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
