NAME

6       flipx - Flip x axis in a FITS image
7

SYNOPSIS

9       flipx <input images>
10

DESCRIPTION

12       This  is  an  example  use of the qfits library. This program expects a
13       list of FITS file names in input. For each input file, it will flip the
14       image contained in the main data section in the X direction, i.e. pixel
15       (i,j) is swapped with pixel (lx-i, j).
16
17       The pixel loading mechanism is  independent  from  endian-ness  of  the
18       local  host  or FITS pixel type. This program offers a good overview of
19       how to use qfits for pixel-level operations.

BUGS

28       Notice that this program does not support cubes  or  image  extensions,
29       but could be easily extended to support that case.
