NAME
       st4topgm - convert an SBIG ST-4 camera file to PGM

SYNOPSIS
       st4topgm

       [st4file]

DESCRIPTION
       This program is part of Netpbm(1).

       st4topgm reads an image file in the native format used by the Santa Barbara Instrument Group (SBIG) ST-4 astronomical
       CCD  cameras,  and produces a PGM image as output.  This format is not to be confused with the format most other SBIG
       cameras use, for which you can use sbigtopgm.

       Additional information on SBIG cameras  and  documentation  of  the  file  format  is  available	 at  the  Web  site,
       http://www.sbig.com/ .

OPTIONS
       There are no command line options defined specifically for st4topgm, but it recognizes the options common to all pro‐
       grams based on libnetpbm (See  Common Options .)

HISTORY
       Bryan  Henderson	 wrote	st4topgm for Sourceforge Netpbm in January 2015.  However, there has been another program by
       the same name for the same purpose since December 2003, in the Debian version of Netpbm.	 It was	 written  by  Justin
       Pryzby .

       Bryan  discovered the Debian version when Prophet of the Way did a comparison of the two Netpbms in January 2015.  It
       was the only program that the Debian version had that the Netpbm version did not (not counting one that really didn't
       belong in any Netpbm), so Bryan decided to add it.  Because it was a small program, Bryan decided to write a replace‐
       ment in the Netpbm coding style rather than just copy Pryzby's code, but Bryan endeavoured to keep the same function.
