Hey,i'm trying to use bg::intersection to find the intersection between a line segment and a polygon.in some cases it works, but in others it doesn't.there should be an intersection between these two geometries but i get nothing in the result.anyone knows of any issues regarding this type of intersections?this is the test code i ran:bgPolygonType testPol;boost::geometry::read_wkt("POLYGON((1012 1621, 1013 1621, 1013 1622, 1012 1622, 1012 1621))", testPol);typedef bg::model::d2::point_xy<double, boost::geometry::cs::cartesian> point_t;typedef bg::model::linestring<point_t> linestring_t;linestring_t ls;bg::append(ls, point_t(1011.4, 1621.64));bg::append(ls, point_t(1013.6, 1623.68));std::vector<point_t> res;bg::intersection(testPol, ls, res);thanksSergei
