Hi all,
I have the following code. I can correctly print the content of line_smp with boost::geometry::dsv but get strange results when I copy line_smp into a vector and then print the content of the vector.
Any ideas on what I am doing wrong?
bg::model::d2::point_xy p;
while(rs->next()){
bg::set<0>(p, i);
bg::set<1>(p, rs->getDouble("num"));
i++;
line +=p;
}
boost::geometry::simplify(line, line_smp, 0.3);
std::cout<< " original: " << boost::geometry::dsv(line) << std::endl << "simplified: " <<boost::geometry::dsv(line_smp) << std::endl; std::vector<xy> v; v.clear(); std::copy(line_smp.begin(), line_smp.end(), std::back_inserter(v)); stringstream sa, ssa; for(int ia = 0; ia < v.size(); ia++){ sa << bg::get<1>(v[i]); cout << sa; sa.str(""); }
