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, ]8;;http://www.sbig.com/\http://www.sbig.com/]8;;\ .



OPTIONS
       There  are  no  command line options defined specifically for st4topgm, but it recognizes the
       options common to all programs based on libnetpbm (See ]8;;index.html#commonoptions\ Common Options]8;;\ .)

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.
