Methods

FillWithRandomPositions<TVertex>(Double, Double, Double, Double, IEnumerable<TVertex>, IDictionary<TVertex, Point>, Random)

Initializes the positions of the vertices. Assigns a random position inside the 'bounding box' to the vertices without positions. It does NOT modify the position of the other vertices. Bounding box: x coordinates: double.Epsilon - width y coordinates: double.Epsilon - height

Declaration

public static void FillWithRandomPositions<TVertex>(double width, double height, double translateX, double translateY, IEnumerable<TVertex> vertices, IDictionary<TVertex, Point> verticesPositions, Random random)

Parameters

Type	Name	Description
System.Double	width	Width of the bounding box.
System.Double	height	Height of the bounding box.
System.Double	translateX	Translates the generated x coordinate.
System.Double	translateY	Translates the generated y coordinate.
System.Collections.Generic.IEnumerable<TVertex>	vertices	Vertices to fill positions.
System.Collections.Generic.IDictionary<TVertex, Point>	verticesPositions	Initial vertices positions.
System.Random	random	Random number generator to use.

Type Parameters

Name	Description
TVertex	Vertex type.

GetClippingPoint(Size, Point, Point)

Computes the clipping point based on clipping rectangle size and two points (center and p)).

Declaration

public static Point GetClippingPoint(Size size, Point center, Point p)

Parameters

Type	Name	Description
Size	size	Clipping zone size.
Point	center	Center of the clipping zone.
Point	p	Point to clip.

Returns

Type	Description
Point	Clipping point.

IsSameDirection(Vector, Vector)

Checks if both Vectors have the same direction.

Declaration

public static bool IsSameDirection(Vector a, Vector b)

Parameters

Type	Name	Description
Vector	a	First vector.
Vector	b	Second vector.

Returns

Type	Description
System.Boolean	True if both vectors have the same direction, false otherwise.

NormalizePositions<TVertex>(IDictionary<TVertex, Point>)

Normalizes the given verticesPositions.

Declaration

public static void NormalizePositions<TVertex>(IDictionary<TVertex, Point> verticesPositions)

Parameters

Type	Name	Description
System.Collections.Generic.IDictionary<TVertex, Point>	verticesPositions	Vertices positions to normalize.

Type Parameters

Name	Description
TVertex	Vertex type.
