OVERVIEW


       The compare program is a member of the ImageMagick(1) suite  of  tools.
       Use  it  to mathematically and visually annotate the difference between
       an image and its reconstruction.

         -verbose             print detailed information about the image
         -virtual-pixel method
                              virtual pixel access method

       Miscellaneous Options:
         -debug events        display copious debugging information
         -help                print program options
         -log format          format of debugging information
         -list type           print a list of supported option arguments
         -version             print version information

       By default, the image format of `file' is determined by its magic  num-
       ber.   To  specify a particular image format, precede the filename with
       an image format name and a colon (i.e. ps:image) or specify  the  image
       type as the filename suffix (i.e. image.ps).  Specify 'file' as '-' for
       standard input or output.
