sbigtopgm - convert an SBIG CCDOPS file to PGM
This program is part of Netpbm(1).
sbigtopgm reads an image file in the native format used by the Santa Barbara Instrument Group (SBIG) astronomical CCD cameras, and produces a PGM image as output. Additional information on SBIG cameras and documentation of the file format is available at the Web site, http://www.sbig.com/ .
sbigtopgm recognizes some variation on the documented SBIG Type 3 format. It allows any capitalization in the header. It ignores all whitespace in the header except newlines. So a header line can end in newline, CRLF, or the bizarre LF-CR actually required by the spec.
There are no command line options defined specifically
for sbigtopgm, but it recognizes the options common to all
programs based on libnetpbm (See
Common Options .)
