       pnmtofits - convert a portable anymap into FITS format

       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".
