NAME

       diffimg - Calculates intersection between two images

SYNOPSIS

       diffimg image1 image2 [outimage]

DESCRIPTION

       diffimg  generates an image where each pixel is the difference between the corresponding pixel in each of
       the two source images.  Thus, if the source images are the  same  the  resulting  image  will  be  black,
       otherwise it will have regions of non-black where the images differ.

       Currently supports: .png, .gif, .jpg, and .ps by using ghostscript
