QImageFormatPlugin - Abstract base for custom image format plugins
SYNOPSIS
#include <qimageformatplugin.h>
Public Members
QImageFormatPlugin ()
~QImageFormatPlugin ()
virtual QStringList keys () const = 0
virtual bool installIOHandler ( const QString & format ) = 0
DESCRIPTION
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.
MEMBER FUNCTION DOCUMENTATIONQImageFormatPlugin::QImageFormatPlugin ()
Constructs an image format plugin. This is invoked automatically by the
Q_EXPORT_PLUGIN macro.
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().
