Is Roll over possible with Synfig

I am working on making an interactive coverage map. Specifically, I want to have a map that allows a user to scroll over a particular country and have a text box pop up with information detailing the type of coverage my company offers for that country. Is this possible to do in Synfig?

I assume that you’ll want to put it in a website, right? In that case SVG+Javascript might be more appropiate:
carto.net/papers/svg/samples … ects.shtml

Any SVG shape can be made interactive following the same scheme as that example. You’ll just need to create the map in SVG format with each country as a separate shape.
