[ptx] Bug report: Hugin and 16 bit images, and fulla

Strange. Did you use some of the "auto" functions?

Strange. Will try to reproduce after my wedding.

Hmm, maybe it is possible to generate a PSD file with layer offsets from
the tiff files generated by nona with the CROP option? (Or write a macro to load
the files into separate layers?)
This should lead to massive savings during post processing.

Unfortunately there is no tutorial yet. A very concise description is in the nona.txt
file in the doc/ directory. There has also been some discussion about in on this list.

ciao
