Hi, I just modified a test program taken from AGG's examples to test the polygon clipping capability of following libraries. *Boost.Polygon *GPC *Clipper
Here are some observations: 1) The proccesing speed (fastest to slowest): Clipper > GPC > Boost.Polygon 2) With "xor", although the results seems the same, they have different countours numbers (Clipper the least). 3) Boost.Polygon has a strange behavior that it sometimes produces erroneous vertical lines within the polygons. In this example, with "or" operation you'll see that.
I put the test files here: http://tinyurl.com/2axoqxc
Anyone who wants to compile it will also need AGG and Clipper on your computer.
Cannot download your files, says they are unavailable (although I see them fine...).
