pnmtofits [-max f] [-min f] [pnmfile]
Reads a portable anymap as input. Produces a FITS (Flexible Image
Transport System) file as output. The resolution of the output file is
either 8 bits/pixel, or 16 bits/pixel, depending on the value of maxval
in the input file. If the input file is a portable bitmap or a porta-
ble graymap, the output file consists of a single plane image (NAXIS =
2). If instead the input file is a portable pixmap, the output file
will consist of a three-plane image (NAXIS = 3, NAXIS3 = 3). A full
description of the FITS format can be found in Astronomy & Astrophysics
Supplement Series 44 (1981), page 363.
Flags -min and -max can be used to set DATAMAX, DATAMIN, BSCALE and
BZERO in the FITS header, but do not cause the data to be rescaled.
FITS uses signed data, and this program outputs unsigned values. If you
run into this problem, you might use "-min 32768".
