... LEN bytes of literal data...|
- +---+---+---+---+================================+
-
- LEN is the number of data bytes in the block. NLEN is the
- one's complement of LEN.
-
- 3.2.5. Compressed blocks (length and distance codes)
-
- As noted above, encoded data blocks in the "deflate" format
- consist of sequences of symbols drawn from three conceptually
- distinct alphabets: either literal bytes, from the alphabet of
- byte values (0..255), or <length, backward distance> pairs,
- where the length is drawn from (3..258) and the distance is
- drawn from (1..32,768). In fact, the literal and length
- alphabets are merged into a single alphabet (0..285), where
- values 0..255 represent literal bytes, the value 256 indicates
- end-of-block, and values 257..285 represent length codes
- (possibly in conjunction with extra bits following the symbol
- code) as follows:

-
- 3.2.6. Compression with fixed Huffman codes (BTYPE=01)
-
- The Huffman codes for the two alphabets are fixed, and are not
- represented explicitly in the data. The Huffman code lengths
- for the literal/length alphabet are:
-
- Lit Value Bits Codes
- --------- ---- -----
- 0 - 143 8 00110000 through
- 10111111
- 144 - 255 9 110010000 through
- 111111111
- 256 - 279 7 0000000 through
- 0010111
- 280 - 287 8 11000000 through
- 11000111
-
-
-
-Deutsch Informational [Page 12]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- The code lengths are sufficient to generate the actual codes,
- as described above; we show the codes in the table for added
- clarity. Literal/length values 286-287 will never actually
- occur in the compressed data, but participate in the code
- construction.
-
- Distance codes 0-31 are represented by (fixed-length) 5-bit
- codes, with possible additional bits as shown in the table
- shown in Paragraph 3.2.5, above. Note that distance codes 30-
- 31 will never actually occur in the compressed data.
-
- 3.2.7. Compression with dynamic Huffman codes (BTYPE=10)
-
- The Huffman codes for the two alphabets appear in the block
- immediately after the header bits and before the actual
- compressed data, first the literal/length code and then the
- distance code. Each code is defined by a sequence of code
- lengths, as discussed in Paragraph 3.2.2, above. For even
- greater compactness, the code length sequences themselves are
- compressed using a Huffman code. The alphabet for code lengths
- is as follows:
-
- 0 - 15: Represent code lengths of 0 - 15
- 16: Copy the previous code length 3 - 6 times.
- The next 2 bits indicate repeat length
- (0 = 3, ... , 3 = 6)
- Example: Codes 8, 16 (+2 bits 11),
- 16 (+2 bits 10) will expand to
- 12 code lengths of 8 (1 + 6 + 5)
- 17: Repeat a code length of 0 for 3 - 10 times.
- (3 bits of length)
- 18: Repeat a code length of 0 for 11 - 138 times
- (7 bits of length)
-
- A code length of 0 indicates that the corresponding symbol in
- the literal/length or distance alphabet will not occur in the
- block, and should not participate in the Huffman code
- construction algorithm given earlier. If only one distance
- code is used, it is encoded using one bit, not zero bits; in
- this case there is a single code length of one, with one unused
- code. One distance code of zero bits means that there are no
- distance codes used at all (the data is all literals).
-
- We can now define the format of the block:
-
- 5 Bits: HLIT, # of Literal/Length codes - 257 (257 - 286)
- 5 Bits: HDIST, # of Distance codes - 1 (1 - 32)
- 4 Bits: HCLEN, # of Code Length codes - 4 (4 - 19)
-
-
-
-Deutsch Informational [Page 13]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- (HCLEN + 4) x 3 bits: code lengths for the code length
- alphabet given just above, in the order: 16, 17, 18,
- 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15
-
- These code lengths are interpreted as 3-bit integers
- (0-7); as above, a code length of 0 means the
- corresponding symbol (literal/length or distance code
- length) is not used.
-
- HLIT + 257 code lengths for the literal/length alphabet,
- encoded using the code length Huffman code
-
- HDIST + 1 code lengths for the distance alphabet,
- encoded using the code length Huffman code
-
- The actual compressed data of the block,
- encoded using the literal/length and distance Huffman
- codes
-
- The literal/length symbol 256 (end of data),
- encoded using the literal/length Huffman code
-
- The code length repeat codes can cross from HLIT + 257 to the
- HDIST + 1 code lengths. In other words, all code lengths form
- a single sequence of HLIT + HDIST + 258 values.
-
- 3.3. Compliance
-
- A compressor may limit further the ranges of values specified in
- the previous section and still be compliant; for example, it may
- limit the range of backward pointers to some value smaller than
- 32K. Similarly, a compressor may limit the size of blocks so that
- a compressible block fits in memory.
-
- A compliant decompressor must accept the full range of possible
- values defined in the previous section, and must accept blocks of
- arbitrary size.
-
-4. Compression algorithm details
-
- While it is the intent of this document to define the "deflate"
- compressed data format without reference to any particular
- compression algorithm, the format is related to the compressed
- formats produced by LZ77 (Lempel-Ziv 1977, see reference [2] below);
- since many variations of LZ77 are patented, it is strongly
- recommended that the implementor of a compressor follow the general
- algorithm presented here, which is known not to be patented per se.
- The material in this section is not part of the definition of the
-
-
-
-Deutsch Informational [Page 14]
-
-RFC 1951 DEFLATE Compressed Data Format Specification May 1996
-
-
- specification per se, and a compressor need not follow it in order to
- be compliant.
-
- The compressor terminates a block when it determines that starting a
- new block with fresh trees would be useful, or when the block size
- fills up the compressor's block buffer.
-
- The compressor uses a chained hash table to find duplicated strings,
- using a hash function that operates on 3-byte sequences. At any
- given point during compression, let XYZ be the next 3 input bytes to
- be examined (not necessarily all different, of course). First, the
- compressor examines the hash chain for XYZ. If the chain is empty,
- the compressor simply writes out X as a literal byte and advances one
- byte in the input. If the hash chain is not empty, indicating that
- the sequence XYZ (or, if we are unlucky, some other 3 bytes with the
- same hash function value) has occurred recently, the compressor
- compares all strings on the XYZ hash chain with the actual input data
- sequence starting at the current point, and selects the longest
- match.
-
- The compressor searches the hash chains starting with the most recent
- strings, to favor small distances and thus take advantage of the
- Huffman encoding. The hash chains are singly linked. There are no
- deletions from the hash chains; the algorithm simply discards matches
- that are too old. To avoid a worst-case situation, very long hash
- chains are arbitrarily truncated at a certain length, determined by a
- run-time parameter.
-
- To improve overall compression, the compressor optionally defers the
- selection of matches ("lazy matching"): after a match of length N has
- been found, the compressor searches for a longer match starting at
- the next input byte. If it finds a longer match, it truncates the
- previous match to a length of one (thus producing a single literal
- byte) and then emits the longer match. Otherwise, it emits the
- original match, and, as described above, advances N bytes before
- continuing.
-
- Run-time parameters also control this "lazy match" procedure. If
- compression ratio is most important, the compressor attempts a
- complete second search regardless of the length of the first match.
- In the normal case, if the current match is "long enough", the
- compressor reduces the search for a longer match, thus speeding up
- the process. If speed is most important, the compressor inserts new
- strings in the hash table only when no match was found, or when the
- match is not "too long". This degrades the compression ratio but
- saves time since there are both fewer insertions and fewer searches.

- This specification defines a lossless compressed data format that is
- compatible with the widely used GZIP utility. The format includes a
- cyclic redundancy check value for detecting data corruption. The
- format presently uses the DEFLATE method of compression but can be
- easily extended to use other compression methods. The format can be
- implemented readily in a manner not covered by patents.

-1. Introduction
-
- 1.1. Purpose
-
- The purpose of this specification is to define a lossless
- compressed data format that:
-
- * Is independent of CPU type, operating system, file system,
- and character set, and hence can be used for interchange;
- * Can compress or decompress a data stream (as opposed to a
- randomly accessible file) to produce another data stream,
- using only an a priori bounded amount of intermediate
- storage, and hence can be used in data communications or
- similar structures such as Unix filters;
- * Compresses data with efficiency comparable to the best
- currently available general-purpose compression methods,
- and in particular considerably better than the "compress"
- program;
- * Can be implemented readily in a manner not covered by
- patents, and hence can be practiced freely;
- * Is compatible with the file format produced by the current
- widely used gzip utility, in that conforming decompressors
- will be able to read data produced by the existing gzip
- compressor.
-
-
-
-
-Deutsch Informational [Page 2]
-
-RFC 1952 GZIP File Format Specification May 1996
-
-
- The data format defined by this specification does not attempt to:
-
- * Provide random access to compressed data;
- * Compress specialized data (e.g., raster graphics) as well as
- the best currently available specialized algorithms.
-
- 1.2. Intended audience
-
- This specification is intended for use by implementors of software
- to compress data into gzip format and/or decompress data from gzip
- format.
-
- The text of the specification assumes a basic background in
- programming at the level of bits and other primitive data
- representations.
-
- 1.3. Scope
-
- The specification specifies a compression method and a file format
- (the latter assuming only that a file can store a sequence of
- arbitrary bytes). It does not specify any particular interface to
- a file system or anything about character sets or encodings
- (except for file names and comments, which are optional).
-
- 1.4. Compliance
-
- Unless otherwise indicated below, a compliant decompressor must be
- able to accept and decompress any file that conforms to all the
- specifications presented here; a compliant compressor must produce
- files that conform to all the specifications presented here. The
- material in the appendices is not part of the specification per se
- and is not relevant to compliance.
-
- 1.5. Definitions of terms and conventions used
-
- byte: 8 bits stored or transmitted as a unit (same as an octet).
- (For this specification, a byte is exactly 8 bits, even on
- machines which store a character on a number of bits different
- from 8.) See below for the numbering of bits within a byte.
-
- 1.6. Changes from previous versions
-
- There have been no technical changes to the gzip format since
- version 4.1 of this specification. In version 4.2, some
- terminology was changed, and the sample CRC code was rewritten for
- clarity and to eliminate the requirement for the caller to do pre-
- and post-conditioning. Version 4.3 is a conversion of the
- specification to RFC style.

-2. Detailed specification
-
- 2.1. Overall conventions
-
- In the diagrams below, a box like this:
-
- +---+
- | | <-- the vertical bars might be missing
- +---+
-
- represents one byte; a box like this:
-
- +==============+
- | |
- +==============+
-
- represents a variable number of bytes.
-
- Bytes stored within a computer do not have a "bit order", since
- they are always treated as a unit. However, a byte considered as
- an integer between 0 and 255 does have a most- and least-
- significant bit, and since we write numbers with the most-
- significant digit on the left, we also write bytes with the most-
- significant bit on the left. In the diagrams below, we number the
- bits of a byte so that bit 0 is the least-significant bit, i.e.,
- the bits are numbered:
-
- +--------+
- |76543210|
- +--------+
-
- This document does not address the issue of the order in which
- bits of a byte are transmitted on a bit-sequential medium, since
- the data format described here is byte- rather than bit-oriented.
-
- Within a computer, a number may occupy multiple bytes. All
- multi-byte numbers in the format described here are stored with
- the least-significant byte first (at the lower memory address).
- For example, the decimal number 520 is stored as:
-
- 0 1

-
- 2.2. File format
-
- A gzip file consists of a series of "members" (compressed data
- sets). The format of each member is specified in the following
- section. The members simply appear one after another in the file,
- with no additional information before, between, or after them.
-
- 2.3. Member format
-
- Each member has the following structure:
-
- +---+---+---+---+---+---+---+---+---+---+
- |ID1|ID2|CM |FLG| MTIME |XFL|OS | (more-->)
- +---+---+---+---+---+---+---+---+---+---+
-
- (if FLG.FEXTRA set)
-
- +---+---+=================================+
- | XLEN |...XLEN bytes of "extra field"...| (more-->)
- +---+---+=================================+
-
- (if FLG.FNAME set)
-
- +=========================================+
- |...original file name, zero-terminated...| (more-->)
- +=========================================+
-
- (if FLG.FCOMMENT set)
-
- +===================================+
- |...file comment, zero-terminated...| (more-->)
- +===================================+
-
- (if FLG.FHCRC set)

-
-
- 2.3.1. Member header and trailer
-
- ID1 (IDentification 1)
- ID2 (IDentification 2)
- These have the fixed values ID1 = 31 (0x1f, \037), ID2 = 139
- (0x8b, \213), to identify the file as being in gzip format.
-
- CM (Compression Method)
- This identifies the compression method used in the file. CM
- = 0-7 are reserved. CM = 8 denotes the "deflate"
- compression method, which is the one customarily used by
- gzip and which is documented elsewhere.
-
- FLG (FLaGs)
- This flag byte is divided into individual bits as follows:
-
- bit 0 FTEXT
- bit 1 FHCRC
- bit 2 FEXTRA
- bit 3 FNAME
- bit 4 FCOMMENT
- bit 5 reserved
- bit 6 reserved
- bit 7 reserved
-
- If FTEXT is set, the file is probably ASCII text. This is
- an optional indication, which the compressor may set by
- checking a small amount of the input data to see whether any
- non-ASCII characters are present. In case of doubt, FTEXT
- is cleared, indicating binary data. For systems which have
- different file formats for ascii text and binary data, the
- decompressor can use FTEXT to choose the appropriate format.
- We deliberately do not specify the algorithm used to set
- this bit, since a compressor always has the option of
- leaving it cleared and a decompressor always has the option
- of ignoring it and letting some other program handle issues
- of data conversion.
-
- If FHCRC is set, a CRC16 for the gzip header is present,
- immediately before the compressed data. The CRC16 consists
- of the two least significant bytes of the CRC32 for all
- bytes of the gzip header up to and not including the CRC16.
- [The FHCRC bit was never set by versions of gzip up to
- 1.2.4, even though it was documented with a different
- meaning in gzip 1.2.4.]
-
- If FEXTRA is set, optional extra fields are present, as
- described in a following section.
-
-
-
-Deutsch Informational [Page 6]
-
-RFC 1952 GZIP File Format Specification May 1996
-
-
- If FNAME is set, an original file name is present,
- terminated by a zero byte. The name must consist of ISO
- 8859-1 (LATIN-1) characters; on operating systems using
- EBCDIC or any other character set for file names, the name
- must be translated to the ISO LATIN-1 character set. This
- is the original name of the file being compressed, with any
- directory components removed, and, if the file being
- compressed is on a file system with case insensitive names,
- forced to lower case. There is no original file name if the
- data was compressed from a source other than a named file;
- for example, if the source was stdin on a Unix system, there
- is no file name.
-
- If FCOMMENT is set, a zero-terminated file comment is
- present. This comment is not interpreted; it is only
- intended for human consumption. The comment must consist of
- ISO 8859-1 (LATIN-1) characters. Line breaks should be
- denoted by a single line feed character (10 decimal).
-
- Reserved FLG bits must be zero.
-
- MTIME (Modification TIME)
- This gives the most recent modification time of the original
- file being compressed. The time is in Unix format, i.e.,
- seconds since 00:00:00 GMT, Jan. 1, 1970. (Note that this
- may cause problems for MS-DOS and other systems that use
- local rather than Universal time.) If the compressed data
- did not come from a file, MTIME is set to the time at which
- compression started. MTIME = 0 means no time stamp is
- available.
-
- XFL (eXtra FLags)
- These flags are available for use by specific compression
- methods. The "deflate" method (CM = 8) sets these flags as
- follows:
-
- XFL = 2 - compressor used maximum compression,
- slowest algorithm
- XFL = 4 - compressor used fastest algorithm
-
- OS (Operating System)
- This identifies the type of file system on which compression
- took place. This may be useful in determining end-of-line
- convention for text files. The currently defined values are
- as follows:
-

-
- ISIZE (Input SIZE)
- This contains the size of the original (uncompressed) input
- data modulo 2^32.
-
- 2.3.1.1. Extra field
-
- If the FLG.FEXTRA bit is set, an "extra field" is present in
- the header, with total length XLEN bytes. It consists of a
- series of subfields, each of the form:
-
- +---+---+---+---+==================================+
- |SI1|SI2| LEN |... LEN bytes of subfield data ...|
- +---+---+---+---+==================================+
-
- SI1 and SI2 provide a subfield ID, typically two ASCII letters
- with some mnemonic value. Jean-Loup Gailly
- <gzip@prep.ai.mit.edu> is maintaining a registry of subfield
- IDs; please send him any subfield ID you wish to use. Subfield
- IDs with SI2 = 0 are reserved for future use. The following
- IDs are currently defined:

- 0x41 ('A') 0x70 ('P') Apollo file type information
-
- LEN gives the length of the subfield data, excluding the 4
- initial bytes.
-
- 2.3.1.2. Compliance
-
- A compliant compressor must produce files with correct ID1,
- ID2, CM, CRC32, and ISIZE, but may set all the other fields in
- the fixed-length part of the header to default values (255 for
- OS, 0 for all others). The compressor must set all reserved
- bits to zero.
-
- A compliant decompressor must check ID1, ID2, and CM, and
- provide an error indication if any of these have incorrect
- values. It must examine FEXTRA/XLEN, FNAME, FCOMMENT and FHCRC
- at least so it can skip over the optional fields if they are
- present. It need not examine any other part of the header or
- trailer; in particular, a decompressor may ignore FTEXT and OS
- and always produce binary output, and still be compliant. A
- compliant decompressor must give an error indication if any
- reserved bit is non-zero, since such a bit could indicate the
- presence of a new field that would cause subsequent data to be
- interpreted incorrectly.

- the specification per se, and implementations need not follow it to
- be compliant.
-
- When compressing or decompressing a file, gzip preserves the
- protection, ownership, and modification time attributes on the local
- file system, since there is no provision for representing protection
- attributes in the gzip file format itself. Since the file format
- includes a modification time, the gzip decompressor provides a
- command line switch that assigns the modification time from the file,
- rather than the local modification time of the compressed input, to
- the decompressed output.
-

- The following sample code represents a practical implementation of
- the CRC (Cyclic Redundancy Check). (See also ISO 3309 and ITU-T V.42
- for a formal specification.)
-
- The sample code is in the ANSI C programming language. Non C users
- may find it easier to read with these hints:
-
- & Bitwise AND operator.
- ^ Bitwise exclusive-OR operator.
- >> Bitwise right shift operator. When applied to an
- unsigned quantity, as here, right shift inserts zero
- bit(s) at the left.
- ! Logical NOT operator.
- ++ "n++" increments the variable n.

-A Fast Method for Identifying Plain Text Files
-==============================================
-
-
-Introduction
-------------
-
-Given a file coming from an unknown source, it is sometimes desirable
-to find out whether the format of that file is plain text. Although
-this may appear like a simple task, a fully accurate detection of the
-file type requires heavy-duty semantic analysis on the file contents.
-It is, however, possible to obtain satisfactory results by employing
-various heuristics.
-
-Previous versions of PKZip and other zip-compatible compression tools
-were using a crude detection scheme: if more than 80% (4/5) of the bytes
-found in a certain buffer are within the range [7..127], the file is
-labeled as plain text, otherwise it is labeled as binary. A prominent
-limitation of this scheme is the restriction to Latin-based alphabets.
-Other alphabets, like Greek, Cyrillic or Asian, make extensive use of
-the bytes within the range [128..255], and texts using these alphabets
-are most often misidentified by this scheme; in other words, the rate
-of false negatives is sometimes too high, which means that the recall
-is low. Another weakness of this scheme is a reduced precision, due to
-the false positives that may occur when binary files containing large
-amounts of textual characters are misidentified as plain text.
-
-In this article we propose a new, simple detection scheme that features
-a much increased precision and a near-100% recall. This scheme is
-designed to work on ASCII, Unicode and other ASCII-derived alphabets,
-and it handles single-byte encodings (ISO-8859, MacRoman, KOI8, etc.)
-and variable-sized encodings (ISO-2022, UTF-8, etc.). Wider encodings
-(UCS-2/UTF-16 and UCS-4/UTF-32) are not handled, however.
-
-
-The Algorithm
--------------
-
-The algorithm works by dividing the set of bytecodes [0..255] into three
-categories:
-- The white list of textual bytecodes:
- 9 (TAB), 10 (LF), 13 (CR), 32 (SPACE) to 255.
-- The gray list of tolerated bytecodes:
- 7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB), 27 (ESC).
-- The black list of undesired, non-textual bytecodes:
- 0 (NUL) to 6, 14 to 31.
-
-If a file contains at least one byte that belongs to the white list and
-no byte that belongs to the black list, then the file is categorized as
-plain text; otherwise, it is categorized as binary. (The boundary case,
-when the file is empty, automatically falls into the latter category.)
-
-
-Rationale
----------
-
-The idea behind this algorithm relies on two observations.
-
-The first observation is that, although the full range of 7-bit codes
-[0..127] is properly specified by the ASCII standard, most control
-characters in the range [0..31] are not used in practice. The only
-widely-used, almost universally-portable control codes are 9 (TAB),
-10 (LF) and 13 (CR). There are a few more control codes that are
-recognized on a reduced range of platforms and text viewers/editors:
-7 (BEL), 8 (BS), 11 (VT), 12 (FF), 26 (SUB) and 27 (ESC); but these
-codes are rarely (if ever) used alone, without being accompanied by
-some printable text. Even the newer, portable text formats such as
-XML avoid using control characters outside the list mentioned here.
-
-The second observation is that most of the binary files tend to contain
-control characters, especially 0 (NUL). Even though the older text
-detection schemes observe the presence of non-ASCII codes from the range
-[128..255], the precision rarely has to suffer if this upper range is
-labeled as textual, because the files that are genuinely binary tend to
-contain both control characters and codes from the upper range. On the
-other hand, the upper range needs to be labeled as textual, because it
-is used by virtually all ASCII extensions. In particular, this range is
-used for encoding non-Latin scripts.
-
-Since there is no counting involved, other than simply observing the
-presence or the absence of some byte values, the algorithm produces
-consistent results, regardless what alphabet encoding is being used.
-(If counting were involved, it could be possible to obtain different
-results on a text encoded, say, using ISO-8859-16 versus UTF-8.)
-
-There is an extra category of plain text files that are "polluted" with
-one or more black-listed codes, either by mistake or by peculiar design
-considerations. In such cases, a scheme that tolerates a small fraction
-of black-listed codes would provide an increased recall (i.e. more true
-positives). This, however, incurs a reduced precision overall, since
-false positives are more likely to appear in binary files that contain
-large chunks of textual data. Furthermore, "polluted" plain text should
-be regarded as binary by general-purpose text detection schemes, because
-general-purpose text processing algorithms might not be applicable.
-Under this premise, it is safe to say that our detection method provides
-a near-100% recall.
-
-Experiments have been run on many files coming from various platforms
-and applications. We tried plain text files, system logs, source code,
-formatted office documents, compiled object code, etc. The results
-confirm the optimistic assumptions about the capabilities of this
-algorithm.

-/*
- Examine all possible Huffman codes for a given number of symbols and a
- maximum code length in bits to determine the maximum table size for zilb's
- inflate. Only complete Huffman codes are counted.
-
- Two codes are considered distinct if the vectors of the number of codes per
- length are not identical. So permutations of the symbol assignments result
- in the same code for the counting, as do permutations of the assignments of
- the bit values to the codes (i.e. only canonical codes are counted).
-
- We build a code from shorter to longer lengths, determining how many symbols
- are coded at each length. At each step, we have how many symbols remain to
- be coded, what the last code length used was, and how many bit patterns of
- that length remain unused. Then we add one to the code length and double the
- number of unused patterns to graduate to the next code length. We then
- assign all portions of the remaining symbols to that code length that
- preserve the properties of a correct and eventually complete code. Those
- properties are: we cannot use more bit patterns than are available; and when
- all the symbols are used, there are exactly zero possible bit patterns
- remaining.
-
- The inflate Huffman decoding algorithm uses two-level lookup tables for
- speed. There is a single first-level table to decode codes up to root bits
- in length (root == 9 in the current inflate implementation). The table
- has 1 << root entries and is indexed by the next root bits of input. Codes
- shorter than root bits have replicated table entries, so that the correct
- entry is pointed to regardless of the bits that follow the short code. If
- the code is longer than root bits, then the table entry points to a second-
- level table. The size of that table is determined by the longest code with
- that root-bit prefix. If that longest code has length len, then the table
- has size 1 << (len - root), to index the remaining bits in that set of
- codes. Each subsequent root-bit prefix then has its own sub-table. The
- total number of table entries required by the code is calculated
- incrementally as the number of codes at each bit length is populated. When
- all of the codes are shorter than root bits, then root is reduced to the
- longest code length, resulting in a single, smaller, one-level table.
-
- The inflate algorithm also provides for small values of root (relative to
- the log2 of the number of symbols), where the shortest code has more bits
- than root. In that case, root is increased to the length of the shortest
- code. This program, by design, does not handle that case, so it is verified
- that the number of symbols is less than 2^(root + 1).
-
- In order to speed up the examination (by about ten orders of magnitude for
- the default arguments), the intermediate states in the build-up of a code
- are remembered and previously visited branches are pruned. The memory
- required for this will increase rapidly with the total number of symbols and
- the maximum code length in bits. However this is a very small price to pay
- for the vast speedup.
-
- First, all of the possible Huffman codes are counted, and reachable
- intermediate states are noted by a non-zero count in a saved-results array.
- Second, the intermediate states that lead to (root + 1) bit or longer codes
- are used to look at all sub-codes from those junctures for their inflate
- memory usage. (The amount of memory used is not affected by the number of
- codes of root bits or less in length.) Third, the visited states in the
- construction of those sub-codes and the associated calculation of the table
- size is recalled in order to avoid recalculating from the same juncture.
- Beginning the code examination at (root + 1) bit codes, which is enabled by
- identifying the reachable nodes, accounts for about six of the orders of
- magnitude of improvement for the default arguments. About another four
- orders of magnitude come from not revisiting previous states. Out of
- approximately 2x10^16 possible Huffman codes, only about 2x10^6 sub-codes
- need to be examined to cover all of the possible table memory usage cases
- for the default arguments of 286 symbols limited to 15-bit codes.
-
- Note that an unsigned long long type is used for counting. It is quite easy
- to exceed the capacity of an eight-byte integer with a large number of
- symbols and a large maximum code length, so multiple-precision arithmetic
- would need to replace the unsigned long long arithmetic in that case. This
- program will abort if an overflow occurs. The big_t type identifies where
- the counting takes place.
-
- An unsigned long long type is also used for calculating the number of
- possible codes remaining at the maximum length. This limits the maximum
- code length to the number of bits in a long long minus the number of bits
- needed to represent the symbols in a flat code. The code_t type identifies
- where the bit pattern counting takes place.

-/* The array for saving results, num[], is indexed with this triplet:
-
- syms: number of symbols remaining to code
- left: number of available bit patterns at length len
- len: number of bits in the codes currently being assigned
-
- Those indices are constrained thusly when saving results:
-
- syms: 3..totsym (totsym == total symbols to code)
- left: 2..syms - 1, but only the evens (so syms == 8 -> 2, 4, 6)
- len: 1..max - 1 (max == maximum code length in bits)
-
- syms == 2 is not saved since that immediately leads to a single code. left
- must be even, since it represents the number of available bit patterns at
- the current length, which is double the number at the previous length.
- left ends at syms-1 since left == syms immediately results in a single code.
- (left > sym is not allowed since that would result in an incomplete code.)
- len is less than max, since the code completes immediately when len == max.
-
- The offset into the array is calculated for the three indices with the
- first one (syms) being outermost, and the last one (len) being innermost.
- We build the array with length max-1 lists for the len index, with syms-3
- of those for each symbol. There are totsym-2 of those, with each one
- varying in length as a function of sym. See the calculation of index in
- count() for the index, and the calculation of size in main() for the size
- of the array.
-
- For the deflate example of 286 symbols limited to 15-bit codes, the array
- has 284,284 entries, taking up 2.17 MB for an 8-byte big_t. More than
- half of the space allocated for saved results is actually used -- not all

- states. mem and rem are used to calculate a single index in a triangular
- array. Since the range of mem is expected in the default case to be about
- ten times larger than the range of rem, the array is skewed to reduce the
- memory usage, with eight times the range for mem than for rem. See the
- calculations for offset and bit in beenhere() for the details.

-/* fitblk.c: example of fitting compressed output to a specified size
- Not copyrighted -- provided to the public domain
- Version 1.1 25 November 2004 Mark Adler */

-/* Version history:
- 1.0 24 Nov 2004 First version
- 1.1 25 Nov 2004 Change deflateInit2() to deflateInit()
- Use fixed-size, stack-allocated raw buffers
- Simplify code moving compression to subroutines
- Use assert() for internal errors
- Add detailed description of approach
- */
-
-/* Approach to just fitting a requested compressed size:
-
- fitblk performs three compression passes on a portion of the input
- data in order to determine how much of that input will compress to
- nearly the requested output block size. The first pass generates
- enough deflate blocks to produce output to fill the requested
- output size plus a specfied excess amount (see the EXCESS define
- below). The last deflate block may go quite a bit past that, but
- is discarded. The second pass decompresses and recompresses just
- the compressed data that fit in the requested plus excess sized
- buffer. The deflate process is terminated after that amount of
- input, which is less than the amount consumed on the first pass.
- The last deflate block of the result will be of a comparable size
- to the final product, so that the header for that deflate block and
- the compression ratio for that block will be about the same as in
- the final product. The third compression pass decompresses the
- result of the second step, but only the compressed data up to the
- requested size minus an amount to allow the compressed stream to
- complete (see the MARGIN define below). That will result in a
- final compressed stream whose length is less than or equal to the
- requested size. Assuming sufficient input and a requested size
- greater than a few hundred bytes, the shortfall will typically be
- less than ten bytes.
-
- If the input is short enough that the first compression completes
- before filling the requested output size, then that compressed
- stream is return with no recompression.
-
- EXCESS is chosen to be just greater than the shortfall seen in a
- two pass approach similar to the above. That shortfall is due to
- the last deflate block compressing more efficiently with a smaller
- header on the second pass. EXCESS is set to be large enough so
- that there is enough uncompressed data for the second pass to fill
- out the requested size, and small enough so that the final deflate
- block of the second pass will be close in size to the final deflate
- block of the third and final pass. MARGIN is chosen to be just
- large enough to assure that the final compression has enough room
- to complete in all cases.

- gun [ -t ] [ name ... ]
-
- decompresses the data in the named gzip files. If no arguments are given,
- gun will decompress from stdin to stdout. The names must end in .gz, -gz,
- .z, -z, _z, or .Z. The uncompressed data will be written to a file name
- with the suffix stripped. On success, the original file is deleted. On
- failure, the output file is deleted. For most failures, the command will
- continue to process the remaining names on the command line. A memory
- allocation failure will abort the command. If -t is specified, then the
- listed files or stdin will be tested as gzip files for integrity (without
- checking for a proper suffix), no output will be written, and no files
- will be deleted.
-
- Like gzip, gun allows concatenated gzip streams and will decompress them,
- writing all of the uncompressed data to the output. Unlike gzip, gun allows
- an empty file on input, and will produce no error writing an empty output
- file.
-
- gun will also decompress files made by Unix compress, which uses LZW
- compression. These files are automatically detected by virtue of their
- magic header bytes. Since the end of Unix compress stream is marked by the
- end-of-file, they cannot be concantenated. If a Unix compress stream is
- encountered in an input file, it is the last stream in that file.
-
- Like gunzip and uncompress, the file attributes of the orignal compressed
- file are maintained in the final uncompressed file, to the extent that the
- user permissions allow it.
-
- On my Mac OS X PowerPC G4, gun is almost twice as fast as gunzip (version
- 1.2.4) is on the same file, when gun is linked with zlib 1.2.2. Also the
- LZW decompression provided by gun is about twice as fast as the standard
- Unix uncompress command.

- gzappend takes a gzip file and appends to it, compressing files from the
- command line or data from stdin. The gzip file is written to directly, to
- avoid copying that file, in case it's large. Note that this results in the
- unfriendly behavior that if gzappend fails, the gzip file is corrupted.
-
- This program was written to illustrate the use of the new Z_BLOCK option of
- zlib 1.2.x's inflate() function. This option returns from inflate() at each
- block boundary to facilitate locating and modifying the last block bit at
- the start of the final deflate block. Also whether using Z_BLOCK or not,
- another required feature of zlib 1.2.x is that inflate() now provides the
- number of unusued bits in the last input byte used. gzappend will not work
- with versions of zlib earlier than 1.2.1.
-
- gzappend first decompresses the gzip file internally, discarding all but
- the last 32K of uncompressed data, and noting the location of the last block
- bit and the number of unused bits in the last byte of the compressed data.
- The gzip trailer containing the CRC-32 and length of the uncompressed data
- is verified. This trailer will be later overwritten.
-
- Then the last block bit is cleared by seeking back in the file and rewriting
- the byte that contains it. Seeking forward, the last byte of the compressed
- data is saved along with the number of unused bits to initialize deflate.
-
- A deflate process is initialized, using the last 32K of the uncompressed
- data from the gzip file to initialize the dictionary. If the total
- uncompressed data was less than 32K, then all of it is used to initialize
- the dictionary. The deflate output bit buffer is also initialized with the
- last bits from the original deflate stream. From here on, the data to
- append is simply compressed using deflate, and written to the gzip file.
- When that is complete, the new CRC-32 and uncompressed length are written
- as the trailer of the gzip file.

- gzlog provides a mechanism for frequently appending short strings to a gzip
- file that is efficient both in execution time and compression ratio. The
- strategy is to write the short strings in an uncompressed form to the end of
- the gzip file, only compressing when the amount of uncompressed data has
- reached a given threshold.
-
- gzlog also provides protection against interruptions in the process due to
- system crashes. The status of the operation is recorded in an extra field
- in the gzip file, and is only updated once the gzip file is brought to a
- valid state. The last data to be appended or compressed is saved in an
- auxiliary file, so that if the operation is interrupted, it can be completed
- the next time an append operation is attempted.
-
- gzlog maintains another auxiliary file with the last 32K of data from the
- compressed portion, which is preloaded for the compression of the subsequent
- data. This minimizes the impact to the compression ratio of appending.
- */
-
-/*
- Operations Concept:
-
- Files (log name "foo"):
- foo.gz -- gzip file with the complete log
- foo.add -- last message to append or last data to compress
- foo.dict -- dictionary of the last 32K of data for next compression
- foo.temp -- temporary dictionary file for compression after this one
- foo.lock -- lock file for reading and writing the other files
- foo.repairs -- log file for log file recovery operations (not compressed)
-
- gzip file structure:
- - fixed-length (no file name) header with extra field (see below)
- - compressed data ending initially with empty stored block
- - uncompressed data filling out originally empty stored block and
- subsequent stored blocks as needed (16K max each)
- - gzip trailer
- - no junk at end (no other gzip streams)
-
- When appending data, the information in the first three items above plus the
- foo.add file are sufficient to recover an interrupted append operation. The
- extra field has the necessary information to restore the start of the last
- stored block and determine where to append the data in the foo.add file, as
- well as the crc and length of the gzip data before the append operation.
-
- The foo.add file is created before the gzip file is marked for append, and
- deleted after the gzip file is marked as complete. So if the append
- operation is interrupted, the data to add will still be there. If due to
- some external force, the foo.add file gets deleted between when the append
- operation was interrupted and when recovery is attempted, the gzip file will
- still be restored, but without the appended data.
-
- When compressing data, the information in the first two items above plus the
- foo.add file are sufficient to recover an interrupted compress operation.
- The extra field has the necessary information to find the end of the
- compressed data, and contains both the crc and length of just the compressed
- data and of the complete set of data including the contents of the foo.add
- file.
-
- Again, the foo.add file is maintained during the compress operation in case
- of an interruption. If in the unlikely event the foo.add file with the data
- to be compressed is missing due to some external force, a gzip file with
- just the previous compressed data will be reconstructed. In this case, all
- of the data that was to be compressed is lost (approximately one megabyte).
- This will not occur if all that happened was an interruption of the compress
- operation.
-
- The third state that is marked is the replacement of the old dictionary with
- the new dictionary after a compress operation. Once compression is
- complete, the gzip file is marked as being in the replace state. This
- completes the gzip file, so an interrupt after being so marked does not
- result in recompression. Then the dictionary file is replaced, and the gzip
- file is marked as completed. This state prevents the possibility of
- restarting compression with the wrong dictionary file.
-
- All three operations are wrapped by a lock/unlock procedure. In order to
- gain exclusive access to the log files, first a foo.lock file must be
- exclusively created. When all operations are complete, the lock is
- released by deleting the foo.lock file. If when attempting to create the
- lock file, it already exists and the modify time of the lock file is more
- than five minutes old (set by the PATIENCE define below), then the old
- lock file is considered stale and deleted, and the exclusive creation of
- the lock file is retried. To assure that there are no false assessments
- of the staleness of the lock file, the operations periodically touch the
- lock file to update the modified date.
-
- Following is the definition of the extra field with all of the information
- required to enable the above append and compress operations and their
- recovery if interrupted. Multi-byte values are stored little endian
- (consistent with the gzip format). File pointers are eight bytes long.
- The crc's and lengths for the gzip trailer are four bytes long. (Note that
- the length at the end of a gzip file is used for error checking only, and
- for large files is actually the length modulo 2^32.) The stored block
- length is two bytes long. The gzip extra field two-byte identification is
- "ap" for append. It is assumed that writing the extra field to the file is
- an "atomic" operation. That is, either all of the extra field is written
- to the file, or none of it is, if the operation is interrupted right at the
- point of updating the extra field. This is a reasonable assumption, since
- the extra field is within the first 52 bytes of the file, which is smaller
- than any expected block size for a mass storage device (usually 512 bytes or
- larger).
-
- Extra field (35 bytes):
- - Pointer to first stored block length -- this points to the two-byte length
- of the first stored block, which is followed by the two-byte, one's
- complement of that length. The stored block length is preceded by the
- three-bit header of the stored block, which is the actual start of the
- stored block in the deflate format. See the bit offset field below.
- - Pointer to the last stored block length. This is the same as above, but
- for the last stored block of the uncompressed data in the gzip file.
- Initially this is the same as the first stored block length pointer.
- When the stored block gets to 16K (see the MAX_STORE define), then a new
- stored block as added, at which point the last stored block length pointer
- is different from the first stored block length pointer. When they are
- different, the first bit of the last stored block header is eight bits, or
- one byte back from the block length.
- - Compressed data crc and length. This is the crc and length of the data
- that is in the compressed portion of the deflate stream. These are used
- only in the event that the foo.add file containing the data to compress is
- lost after a compress operation is interrupted.
- - Total data crc and length. This is the crc and length of all of the data
- stored in the gzip file, compressed and uncompressed. It is used to
- reconstruct the gzip trailer when compressing, as well as when recovering
- interrupted operations.
- - Final stored block length. This is used to quickly find where to append,
- and allows the restoration of the original final stored block state when
- an append operation is interrupted.
- - First stored block start as the number of bits back from the final stored
- block first length byte. This value is in the range of 3..10, and is
- stored as the low three bits of the final byte of the extra field after
- subtracting three (0..7). This allows the last-block bit of the stored
- block header to be updated when a new stored block is added, for the case
- when the first stored block and the last stored block are the same. (When
- they are different, the numbers of bits back is known to be eight.) This
- also allows for new compressed data to be appended to the old compressed
- data in the compress operation, overwriting the previous first stored
- block, or for the compressed data to be terminated and a valid gzip file
- reconstructed on the off chance that a compression operation was
- interrupted and the data to compress in the foo.add file was deleted.
- - The operation in process. This is the next two bits in the last byte (the
- bits under the mask 0x18). The are interpreted as 0: nothing in process,
- 1: append in process, 2: compress in process, 3: replace in process.
- - The top three bits of the last byte in the extra field are reserved and
- are currently set to zero.
-
- Main procedure:
- - Exclusively create the foo.lock file using the O_CREAT and O_EXCL modes of
- the system open() call. If the modify time of an existing lock file is
- more than PATIENCE seconds old, then the lock file is deleted and the
- exclusive create is retried.
- - Load the extra field from the foo.gz file, and see if an operation was in
- progress but not completed. If so, apply the recovery procedure below.
- - Perform the append procedure with the provided data.
- - If the uncompressed data in the foo.gz file is 1MB or more, apply the
- compress procedure.
- - Delete the foo.lock file.
-
- Append procedure:
- - Put what to append in the foo.add file so that the operation can be
- restarted if this procedure is interrupted.
- - Mark the foo.gz extra field with the append operation in progress.
- + Restore the original last-block bit and stored block length of the last
- stored block from the information in the extra field, in case a previous
- append operation was interrupted.
- - Append the provided data to the last stored block, creating new stored
- blocks as needed and updating the stored blocks last-block bits and
- lengths.
- - Update the crc and length with the new data, and write the gzip trailer.
- - Write over the extra field (with a single write operation) with the new
- pointers, lengths, and crc's, and mark the gzip file as not in process.
- Though there is still a foo.add file, it will be ignored since nothing
- is in process. If a foo.add file is leftover from a previously
- completed operation, it is truncated when writing new data to it.
- - Delete the foo.add file.
-
- Compress and replace procedures:
- - Read all of the uncompressed data in the stored blocks in foo.gz and write
- it to foo.add. Also write foo.temp with the last 32K of that data to
- provide a dictionary for the next invocation of this procedure.
- - Rewrite the extra field marking foo.gz with a compression in process.
- * If there is no data provided to compress (due to a missing foo.add file
- when recovering), reconstruct and truncate the foo.gz file to contain
- only the previous compressed data and proceed to the step after the next
- one. Otherwise ...
- - Compress the data with the dictionary in foo.dict, and write to the
- foo.gz file starting at the bit immediately following the last previously
- compressed block. If there is no foo.dict, proceed anyway with the
- compression at slightly reduced efficiency. (For the foo.dict file to be
- missing requires some external failure beyond simply the interruption of
- a compress operation.) During this process, the foo.lock file is
- periodically touched to assure that that file is not considered stale by
- another process before we're done. The deflation is terminated with a
- non-last empty static block (10 bits long), that is then located and
- written over by a last-bit-set empty stored block.
- - Append the crc and length of the data in the gzip file (previously
- calculated during the append operations).
- - Write over the extra field with the updated stored block offsets, bits
- back, crc's, and lengths, and mark foo.gz as in process for a replacement
- of the dictionary.
- @ Delete the foo.add file.
- - Replace foo.dict with foo.temp.
- - Write over the extra field, marking foo.gz as complete.
-
- Recovery procedure:
- - If not a replace recovery, read in the foo.add file, and provide that data
- to the appropriate recovery below. If there is no foo.add file, provide
- a zero data length to the recovery. In that case, the append recovery
- restores the foo.gz to the previous compressed + uncompressed data state.
- For the the compress recovery, a missing foo.add file results in foo.gz
- being restored to the previous compressed-only data state.
- - Append recovery:
- - Pick up append at + step above
- - Compress recovery:
- - Pick up compress at * step above
- - Replace recovery:
- - Pick up compress at @ step above
- - Log the repair with a date stamp in foo.repairs

-The first thing we do is to initialize the <em>zlib</em> state for compression using
-<tt>deflateInit()</tt>. This must be done before the first use of <tt>deflate()</tt>.
-The <tt>zalloc</tt>, <tt>zfree</tt>, and <tt>opaque</tt> fields in the <tt>strm</tt>
-structure must be initialized before calling <tt>deflateInit()</tt>. Here they are
-set to the <em>zlib</em> constant <tt>Z_NULL</tt> to request that <em>zlib</em> use
-the default memory allocation routines. An application may also choose to provide
-custom memory allocation routines here. <tt>deflateInit()</tt> will allocate on the
-order of 256K bytes for the internal state.
-(See <a href="zlib_tech.html"><em>zlib Technical Details</em></a>.)
-<p>
-<tt>deflateInit()</tt> is called with a pointer to the structure to be initialized and
-the compression level, which is an integer in the range of -1 to 9. Lower compression
-levels result in faster execution, but less compression. Higher levels result in
-greater compression, but slower execution. The <em>zlib</em> constant Z_DEFAULT_COMPRESSION,
-equal to -1,
-provides a good compromise between compression and speed and is equivalent to level 6.
-Level 0 actually does no compression at all, and in fact expands the data slightly to produce
-the <em>zlib</em> format (it is not a byte-for-byte copy of the input).
-More advanced applications of <em>zlib</em>
-may use <tt>deflateInit2()</tt> here instead. Such an application may want to reduce how
-much memory will be used, at some price in compression. Or it may need to request a
-<em>gzip</em> header and trailer instead of a <em>zlib</em> header and trailer, or raw
-encoding with no header or trailer at all.
-<p>
-We must check the return value of <tt>deflateInit()</tt> against the <em>zlib</em> constant
-<tt>Z_OK</tt> to make sure that it was able to
-allocate memory for the internal state, and that the provided arguments were valid.
-<tt>deflateInit()</tt> will also check that the version of <em>zlib</em> that the <tt>zlib.h</tt>
-file came from matches the version of <em>zlib</em> actually linked with the program. This
-is especially important for environments in which <em>zlib</em> is a shared library.
-<p>
-Note that an application can initialize multiple, independent <em>zlib</em> streams, which can
-operate in parallel. The state information maintained in the structure allows the <em>zlib</em>
-routines to be reentrant.

-With the pleasantries out of the way, now we can get down to business. The outer <tt>do</tt>-loop
-reads all of the input file and exits at the bottom of the loop once end-of-file is reached.
-This loop contains the only call of <tt>deflate()</tt>. So we must make sure that all of the
-input data has been processed and that all of the output data has been generated and consumed
-before we fall out of the loop at the bottom.
-<pre><b>
- /* compress until end of file */
- do {
-</b></pre>
-We start off by reading data from the input file. The number of bytes read is put directly
-into <tt>avail_in</tt>, and a pointer to those bytes is put into <tt>next_in</tt>. We also
-check to see if end-of-file on the input has been reached. If we are at the end of file, then <tt>flush</tt> is set to the
-<em>zlib</em> constant <tt>Z_FINISH</tt>, which is later passed to <tt>deflate()</tt> to
-indicate that this is the last chunk of input data to compress. We need to use <tt>feof()</tt>
-to check for end-of-file as opposed to seeing if fewer than <tt>CHUNK</tt> bytes have been read. The
-reason is that if the input file length is an exact multiple of <tt>CHUNK</tt>, we will miss
-the fact that we got to the end-of-file, and not know to tell <tt>deflate()</tt> to finish
-up the compressed stream. If we are not yet at the end of the input, then the <em>zlib</em>
-constant <tt>Z_NO_FLUSH</tt> will be passed to <tt>deflate</tt> to indicate that we are still
-in the middle of the uncompressed data.
-<p>
-If there is an error in reading from the input file, the process is aborted with
-<tt>deflateEnd()</tt> being called to free the allocated <em>zlib</em> state before returning
-the error. We wouldn't want a memory leak, now would we? <tt>deflateEnd()</tt> can be called
-at any time after the state has been initialized. Once that's done, <tt>deflateInit()</tt> (or
-<tt>deflateInit2()</tt>) would have to be called to start a new compression process. There is
-no point here in checking the <tt>deflateEnd()</tt> return code. The deallocation can't fail.
-<pre><b>
- strm.avail_in = fread(in, 1, CHUNK, source);
- if (ferror(source)) {

- strm.next_in = in;
-</b></pre><!-- -->
-The inner <tt>do</tt>-loop passes our chunk of input data to <tt>deflate()</tt>, and then
-keeps calling <tt>deflate()</tt> until it is done producing output. Once there is no more
-new output, <tt>deflate()</tt> is guaranteed to have consumed all of the input, i.e.,
-<tt>avail_in</tt> will be zero.
-<pre><b>
- /* run deflate() on input until output buffer not full, finish
- compression if all of source has been read in */
- do {
-</b></pre>
-Output space is provided to <tt>deflate()</tt> by setting <tt>avail_out</tt> to the number
-of available output bytes and <tt>next_out</tt> to a pointer to that space.
-<pre><b>
- strm.avail_out = CHUNK;
- strm.next_out = out;
-</b></pre>
-Now we call the compression engine itself, <tt>deflate()</tt>. It takes as many of the
-<tt>avail_in</tt> bytes at <tt>next_in</tt> as it can process, and writes as many as
-<tt>avail_out</tt> bytes to <tt>next_out</tt>. Those counters and pointers are then
-updated past the input data consumed and the output data written. It is the amount of
-output space available that may limit how much input is consumed.
-Hence the inner loop to make sure that
-all of the input is consumed by providing more output space each time. Since <tt>avail_in</tt>
-and <tt>next_in</tt> are updated by <tt>deflate()</tt>, we don't have to mess with those
-between <tt>deflate()</tt> calls until it's all used up.
-<p>
-The parameters to <tt>deflate()</tt> are a pointer to the <tt>strm</tt> structure containing
-the input and output information and the internal compression engine state, and a parameter
-indicating whether and how to flush data to the output. Normally <tt>deflate</tt> will consume
-several K bytes of input data before producing any output (except for the header), in order
-to accumulate statistics on the data for optimum compression. It will then put out a burst of
-compressed data, and proceed to consume more input before the next burst. Eventually,
-<tt>deflate()</tt>
-must be told to terminate the stream, complete the compression with provided input data, and
-write out the trailer check value. <tt>deflate()</tt> will continue to compress normally as long
-as the flush parameter is <tt>Z_NO_FLUSH</tt>. Once the <tt>Z_FINISH</tt> parameter is provided,
-<tt>deflate()</tt> will begin to complete the compressed output stream. However depending on how
-much output space is provided, <tt>deflate()</tt> may have to be called several times until it
-has provided the complete compressed stream, even after it has consumed all of the input. The flush
-parameter must continue to be <tt>Z_FINISH</tt> for those subsequent calls.
-<p>
-There are other values of the flush parameter that are used in more advanced applications. You can
-force <tt>deflate()</tt> to produce a burst of output that encodes all of the input data provided
-so far, even if it wouldn't have otherwise, for example to control data latency on a link with
-compressed data. You can also ask that <tt>deflate()</tt> do that as well as erase any history up to
-that point so that what follows can be decompressed independently, for example for random access
-applications. Both requests will degrade compression by an amount depending on how often such
-requests are made.
-<p>
-<tt>deflate()</tt> has a return value that can indicate errors, yet we do not check it here. Why
-not? Well, it turns out that <tt>deflate()</tt> can do no wrong here. Let's go through
-<tt>deflate()</tt>'s return values and dispense with them one by one. The possible values are
-<tt>Z_OK</tt>, <tt>Z_STREAM_END</tt>, <tt>Z_STREAM_ERROR</tt>, or <tt>Z_BUF_ERROR</tt>. <tt>Z_OK</tt>
-is, well, ok. <tt>Z_STREAM_END</tt> is also ok and will be returned for the last call of
-<tt>deflate()</tt>. This is already guaranteed by calling <tt>deflate()</tt> with <tt>Z_FINISH</tt>
-until it has no more output. <tt>Z_STREAM_ERROR</tt> is only possible if the stream is not
-initialized properly, but we did initialize it properly. There is no harm in checking for
-<tt>Z_STREAM_ERROR</tt> here, for example to check for the possibility that some
-other part of the application inadvertently clobbered the memory containing the <em>zlib</em> state.
-<tt>Z_BUF_ERROR</tt> will be explained further below, but
-suffice it to say that this is simply an indication that <tt>deflate()</tt> could not consume
-more input or produce more output. <tt>deflate()</tt> can be called again with more output space
-or more available input, which it will be in this code.
-<pre><b>
- ret = deflate(&strm, flush); /* no bad return value */
- assert(ret != Z_STREAM_ERROR); /* state not clobbered */
-</b></pre>
-Now we compute how much output <tt>deflate()</tt> provided on the last call, which is the
-difference between how much space was provided before the call, and how much output space
-is still available after the call. Then that data, if any, is written to the output file.
-We can then reuse the output buffer for the next call of <tt>deflate()</tt>. Again if there
-is a file i/o error, we call <tt>deflateEnd()</tt> before returning to avoid a memory leak.
-<pre><b>
- have = CHUNK - strm.avail_out;
- if (fwrite(out, 1, have, dest) != have || ferror(dest)) {
- (void)deflateEnd(&strm);
- return Z_ERRNO;
- }
-</b></pre>
-The inner <tt>do</tt>-loop is repeated until the last <tt>deflate()</tt> call fails to fill the
-provided output buffer. Then we know that <tt>deflate()</tt> has done as much as it can with
-the provided input, and that all of that input has been consumed. We can then fall out of this
-loop and reuse the input buffer.
-<p>
-The way we tell that <tt>deflate()</tt> has no more output is by seeing that it did not fill
-the output buffer, leaving <tt>avail_out</tt> greater than zero. However suppose that
-<tt>deflate()</tt> has no more output, but just so happened to exactly fill the output buffer!
-<tt>avail_out</tt> is zero, and we can't tell that <tt>deflate()</tt> has done all it can.
-As far as we know, <tt>deflate()</tt>
-has more output for us. So we call it again. But now <tt>deflate()</tt> produces no output
-at all, and <tt>avail_out</tt> remains unchanged as <tt>CHUNK</tt>. That <tt>deflate()</tt> call
-wasn't able to do anything, either consume input or produce output, and so it returns
-<tt>Z_BUF_ERROR</tt>. (See, I told you I'd cover this later.) However this is not a problem at
-all. Now we finally have the desired indication that <tt>deflate()</tt> is really done,
-and so we drop out of the inner loop to provide more input to <tt>deflate()</tt>.
-<p>
-With <tt>flush</tt> set to <tt>Z_FINISH</tt>, this final set of <tt>deflate()</tt> calls will
-complete the output stream. Once that is done, subsequent calls of <tt>deflate()</tt> would return
-<tt>Z_STREAM_ERROR</tt> if the flush parameter is not <tt>Z_FINISH</tt>, and do no more processing
-until the state is reinitialized.
-<p>
-Some applications of <em>zlib</em> have two loops that call <tt>deflate()</tt>
-instead of the single inner loop we have here. The first loop would call
-without flushing and feed all of the data to <tt>deflate()</tt>. The second loop would call
-<tt>deflate()</tt> with no more
-data and the <tt>Z_FINISH</tt> parameter to complete the process. As you can see from this
-example, that can be avoided by simply keeping track of the current flush state.
-<pre><b>
- } while (strm.avail_out == 0);
- assert(strm.avail_in == 0); /* all input will be used */
-</b></pre><!-- -->
-Now we check to see if we have already processed all of the input file. That information was
-saved in the <tt>flush</tt> variable, so we see if that was set to <tt>Z_FINISH</tt>. If so,
-then we're done and we fall out of the outer loop. We're guaranteed to get <tt>Z_STREAM_END</tt>
-from the last <tt>deflate()</tt> call, since we ran it until the last chunk of input was
-consumed and all of the output was generated.
-<pre><b>
- /* done when last data in file processed */
- } while (flush != Z_FINISH);
- assert(ret == Z_STREAM_END); /* stream will be complete */
-</b></pre><!-- -->
-The process is complete, but we still need to deallocate the state to avoid a memory leak
-(or rather more like a memory hemorrhage if you didn't do this). Then
-finally we can return with a happy return value.
-<pre><b>
- /* clean up and return */
- (void)deflateEnd(&strm);
- return Z_OK;
-}

-Now we do the same thing for decompression in the <tt>inf()</tt> routine. <tt>inf()</tt>
-decompresses what is hopefully a valid <em>zlib</em> stream from the input file and writes the
-uncompressed data to the output file. Much of the discussion above for <tt>def()</tt>

-of course, and two more elements of the structure are initialized. <tt>avail_in</tt>
-and <tt>next_in</tt> must be initialized before calling <tt>inflateInit()</tt>. This
-is because the application has the option to provide the start of the zlib stream in
-order for <tt>inflateInit()</tt> to have access to information about the compression
-method to aid in memory allocation. In the current implementation of <em>zlib</em>
-(up through versions 1.2.x), the method-dependent memory allocations are deferred to the first call of
-<tt>inflate()</tt> anyway. However those fields must be initialized since later versions
-of <em>zlib</em> that provide more compression methods may take advantage of this interface.
-In any case, no decompression is performed by <tt>inflateInit()</tt>, so the
-<tt>avail_out</tt> and <tt>next_out</tt> fields do not need to be initialized before calling.

-indicates that <tt>inflate()</tt> detected an error in the <em>zlib</em> compressed data format,
-which means that either the data is not a <em>zlib</em> stream to begin with, or that the data was
-corrupted somewhere along the way since it was compressed. The other error to be processed is
-<tt>Z_MEM_ERROR</tt>, which can occur since memory allocation is deferred until <tt>inflate()</tt>
-needs it, unlike <tt>deflate()</tt>, whose memory is allocated at the start by <tt>deflateInit()</tt>.

- Version 1.0 29 May 2005 Mark Adler */

-/* Illustrate the use of Z_BLOCK, inflatePrime(), and inflateSetDictionary()
- for random access of a compressed file. A file containing a zlib or gzip
- stream is provided on the command line. The compressed stream is decoded in
- its entirety, and an index built with access points about every SPAN bytes
- in the uncompressed output. The compressed file is left open, and can then
- be read randomly, having to decompress on the average SPAN/2 uncompressed
- bytes before getting to the desired block of data.
-
- An access point can be created at the start of any deflate block, by saving
- the starting file offset and bit of that block, and the 32K bytes of
- uncompressed data that precede that block. Also the uncompressed offset of
- that block is saved to provide a referece for locating a desired starting
- point in the uncompressed stream. build_index() works by decompressing the
- input zlib or gzip stream a block at a time, and at the end of each block
- deciding if enough uncompressed data has gone by to justify the creation of
- a new access point. If so, that point is saved in a data structure that
- grows as needed to accommodate the points.
-
- To use the index, an offset in the uncompressed data is provided, for which
- the latest accees point at or preceding that offset is located in the index.
- The input file is positioned to the specified location in the index, and if
- necessary the first few bits of the compressed data is read from the file.
- inflate is initialized with those bits and the 32K of uncompressed data, and
- the decompression then proceeds until the desired offset in the file is
- reached. Then the decompression continues to read the desired uncompressed
- data from the file.
-
- Another approach would be to generate the index on demand. In that case,
- requests for random access reads from the compressed data would try to use
- the index, but if a read far enough past the end of the index is required,
- then further index entries would be generated and added.
-
- There is some fair bit of overhead to starting inflation for the random
- access, mainly copying the 32K byte dictionary. So if small pieces of the
- file are being accessed, it would make sense to implement a cache to hold
- some lookahead and avoid many calls to extract() for small lengths.
-
- Another way to build an index would be to use inflateCopy(). That would
- not be constrained to have access points at block boundaries, but requires
- more memory per access point, and also cannot be saved to file due to the
- use of pointers in the state. The approach here allows for storage of the
- index in a file.

- strm provides the memory allocation functions and window buffer on input,
- and provides information on the unused input on return. For Z_DATA_ERROR
- returns, strm will also provide an error message.
-
- in() and out() are the call-back input and output functions. When
- inflateBack() needs more input, it calls in(). When inflateBack() has
- filled the window with output, or when it completes with data in the
- window, it calls out() to write out the data. The application must not
- change the provided input until in() is called again or inflateBack()
- returns. The application must not change the window/output buffer until
- inflateBack() returns.
-
- in() and out() are called with a descriptor parameter provided in the
- inflateBack() call. This parameter can be a structure that provides the
- information required to do the read or write, as well as accumulated
- information on the input and output such as totals and check values.
-
- in() should return zero on failure. out() should return non-zero on
- failure. If either in() or out() fails, than inflateBack() returns a
- Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
- was in() or out() that caused in the error. Otherwise, inflateBack()
- returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
- error, or Z_MEM_ERROR if it could not allocate memory for the state.
- inflateBack() can also return Z_STREAM_ERROR if the input parameters
- are not correct, i.e. strm is Z_NULL or the state was not initialized.

- Decode literal, length, and distance codes and write out the resulting
- literal and match bytes until either not enough input or output is
- available, an end-of-block is encountered, or a data error is encountered.
- When large enough input and output buffers are supplied to inflate(), for
- example, a 16K input buffer and a 64K output buffer, more than 95% of the
- inflate execution time is spent in this routine.
-
- Entry assumptions:
-
- state->mode == LEN
- strm->avail_in >= 6
- strm->avail_out >= 258
- start >= strm->avail_out
- state->bits < 8
-
- On return, state->mode is one of:
-
- LEN -- ran out of enough output space or enough available input
- TYPE -- reached end of block code, inflate() to interpret next block
- BAD -- error in block data
-
- Notes:
-
- - The maximum input bits used by a length/distance pair is 15 bits for the
- length code, 5 bits for the length extra, 15 bits for the distance code,
- and 13 bits for the distance extra. This totals 48 bits, or six bytes.
- Therefore if strm->avail_in >= 6, then there is enough input to avoid
- checking for available input while decoding.
-
- - The maximum bytes that a single length/distance pair can output is 258
- bytes, which is the maximum length that can be coded. inflate_fast()
- requires strm->avail_out >= 258 for each loop to avoid checking for
- output space.

- */
-
-/*
- * Change history:
- *
- * 1.2.beta0 24 Nov 2002
- * - First version -- complete rewrite of inflate to simplify code, avoid
- * creation of window when not needed, minimize use of window when it is
- * needed, make inffast.c even faster, implement gzip decoding, and to
- * improve code readability and style over the previous zlib inflate code
- *
- * 1.2.beta1 25 Nov 2002
- * - Use pointers for available input and output checking in inffast.c
- * - Remove input and output counters in inffast.c
- * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
- * - Remove unnecessary second byte pull from length extra in inffast.c
- * - Unroll direct copy to three copies per loop in inffast.c
- *
- * 1.2.beta2 4 Dec 2002
- * - Change external routine names to reduce potential conflicts
- * - Correct filename to inffixed.h for fixed tables in inflate.c
- * - Make hbuf[] unsigned char to match parameter type in inflate.c
- * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
- * to avoid negation problem on Alphas (64 bit) in inflate.c
- *
- * 1.2.beta3 22 Dec 2002
- * - Add comments on state->bits assertion in inffast.c
- * - Add comments on op field in inftrees.h
- * - Fix bug in reuse of allocated window after inflateReset()
- * - Remove bit fields--back to byte structure for speed
- * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
- * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
- * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
- * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
- * - Use local copies of stream next and avail values, as well as local bit
- * buffer and bit count in inflate()--for speed when inflate_fast() not used
- *
- * 1.2.beta4 1 Jan 2003
- * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
- * - Move a comment on output buffer sizes from inffast.c to inflate.c
- * - Add comments in inffast.c to introduce the inflate_fast() routine
- * - Rearrange window copies in inflate_fast() for speed and simplification
- * - Unroll last copy for window match in inflate_fast()
- * - Use local copies of window variables in inflate_fast() for speed
- * - Pull out common wnext == 0 case for speed in inflate_fast()
- * - Make op and len in inflate_fast() unsigned for consistency
- * - Add FAR to lcode and dcode declarations in inflate_fast()
- * - Simplified bad distance check in inflate_fast()
- * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
- * source file infback.c to provide a call-back interface to inflate for
- * programs like gzip and unzip -- uses window as output buffer to avoid
- * window copying
- *
- * 1.2.beta5 1 Jan 2003
- * - Improved inflateBack() interface to allow the caller to provide initial
- * input in strm.
- * - Fixed stored blocks bug in inflateBack()
- *
- * 1.2.beta6 4 Jan 2003
- * - Added comments in inffast.c on effectiveness of POSTINC
- * - Typecasting all around to reduce compiler warnings
- * - Changed loops from while (1) or do {} while (1) to for (;;), again to
- * make compilers happy
- * - Changed type of window in inflateBackInit() to unsigned char *
- *
- * 1.2.beta7 27 Jan 2003
- * - Changed many types to unsigned or unsigned short to avoid warnings
- * - Added inflateCopy() function
- *
- * 1.2.0 9 Mar 2003
- * - Changed inflateBack() interface to provide separate opaque descriptors
- * for the in() and out() functions
- * - Changed inflateBack() argument and in_func typedef to swap the length
- * and buffer address return values for the input function
- * - Check next_in and next_out for Z_NULL on entry to inflate()
- *
- * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

- inflate() uses a state machine to process as much input data and generate as
- much output data as possible before returning. The state machine is
- structured roughly as follows:
-
- for (;;) switch (state) {
- ...
- case STATEn:
- if (not enough input data or output space to make progress)
- return;
- ... make progress ...
- state = STATEm;
- break;
- ...
- }
-
- so when inflate() is called again, the same case is attempted again, and
- if the appropriate resources are provided, the machine proceeds to the
- next state. The NEEDBITS() macro is usually the way the state evaluates
- whether it can proceed or should return. NEEDBITS() does the return if
- the requested bits are not available. The typical use of the BITS macros
- is:
-
- NEEDBITS(n);
- ... do something with BITS(n) ...
- DROPBITS(n);
-
- where NEEDBITS(n) either returns from inflate() if there isn't enough
- input left to load n bits into the accumulator, or it continues. BITS(n)
- gives the low n bits in the accumulator. When done, DROPBITS(n) drops
- the low n bits off the accumulator. INITBITS() clears the accumulator
- and sets the number of available bits to zero. BYTEBITS() discards just
- enough bits to put the accumulator on a byte boundary. After BYTEBITS()
- and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
-
- NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
- if there is no input available. The decoding of variable length codes uses
- PULLBYTE() directly in order to pull just enough bytes to decode the next
- code, and no more.
-
- Some states loop until they get enough input, making sure that enough
- state information is maintained to continue the loop where it left off
- if NEEDBITS() returns in the loop. For example, want, need, and keep
- would all have to actually be part of the saved state in case NEEDBITS()
- returns:
-
- case STATEw:
- while (want < need) {
- NEEDBITS(n);
- keep[want++] = BITS(n);
- DROPBITS(n);
- }
- state = STATEx;
- case STATEx:
-
- As shown above, if the next state is also the next case, then the break
- is omitted.
-
- A state may also return if there is not enough output space available to
- complete that state. Those states are copying stored data, writing a
- literal byte, and copying a matching string.
-
- When returning, a "goto inf_leave" is used to update the total counters,
- update the check value, and determine whether any progress has been made
- during that inflate() call in order to return the proper return code.
- Progress is defined as a change in either strm->avail_in or strm->avail_out.
- When there is a window, goto inf_leave will update the window with the last
- output written. If a goto inf_leave occurs in the middle of decompression
- and there is no window currently, goto inf_leave will create one and copy
- output to the window for the next call of inflate().
-
- In this implementation, the flush parameter of inflate() only affects the
- return code (per zlib.h). inflate() always writes as much as possible to
- strm->next_out, given the space available and the provided input--the effect
- documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers
- the allocation of and copying into a sliding window until necessary, which
- provides the effect documented in zlib.h for Z_FINISH when the entire input
- stream available. So the only thing the flush parameter actually does is:
- when flush is set to Z_FINISH, inflate() cannot return Z_OK. Instead it
- will return Z_BUF_ERROR if it has not reached the end of the stream.

- Process a set of code lengths to create a canonical Huffman code. The

- symbols by length from short to long, and retaining the symbol order
- for codes with equal lengths. Then the code starts with all zero bits
- for the first code of the shortest length, and the codes are integer
- increments for the same length, and zeros are appended as the length
- increases. For the deflate format, these bits are stored backwards
- from their more natural integer increment ordering, and so when the
- decoding tables are built in the large loop below, the integer codes
- are incremented backwards.
-
- This routine assumes, but does not check, that all of the entries in
- lens[] are in the range 0..MAXBITS. The caller must assure this.
- 1..MAXBITS is interpreted as that code length. zero means that that
- symbol does not occur in this code.
-
- The codes are sorted by computing a count of codes for each length,
- creating from that a table of starting indices for each length in the
- sorted table, and then entering the symbols in order in the sorted
- table. The sorted table is work[], with that space being provided by
- the caller.
-
- The length counts are used for other purposes as well, i.e. finding

- codes at all, checking for a valid set of lengths, and looking ahead
- at length counts to determine sub-table sizes when building the

- When a new sub-table is needed, it is necessary to look ahead in the

-See below some functions declarations for Visual Basic.
-
-Frequently Asked Question:
-
-Q: Each time I use the compress function I get the -5 error (not enough
- room in the output buffer).
-
-A: Make sure that the length of the compressed buffer is passed by
- reference ("as any"), not by value ("as long"). Also check that
- before the call of compress this length is equal to the total size of
- the compressed buffer and not zero.

-Here is another example from Michael <michael_borgsys@hotmail.com> that he
-says conforms to the VB guidelines, and that solves the problem of not
-knowing the uncompressed size by storing it at the end of the file:
-
-'Calling the functions:
-'bracket meaning: <parameter> [optional] {Range of possible values}
-'Call subCompressFile(<path with filename to compress> [, <path with
-filename to write to>, [level of compression {1..9}]])
-'Call subUncompressFile(<path with filename to compress>)
-

-
-/*
- These memory tracking routines are provided to zlib and track all of zlib's
- allocations and deallocations, check for LIFO operations, keep a current
- and high water mark of total bytes requested, optionally set a limit on the
- total memory that can be allocated, and when done check for memory leaks.
-
- They are used as follows:
-
- z_stream strm;
- mem_setup(&strm) initializes the memory tracking and sets the
- zalloc, zfree, and opaque members of strm to use
- memory tracking for all zlib operations on strm
- mem_limit(&strm, limit) sets a limit on the total bytes requested -- a
- request that exceeds this limit will result in an
- allocation failure (returns NULL) -- setting the
- limit to zero means no limit, which is the default
- after mem_setup()
- mem_used(&strm, "msg") prints to stderr "msg" and the total bytes used
- mem_high(&strm, "msg") prints to stderr "msg" and the high water mark
- mem_done(&strm, "msg") ends memory tracking, releases all allocations
- for the tracking as well as leaked zlib blocks, if
- any. If there was anything unusual, such as leaked
- blocks, non-FIFO frees, or frees of addresses not
- allocated, then "msg" and information about the
- problem is printed to stderr. If everything is
- normal, nothing is printed. mem_done resets the
- strm members to Z_NULL to use the default memory
- allocation routines on the next zlib initialization
- using strm.

- * ALGORITHM
- *
- * The "deflation" process uses several Huffman trees. The more
- * common source values are represented by shorter bit sequences.
- *
- * Each code tree is stored in a compressed form which is itself
- * a Huffman encoding of the lengths of all the code strings (in
- * ascending order by source values). The actual code strings are
- * reconstructed from the lengths in the inflate process, as described
- * in the deflate specification.

- Frequently Asked Questions about ZLIB1.DLL
-
-
-This document describes the design, the rationale, and the usage
-of the official DLL build of zlib, named ZLIB1.DLL. If you have
-general questions about zlib, you should see the file "FAQ" found
-in the zlib distribution, or at the following location:
- http://www.gzip.org/zlib/zlib_faq.html
-
-
- 1. What is ZLIB1.DLL, and how can I get it?
-
- - ZLIB1.DLL is the official build of zlib as a DLL.
- (Please remark the character '1' in the name.)
-
- Pointers to a precompiled ZLIB1.DLL can be found in the zlib
- web site at:
- http://www.zlib.net/
-
- Applications that link to ZLIB1.DLL can rely on the following
- specification:
-
- * The exported symbols are exclusively defined in the source
- files "zlib.h" and "zlib.def", found in an official zlib
- source distribution.
- * The symbols are exported by name, not by ordinal.
- * The exported names are undecorated.
- * The calling convention of functions is "C" (CDECL).
- * The ZLIB1.DLL binary is linked to MSVCRT.DLL.
-
- The archive in which ZLIB1.DLL is bundled contains compiled
- test programs that must run with a valid build of ZLIB1.DLL.
- It is recommended to download the prebuilt DLL from the zlib
- web site, instead of building it yourself, to avoid potential
- incompatibilities that could be introduced by your compiler
- and build settings. If you do build the DLL yourself, please
- make sure that it complies with all the above requirements,
- and it runs with the precompiled test programs, bundled with
- the original ZLIB1.DLL distribution.
-
- If, for any reason, you need to build an incompatible DLL,
- please use a different file name.
-
-
- 2. Why did you change the name of the DLL to ZLIB1.DLL?
- What happened to the old ZLIB.DLL?
-
- - The old ZLIB.DLL, built from zlib-1.1.4 or earlier, required
- compilation settings that were incompatible to those used by
- a static build. The DLL settings were supposed to be enabled
- by defining the macro ZLIB_DLL, before including "zlib.h".
- Incorrect handling of this macro was silently accepted at
- build time, resulting in two major problems:
-
- * ZLIB_DLL was missing from the old makefile. When building
- the DLL, not all people added it to the build options. In
- consequence, incompatible incarnations of ZLIB.DLL started
- to circulate around the net.
-
- * When switching from using the static library to using the
- DLL, applications had to define the ZLIB_DLL macro and
- to recompile all the sources that contained calls to zlib
- functions. Failure to do so resulted in creating binaries
- that were unable to run with the official ZLIB.DLL build.
-
- The only possible solution that we could foresee was to make
- a binary-incompatible change in the DLL interface, in order to
- remove the dependency on the ZLIB_DLL macro, and to release
- the new DLL under a different name.
-
- We chose the name ZLIB1.DLL, where '1' indicates the major
- zlib version number. We hope that we will not have to break
- the binary compatibility again, at least not as long as the
- zlib-1.x series will last.
-
- There is still a ZLIB_DLL macro, that can trigger a more
- efficient build and use of the DLL, but compatibility no
- longer dependents on it.
-
-
- 3. Can I build ZLIB.DLL from the new zlib sources, and replace
- an old ZLIB.DLL, that was built from zlib-1.1.4 or earlier?
-
- - In principle, you can do it by assigning calling convention
- keywords to the macros ZEXPORT and ZEXPORTVA. In practice,
- it depends on what you mean by "an old ZLIB.DLL", because the
- old DLL exists in several mutually-incompatible versions.
- You have to find out first what kind of calling convention is
- being used in your particular ZLIB.DLL build, and to use the
- same one in the new build. If you don't know what this is all
- about, you might be better off if you would just leave the old
- DLL intact.
-
-
- 4. Can I compile my application using the new zlib interface, and
- link it to an old ZLIB.DLL, that was built from zlib-1.1.4 or
- earlier?
-
- - The official answer is "no"; the real answer depends again on
- what kind of ZLIB.DLL you have. Even if you are lucky, this
- course of action is unreliable.
-
- If you rebuild your application and you intend to use a newer
- version of zlib (post- 1.1.4), it is strongly recommended to
- link it to the new ZLIB1.DLL.
-
-
- 5. Why are the zlib symbols exported by name, and not by ordinal?
-
- - Although exporting symbols by ordinal is a little faster, it
- is risky. Any single glitch in the maintenance or use of the
- DEF file that contains the ordinals can result in incompatible
- builds and frustrating crashes. Simply put, the benefits of
- exporting symbols by ordinal do not justify the risks.
-
- Technically, it should be possible to maintain ordinals in
- the DEF file, and still export the symbols by name. Ordinals
- exist in every DLL, and even if the dynamic linking performed
- at the DLL startup is searching for names, ordinals serve as
- hints, for a faster name lookup. However, if the DEF file
- contains ordinals, the Microsoft linker automatically builds
- an implib that will cause the executables linked to it to use
- those ordinals, and not the names. It is interesting to
- notice that the GNU linker for Win32 does not suffer from this
- problem.
-
- It is possible to avoid the DEF file if the exported symbols
- are accompanied by a "__declspec(dllexport)" attribute in the
- source files. You can do this in zlib by predefining the
- ZLIB_DLL macro.
-
-
- 6. I see that the ZLIB1.DLL functions use the "C" (CDECL) calling
- convention. Why not use the STDCALL convention?
- STDCALL is the standard convention in Win32, and I need it in
- my Visual Basic project!
-
- (For readability, we use CDECL to refer to the convention
- triggered by the "__cdecl" keyword, STDCALL to refer to
- the convention triggered by "__stdcall", and FASTCALL to
- refer to the convention triggered by "__fastcall".)
-
- - Most of the native Windows API functions (without varargs) use
- indeed the WINAPI convention (which translates to STDCALL in
- Win32), but the standard C functions use CDECL. If a user
- application is intrinsically tied to the Windows API (e.g.
- it calls native Windows API functions such as CreateFile()),
- sometimes it makes sense to decorate its own functions with
- WINAPI. But if ANSI C or POSIX portability is a goal (e.g.
- it calls standard C functions such as fopen()), it is not a
- sound decision to request the inclusion of <windows.h>, or to
- use non-ANSI constructs, for the sole purpose to make the user
- functions STDCALL-able.
-
- The functionality offered by zlib is not in the category of
- "Windows functionality", but is more like "C functionality".
-
- Technically, STDCALL is not bad; in fact, it is slightly
- faster than CDECL, and it works with variable-argument
- functions, just like CDECL. It is unfortunate that, in spite
- of using STDCALL in the Windows API, it is not the default
- convention used by the C compilers that run under Windows.
- The roots of the problem reside deep inside the unsafety of
- the K&R-style function prototypes, where the argument types
- are not specified; but that is another story for another day.
-
- The remaining fact is that CDECL is the default convention.
- Even if an explicit convention is hard-coded into the function
- prototypes inside C headers, problems may appear. The
- necessity to expose the convention in users' callbacks is one
- of these problems.
-
- The calling convention issues are also important when using
- zlib in other programming languages. Some of them, like Ada
- (GNAT) and Fortran (GNU G77), have C bindings implemented
- initially on Unix, and relying on the C calling convention.
- On the other hand, the pre- .NET versions of Microsoft Visual
- Basic require STDCALL, while Borland Delphi prefers, although
- it does not require, FASTCALL.
-
- In fairness to all possible uses of zlib outside the C
- programming language, we choose the default "C" convention.
- Anyone interested in different bindings or conventions is
- encouraged to maintain specialized projects. The "contrib/"
- directory from the zlib distribution already holds a couple
- of foreign bindings, such as Ada, C++, and Delphi.
-
-
- 7. I need a DLL for my Visual Basic project. What can I do?
-
- - Define the ZLIB_WINAPI macro before including "zlib.h", when
- building both the DLL and the user application (except that
- you don't need to define anything when using the DLL in Visual
- Basic). The ZLIB_WINAPI macro will switch on the WINAPI
- (STDCALL) convention. The name of this DLL must be different
- than the official ZLIB1.DLL.
-
- Gilles Vollant has contributed a build named ZLIBWAPI.DLL,
- with the ZLIB_WINAPI macro turned on, and with the minizip
- functionality built in. For more information, please read
- the notes inside "contrib/vstudio/readme.txt", found in the
- zlib distribution.
-
-
- 8. I need to use zlib in my Microsoft .NET project. What can I
- do?
-
- - Henrik Ravn has contributed a .NET wrapper around zlib. Look
- into contrib/dotzlib/, inside the zlib distribution.
-
-
- 9. If my application uses ZLIB1.DLL, should I link it to
- MSVCRT.DLL? Why?
-
- - It is not required, but it is recommended to link your
- application to MSVCRT.DLL, if it uses ZLIB1.DLL.
-
- The executables (.EXE, .DLL, etc.) that are involved in the
- same process and are using the C run-time library (i.e. they
- are calling standard C functions), must link to the same
- library. There are several libraries in the Win32 system:
- CRTDLL.DLL, MSVCRT.DLL, the static C libraries, etc.
- Since ZLIB1.DLL is linked to MSVCRT.DLL, the executables that
- depend on it should also be linked to MSVCRT.DLL.
-
-
-10. Why are you saying that ZLIB1.DLL and my application should
- be linked to the same C run-time (CRT) library? I linked my
- application and my DLLs to different C libraries (e.g. my
- application to a static library, and my DLLs to MSVCRT.DLL),
- and everything works fine.
-
- - If a user library invokes only pure Win32 API (accessible via
- <windows.h> and the related headers), its DLL build will work
- in any context. But if this library invokes standard C API,
- things get more complicated.
-
- There is a single Win32 library in a Win32 system. Every
- function in this library resides in a single DLL module, that
- is safe to call from anywhere. On the other hand, there are
- multiple versions of the C library, and each of them has its
- own separate internal state. Standalone executables and user
- DLLs that call standard C functions must link to a C run-time
- (CRT) library, be it static or shared (DLL). Intermixing
- occurs when an executable (not necessarily standalone) and a
- DLL are linked to different CRTs, and both are running in the
- same process.
-
- Intermixing multiple CRTs is possible, as long as their
- internal states are kept intact. The Microsoft Knowledge Base
- articles KB94248 "HOWTO: Use the C Run-Time" and KB140584
- "HOWTO: Link with the Correct C Run-Time (CRT) Library"
- mention the potential problems raised by intermixing.
-
- If intermixing works for you, it's because your application
- and DLLs are avoiding the corruption of each of the CRTs'
- internal states, maybe by careful design, or maybe by fortune.
-
- Also note that linking ZLIB1.DLL to non-Microsoft CRTs, such
- as those provided by Borland, raises similar problems.
-
-
-11. Why are you linking ZLIB1.DLL to MSVCRT.DLL?
-
- - MSVCRT.DLL exists on every Windows 95 with a new service pack
- installed, or with Microsoft Internet Explorer 4 or later, and
- on all other Windows 4.x or later (Windows 98, Windows NT 4,
- or later). It is freely distributable; if not present in the
- system, it can be downloaded from Microsoft or from other
- software provider for free.
-
- The fact that MSVCRT.DLL does not exist on a virgin Windows 95
- is not so problematic. Windows 95 is scarcely found nowadays,
- Microsoft ended its support a long time ago, and many recent
- applications from various vendors, including Microsoft, do not
- even run on it. Furthermore, no serious user should run
- Windows 95 without a proper update installed.
-
-
-12. Why are you not linking ZLIB1.DLL to
- <<my favorite C run-time library>> ?
-
- - We considered and abandoned the following alternatives:
-
- * Linking ZLIB1.DLL to a static C library (LIBC.LIB, or
- LIBCMT.LIB) is not a good option. People are using the DLL
- mainly to save disk space. If you are linking your program
- to a static C library, you may as well consider linking zlib
- in statically, too.
-
- * Linking ZLIB1.DLL to CRTDLL.DLL looks appealing, because
- CRTDLL.DLL is present on every Win32 installation.
- Unfortunately, it has a series of problems: it does not
- work properly with Microsoft's C++ libraries, it does not
- provide support for 64-bit file offsets, (and so on...),
- and Microsoft discontinued its support a long time ago.
-
- * Linking ZLIB1.DLL to MSVCR70.DLL or MSVCR71.DLL, supplied
- with the Microsoft .NET platform, and Visual C++ 7.0/7.1,
- raises problems related to the status of ZLIB1.DLL as a
- system component. According to the Microsoft Knowledge Base
- article KB326922 "INFO: Redistribution of the Shared C
- Runtime Component in Visual C++ .NET", MSVCR70.DLL and
- MSVCR71.DLL are not supposed to function as system DLLs,
- because they may clash with MSVCRT.DLL. Instead, the
- application's installer is supposed to put these DLLs
- (if needed) in the application's private directory.
- If ZLIB1.DLL depends on a non-system runtime, it cannot
- function as a redistributable system component.
-
- * Linking ZLIB1.DLL to non-Microsoft runtimes, such as
- Borland's, or Cygwin's, raises problems related to the
- reliable presence of these runtimes on Win32 systems.
- It's easier to let the DLL build of zlib up to the people
- who distribute these runtimes, and who may proceed as
- explained in the answer to Question 14.
-
-
-13. If ZLIB1.DLL cannot be linked to MSVCR70.DLL or MSVCR71.DLL,
- how can I build/use ZLIB1.DLL in Microsoft Visual C++ 7.0
- (Visual Studio .NET) or newer?
-
- - Due to the problems explained in the Microsoft Knowledge Base
- article KB326922 (see the previous answer), the C runtime that
- comes with the VC7 environment is no longer considered a
- system component. That is, it should not be assumed that this
- runtime exists, or may be installed in a system directory.
- Since ZLIB1.DLL is supposed to be a system component, it may
- not depend on a non-system component.
-
- In order to link ZLIB1.DLL and your application to MSVCRT.DLL
- in VC7, you need the library of Visual C++ 6.0 or older. If
- you don't have this library at hand, it's probably best not to
- use ZLIB1.DLL.
-
- We are hoping that, in the future, Microsoft will provide a
- way to build applications linked to a proper system runtime,
- from the Visual C++ environment. Until then, you have a
- couple of alternatives, such as linking zlib in statically.
- If your application requires dynamic linking, you may proceed
- as explained in the answer to Question 14.
-
-
-14. I need to link my own DLL build to a CRT different than
- MSVCRT.DLL. What can I do?
-
- - Feel free to rebuild the DLL from the zlib sources, and link
- it the way you want. You should, however, clearly state that
- your build is unofficial. You should give it a different file
- name, and/or install it in a private directory that can be
- accessed by your application only, and is not visible to the
- others (i.e. it's neither in the PATH, nor in the SYSTEM or
- SYSTEM32 directories). Otherwise, your build may clash with
- applications that link to the official build.
-
- For example, in Cygwin, zlib is linked to the Cygwin runtime
- CYGWIN1.DLL, and it is distributed under the name CYGZ.DLL.
-
-
-15. May I include additional pieces of code that I find useful,
- link them in ZLIB1.DLL, and export them?
-
- - No. A legitimate build of ZLIB1.DLL must not include code
- that does not originate from the official zlib source code.
- But you can make your own private DLL build, under a different
- file name, as suggested in the previous answer.
-
- For example, zlib is a part of the VCL library, distributed
- with Borland Delphi and C++ Builder. The DLL build of VCL
- is a redistributable file, named VCLxx.DLL.
-
-
-16. May I remove some functionality out of ZLIB1.DLL, by enabling
- macros like NO_GZCOMPRESS or NO_GZIP at compile time?
-
- - No. A legitimate build of ZLIB1.DLL must provide the complete
- zlib functionality, as implemented in the official zlib source
- code. But you can make your own private DLL build, under a
- different file name, as suggested in the previous answer.
-
-
-17. I made my own ZLIB1.DLL build. Can I test it for compliance?
-
- - We prefer that you download the official DLL from the zlib
- web site. If you need something peculiar from this DLL, you
- can send your suggestion to the zlib mailing list.
-
- However, in case you do rebuild the DLL yourself, you can run
- it with the test programs found in the DLL distribution.
- Running these test programs is not a guarantee of compliance,
- but a failure can imply a detected problem.

-ZLIB DATA COMPRESSION LIBRARY
-
-zlib 1.2.7 is a general purpose data compression library. All the code is
-thread safe. The data format used by the zlib library is described by RFCs
-(Request for Comments) 1950 to 1952 in the files
-http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
-and rfc1952.txt (gzip format).
-
-All functions of the compression library are documented in the file zlib.h
-(volunteer to write man pages welcome, contact zlib@gzip.org). Two compiled
-examples are distributed in this package, example and minigzip. The example_d
-and minigzip_d flavors validate that the zlib1.dll file is working correctly.
-
-Questions about zlib should be sent to <zlib@gzip.org>. The zlib home page
-is http://zlib.net/ . Before reporting a problem, please check this site to
-verify that you have the latest version of zlib; otherwise get the latest
-version and check whether the problem still exists or not.
-
-PLEASE read DLL_FAQ.txt, and the the zlib FAQ http://zlib.net/zlib_faq.html
-before asking for help.
-
-
-Manifest:
-
-The package zlib-1.2.7-win32-x86.zip will contain the following files:
-
- README-WIN32.txt This document
- ChangeLog Changes since previous zlib packages
- DLL_FAQ.txt Frequently asked questions about zlib1.dll
- zlib.3.pdf Documentation of this library in Adobe Acrobat format
-
- example.exe A statically-bound example (using zlib.lib, not the dll)
- example.pdb Symbolic information for debugging example.exe
-
- example_d.exe A zlib1.dll bound example (using zdll.lib)
- example_d.pdb Symbolic information for debugging example_d.exe
-
- minigzip.exe A statically-bound test program (using zlib.lib, not the dll)
- minigzip.pdb Symbolic information for debugging minigzip.exe
-
- minigzip_d.exe A zlib1.dll bound test program (using zdll.lib)
- minigzip_d.pdb Symbolic information for debugging minigzip_d.exe
-
- zlib.h Install these files into the compilers' INCLUDE path to
- zconf.h compile programs which use zlib.lib or zdll.lib
-
- zdll.lib Install these files into the compilers' LIB path if linking
- zdll.exp a compiled program to the zlib1.dll binary
-
- zlib.lib Install these files into the compilers' LIB path to link zlib
- zlib.pdb into compiled programs, without zlib1.dll runtime dependency
- (zlib.pdb provides debugging info to the compile time linker)
-
- zlib1.dll Install this binary shared library into the system PATH, or
- the program's runtime directory (where the .exe resides)
- zlib1.pdb Install in the same directory as zlib1.dll, in order to debug
- an application crash using WinDbg or similar tools.
-
-All .pdb files above are entirely optional, but are very useful to a developer
-attempting to diagnose program misbehavior or a crash. Many additional
-important files for developers can be found in the zlib127.zip source package
-available from http://zlib.net/ - review that package's README file for details.
-
-
-Acknowledgments:
-
-The deflate format used by zlib was defined by Phil Katz. The deflate and
-zlib specifications were written by L. Peter Deutsch. Thanks to all the
-people who reported problems and suggested various improvements in zlib; they
-are too numerous to cite here.

-.TH ZLIB 3 "2 May 2012"
-.SH NAME
-zlib \- compression/decompression library
-.SH SYNOPSIS
-[see
-.I zlib.h
-for full description]
-.SH DESCRIPTION
-The
-.I zlib
-library is a general purpose data compression library.
-The code is thread safe, assuming that the standard library functions
-used are thread safe, such as memory allocation routines.
-It provides in-memory compression and decompression functions,
-including integrity checks of the uncompressed data.
-This version of the library supports only one compression method (deflation)
-but other algorithms may be added later
-with the same stream interface.
-.LP
-Compression can be done in a single step if the buffers are large enough
-or can be done by repeated calls of the compression function.
-In the latter case,
-the application must provide more input and/or consume the output
-(providing more output space) before each call.
-.LP
-The library also supports reading and writing files in
-.IR gzip (1)
-(.gz) format
-with an interface similar to that of stdio.
-.LP
-The library does not install any signal handler.
-The decoder checks the consistency of the compressed data,
-so the library should never crash even in the case of corrupted input.
-.LP
-All functions of the compression library are documented in the file
-.IR zlib.h .
-The distribution source includes examples of use of the library
-in the files
-.I test/example.c
-and
-.IR test/minigzip.c,
-as well as other examples in the
-.IR examples/
-directory.

- around a deflate stream, which is itself documented in RFC 1951.
-
- The library also supports reading and writing files in gzip (.gz) format
- with an interface similar to that of stdio using the functions that start
- with "gz". The gzip format is different from the zlib format. gzip is a
- gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
-
- This library can optionally read and write gzip streams in memory as well.
-
- The zlib format was designed to be compact and fast for use in memory
- and on communications channels. The gzip format was designed for single-
- file compression on file systems, has a larger header than zlib to maintain
- directory information, and uses a different, slower check method than zlib.
-
- The library does not install any signal handler. The decoder checks
- the consistency of the compressed data, so the library should never crash
- even in case of corrupted input.

- The application must update next_in and avail_in when avail_in has dropped

- to zero. The application must initialize zalloc, zfree and opaque before
- calling the init function. All other fields are set by the compression
- library and must not be updated by the application.
-
- The opaque value provided by the application will be passed as the first
- parameter for calls of zalloc and zfree. This can be useful for custom
- memory management. The compression library attaches no meaning to the
- opaque value.
-
- zalloc must return Z_NULL if there is not enough memory for the object.
- If zlib is used in a multi-threaded application, zalloc and zfree must be
- thread safe.
-
- On 16-bit systems, the functions zalloc and zfree must be able to allocate
- exactly 65536 bytes, but will not be required to allocate more than this if
- the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS, pointers
- returned by zalloc for objects of exactly 65536 bytes *must* have their
- offset normalized to zero. The default allocation function provided by this
- library ensures this (see zutil.c). To reduce memory requirements and avoid
- any allocation of 64K objects, at the expense of compression ratio, compile
- the library with -DMAX_WBITS=14 (see zconf.h).
-
- The fields total_in and total_out can be used for statistics or progress
- reports. After compression, total_in holds the total size of the
- uncompressed data and may be saved for use in the decompressor (particularly
- if the decompressor wants to decompress everything in a single step).

-/*
- deflate compresses as much data as possible, and stops when the input
- buffer becomes empty or the output buffer becomes full. It may introduce
- some output latency (reading input without producing any output) except when
- forced to flush.
-
- The detailed semantics are as follows. deflate performs one or both of the
- following actions:
-
- - Compress more input starting at next_in and update next_in and avail_in
- accordingly. If not all input can be processed (because there is not
- enough room in the output buffer), next_in and avail_in are updated and
- processing will resume at this point for the next call of deflate().
-
- - Provide more output starting at next_out and update next_out and avail_out
- accordingly. This action is forced if the parameter flush is non zero.
- Forcing flush frequently degrades the compression ratio, so this parameter
- should be set only when necessary (in interactive applications). Some
- output may be provided even if flush is not set.
-
- Before the call of deflate(), the application should ensure that at least
- one of the actions is possible, by providing more input and/or consuming more
- output, and updating avail_in or avail_out accordingly; avail_out should
- never be zero before the call. The application can consume the compressed
- output when it wants, for example when the output buffer is full (avail_out
- == 0), or after each call of deflate(). If deflate returns Z_OK and with
- zero avail_out, it must be called again after making room in the output
- buffer because there might be more output pending.
-
- Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
- decide how much data to accumulate before producing output, in order to
- maximize compression.
-
- If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
- flushed to the output buffer and the output is aligned on a byte boundary, so
- that the decompressor can get all input data available so far. (In
- particular avail_in is zero after the call if enough output space has been
- provided before the call.) Flushing may degrade compression for some
- compression algorithms and so it should be used only when necessary. This
- completes the current deflate block and follows it with an empty stored block
- that is three bits plus filler bits to the next byte, followed by four bytes
- (00 00 ff ff).
-
- If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
- output buffer, but the output is not aligned to a byte boundary. All of the
- input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
- This completes the current deflate block and follows it with an empty fixed
- codes block that is 10 bits long. This assures that enough bytes are output
- in order for the decompressor to finish the block before the empty fixed code
- block.
-
- If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
- for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
- seven bits of the current block are held to be written as the next byte after
- the next deflate block is completed. In this case, the decompressor may not
- be provided enough bits at this point in order to complete decompression of
- the data provided so far to the compressor. It may need to wait for the next
- block to be emitted. This is for advanced applications that need to control
- the emission of deflate blocks.
-
- If flush is set to Z_FULL_FLUSH, all output is flushed as with
- Z_SYNC_FLUSH, and the compression state is reset so that decompression can
- restart from this point if previous compressed data has been damaged or if
- random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
- compression.
-
- If deflate returns with avail_out == 0, this function must be called again
- with the same value of the flush parameter and more output space (updated
- avail_out), until the flush is complete (deflate returns with non-zero
- avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
- avail_out is greater than six to avoid repeated flush markers due to
- avail_out == 0 on return.
-
- If the parameter flush is set to Z_FINISH, pending input is processed,
- pending output is flushed and deflate returns with Z_STREAM_END if there was
- enough output space; if deflate returns with Z_OK, this function must be
- called again with Z_FINISH and more output space (updated avail_out) but no
- more input data, until it returns with Z_STREAM_END or an error. After
- deflate has returned Z_STREAM_END, the only possible operations on the stream
- are deflateReset or deflateEnd.
-
- Z_FINISH can be used immediately after deflateInit if all the compression
- is to be done in a single step. In this case, avail_out must be at least the
- value returned by deflateBound (see below). Then deflate is guaranteed to
- return Z_STREAM_END. If not enough output space is provided, deflate will
- not return Z_STREAM_END, and it must be called again as described above.
-
- deflate() sets strm->adler to the adler32 checksum of all input read
- so far (that is, total_in bytes).
-
- deflate() may update strm->data_type if it can make a good guess about
- the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
- binary. This field is only for information purposes and does not affect the
- compression algorithm in any manner.
-
- deflate() returns Z_OK if some progress has been made (more input
- processed or more output produced), Z_STREAM_END if all input has been
- consumed and all output has been produced (only when flush is set to
- Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
- if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible

-ZEXTERN int ZEXPORT inflate OF((z_streamp strm, int flush));
-/*
- inflate decompresses as much data as possible, and stops when the input
- buffer becomes empty or the output buffer becomes full. It may introduce
- some output latency (reading input without producing any output) except when
- forced to flush.
-
- The detailed semantics are as follows. inflate performs one or both of the
- following actions:
-
- - Decompress more input starting at next_in and update next_in and avail_in
- accordingly. If not all input can be processed (because there is not
- enough room in the output buffer), next_in is updated and processing will
- resume at this point for the next call of inflate().
-
- - Provide more output starting at next_out and update next_out and avail_out
- accordingly. inflate() provides as much output as possible, until there is
- no more input data or no more space in the output buffer (see below about
- the flush parameter).
-
- Before the call of inflate(), the application should ensure that at least
- one of the actions is possible, by providing more input and/or consuming more
- output, and updating the next_* and avail_* values accordingly. The
- application can consume the uncompressed output when it wants, for example
- when the output buffer is full (avail_out == 0), or after each call of
- inflate(). If inflate returns Z_OK and with zero avail_out, it must be
- called again after making room in the output buffer because there might be
- more output pending.
-
- The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
- Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much
- output as possible to the output buffer. Z_BLOCK requests that inflate()
- stop if and when it gets to the next deflate block boundary. When decoding
- the zlib or gzip format, this will cause inflate() to return immediately
- after the header and before the first block. When doing a raw inflate,
- inflate() will go ahead and process the first block, and will return when it
- gets to the end of that block, or when it runs out of data.
-
- The Z_BLOCK option assists in appending to or combining deflate streams.
- Also to assist in this, on return inflate() will set strm->data_type to the
- number of unused bits in the last byte taken from strm->next_in, plus 64 if
- inflate() is currently decoding the last block in the deflate stream, plus
- 128 if inflate() returned immediately after decoding an end-of-block code or
- decoding the complete header up to just before the first byte of the deflate
- stream. The end-of-block will not be indicated until all of the uncompressed
- data from that block has been written to strm->next_out. The number of
- unused bits may in general be greater than seven, except when bit 7 of
- data_type is set, in which case the number of unused bits will be less than
- eight. data_type is set as noted here every time inflate() returns for all
- flush options, and so can be used to determine the amount of currently
- consumed input in bits.
-
- The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
- end of each deflate block header is reached, before any actual data in that
- block is decoded. This allows the caller to determine the length of the
- deflate block header for later use in random access within a deflate block.
- 256 is added to the value of strm->data_type when inflate() returns
- immediately after reaching the end of the deflate block header.
-
- inflate() should normally be called until it returns Z_STREAM_END or an
- error. However if all decompression is to be performed in a single step (a
- single call of inflate), the parameter flush should be set to Z_FINISH. In
- this case all pending input is processed and all pending output is flushed;
- avail_out must be large enough to hold all of the uncompressed data for the
- operation to complete. (The size of the uncompressed data may have been
- saved by the compressor for this purpose.) The use of Z_FINISH is not
- required to perform an inflation in one step. However it may be used to
- inform inflate that a faster approach can be used for the single inflate()
- call. Z_FINISH also informs inflate to not maintain a sliding window if the
- stream completes, which reduces inflate's memory footprint. If the stream
- does not complete, either because not all of the stream is provided or not
- enough output space is provided, then a sliding window will be allocated and
- inflate() can be called again to continue the operation as if Z_NO_FLUSH had
- been used.
-
- In this implementation, inflate() always flushes as much output as
- possible to the output buffer, and always uses the faster approach on the
- first call. So the effects of the flush parameter in this implementation are
- on the return value of inflate() as noted below, when inflate() returns early
- when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
- memory for a sliding window when Z_FINISH is used.
-
- If a preset dictionary is needed after this call (see inflateSetDictionary
- below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
- chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
- strm->adler to the Adler-32 checksum of all output produced so far (that is,
- total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
- below. At the end of the stream, inflate() checks that its computed adler32
- checksum is equal to that saved by the compressor and returns Z_STREAM_END
- only if the checksum is correct.
-
- inflate() can decompress and check either zlib-wrapped or gzip-wrapped
- deflate data. The header type is detected automatically, if requested when
- initializing with inflateInit2(). Any information contained in the gzip
- header is not retained, so applications that need that information should
- instead use raw inflate, see inflateInit2() below, or inflateBack() and
- perform their own processing of the gzip header and trailer. When processing
- gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
- producted so far. The CRC-32 is checked against the gzip trailer.
-
- inflate() returns Z_OK if some progress has been made (more input processed
- or more output produced), Z_STREAM_END if the end of the compressed data has
- been reached and all uncompressed output has been produced, Z_NEED_DICT if a
- preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
- corrupted (input stream not conforming to the zlib format or incorrect check
- value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
- next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory,
- Z_BUF_ERROR if no progress is possible or if there was not enough room in the
- output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
- inflate() can be called again with more input and more output space to
- continue decompressing. If Z_DATA_ERROR is returned, the application may
- then call inflateSync() to look for a good compression block if a partial
- recovery of the data is desired.

-ZEXTERN int ZEXPORT deflateInit2 OF((z_streamp strm,
- int level,
- int method,
- int windowBits,
- int memLevel,
- int strategy));
-
- This is another version of deflateInit with more compression options. The
- fields next_in, zalloc, zfree and opaque must be initialized before by the
- caller.
-
- The method parameter is the compression method. It must be Z_DEFLATED in
- this version of the library.
-
- The windowBits parameter is the base two logarithm of the window size
- (the size of the history buffer). It should be in the range 8..15 for this
- version of the library. Larger values of this parameter result in better
- compression at the expense of memory usage. The default value is 15 if
- deflateInit is used instead.
-
- windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
- determines the window size. deflate() will then generate raw deflate data
- with no zlib header or trailer, and will not compute an adler32 check value.
-
- windowBits can also be greater than 15 for optional gzip encoding. Add
- 16 to windowBits to write a simple gzip header and trailer around the
- compressed data instead of a zlib wrapper. The gzip header will have no
- file name, no extra data, no comment, no modification time (set to zero), no
- header crc, and the operating system will be set to 255 (unknown). If a
- gzip stream is being written, strm->adler is a crc32 instead of an adler32.
-
- The memLevel parameter specifies how much memory should be allocated
- for the internal compression state. memLevel=1 uses minimum memory but is
- slow and reduces compression ratio; memLevel=9 uses maximum memory for
- optimal speed. The default value is 8. See zconf.h for total memory usage
- as a function of windowBits and memLevel.
-
- The strategy parameter is used to tune the compression algorithm. Use the
- value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
- filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
- string match), or Z_RLE to limit match distances to one (run-length
- encoding). Filtered data consists mostly of small values with a somewhat
- random distribution. In this case, the compression algorithm is tuned to
- compress them better. The effect of Z_FILTERED is to force more Huffman
- coding and less string matching; it is somewhat intermediate between
- Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as
- fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The
- strategy parameter only affects the compression ratio but not the
- correctness of the compressed output even if it is not set appropriately.
- Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
- decoder for special applications.
-
- deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
- memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
- method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
- incompatible with the version assumed by the caller (ZLIB_VERSION). msg is
- set to null if there is no error message. deflateInit2 does not perform any

- Initializes the compression dictionary from the given byte sequence

- deflateReset, and before any call of deflate. When doing raw deflate, this
- function must be called either before any call of deflate, or immediately
- after the completion of a deflate block, i.e. after all input has been
- consumed and all output has been delivered when using any of the flush
- options Z_BLOCK, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, or Z_FULL_FLUSH. The
- compressor and decompressor must use exactly the same dictionary (see
- inflateSetDictionary).
-
- The dictionary should consist of strings (byte sequences) that are likely
- to be encountered later in the data to be compressed, with the most commonly
- used strings preferably put towards the end of the dictionary. Using a
- dictionary is most useful when the data to be compressed is short and can be
- predicted with good accuracy; the data can then be compressed better than
- with the default empty dictionary.
-
- Depending on the size of the compression data structures selected by
- deflateInit or deflateInit2, a part of the dictionary may in effect be
- discarded, for example if the dictionary is larger than the window size
- provided in deflateInit or deflateInit2. Thus the strings most likely to be
- useful should be put at the end of the dictionary, not at the front. In
- addition, the current implementation of deflate will use at most the window
- size minus 262 bytes of the provided dictionary.

-
- The text, time, xflags, and os fields are filled in with the gzip header

- was valid if done is set to one.) If extra is not Z_NULL, then extra_max

-/*
- inflateBack() does a raw inflate with a single call using a call-back
- interface for input and output. This is more efficient than inflate() for
- file i/o applications in that it avoids copying between the output and the
- sliding window by simply making the window itself the output buffer. This
- function trusts the application to not change the output buffer passed by
- the output function, at least until inflateBack() returns.
-
- inflateBackInit() must be called first to allocate the internal state
- and to initialize the state with the user-provided window buffer.
- inflateBack() may then be used multiple times to inflate a complete, raw
- deflate stream with each call. inflateBackEnd() is then called to free the
- allocated state.
-
- A raw deflate stream is one with no zlib or gzip header or trailer.
- This routine would normally be used in a utility that reads zip or gzip
- files and writes out uncompressed files. The utility would decode the
- header and process the trailer on its own, hence this routine expects only
- the raw deflate stream to decompress. This is different from the normal
- behavior of inflate(), which expects either a zlib or gzip header and
- trailer around the deflate stream.
-
- inflateBack() uses two subroutines supplied by the caller that are then
- called by inflateBack() for input and output. inflateBack() calls those
- routines until it reads a complete deflate stream and writes out all of the
- uncompressed data, or until it encounters an error. The function's
- parameters and return types are defined above in the in_func and out_func
- typedefs. inflateBack() will call in(in_desc, &buf) which should return the
- number of bytes of provided input, and a pointer to that input in buf. If
- there is no input available, in() must return zero--buf is ignored in that
- case--and inflateBack() will return a buffer error. inflateBack() will call
- out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out()
- should return zero on success, or non-zero on failure. If out() returns
- non-zero, inflateBack() will return with an error. Neither in() nor out()
- are permitted to change the contents of the window provided to
- inflateBackInit(), which is also the buffer that out() uses to write from.
- The length written by out() will be at most the window size. Any non-zero
- amount of input may be provided by in().
-
- For convenience, inflateBack() can be provided input on the first call by
- setting strm->next_in and strm->avail_in. If that input is exhausted, then
- in() will be called. Therefore strm->next_in must be initialized before
- calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
- immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
- must also be initialized, and then if strm->avail_in is not zero, input will
- initially be taken from strm->next_in[0 .. strm->avail_in - 1].
-
- The in_desc and out_desc parameters of inflateBack() is passed as the
- first parameter of in() and out() respectively when they are called. These
- descriptors can be optionally used to pass any information that the caller-
- supplied in() and out() functions need to do their job.
-
- On return, inflateBack() will set strm->next_in and strm->avail_in to
- pass back any unused input that was provided by the last in() call. The
- return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
- if in() or out() returned an error, Z_DATA_ERROR if there was a format error
- in the deflate stream (in which case strm->msg is set to indicate the nature
- of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
- In the case of Z_BUF_ERROR, an input or output error can be distinguished
- using strm->next_in which will be Z_NULL only if in() returned an error. If
- strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
- non-zero. (in() will always be called before out(), so strm->next_in is
- assured to be defined if out() returns non-zero.) Note that inflateBack()
- cannot return Z_OK.
