Programming with the UMSImageWindowMClass Object

Ultimedia Services Version 2 for AIX: Programmer's Guide and Reference

Programming with the UMSImageWindowMClass Object

The UMSImageWindowMClass metaclass is an Ultimedia Services Version 2 feature and does not apply to Ultimedia Services Version 1.2.1.

UMSImageWindowMClass is the metaclass for the UMSImageWindow object. It provides a way to create an instance of an UMSImageWindow object. If an image format is given to the metaclass, it can look to see if hardware acceleration is available and create an instance of the appropriate hardware-specific UMSImageWindow object.

Because the interface requires X11-specific structure definitions and information unavailable to SOM, this object cannot be used with DSOM.

UMSImageWindowMClass Methods

UMSImageWindowMClass includes the following methods:

make_from_display	Creates an instance of the UMSImageWindow class suitable for the specified display.
make_from_display_and_src	Creates an instance of the UMSImageWindow class suitable for both the display and the list of image formats.
make_from_display_src_and_window	Creates an instance of the UMSImageWindow class suitable for the display, the window, and the list of image formats.
