Examples
The resulting image is shown in the figure below. The overlays have moved in this image
and that the overall image size is now larger than before.
34.3.5 Downscale VGA to WQVGA (480x272) to fill screen
In this example, a VGA image will be downscaled to fix the extents of a 480x272 WQVGA
display. This means that the aspect ratio of the resulting image will not match that of the
source image, therefore the scaling factors in the horizontal and vertical directions will
differ from each other.
