Hugin Align and Stitch

[der_fotograf]

I have never reported this »bug« because I didn't know where to search.

Just out of curiosity I would like to know if it would be possible to correct the output.

I am using 16/48 bit TIFF images for panoramas, either converted with Nikon NX-D or RPP (Raw Photo Processor).

When I generate control points or perform the final stitching, I get this message:

I am not a programmer, but I think it would be easy to fix the last 4 warning lines in the process window.

Anybody has any idea? Could it be a setting in the »Preferences«?

The warning is issued when reading the input file. They come from libtiff (the lib hugin is using for reading TIF file). Libtif is the reference implementation for the TIF files. So this warning means that your TIF files does not fully comply to the TIF spec.

So if you get rid of the warning you need to fix it in the program which generated the TIF files (Hugin does never write to input files.)
