Packit	78deda	`DESCRIPTION`
Packit	78deda
Packit	78deda	`This program is part of Netpbm.`
Packit	78deda
Packit	78deda	`fstopgm reads a Usenix FaceSaver(tm) file as input and`
Packit	78deda	`produces a PGM image as output.`
Packit	78deda
Packit	78deda	`FaceSaver(tm) files sometimes have rectangular pixels. While`
Packit	78deda	`fstopgm won't re-scale them into square pixels for you, it will`
Packit	78deda	`give you the precise pamscale command that will do the job.`
Packit	78deda	`Because of this, reading a FaceSaver(tm) image is a two-step process.`
Packit	78deda	`First you do:`
Packit	78deda
Packit	78deda
Packit	78deda	`fstopgm > /dev/null`
Packit	78deda
Packit	78deda
Packit	78deda	`This will tell you whether you need to use pamscale.`
Packit	78deda
Packit	78deda	`Then use one of the following pipelines:`
Packit	78deda
Packit	78deda	`fstopgm \| pnmnorm`
Packit	78deda	`fstopgm \| pamscale -whatever \| pnmnorm`
Packit	78deda
Packit	78deda
Packit	78deda	`To go to PBM, you want something more like one of these:`
Packit	78deda
Packit	78deda	`fstopgm \| pamenlarge 3 \| pnmnorm \| pamditherbw`
Packit	78deda	`fstopgm \| pamenlarge 3 \| pamscale <whatever> \| pnmnorm \| pamditherbw`
Packit	78deda
Packit	78deda
Packit	78deda	`You want to enlarge when going to a bitmap because otherwise you lose`
Packit	78deda	`information; but enlarging by more than 3 does not look good.`
Packit	78deda
Packit	78deda	`FaceSaver is a registered trademark of Metron Computerware Ltd. of`
Packit	78deda	`Oakland, CA.`
