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 for-
       mat  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/ <http://www.sbig.com/> .

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 <justinpryzby AT users.net>.

       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
       replacement  in  the  Netpbm  coding  style rather than just copy Pryzby's code, but Bryan
       endeavoured to keep the same function.
