flipx1
Flip x axis in a fits image
Usage
flipx <input
images>
Overview
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.
Releases
