.SH DESCRIPTION
|
|
The QImageFormatPlugin class provides an abstract base for custom image format plugins.
|
|
.PP
|
|
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.
|
|
.PP
|
|
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.
|
|
.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().
