Is there a way to load a section of a snapshot, without getting the full image first?

And an updated version. Everything except help and live-preview should work now.
I also implemented the set function like the image-acquisition package, to give back the range and step size for the setting.
I will not be trying to get live preview to work. Next step is integrating it in the image-acquisition package. With a little lick I can re-use their preview stuff.

thanks for the code.
I have a Matlab script from a colleague which (if i remeber it right) is able to get live images from USB cams.
Sadly i can’t get a Matlab license for me there.
If it can help you i can ask him on Monday and send you the file.
I am busy implementing webcam support on Windows.
I based it on the interface described by the webcam package of matlab
It is currently in a very early and rough stage. No help yet, very dirty code, etc. I only managed to get it working today, but it can already obtain images. Also Brightness, backlight etc, can be set. No resolution control at the moment.
Once I have everything working, I might try and integrate it in the img-acq package.
