there is no need to convert the color for displaying, since the display hardware (grphic card, screen and probably the windowing system as well) can't show more than 8bits per channel anyhow.
You will have to norm your values to 255 per channel in order to display them.
As I said in my previous post, we need more colors thatn 8bit can support. The graphics hardware we use is capable of supporting 16 bit colors, as is X11 (I'm talking Linux here). Our app is drawing wave forms among many other things that colors are needed for. If Qt can support colors greater than 8bit, than I have a serious show stopper for using Qt to do the graphics rendering.
