ok, thanks, now it seems to be a little bit clearer. but how can that help me?
My first thought after reading your explanation was, that I simply subtract the values calculated from fromLatLngToPixel(ne, 13) and fromLatLngToPixel(ne, 12). but that don't worked. The result is still to big. because if I would know, how many pixel are now "more" on the map that would solve my problem.
