Syntax

public class Contour

Constructors

Contour(IEnumerable<Vertex>)

Initializes a new instance of the Contour class.

Declaration

public Contour(IEnumerable<Vertex> points)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<Vertex>	points	The points that make up the contour.

Contour(IEnumerable<Vertex>, Int32)

Initializes a new instance of the Contour class.

Declaration

public Contour(IEnumerable<Vertex> points, int marker)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<Vertex>	points	The points that make up the contour.
System.Int32	marker	Contour marker.

Contour(IEnumerable<Vertex>, Int32, Boolean)

Initializes a new instance of the Contour class.

Declaration

public Contour(IEnumerable<Vertex> points, int marker, bool convex)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<Vertex>	points	The points that make up the contour.
System.Int32	marker	Contour marker.
System.Boolean	convex	The hole is convex.

Properties

Points

Gets or sets the list of points making up the contour.

Declaration

public List<Vertex> Points { get; set; }

Property Value

Type	Description
System.Collections.Generic.List<Vertex>

Methods

FindInteriorPoint(Int32, Double)

Try to find a point inside the contour.

Declaration

public Point FindInteriorPoint(int limit = 5, double eps = 2E-05)

Parameters

Type	Name	Description
System.Int32	limit	The number of iterations on each segment (default = 5).
System.Double	eps	Threshold for co-linear points (default = 2e-5).

Returns

Type	Description
Point	Point inside the contour

Remarks

For each corner (index i) of the contour, the 3 points with indices i-1, i and i+1 are considered and a search on the line through the corner vertex is started (either on the bisecting line, or, if CounterClockwise(Point, Point, Point) is less than eps, on the perpendicular line. A given number of points will be tested (limit), while the distance to the contour boundary will be reduced in each iteration (with a factor 1 / 2^i, i = 1 ... limit).

Exceptions

Type	Condition
System.Exception	Throws if no point could be found.

GetSegments()

Declaration

public List<ISegment> GetSegments()

Returns

Type	Description
System.Collections.Generic.List<ISegment>
