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
