NAME

       fitstopnm - convert a FITS file into a portable anymap

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
       produce an ASCII portable anymap.

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