I apologize in advance if this question has been asked but after days of research I'm at a standstill.
I'm trying to draw routes on a gigapixel image that when zoomed in they are proportionate to what is being viewed. As you zoom in on the line or the hotspot these get smaller in size. I've managed to hotspot a gigapixel image but when I zoom in the hotspot just gets bigger.
If anyone could point me n the right direction, or tell me the correct terms to use when searching it would be greatly appreciated. Thanks in advance!
