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".
