NAME

   fitstopnm - convert a FITS file into a PNM image

SYNOPSIS

   fitstopnm  [-image N] [-scanmax] [-printmax] [-min f] [-max f]
[FITSfile]

   All options may be abbreviated to their shortest  unique  pre-
fix.

DESCRIPTION

   This program is part of Netpbm.

   fitstopnm  reads a FITS file as input and produces a PPM image
if the FITS
   file consists of 3 image planes (NAXIS = 3 and NAXIS3 = 3), or
a PGM image
   if the FITS file consists of 2 image planes (NAXIS = 2), or if
you specify
   the -image option. The results may need to be flipped top  for
bottom; if so,
   just pipe the output through pamflip -tb.

OPTIONS

   The	-image	option is for FITS files with three axes. The as-
sumption is that
   the third axis is for multiple images, and  this  option  lets
you select which
   one you want.

   You	can use options -min and -max to override the min and max
values as read
   from the FITS header or the image data if no DATAMIN and DATA-
MAX keywords
   are found.

   You	can  use the -scanmax option to force the program to scan
the data even
   when DATAMIN and DATAMAX are found in the header. If you spec-
ify -printmax,
   the program will just print the min and max values and quit.

   The program tells you what kind of PNM image it is writing.
