       QImageFormatPlugin - Abstract base for custom image format plugins

       #include <qimageformatplugin.h>

   Public Members
       QImageFormatPlugin ()

       virtual bool installIOHandler ( const QString & format ) = 0

       The QImageFormatPlugin class provides an abstract base for custom image format plugins.

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

       Writing an image 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 Plugins documentation for details.

       See also Plugins.

QImageFormatPlugin::QImageFormatPlugin ()
       Constructs an image format plugin. This is invoked automatically by the Q_EXPORT_PLUGIN

QImageFormatPlugin::~QImageFormatPlugin ()
       Destroys the image format plugin.

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

bool QImageFormatPlugin::installIOHandler ( const QString & format ) [pure virtual]
       Installs a QImageIO image I/O handler for the image format format.

       See also keys().

QStringList QImageFormatPlugin::keys () const [pure virtual]
       Returns the list of image formats this plugin supports.

       See also installIOHandler().
