<div class="refsect1">
<a name="gdk-pixbuf-Module-Interface.description"></a><h2>Description</h2>
<p>If GdkPixBuf has been compiled with GModule support, it can be extended by
modules which can load (and perhaps also save) new image and animation
formats. Each loadable module must export a
<a class="link" href="gdk-pixbuf-Module-Interface.html#GdkPixbufModuleFillInfoFunc" title="GdkPixbufModuleFillInfoFunc ()"><span class="type">GdkPixbufModuleFillInfoFunc</span></a> function named <code class="literal">fill_info</code> and
a <a class="link" href="gdk-pixbuf-Module-Interface.html#GdkPixbufModuleFillVtableFunc" title="GdkPixbufModuleFillVtableFunc ()"><span class="type">GdkPixbufModuleFillVtableFunc</span></a> function named
<code class="literal">fill_vtable</code>.</p>
<p>In order to make format-checking work before actually loading the modules
(which may require dlopening image libraries), modules export their
signatures (and other information) via the <code class="literal">fill_info</code> function. An
external utility, gdk-pixbuf-query-loaders, uses this to create a text
file containing a list of all available loaders and their signatures.
This file is then read at runtime by GdkPixBuf to obtain the list of
available loaders and their signatures. </p>
<p>Modules may only implement a subset of the functionality available via
<a class="link" href="gdk-pixbuf-Module-Interface.html#GdkPixbufModule" title="struct GdkPixbufModule"><span class="type">GdkPixbufModule</span></a>. If a particular functionality is not implemented, the
<code class="literal">fill_vtable</code> function will simply not set the corresponding
function pointers of the <a class="link" href="gdk-pixbuf-Module-Interface.html#GdkPixbufModule" title="struct GdkPixbufModule"><span class="type">GdkPixbufModule</span></a> structure. If a module supports
incremental loading (i.e. provides <span class="type">begin_load</span>, <span class="type">stop_load</span> and
<span class="type">load_increment</span>), it doesn't have to implement <span class="type">load</span>, since GdkPixBuf can
supply a generic <span class="type">load</span> implementation wrapping the incremental loading. </p>
<p>Installing a module is a two-step process:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>copy the module file(s) to the loader directory (normally
<code class="literal">$libdir/gdk-pixbuf-2.0/$version/loaders</code>, unless overridden by the
environment variable <code class="literal">GDK_PIXBUF_MODULEDIR</code>) </p></li>
<li class="listitem"><p>call gdk-pixbuf-query-loaders to update the module file (normally
<code class="literal">$libdir/gdk-pixbuf-2.0/$version/loaders.cache</code>, unless overridden by the
environment variable <code class="literal">GDK_PIXBUF_MODULE_FILE</code>)</p></li>
</ul></div>
<p>The GdkPixBuf interfaces needed for implementing modules are contained in
<code class="literal">gdk-pixbuf-io.h</code> (and <code class="literal">gdk-pixbuf-animation.h</code> if the module supports
animations). They are not covered by the same stability guarantees as the
regular GdkPixBuf API. To underline this fact, they are protected by
<code class="literal">#ifdef GDK_PIXBUF_ENABLE_BACKEND</code>.</p>

<p>The signature of a module is a set of prefixes. Prefixes are encoded as
pairs of ordinary strings, where the second string, called the mask, if
not <a href="../glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>, must be of the same length as the first one and may contain
' ', '!', 'x', 'z', and 'n' to indicate bytes that must be matched,
not matched, "don't-care"-bytes, zeros and non-zeros.
Each prefix has an associated integer that describes the relevance of
the prefix, with 0 meaning a mismatch and 100 a "perfect match".</p>
<p>Starting with gdk-pixbuf 2.8, the first byte of the mask may be '*',
indicating an unanchored pattern that matches not only at the beginning,
but also in the middle. Versions prior to 2.8 will interpret the '*'
like an 'x'. </p>
<p>The signature of a module is stored as an array of

where the <em class="parameter"><code>prefix</code></em>

GdkPixbufModulePattern *signature[] = {

The example matches e.g. "auud\0" with relevance 100, and "blau" with
relevance 90.</informalexample></p>
