Hallo Florian, > Hiding the underlying utilities and the shell window is on my list, but > I have yet to find a way to interact with the commandline tools like > dispcal programmatically (and cross-platform). My remark was not intended to take away value from dispcalGUI because the user still needs to interact with dispcal inside a shell window, in the background. I think I was under the wrong impression. I don't think you need to spend time hiding Argyll's commande line interface completely as you probably have lot's of other, more interesting priorities. So, please, unless this is really easy to do, cross-platform, which I don't suspect is that easy, leave dispcalGUI the way it is. Besides, it's fine that the user sees the progress of dispcal in a shell window. Are there options in dispcal that will launch dispcal on its own, without requiring any user intervention? Like a completely automated way of going about calibrating and profiling? I think you could add some mention of the fact that dispcalGUI is not designed to completely hide or encapsulate the functionality of dispcal, that some interaction with the dispcal is still required inside a shell. This being said, Florian, do you also have a similar GUI for the printer or scanner part of Argyll? > Yes, it generally benefits from a larger sample count.

That it may be adequate for slow instruments, like the filter-based colorimeters, but faster instruments will benefit from the 512 higher sample count. BTW, I still to experiment with the options in the Extra menu. Like calibration and profile verification. Last but not least, can the Spyder3 be used, today, with dispcal?
