Routine Description:
The following table defines actions for BltOperations:
EfiUgaVideoFill - 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.
EfiUgaVideoToBltBuffer - 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.
EfiUgaBltBufferToVideo - 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.
EfiUgaVideoToVideo - 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.
Arguments:
This - Protocol instance pointer.
BltBuffer - Buffer containing data to blit into video buffer. This
buffer has a size of Width*Height*sizeof(EFI_UGA_PIXEL)
BltOperation - Operation to perform on BlitBuffer and video memory
SourceX - X coordinate of source for the BltBuffer.
SourceY - Y coordinate of source for the BltBuffer.
DestinationX - X coordinate of destination for the BltBuffer.
DestinationY - Y coordinate of destination for the BltBuffer.
Width - Width of rectangle in BltBuffer in pixels.
Height - Hight of rectangle in BltBuffer in pixels.
Delta -
Returns:
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.
