Summary

This class encapsulates double-precision polygons.

Constructors

PolygonD(IEnumerable<PointD> vertices)	Initializes a polygon from a given list of vertices.
PolygonD(params PointD[] vertices)	Initializes a polygon from a given array of vertices.

Instance methods

double	Area()	Determines the area of the current PolygonD.
BoundingBoxD	BoundingBox()	Returns the bounding box of this polygon.
PointD	Centroid()	Calculates the centroid of this polygon.
bool	ContainsPoint(Point point)	Determines whether the current PolygonD contains the specified point.
bool	ContainsPoint(PointD point)	Determines whether the current PolygonD contains the specified point. If the point lies exactly on one of the polygon edges, it is considered to be contained in the polygon.
bool	IsConvex()	Determines whether this polygon is convex or concave. Throws if all vertices lie on a straight line, or if there are 2 or fewer vertices.
IEnumerable<EdgeD>	ToEdges()	Returns an array containing all the edges of this polygon.
PointF[]	ToPointFArray()	Converts the current PolygonD to an array of PointF structures. Note that this conversion loses precision.

Instance properties

IEnumerable<EdgeD>	Edges	Enumerates the edges of this polygon in vertex order. The enumerable is "live" and reflects any changes to PolygonD.Vertices immediately.
List<PointD>	Vertices	Returns a list of vertices of the polygon.
