\class QPictureFormatPlugin
\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(),
loadPicture(), savePicture(), and installIOHandler(), and
exporting the class with the Q_EXPORT_PLUGIN2() macro.
\sa {How to Create Qt Plugins}
*/
/*!
\fn QStringList QPictureFormatPlugin::keys() const
Returns the list of picture formats this plugin supports.
\sa installIOHandler()
*/
/*!
\fn bool QPictureFormatPlugin::installIOHandler(const QString &format)
Installs a QPictureIO picture I/O handler for the picture format \a
format.

/*!
Constructs an picture format plugin with the given \a parent.
This is invoked automatically by the Q_EXPORT_PLUGIN2() macro.

Destroys the picture format plugin.
You never have to call this explicitly. Qt destroys a plugin
automatically when it is no longer used.
