Hotspotting a Gigapixel Image

  • 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!

  • Hi,

    you want to keep the line with of polygonal hotspot always the same, right?

    that should already work - just set/use the borderwidth setting of the polygonal hotspot - this width will be always the same, regardless of the zoom...

    best regards,
    Klaus
