fstopgm(1) General Commands Manual fstopgm(1) 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, 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 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.
