Possibly, though it might be possible in the general case to use the Python
Imaging Library to manipulate channels in an image.

The simplest solution might be to call the rgbSwapped() method on the QImage
holding the data to obtain an image with the red and blue channels swapped.
This is, of course, done in C++ by the Qt library itself.
