C# Class Mapsui.Geometries.Polygon

A Polygon is a planar Surface, defined by 1 exterior boundary and 0 or more interior boundaries. Each interior boundary defines a hole in the Polygon.

Vertices of rings defining holes in polygons are in the opposite direction of the exterior ring.

Public Methods

Method	Description
Clone ( ) : Polygon	Return a copy of this geometry
Contains ( System.Point point ) : bool
Distance ( System.Point point ) : double	Returns the shortest distance between any two points in the two geometries as calculated in the spatial reference system of this Geometry.
Equals ( Polygon p ) : bool	Determines if this Polygon and the specified Polygon object has the same values
GetBoundingBox ( ) : BoundingBox	Returns the bounding box of the object
GetHashCode ( ) : int	Serves as a hash function for a particular type. GetHashCode is suitable for use in hashing algorithms and data structures like a hash table.
InteriorRing ( int n ) : LinearRing	Returns the Nth interior ring for this Polygon as a LineString This method is supplied as part of the OpenGIS Simple Features Specification
IsEmpty ( ) : bool	If true, then this Geometry represents the empty point set, Ø, for the coordinate space.
Polygon ( ) : System	Instatiates a polygon
Polygon ( LinearRing exteriorRing ) : System	Instatiates a polygon based on one extorier ring.
Polygon ( LinearRing exteriorRing, IList interiorRings ) : System	Instatiates a polygon based on one extorier ring and a collection of interior rings.
