Hi Lothar,
I found the problem and I'm working on a fix now.  The problem is the tiffs are
16 bit, and the AI model wants 8 bit images.  My code to convert an image from
16 bit to 8 bit had a flaw in it which made the 8 bit image I was passing to
the AI model unreadable.

The fix should be added to digiKam in a day or so.  Once it's added, you will
be able to use your original source Tiffs without a problem.

> Bild009 does not get rotated and Bild026 gets upside down.
The AI isn't 100% accurate, but testing has proven it is well over 95%
accurate.  Sometimes you need to run autorotate on the image again, and
sometimes the AI just can't figure it out.

Cheers,
Mike
