NAME
       compare  -  mathematically  and  visually annotate the difference between an image and its
       reconstruction.

SYNOPSIS
       compare input-file input-file [options] output-file

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

       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 number.  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.
