Syntax

public static class ConnectionUtilities

Methods

AllPoints(IConnection)

Returns all the points of this connection, i.e. the start and end points together with the intermediate connection points.

Declaration

public static IList<Point> AllPoints(this IConnection connection)

Parameters

IConnection connection The connection.

Returns

System.Collections.Generic.IList<Point>

CalculateMiddlePointOfLine(Tuple<Point, Point>, IList<Point>)

Calculates the middle point of line.

Declaration

public static Point CalculateMiddlePointOfLine(Tuple<Point, Point> connectionEnds, IList<Point> connectionPoints)

Parameters

System.Tuple<Point, Point> connectionEnds The connection end points.

System.Collections.Generic.IList<Point> connectionPoints The points of interest (points where the line is curved/segmented).

Returns

Point

GetBezierDefaultHandlePoint(Point, Point, Point)

Gets the bezier default handle point.

Declaration

public static Point GetBezierDefaultHandlePoint(Point entryPoint, Point endPoint, Point connectorCenter)

Parameters

Point entryPoint The entry point.

Point endPoint The end point (opposite of the entryPoint ).

Point connectorCenter The center of the connectors.

Returns

Point

GetBezierDefaultHandlePoint(Point, Point, Point, Double)

Gets the bezier default handle point.

Declaration

public static Point GetBezierDefaultHandlePoint(Point entryPoint, Point endPoint, Point connectorCenter, double bezierTension)

Parameters

Point entryPoint The entry point.

Point endPoint The end point.

Point connectorCenter The connector center.

System.Double bezierTension The bezier tension.

Returns

Point

GetConnectionEndPoints(IConnection, Boolean)

Gets the connection end points.

Declaration

public static Tuple<Point, Point> GetConnectionEndPoints(this IConnection connection, bool useConnectionCoordinates = false)

Parameters

IConnection connection The connection.

System.Boolean useConnectionCoordinates If set to true the points will be in global coordinates. If set to false, then the coordinates will be relative to the connection.

Returns

System.Tuple<Point, Point>

GetDefaultHandleBezierPoints(IConnection, Point, Point, Nullable<Point>, Nullable<Point>)

Gets the default handle bezier points.

Declaration

public static Tuple<Point, Point> GetDefaultHandleBezierPoints(this IConnection connection, Point startPoint, Point endPoint, Point? sourceConnectorCenter = default(Point? ), Point? targetConnectorCenter = default(Point? ))

Parameters

IConnection connection The connection.

Point startPoint The cached start point.

Point endPoint The cached end point.

System.Nullable<Point> sourceConnectorCenter The source connector center.

System.Nullable<Point> targetConnectorCenter The target connector center.

Returns

System.Tuple<Point, Point>

SegmentCount(IConnection)

Returns the number of segments defined by the intermediate points.

Declaration

public static int SegmentCount(this IConnection conn)

Parameters

IConnection conn The connection.

Returns

System.Int32

SetConnectionPoints(IConnection, IEnumerable<Point>)

Sets the connection points.

Declaration

public static void SetConnectionPoints(this IConnection connection, IEnumerable<Point> connectionPoints)

Parameters

IConnection connection The connection.

System.Collections.Generic.IEnumerable<Point> connectionPoints The connection points.

TranslateConnectionPoints(IConnection, Boolean)

Shifts the ConnectionPoints by adding or substracting the Position vector.

Declaration

public static IEnumerable<Point> TranslateConnectionPoints(this IConnection connection, bool globalCoordinates = true)

Parameters

IConnection connection The connection. to shift.

System.Boolean globalCoordinates If set to true points will be transformed to global coordinates. If set to false, then the coordinates will be relative to the connection.

Returns

System.Collections.Generic.IEnumerable<Point>

Remarks

The start/end points are not taken into account here.
