Hi PaQ, ooops sorry yeah I see now that last script won't work unless your image width:height happens to match the same 3:2 aspect ratio of 35mm film.

In order for this to work on any size viewport, the width to height aspect ratio needs to be known by the script, so the previous one will be the one to use.

By the way, the reason why MoI controls the angle by the innermost square is so that there isn't a really big difference in the general working seen area of the view depending on the window's current size. For example if you drag the main MoI window to different shapes, you get stuff like this:






If the display is controlled by horizontal angle only, then that tall viewport would have its contents look kind of all shrunken down, if it used the same horizontal angle as what was used for the initial wide viewport.
