modify like this is ok ： if ((boost::geometry::comparable_distance(ring[i], ring.back()) - 0.0 < 1e-22)) {

Import relevant test cases from boost geometry test:

WHen I try to compile, correct.hpp is not deducing my custom boost geometry types. ( I register OpenCV points as my point type via BOOST_GEOMETRY_REGISTER_POINT_2D and use polygons that like " boost::geometry::model::polygon<point, true, false>" etc.)

If I explicitly put my types in angle brackets of geometry::correct like geometry::correct<my::point, my::polygon, my::ring, my::polygons>(...), I get compilation errors in correct.hpp where it tries to call internal functions that do not deduce these types correctly.

So I just changed the correct,hpp source file to use my types, but i still get compilation errors. Now I am getting

"self_turn_points.hpp(156,75): error C2039: 'get_envelope_strategy': is not a member of 'boost::geometry::strategies::cartesian'"

I'm wondering if the library code is targeting a different version of boost.geometry?

On implementation in a VS project a compilation error is thrown, any suggestions?

Code

#include <correct.hpp>
#include <boost/assign.hpp>

typedef boost::geometry::model::d2::point_xy<double> point;
typedef boost::geometry::model::polygon<point> polygon;
typedef boost::geometry::model::multi_polygon<polygon> multi_polygon;

void CRegion::CorrectPolyline(PolylineClass myPolyLine)
{
	std::vector<point> points;
	for (int p = 0;p < myPolyLine->GetNumberOfPoints();p++)
	{
		double pnt[3];
		myPolyLine->GetPoint(p, pnt);
		points.push_back(point(pnt[0], pnt[1]));
	}
	// Create a polygon object and assign the points to it.
	polygon aPolygon;
	boost::geometry::assign_points(aPolygon, points);

	multi_polygon input;
	input.push_back(aPolygon);
	multi_polygon result;
	double remove_spike_threshold = 1E-12;
	geometry::correct(input, result, remove_spike_threshold);

	for (auto const& poly : result) {
		std::cout << "Polygon area: " << boost::geometry::area(poly) << std::endl;
	}
}

when i use the hpp in boost 1.72,it compling failed. can you give me a suggestion about it. thank you very much

Hi,
Wouldn't it be interesting to have "correct" inside the main library instead of having to find that it exists ?
The functionnality seems interesting enough to me.

When an inner intersects the outer ring, a by-pass should be generated onto the inner ring from the outer. This will result the outer to "open" when the inner is intersecting through the outer ring.
