    \class QPictureFormatPlugin qpictureformatplugin.h
    \brief The QPictureFormatPlugin class provides an abstract base for custom picture format plugins.

    \ingroup plugins

    The picture format plugin is a simple plugin interface that makes
    it easy to create custom picture formats that can be used
    transparently by applications.

    Writing an picture format plugin is achieved by subclassing this
    base class, reimplementing the pure virtual functions keys() and
    installIOHandler(), and exporting the class with the
    Q_EXPORT_PLUGIN macro.  See the \link plugins-howto.html Plugins
    documentation\endlink for details.
