Each input’s destination rectangle is defined in terms of the display device’s screen space coordinates, rather than the input picture’s coordinates. Each destination rectangle represents the source rectangle mapped to a specific size and position on the display.

In the example below, the display monitor is 1280 x 1024. The full size source rectangle from Figure A-1 is mapped to a destination rectangle, starting at coordinates (300,500), with a horizontal width of 600 pixels and a vertical height of 250 lines.

Figure A-3.Full Size Source mapped to Destination

The Window Destination Rectangle (WDR) command defines the size and position of the destination rectangle for the image displayed on the output channel.

Thus, to map the full size picture from Figure A-1 (WSR 0 0 639, 479) to a destination rectangle, the WDR would be defined as:

300 500 600 250

Note that in this example the original image size (the source) is 640 x 480 pixels but the size of the destination is 600 x 250. The resulting image (destination image) is smaller than the original and also has a different aspect ratio. Also the image is no longer located at the top left (origin) of the output display, but is moved more towards the center.
