An IDLgrBuffer object is an in-memory, off-screen destination object. Object trees can be drawn to instances of the IDLgrBuffer object and the resulting image can be retrieved from the buffer using the Read() method. The off-screen representation avoids dithering artifacts by providing a full-resolution buffer for objects using either the RGB or Color Index color models.
Note: Objects or subclasses of this type can not be saved or restored.
