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.

Returns:
