NAME
       pgmtopbm - convert a PGM image to PBM

SYNOPSIS
       pgmtopbm

       [-floyd | -fs | -threshold | -hilbert | -dither8 | -d8 | -cluster3 | -c3 | -cluster4 | -c4
       | -cluster8 | -c8]

       [-value val]

       [-clump size]

       [pgmfile]

DESCRIPTION
       This program is part of Netpbm(1)

       This program is obsolete since Netpbm 10.23 (July 2004).  Use pamditherbw(1)
	to do what this program 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 sam-
       ples as if they were directly proportional to  light  intensity,  but  they  are  actually
       gamma-adjusted.

       pamditherbw is backward compatible with pgmtopbm except that it

       o      does the correct gamma adjustments.

       o      produces	PAM output instead of PBM.  (Modern Netpbm programs that accept PBM input
	      also accept PAM input, but if you need  actual  PBM,  you  can  use  pamtopbm  with
	      pamditherbw).

	      So use the manual for pamditherbw for pgmtopbm, except ignore anything that says it
	      was added after Netpbm Release 10.23 and ignore any options that are not	shown  in
	      the synopsis above.

       If you just want to convert a PGM image with maxval 1 to PBM, use pamtopnm(1)
