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
