<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>

    <pre class="prettyprint lang-config">AddHandler imap-file map</pre>


    <p>Note that the following is still supported:</p>

    <pre class="prettyprint lang-config">AddType application/x-httpd-imap map</pre>


    <p>However, we are trying to phase out "magic MIME types" so we
    are deprecating this method.</p>

<div class="section">
<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>&lt;base&gt;</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>&lt;base href="<var>value</var>"&gt;
      </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 be 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 be 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>
        &lt;a href="http://example.com/"&gt;<var>Menu text</var>&lt;/a&gt;
      </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>
        &lt;a href="http://example.com/"&gt;http://example.com&lt;/a&gt;
      </code></p></div>

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

    <p>The <code class="directive">ImapDefault</code> directive sets the default
    <code>default</code> used in the imagemap files. Its value is
    overridden by a <code>default</code> directive within the
    imagemap file. If not present, the <code>default</code> action
    is <code>nocontent</code>, which means that a <code>204 No
    Content</code> is sent to the client. In this case, the client
    should continue to display the original page.</p>

      <dt><code>none</code></dt>
      <dd>If ImapMenu is <code>none</code>, no menu is generated,
      and the <code>default</code> action is performed.</dd>

      <dt><code>formatted</code></dt>
      <dd>A <code>formatted</code> menu is the simplest menu.
      Comments in the imagemap file are ignored. A level one header
      is printed, then an hrule, then the links each on a separate
      line. The menu has a consistent, plain look close to that of
      a directory listing.</dd>

      <dt><code>semiformatted</code></dt>
      <dd>In the <code>semiformatted</code> menu, comments are
      printed where they occur in the imagemap file. Blank lines
      are turned into HTML breaks. No header or hrule is printed,
      but otherwise the menu is the same as a
      <code>formatted</code> menu.</dd>

      <dt><code>unformatted</code></dt>
      <dd>Comments are printed, blank lines are ignored. Nothing is
      printed that does not appear in the imagemap file. All breaks
      and headers must be included as comments in the imagemap
      file. This gives you the most flexibility over the appearance
      of your menus, but requires you to treat your map files as
      HTML instead of plaintext.</dd>
