<para>
The <filename>pixbufcache</filename> class generates the proper
post-install and post-remove (postinst/postrm) scriptlets for packages
that install pixbuf loaders, which are used with
<filename>gdk-pixbuf</filename>.
These scriptlets call <filename>update_pixbuf_cache</filename>
to add the input method modules to the cache.
Since the cache files are architecture-specific,
<filename>update_pixbuf_cache</filename> is run using QEMU if the
postinst scriptlets need to be run on the build host during image
creation.
</para>
<para>
If the pixbuf loaders modules being installed are in packages other
than the main package, set
<link linkend='var-PIXBUF_PACKAGES'><filename>PIXBUF_PACKAGES</filename></link>
to include the packages containing the modules.

<para>
When a recipe inherits the
<link linkend='ref-classes-pixbufcache'><filename>pixbufcache</filename></link>
class, this variable identifies packages that contain
the pixbuf loaders modules used with
<filename>gdk-pixbuf</filename> that the OpenEmbedded build
system installs.
By default, these modules appear in the main package
(i.e. <filename>${</filename><link linkend='var-PN'><filename>PN</filename></link><filename>}</filename>).
Use this variable if the modules that have the pixbuf
loaders you need appear in a package other than that main
package.
