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