boost::geometry::equals doesn't handle open polygons

Reported by: Bruno Deligny <bruno.deligny@…> Owned by: awulkiew
Milestone: Boost 1.64.0 Component: geometry
Version: Boost 1.60.0 Severity: Problem
Keywords: polygon ring equals Cc:

Description

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,-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);
