NAME

   pnmtofits - convert a portable anymap into FITS format

SYNOPSIS

   pnmtofits [-max f] [-min f] [pnmfile]

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".
