NAME
fstopgm - convert a Usenix FaceSaver(tm) file into a portable graymap
SYNOPSIS
fstopgm [fsfile]
DESCRIPTION
Reads a Usenix FaceSaver(tm) file as input. Produces a portable graymap 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 pnmscale command that will do the
job. Because of this, reading a FaceSaver(tm) image is a two-step process. First you do:
fstopgm > /dev/null
This will tell you whether you need to use pnmscale. Then use one of the following
pipelines:
fstopgm | pgmnorm
fstopgm | pnmscale -whatever | pgmnorm
To go to PBM, you want something more like one of these:
fstopgm | pnmenlarge 3 | pgmnorm | pgmtopbm
fstopgm | pnmenlarge 3 | pnmscale <whatever> | pgmnorm | pgmtopbm
You want to enlarge when going to a bitmap because otherwise you lose information; but
enlarging by more than 3 does not look good.
