Hi Dane Ok after some playing around I could get it working as well - it was again the QMAKE_CXXFLAGS +=' -ansi' that was missing. Don't know why it did not work on my first attempt.
Anyway - the viewer now shows the same output like my program: http://img12.imageshack.us/img12/4949/viewertest.jpg With nik2img it works perfectly: http://img813.imageshack.us/img813/2969/test2.png nik2img.py test2.xml test2.png -v Step: 1 // --> Nik2img starting...
