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 programs 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 <justinpryzby@users.sf.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.
