fitstopnm


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

DESCRIPTION
       Reads a FITS file as input.  Produces a portable  pixmap  if  the  FITS
       file  consists of 3 image planes (NAXIS = 3 and NAXIS3 = 3), a portable
       graymap if the FITS file consists of 2 image planes  (NAXIS  =  2),  or
       whenever  the  -image  flag  is  specified.  The results may need to be
       flipped top for bottom; if so, just pipe  the  output  through  pnmflip
       -tb.

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

       Flags  -min  and -max can be used to override the min and max values as
       read from the FITS header or the image data if no DATAMIN  and  DATAMAX
       keywords  are found.  Flag -scanmax can be used to force the program to
       scan the data even when DATAMIN and DATAMAX are found in the header. If
       -printmax  is  specified,  the  program will just print the min and max
       values and quit.  Flag -noraw can be used to force the program to  pro-
       duce an ASCII portable anymap.

       The program will tell what kind of anymap is writing.  All flags can be
       abbreviated to their shortest unique prefix.
