Hello, I didn't find how to cross-link a path. Is it possible in Gimp and how to do it. I need it as i am using the path tool to create something like a map of countries with their borders. Thanks !
What do you mean by cross-link? Edit in one app and seamlessly use it in another?
I think the OP means a three way or four way control point in a path. Not Possible. Make complete separate boundaries for each country, overlapping where necessary.
One can download country boundaries in .SVG format :

Just change the name of the country in the link to download another.
Get them in gimp by clicking the right mouse button and choose 'Import Path' ( .SVG file)
