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".
