- Description
The NLVBCKeyCaps property defines flags indicating the available driver specific color key capabilities for nonlocal to local video memory blits in a way similar to TDDCaps::CKeyCaps.
Only the blit related flags of this property should be used.
The described effect applies when the flag is set.
