SYNOPSIS

DESCRIPTION

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