Damn. I forgot the attachments....

That might react badly to your > reimplementation of calculateViewingTransform. Yes, recenterOnResize was enabled. But if I set recenterOnResize=false, nothing gets scaled at all! (And I don't know why. It seems I really have to view through some implementation details in JSVGCanvas.) >> 2.

Actually, I thought what I am doing would't be that tricky, because my current implementation is far from complex. Well, it is now attached. Maybe you see my mistake. :-) Regards Marco
