In the next example, the “cropped” image from Figure A-2 is mapped to a new
destination space on the display device.
Figure A-4.
Cropped Source mapped to Destination
In this case, the WDR value would be defined as:
300 500 450 300
Using WDR, you can take a portion of the source image and (without resizing
it) can place it anywhere on the display device. By changing the destination
size parameters (450,300 in the above example), to 1280 x 1024, we could
expand this cropped image to fill the display device. In this case, the WDR
value would be defined as:
0 0 1280 1024

ASPECT RATIO
As you learned in the previous sections, the source rectangle parameter selects
any desired rectangular portion of an input image. This image can then be
displayed (mapped) in a destination rectangle — in an identical or different
configuration of size and position. Please note:
• The destination rectangle can be set to any shape and any size on the
output monitor — up to the full size of the output display screen.
Note This action is effectively zooming into a section of the
source image.
