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.
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.
