DESCRIPTION

       This program is part of Netpbm(1).

       This  program  is  obsolete  since  Netpbm  10.23  (July  2004).    Use
       pamditherbw(1)todowhatthisprogram used to do.

       pgmtopbm  never  was  the simple converter it appeared to be.  It was a
       dithering program.  Unfortunately, it didn’t do the dithering  properly
       because  it treated the PGM input samples as if they were directly pro-
       portional to light intensity, but they are actually gamma-adjusted.

       pamditherbw is backward compatible with pgmtopbm except  that  it  does
       the correct gamma adjustments.
