Hello,

i am trying to get one intersection point between line polygon or line line,

i tried

typedef model::d2::point_xy<double> point;
typedef model::ring< point > ring;
typedef model::polygon< point > polygon;
typedef model::linestring< point > linestring;
boost::geometry::read_wkt(
        "POLYGON((0 0,1 0, 1 1,0 1))", green);
linestring ls;
boost::geometry::read_wkt("LINESTRING(0.5 -1,0.5 0.5)", ls);
std::vector<point> intersections;
boost::geometry::intersection(green, blue, intersections);

but it is not working. I only want the point which is on the border.
Anyone has an idea for that ?

thank you for help. I am really new on boost.
