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 AUTHOR diffimg was written by John Ellson <ellson@research.att.com> This manual page was written by David Claughton <dave@eclectic- dave.com>, for the Debian project (but may be used by others).
