  background.


1.3 - Monday 02 July 2007
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  option class ezcImageSaveOptions supports setting a quality indicator for
  JPEG and a compression indicator for PNG images.
- Implemented feature #9564: Watermark (and perhaps other filters) should
  allow image placements from opposite corners. Crop filters support negative
  offsets now, too.


1.2 - Monday 18 December 2006

  Cache, ConsoleTools, ImageAnalysis, ImageConversion, PersistentObject,
  PersistentObjectDatabaseSchemaTiein.
- Fixed issue #9520: ImageConversion test fails.
- Fixed issue #9521: Watermark tests needs some tuning.

- Fixed issue #9819: Let all components deal with the ezcBaseAutoloadException
  properly.


1.2beta1 - Monday 20 November 2006
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Added feature #9236: Added two new filters for adding watermarks to images.
- Fixed issue #8892: Handler / Converter destruction should remove all temp
  files.
- Fixed issue #9012: Problems with open_basedir.
- Fixed issue #9013: SVG not detected in
  ezcImageImagemagickBaseHandler::determineTypes().

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Fixed bug #8958: GD crop filter calculates width and height incorrect.
- Fixed bug #8959: GD and ImageMagick crop filters behave differently. The GD
  driver now behaves like the ImageMagick driver and reduces the crop
  dimensions, if they are larger than the source image dimensions.


1.1.1 - Monday 28 August 2006
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Fixed bug #8712: The x and y parameters for cropping where handled as 
  coordinates and not as offsets.
- Refactored to use new ezcBaseStruct and properties approach.


1.1 - Monday 12 June 2006
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- No changes at all.


1.1rc1 - Monday 29 May 2006
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- No changes at all.


1.1beta1 - Wednesday 19 April 2006
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Added checks for file names that could cause potential security issues.
  File names containing one of ', " or $ will be rejected to load/save with an
  ezcImageFileNameInvalidException. (See 
  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=345238).
- Refactored internal filter handling to make ezcImageHandler classes
  publically available.
- Fixed bug #8137: ImageConversion - ezcImageTransformation fails on
  processing Multiple images in 1 request.


1.0.1 - Thursday 23 February 2006
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Fixed unreported bug: ezcImageTransformation::setFilters() threw old style
  exceptions on an invalid filter class. Now throws the correct
  ezcBaseSettingValueException.
- Added checks for file names that could cause potential security issues. File
  names containing one of the three characters ' " or $ will be rejected to
  load/save with an ezcImageFileNameInvalidException. (See
  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=345238).


1.0 - Monday 30 January 2006
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Fixed unreported bug: ezcImageTransformation will cause an error, if no
  filters are submitted, but only a MIME type conversion is set.
- Fixed unreported bug: ImageAnalysis and ImageConversion used different
  MIME types for PSD files.
- Fixed unreported bug: Missing sanity checks for file existance and
  reabability in ezcImageTransformation::transform().


1.0rc1 - Monday 16 January 2006
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Added more MIME types to ezcImageImagemagickHandler to be able to
  transform more formats.
- Added option for ezcImageImagemagickHandler to allow the explicit setting of
  ImageMagick's "convert" binary.

- Changed exception behavior. All errors will now throw a different exception
  class.
- Changed OS detection of ezcImageImagemagickHandler to better detect Windows
  versions.
- Changed behavior of ezcImageGeometryFilters::scale() to its
  original purpose. The scale() filter now allows scaling of images to fit
  into a certain rectengular box. The former behavior is still available
  throug the scaleExact() filter.
- Changed execution of ImageMagick binary from exec() to proc_open(). This
  avoids nasty error output on the console if something fails. Errors from
  STDERR are now caught and used in the thrown exception for analysis.

- Fixed bug #7640: "createTransformation aspect ratio scaling". 
  The ImageMagick driver now does correct scaling, maintaining aspect ratio.
- Fixed unreported bug, that $name attribute in ezcImageMethodcallHandler is
  private, but accessed by it's derived classes for error reporting.
- Fixed unreported bug in crop filter code of ezcImageImagemagickHandler, that
  caused the crop to always start at the coordinates 0, 0.


1.0beta2 - Friday 23 December 2005
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Added struct for ezcImageConverter settings: ezcImageConverterSettings.
- Added new method getIdentifier() to handler classes which returns
  a lowercase version of the name. The convert class uses this instead of
  lowercasing the name manually.
- Added ezcImageFilter struct to keep the filter name and
  options. This replaces the associative arrays and separate parameters used
  throughout the various classes (mostly ezcImageTransformation).

- Changed settings handling in ezcImageConverter to new struct
  ezcImageConverterSettings.
- Changed ezcImageHandler objects to get their $name and $identifier in
  their constructor.
- Changed ezcImageHandlers not to automagically find the correct class name for
  a filter. Instead the ezcImageFilters object is now created by the specific 
  ezcImageHandler class.

- Changed functions to properties:

  * ezcImageHandler::getName() to property 'name'.
  * ezcImageHandler::getIdentifier() to property 'identifier'.

- Changed class names:

  * ezcImageHandlerGd to ezcImageGdHandler.
  * ezcImageHandlerShell to ezcImageShellHandler.
  * ezcImageFiltersGd to ezcImageGdFilters.
  * ezcImageFiltersShell to ezcImageShellFilters.
  * ezcImageFiltersInterfaceEffect to ezcImageEffectFilters.
  * ezcImageFiltersInterfaceGeomtry to ezcImageGeometryFilters.
  * ezcImageFiltersInterfaceColorspace to ezcImageColorspaceFilters.
  * ezcImageShellHandler to ezcImageImagemagickHandler.
  * ezcImageShellFilters to ezcImageImagemagickFilters.

- Changed function names:

  * ezcImageHandler::listFilters() to getFilterNames().

- Changed ezcImageTransformation::transform() to throw a catch-all exception
  instead of all inherited ones. The catch-all exception stores the source
  exception in it's 'parent' property.
- Changed visibility of filter handling classes to private.
  The code for the filter handling needs to more work before
  becoming public. Any references to the filter classes from public
  classes are also removed. This marks the GD and Imagemagick handlers as
  private.
- Changed ezcImageHandler::listFilters() to use the getFilters() method on
  the filter object to get filter list.

- Changed the way on how handlers can be referenced. The class names which are
  passed in ezcImageConverterSettings are now stored in the
  ezcImageHandlerSettings class:

  * Added a reference name setting which are used by the converter
    and handler. This allows the developer to reference the handler
    with a simple name.
  * Add a settings array which can be used by the handler as configuration.

- Removed 'identifier' from ezcImageHandler and uses class name of handler
  for lookup in ezcImageConverter::applyFilter().
- Removed generation from class names out of values in
  ezcImageConverterSettings.  Instead they should now pass the full class name
  to the converter. This removes the need to prefix custom made handler
  classes with ezcImageHandler.
- Removed all the special code from the abstract class ezcImageHandler and
  added them to ezcImageMethodcallHandler. The main handler class is now much
  cleaner and exposes less special functions and properties to the public.

  * Updated GD and ImageMagick handlers to extends the new class.

- Fixed createTransformation() to return the transformation object.
