NAME
      rlenoise - Add random noise to an image

 SYNOPSIS
      rlenoise [ -n amount ] [ -o outfile ] [ infile ]

 DESCRIPTION
      Rlenoise adds uniform random noise to an
      image.  The peak-to-peak amplitude of the
      noise can be specified with the -n flag, the
      default value is 4.  This program may be
      useful for trying to deal with quantization
      in an output device, if you are able to trade
      spatial resolution for color resolution, and
      you don't have a good characterization of the
      quantization function.

 OPTIONS
      infile
           The input will be read from this file,
           otherwise, input will be taken from
           stdin.

      -o outfile
           If specified, output will be written to
           this file, otherwise it will go to
           stdout.
