and what about the opposite ? stay in discrete coordinate in the code and add a normalized message ? in that way the conversion is done only once (when the ROI is set in normalized coord) and not each time we set the data (for pix_set) maybe i'm going wrong...
i'd rather not. the way it is now, [pix_roi] is independent of the actual pixes. i very much like it that way.
one could provide helper-functions to easily convert a given ROI/pix to absolute coordinates on the C++ layer, if you care about the programming overhead. the computational overhead is small enough.
