DESCRIPTION

16       This program is part of Netpbm(1).
17
18       st4topgm  reads  an  image  file in the native format used by the Santa
19       Barbara Instrument Group (SBIG) ST-4 astronomical CCD cameras, and pro‐
20       duces  a  PGM  image as output.  This format is not to be confused with
21       the format most other SBIG cameras use, for which  you  can  use  sbig‐
22       topgm.
23
24       Additional  information  on  SBIG cameras and documentation of the file
25       format   is   available   at   the   Web   site,   http://www.sbig.com/

HISTORY

35       Bryan  Henderson wrote st4topgm for Sourceforge Netpbm in January 2015.
36       However, there has been another program by the same name for  the  same
37       purpose  since  December 2003, in the Debian version of Netpbm.  It was
38       written by Justin Pryzby <justinpryzby@users.sf.net>.
39
40       Bryan discovered the Debian version when Prophet of the Way did a  com‐
41       parison  of  the  two Netpbms in January 2015.  It was the only program
42       that the Debian version had that the Netpbm version did not (not count‐
43       ing  one  that really didn't belong in any Netpbm), so Bryan decided to
44       add it.  Because it was a small  program,  Bryan  decided  to  write  a
45       replacement  in  the Netpbm coding style rather than just copy Pryzby's
46       code, but Bryan endeavoured to keep the same function.
