See the Plugins documentation for details. +.PP +See also Plugins. +.SH MEMBER FUNCTION DOCUMENTATION +.SH "QImageFormatPlugin::QImageFormatPlugin ()" +Constructs an image format plugin. This is invoked automatically by the Q_EXPORT_PLUGIN macro. +.SH "QImageFormatPlugin::~QImageFormatPlugin ()" +Destroys the image format plugin. +.PP +You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used. +.SH "bool QImageFormatPlugin::installIOHandler ( const QString & format )\fC [pure virtual]\fR" +Installs a QImageIO image I/O handler for the image format \fIformat\fR. +.PP +See also keys(). +.SH "QStringList QImageFormatPlugin::keys () const\fC [pure virtual]\fR" +Returns the list of image formats this plugin supports. +.PP +See also installIOHandler(). + +.SH "SEE ALSO" +.BR http://doc.trolltech.com/ntqimageformatplugin.html +.BR http://www.trolltech.com/faq/tech.html +.SH COPYRIGHT +Copyright 1992-2007 Trolltech ASA, http://www.trolltech.com.
