There seems to be a slight problem with setting image or channel depth. Using Q16, setting the depth to 8 bit, you will have a 16 bit file. Doesn't matter with better previews / image processing programs. With Win systems the display for TIFF files is a kind of psychedelic art. This took me hours until I did check with PhotoShop. Besides: even if it works with RGB and PNG files, this consumes resources. Have a look on file size. Only way out: change to Q8. IMHO there is no way to run Q8 and Q16 simultaneously. The above said concerns also setImageDepth.
