NAME
flipx - Flip x axis in a FITS image
SYNOPSIS
flipx <input images>
DESCRIPTION
This is an example use of the qfits library. This program expects a
list of FITS file names in input. For each input file, it will flip the
image contained in the main data section in the X direction, i.e. pixel
(i,j) is swapped with pixel (lx-i, j).
The pixel loading mechanism is independent from endian-ness of the
local host or FITS pixel type. This program offers a good overview of
how to use qfits for pixel-level operations.
OPTIONS
None.
FILES
Input files shall all comply with FITS format.
BUGS
Notice that this program does not support cubes or image extensions,
but could be easily extended to support that case.
