- 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.
