Thanks for the output, Pablo.

The beauty of PTstitcher is tries hard to interpolates between values,
and avoid harsh changes in gradients. It uses the array more as a
mapping function than a lookup table.. I think Helmut had in mind the
implementation of 16bit images, but only completed 8bit support.
