The TQImageFormatPlugin class provides an abstract base for custom image format plugins.
< p >
< p > 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.
< p > Writing an image format plugin is achieved by subclassing this
base class, reimplementing the pure virtual functions < a href = "#keys" > keys< / a > () and
< a href = "#installIOHandler" > installIOHandler< / a > (), and exporting the class with the
TQ_EXPORT_PLUGIN macro. See the < a href = "plugins-howto.html" > Plugins
documentation< / a > for details.
< p > See also < a href = "plugins.html" > Plugins< / a > .
< hr > < h2 > Member Function Documentation< / h2 >
< h3 class = fn > < a name = "TQImageFormatPlugin" > < / a > TQImageFormatPlugin::TQImageFormatPlugin ()
< / h3 >
Constructs an image format plugin. This is invoked automatically
by the TQ_EXPORT_PLUGIN macro.
< h3 class = fn > < a name = "~TQImageFormatPlugin" > < / a > TQImageFormatPlugin::~TQImageFormatPlugin ()
< / h3 >
Destroys the image format plugin.
< p > You never have to call this explicitly. TQt destroys a plugin
automatically when it is no longer used.
