Such effect can be applied and resulting image is black, too.

I cannot accept any bugs report from 0.9.0 because code is under development. If you read the TODO file, you can see that sharpen algorithm need to be updated to support 16 bits image. Actually, the code is broken in the tool. This is why you have a black hole instead the image. I close this file. I will just restored the algorithm to work only why 8 bits images! If you know image filter algorithms, you can help me to finalize this job (:=))))... Gilles Caulier
