- Routine Description:\r
- The following table defines actions for BltOperations:\r
- EfiBltVideoFill - Write data from the BltBuffer pixel (SourceX, SourceY) \r
- directly to every pixel of the video display rectangle \r
- (DestinationX, DestinationY) (DestinationX + Width, DestinationY + Height). \r
- Only one pixel will be used from the BltBuffer. Delta is NOT used.\r
- EfiBltVideoToBltBuffer - Read data from the video display rectangle \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
- EfiBltBufferToVideo - 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
- EfiBltVideoToVideo - Copy from the video display rectangle (SourceX, SourceY)\r
- (SourceX + Width, SourceY + Height) .to the video display rectangle \r
- (DestinationX, DestinationY) (DestinationX + Width, DestinationY + Height). \r
- The BltBuffer and Delta are not used in this mode.\r
-\r
- Arguments:\r
- This - Protocol instance pointer.\r
- BltBuffer - Buffer containing data to blit into video buffer. This \r
- buffer has a size of Width*Height*sizeof(EFI_GRAPHICS_OUTPUT_BLT_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
- Height - Hight of rectangle in BltBuffer in pixels.\r
- Delta -\r
- \r
- Returns:\r
- EFI_SUCCESS - The Blt operation completed.\r
- EFI_INVALID_PARAMETER - BltOperation is not valid.\r
- EFI_DEVICE_ERROR - A hardware error occured writting to the video \r
- buffer.\r
