This page describes, in Unix manual page style, an addition to the
image toolkit which converts images written in the native file format
used by the Santa Barbara Instrument Group's
astronomical CCD cameras into a portable graymap suitable for processing
with other PBMplus utilities.
sbigtopgm - convert an SBIG CCDOPS file into a portable graymap
sbigtopgm [ sbigfile ]
Reads an an image file in the native format used by the Santa Barbara
Instrument Group (SBIG) astronomical CCD cameras, and
produces a portable graymap as output. Additional information
on SBIG cameras and documentation of the file format is available
at the Web site http://www.sbig.com/.
All SBIG CCD cameras have 14 or 16 bits per pixel; PBMPLUS must be
compiled with BIGGRAYS defined in pbmplus.h or this
program will fail. When BIGGRAYS is defined, raw format output
is disabled for pgm and ppm files; the resulting ASCII
files are much larger and take far more time to read and write.
