XmImage structure - XmImage Image definition.
A XmImage structure is returned by the XmImageCreate and XmImageCreateFromInfo convenience routines.See XmImageInfo(3X) for more information about the dispose field in the XmImageFrame structure.
The pixmap and clip fields in the XmImage structure can be used directly in calls to XCopyArea(3X).
