11899	boost::geometry::equals doesn't handle open polygons	Bruno Deligny <bruno.deligny@…>	awulkiew	"That doesn't works:

{{{
typedef boost::geometry::model::d2::point_xy<int> P;
boost::geometry::model::polygon<P, false, false> polygon1, polygon2;

boost::geometry::append(polygon1, boost::make_tuple(-18,1));
boost::geometry::append(polygon1, boost::make_tuple(-23,1));
boost::geometry::append(polygon1, boost::make_tuple(-23,-3));
boost::geometry::append(polygon1, boost::make_tuple(-18,-3));

boost::geometry::append(polygon2, boost::make_tuple(-23,1));
boost::geometry::append(polygon2, boost::make_tuple(-23,-3));

boost::geometry::append(polygon2, boost::make_tuple(-18,1));

assert(boost::geometry::equals(polygon1, polygon2) == true);

But this works:
{{{
typedef boost::geometry::model::d2::point_xy<int> P;
boost::geometry::model::polygon<P, false, true> polygon1, polygon2;

boost::geometry::append(polygon1, boost::make_tuple(-18,1));
boost::geometry::append(polygon1, boost::make_tuple(-23,1));
boost::geometry::append(polygon1, boost::make_tuple(-23,-3));
boost::geometry::append(polygon1, boost::make_tuple(-18,-3));
boost::geometry::append(polygon1, boost::make_tuple(-18,1));

boost::geometry::append(polygon2, boost::make_tuple(-23,1));
boost::geometry::append(polygon2, boost::make_tuple(-23,-3));
boost::geometry::append(polygon2, boost::make_tuple(-18,-3));
boost::geometry::append(polygon2, boost::make_tuple(-18,1));
boost::geometry::append(polygon2, boost::make_tuple(-23,1));

assert(boost::geometry::equals(polygon1, polygon2) == true);
