◆ ConSplitterGraphicsOutputBlt()

EFI_STATUS EFIAPI ConSplitterGraphicsOutputBlt	(	IN EFI_GRAPHICS_OUTPUT_PROTOCOL *	This,

		IN UINTN	Width,
		IN UINTN	Height,
		IN UINTN Delta	OPTIONAL
	)

The following table defines actions for BltOperations.

EfiBltVideoFill - Write data from the BltBuffer pixel (SourceX, SourceY) directly to every pixel of the video display rectangle (DestinationX, DestinationY) (DestinationX + Width, DestinationY + Height). Only one pixel will be used from the BltBuffer. Delta is NOT used. EfiBltVideoToBltBuffer - Read data from the video display rectangle (SourceX, SourceY) (SourceX + Width, SourceY + Height) and place it in the BltBuffer rectangle (DestinationX, DestinationY ) (DestinationX + Width, DestinationY + Height). If DestinationX or DestinationY is not zero then Delta must be set to the length in bytes of a row in the BltBuffer. EfiBltBufferToVideo - Write data from the BltBuffer rectangle (SourceX, SourceY) (SourceX + Width, SourceY + Height) directly to the video display rectangle (DestinationX, DestinationY) (DestinationX + Width, DestinationY + Height). If SourceX or SourceY is not zero then Delta must be set to the length in bytes of a row in the BltBuffer. EfiBltVideoToVideo - Copy from the video display rectangle (SourceX, SourceY) (SourceX + Width, SourceY + Height) . to the video display rectangle (DestinationX, DestinationY) (DestinationX + Width, DestinationY + Height). The BltBuffer and Delta are not used in this mode.
