Type specifying a pointer to a function to perform an UGA Blt operation.
The following table defines actions for BltOperations:
<B>EfiUgaVideoFill</B> - 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.
<B>EfiUgaVideoToBltBuffer</B> - 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.
<B>EfiUgaBltBufferToVideo</B> - 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.
<B>EfiUgaVideoToVideo</B> - 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[in] This - Protocol instance pointer.
@param[in] BltBuffer - Buffer containing data to blit into video buffer. This
buffer has a size of Width*Height*sizeof(EFI_UGA_PIXEL)
@param[in] BltOperation - Operation to perform on BlitBuffer and video memory
@param[in] SourceX - X coordinate of source for the BltBuffer.
@param[in] SourceY - Y coordinate of source for the BltBuffer.
@param[in] DestinationX - X coordinate of destination for the BltBuffer.
@param[in] DestinationY - Y coordinate of destination for the BltBuffer.
@param[in] Width - Width of rectangle in BltBuffer in pixels.
@param[in] Height - Height of rectangle in BltBuffer in pixels.
@param[in] Delta - OPTIONAL
@retval EFI_SUCCESS - The Blt operation completed.
@retval EFI_INVALID_PARAMETER - BltOperation is not valid.
@retval EFI_DEVICE_ERROR - A hardware error occurred writing to the video buffer.
