NAME
      rlescale - produce gray scale images.

 SYNOPSIS
      rlescale [ -c ] [ -n nsteps ] [ -o outfile ] [ xsize ] [ ysize ]

 DESCRIPTION
      Rlescale produces an RLE image containing a
      (more-or-less) standard gray scale image.
      Along the bottom are 8 colored patches (in
      the standard primary and secondary colors).
      Above these are a sequences of
      logarithmically scaled gray patches.  By
      default, a 16 step scale is produced.  The
      size of the output file (default 512 by 480)
      can be set with the xsize and ysize
      arguments.

 OPTIONS
      -c   Produce red, green, blue, and gray
           scales.

      -n nsteps
           Specify the number of steps to be
           produced.
