NAME
       fstopgm - convert a Usenix FaceSaver(tm)	file into a PGM	image

SYNOPSIS
       fstopgm [fsfile]

DESCRIPTION
       This program is part of Netpbm(1).

       fstopgm	reads  a Usenix	FaceSaver(tm) file as input and	produces a PGM
       image as	output.

       FaceSaver(tm) files sometimes have rectangular pixels.	While  fstopgm
       won't  re-scale	them  into square pixels for you, it will give you the
       precise pamscale	command	that will do the job.  Because of this,	 read-
       ing a FaceSaver(tm) image is a two-step process.	 First you do:

	 fstopgm > /dev/null

       This will tell you whether you need to use pamscale.

       Then use	one of the following pipelines:
	 fstopgm | pnmnorm
	 fstopgm | pamscale -whatever |	pnmnorm

       To go to	PBM, you want something	more like one of these:
	 fstopgm | pamenlarge 3	| pnmnorm | pamditherbw
	 fstopgm | pamenlarge 3	| pamscale <whatever> |	pnmnorm	| pamditherbw

       You  want  to enlarge when going	to a bitmap because otherwise you lose
       information; but	enlarging by more than 3 does not look good.

       FaceSaver is a registered trademark of Metron Computerware Ltd. of Oak-
       land, CA.
