Some simple image processing capabilities are present in the Forms
Library image support. All the image processing routines take an image
as a parameter and process it in place. If appropriate, only the
subimage specified by (image->subx, image->suby) and
(image->subw, image->subw) is affected (note these are
different fields from those for subimage displaying). The subimage
fields are best set via user interaction, perhaps by having a rubber
band that the user can drag to set the size.
In the following, each routine will be briefly explained.
