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 Bar-
bara Instrument Group (SBIG) ST-4 astronomical CCD cameras, and produces
a PGM image as output. This format is not to be confused with the for-
mat 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

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 com-
parison of the two Netpbms in January 2015. It was the only program
that the Debian version had that the Netpbm version did not (not count-
ing 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 re-
placement in the Netpbm coding style rather than just copy Pryzby's
code, but Bryan endeavoured to keep the same function.
