| <h3>Summary</h3> |
| |
| <p>This module processes <code>.map</code> files, thereby |
| replacing the functionality of the <code>imagemap</code> CGI |
| program. Any directory or document type configured to use the |
| handler <code>imap-file</code> (using either |
| <code class="directive"><a href="../mod/mod_mime.html#addhandler">AddHandler</a></code> or |
| <code class="directive"><a href="../mod/core.html#sethandler">SetHandler</a></code>) |
| will be processed by this module.</p> |
| |
| <p>The following directive will activate files ending with |
| <code>.map</code> as imagemap files:</p> |
| |
| <div class="example"><p><code>AddHandler imap-file map</code></p></div> |
| |
| <p>Note that the following is still supported:</p> |
| |
| <div class="example"><p><code>AddType application/x-httpd-imap map</code></p></div> |
| |
| <p>However, we are trying to phase out "magic MIME types" so we |
| are deprecating this method.</p> |

| <h2><a name="features" id="features">New Features</a></h2> |
| |
| <p>The imagemap module adds some new features that were not |
| possible with previously distributed imagemap programs.</p> |
| |
| <ul> |
| <li>URL references relative to the Referer: information.</li> |
| |
| <li>Default <code><base></code> assignment through a new map |
| directive <code>base</code>.</li> |
| |
| <li>No need for <code>imagemap.conf</code> file.</li> |
| |
| <li>Point references.</li> |
| |
| <li>Configurable generation of imagemap menus.</li> |
| </ul> |
| </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> |
| <div class="section"> |
| <h2><a name="imapfile" id="imapfile">Imagemap File</a></h2> |
| |
| <p>The lines in the imagemap files can have one of several |
| formats:</p> |
| |
| <div class="example"><p><code> |
| directive value [<var>x</var>,<var>y</var> ...]<br /> |
| directive value "<var>Menu text</var>" [<var>x</var>,<var>y</var> |
| ...]<br /> |
| directive value <var>x</var>,<var>y</var> ... "<var>Menu text</var>" |
| </code></p></div> |
| |
| <p>The directive is one of <code>base</code>, |
| <code>default</code>, <code>poly</code>, <code>circle</code>, |
| <code>rect</code>, or <code>point</code>. The value is an |
| absolute or relative URL, or one of the special values listed |
| below. The coordinates are <code><var>x</var>,<var>y</var></code> |
| pairs separated by whitespace. The quoted text is used as the text of |
| the link if a imagemap menu is generated. Lines beginning with '#' are |
| comments.</p> |
| |
| <h3><a name="imapfile.directives" id="imapfile.directives">Imagemap File Directives</a></h3> |
| <p>There are six directives allowed in the imagemap file. The |
| directives can come in any order, but are processed in the |
| order they are found in the imagemap file.</p> |
| |
| <dl> |
| <dt><code>base</code> Directive</dt> |
| |
| <dd><p>Has the effect of <code><base href="<var>value</var>"> |
| </code>. The non-absolute URLs of the map-file are taken relative |
| to this value. The <code>base</code> directive overrides |
| <code class="directive"><a href="#imapbase">ImapBase</a></code> as set in a |
| <code>.htaccess</code> file or in the server configuration files. |
| In the absence of an <code class="directive">ImapBase</code> configuration |
| directive, <code>base</code> defaults to |
| <code>http://server_name/</code>.</p> |
| <p><code>base_uri</code> is synonymous with <code>base</code>. |
| Note that a trailing slash on the URL is significant.</p></dd> |
| |
| <dt><code>default</code> Directive</dt> |
| |
| <dd>The action taken if the coordinates given do not fit any |
| of the <code>poly</code>, <code>circle</code> or |
| <code>rect</code> directives, and there are no |
| <code>point</code> directives. Defaults to <code>nocontent</code> |
| in the absence of an <code class="directive"><a href="#imapdefault">ImapDefault</a></code> configuration setting, causing a status |
| code of <code>204 No Content</code> to be returned. The client |
| should keep the same page displayed.</dd> |
| |
| <dt><code>poly</code> Directive</dt> |
| |
| <dd>Takes three to one-hundred points, and is obeyed if the |
| user selected coordinates fall within the polygon defined by |
| these points.</dd> |
| |
| <dt><code>circle</code></dt> |
| |
| <dd>Takes the center coordinates of a circle and a point on |
| the circle. Is obeyed if the user selected point is with the |
| circle.</dd> |
| |
| <dt><code>rect</code> Directive</dt> |
| |
| <dd>Takes the coordinates of two opposing corners of a |
| rectangle. Obeyed if the point selected is within this |
| rectangle.</dd> |
| |
| <dt><code>point</code> Directive</dt> |
| |
| <dd>Takes a single point. The point directive closest to the |
| user selected point is obeyed if no other directives are |
| satisfied. Note that <code>default</code> will not be |
| followed if a <code>point</code> directive is present and |
| valid coordinates are given.</dd> |
| </dl> |
| |
| |
| <h3><a name="imapfile.values" id="imapfile.values">Values</a></h3> |
| |
| <p>The values for each of the directives can any of the following:</p> |
| |
| <dl> |
| <dt>a URL</dt> |
| |
| <dd><p>The URL can be relative or absolute URL. Relative URLs |
| can contain '..' syntax and will be resolved relative to the |
| <code>base</code> value.</p> |
| <p><code>base</code> itself will not resolved according to the |
| current value. A statement <code>base mailto:</code> will |
| work properly, though.</p></dd> |
| |
| <dt><code>map</code></dt> |
| |
| <dd>Equivalent to the URL of the imagemap file itself. No |
| coordinates are sent with this, so a menu will be generated |
| unless <code class="directive"><a href="#imapmenu">ImapMenu</a></code> is set to |
| <code>none</code>.</dd> |
| |
| <dt><code>menu</code></dt> |
| <dd>Synonymous with <code>map</code>.</dd> |
| |
| <dt><code>referer</code></dt> |
| |
| <dd>Equivalent to the URL of the referring document. Defaults |
| to <code>http://servername/</code> if no <code>Referer:</code> |
| header was present.</dd> |
| |
| <dt><code>nocontent</code></dt> |
| |
| <dd>Sends a status code of <code>204 No Content</code>, |
| telling the client to keep the same page displayed. Valid for |
| all but <code>base</code>.</dd> |
| |
| <dt><code>error</code></dt> |
| |
| <dd>Fails with a <code>500 Server Error</code>. Valid for all |
| but <code>base</code>, but sort of silly for anything but |
| <code>default</code>.</dd> |
| </dl> |
| |
| |
| <h3><a name="imapfile.coords" id="imapfile.coords">Coordinates</a></h3> |
| |
| <dl> |
| <dt><code>0,0 200,200</code></dt> |
| |
| <dd>A coordinate consists of an <var>x</var> and a <var>y</var> |
| value separated by a comma. The coordinates are separated |
| from each other by whitespace. To accommodate the way Lynx |
| handles imagemaps, should a user select the coordinate |
| <code>0,0</code>, it is as if no coordinate had been |
| selected.</dd> |
| </dl> |
| |
| |
| |
| <h3><a name="imapfile.quotedtext" id="imapfile.quotedtext">Quoted Text</a></h3> |
| |
| <dl> |
| <dt><code>"<var>Menu Text</var>"</code></dt> |
| |
| <dd><p>After the value or after the coordinates, the line |
| optionally may contain text within double quotes. This string |
| is used as the text for the link if a menu is |
| generated:</p> |
| |
| <div class="example"><p><code> |
| <a href="http://foo.com/"><var>Menu text</var></a> |
| </code></p></div> |
| |
| <p>If no quoted text is present, the name of the link will be |
| used as the text:</p> |

| <div class="example"><p><code> |
| <a href="http://foo.com/">http://foo.com</a> |
| </code></p></div> |

| <p>If you want to use double quotes within this text, you have to |
| write them as <code>&quot;</code>.</p></dd> |
