Write data from the BltBuffer pixel (SourceX, SourceY)

Read data from the video display rectangle

(SourceX, SourceY) (SourceX + Width, SourceY + Height) and place it in
|
|

|
the BltBuffer rectangle (DestinationX, DestinationY )

Write data from the BltBuffer rectangle

|
|
|
|
video display rectangle (DestinationX, DestinationY)

BltBuffer.

Copy from the video display rectangle

(SourceX, SourceY) (SourceX + Width, SourceY + Height) .
|
|
|
|
to the video display rectangle (DestinationX, DestinationY)
