Name
       dumppix - dump pixels from a FITS image/cube to stdout

Synopsis
       dumppix [-s rate] [-x col] [-y lin] image.fits

Description
       dumppix  dumps pixel values from a FITS file to stdout in a format that
       can be read by gnuplot to display surfaces for example. As an image may
       contain  too many pixels for useful surface display, a subsampling fac-
       tor may be applied before dumping pixels (see -s option).

       Upon request, dumppix can only output the content of one  line  or  one
       column instead of the whole image (see -x and -y options).

Options
       -s rate
              Applies  a  brutal  subsampling  rate  in  x and y on the pixels
              before dumping.  Default is set to 1 (all pixels). Setting  this
              to 2 would skip 1 pixel out of 2 in each direction, for example.

       -x col Output only the contents of column "col". The  subsampling  rate
              can  also be applied here. The convention for pixel positions is
              FITS: x goes from 1 to NAXIS1.

       -y lin Output only the contents of line "lin". The subsampling rate can
              also  be  applied  here.  The  convention for pixel positions is
              FITS: y goes from 1 to NAXIS2.

Files
       Input files can be images, cubes, or ASCII lists.
