Blt a rectangle of pixels on the graphics screen.
[in] | This | - Protocol instance pointer. |
[in] | BltBuffer | - Buffer containing data to blit into video buffer. This buffer has a size of Width*Height*sizeof(EFI_UGA_PIXEL) |
[in] | BltOperation | - Operation to perform on BlitBuffer and video memory |
[in] | SourceX | - X coordinate of source for the BltBuffer. |
[in] | SourceY | - Y coordinate of source for the BltBuffer. |
[in] | DestinationX | - X coordinate of destination for the BltBuffer. |
[in] | DestinationY | - Y coordinate of destination for the BltBuffer. |
[in] | Width | - Width of rectangle in BltBuffer in pixels. |
[in] | Height | - Hight of rectangle in BltBuffer in pixels. |
[in] | Delta | - OPTIONAL |
EFI_SUCCESS | - The Blt operation completed. |
EFI_INVALID_PARAMETER | - BltOperation is not valid. |
EFI_DEVICE_ERROR | - A hardware error occured writting to the video buffer. |
