- (DestinationX, DestinationY) \r
- (DestinationX + Width, DestinationY + Height).\r
- Only one pixel will be used from the BltBuffer. Delta is NOT used.\r

- (SourceX, SourceY) (SourceX + Width, SourceY + Height) and place it in \r
- the BltBuffer rectangle (DestinationX, DestinationY ) \r
- (DestinationX + Width, DestinationY + Height). If DestinationX or \r
- DestinationY is not zero then Delta must be set to the length in bytes \r
- of a row in the BltBuffer.\r
- EfiUgaBltBufferToVideo - Write data from the BltBuffer rectangle \r
- (SourceX, SourceY) (SourceX + Width, SourceY + Height) directly to the \r
- video display rectangle (DestinationX, DestinationY) \r
- (DestinationX + Width, DestinationY + Height). If SourceX or SourceY is \r
- not zero then Delta must be set to the length in bytes of a row in the \r
- BltBuffer.\r
- EfiUgaVideoToVideo - Copy from the video display rectangle \r
- (SourceX, SourceY) (SourceX + Width, SourceY + Height) .\r
- to the video display rectangle (DestinationX, DestinationY) \r
- (DestinationX + Width, DestinationY + Height). \r

- BltBuffer - Buffer containing data to blit into video buffer. This \r
- buffer has a size of Width*Height*sizeof(EFI_UGA_PIXEL)\r
- BltOperation - Operation to perform on BlitBuffer and video memory\r
- SourceX - X coordinate of source for the BltBuffer.\r
- SourceY - Y coordinate of source for the BltBuffer.\r
- DestinationX - X coordinate of destination for the BltBuffer.\r
- DestinationY - Y coordinate of destination for the BltBuffer.\r
- Width - Width of rectangle in BltBuffer in pixels.\r

- Returns:\r
- EFI_SUCCESS - The Blt operation completed.\r
