-ofile
              Output file (default stdout)

       -eext FITS extension number (default 0)

       -pplane
              Image plane number (default 0)

       -mmargin
              Number of pixels to avoid at the image edges (default 0)

       -O     Do ordinal transform (default: map 25-95 percentile)

       -Lpercentile
              Set percentile that becomes black (default 25)

       -Hpercentile
              Set percentile that becomes white (default 95)

       -I     Invert black-on-white image

       -Xmax Set the input value that will become white

       -Nmin Set the input value that will become black

       -x     Set max to the observed maximum value

       -n     Set min to the observed minimum value

       -r     Same as -x-n: set min and max to observed data range.

       -s     Write 16-bit output

       -v     Verbose

       -M     Compute & print median value
