DIFFIMG(1) General Commands Manual DIFFIMG(1)
diffimg - Calculates intersection between two images
diffimg image1 image2 [outimage]
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
