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.
|
|
|

|
|
(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.
