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".
