NAME
      rlehisto - generate histogram of RLE image.

 SYNOPSIS
      rlehisto [ -b ] [ -c ] [ -t ] [ -h height ] [ -o outfile ] [ infile ]

 DESCRIPTION
      Rlehisto counts the pixel values in an RLE
      file, producing an RLE file graphing
      frequency of occurrence.  The horizontal axis
      runs from pixel value 0 on the left to pixel
      value 255 on the right.  The height indicates
      the number of pixels seen for each pixel
      value.  Histograms are computed independently
      for each channel, scaled identically, and
      then overlaid.  The following options are
      available:

      -b   Don't count the background pixel values
           when scaling the histogram.  This is
           useful if most pixels are colored the
           background color, so that the
           interesting part of the histogram would
           be too small.  This option is ignored if
           -c is specified.

      -c   Output cumulative values instead of
           discrete values.

      -t   Print the totals instead of generating
           the histogram as an RLE file.

      -h   height Scale the output image to the
           specified height.  The default is 256.

      -o outfile
           Direct the output to outfile.
