description
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 portable 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.
options
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.
bugs
FITS uses
signed data, and this program outputs unsigned values. If
you run into this problem, you might use "-min
32768".
