CubicBezierBuilderEx Constructor(MapPoint,Coordinate2D,Coordinate2D,MapPoint,SpatialReference)

In This Topic

Creates a new instance of the CubicBezierBuilderEx class from four control points.

Syntax

C#
Visual Basic (Declaration)

public CubicBezierBuilderEx( 
   MapPoint startPoint,
   Coordinate2D controlPoint1,
   Coordinate2D controlPoint2,
   MapPoint endPoint,
   SpatialReference spatialReference
)

Public Function New( _
   ByVal startPoint As MapPoint, _
   ByVal controlPoint1 As Coordinate2D, _
   ByVal controlPoint2 As Coordinate2D, _
   ByVal endPoint As MapPoint, _
   Optional ByVal spatialReference As SpatialReference _
)

Parameters

startPoint: The point from which the curve starts.
controlPoint1: Control point 1 of the cubic bezier.
controlPoint2: Control point 2 of the cubic bezier.
endPoint: The point at which the curve ends.
spatialReference: (Optional) The spatial reference. The default value is null. The spatial references of the input points are ignored.

Exceptions

Exception	Description
System.ArgumentNullException	startPoint or controlPoint1 or controlPoint2 or endPoint is null or empty.

Example

Construct a Cubic Bezier - from Coordinates

// Use a builderEx convenience method or a builderEx constructor.

MapPoint startPt = MapPointBuilderEx.CreateMapPoint(1.0, 1.0, 3.0);
MapPoint endPt = MapPointBuilderEx.CreateMapPoint(2.0, 2.0, 3.0);

Coordinate2D ctrl1Pt = new Coordinate2D(1.0, 2.0);
Coordinate2D ctrl2Pt = new Coordinate2D(2.0, 1.0);

// BuilderEx convenience methods don't need to run on the MCT
CubicBezierSegment bezier = CubicBezierBuilderEx.CreateCubicBezierSegment(startPt, ctrl1Pt, ctrl2Pt, endPt, SpatialReferences.WGS84);

// without a SR
bezier = CubicBezierBuilderEx.CreateCubicBezierSegment(startPt, ctrl1Pt, ctrl2Pt, endPt);


// builderEx constructors don't need to run on the MCT
CubicBezierBuilderEx cbbEx = new CubicBezierBuilderEx(startPt, ctrl1Pt, ctrl2Pt, endPt);
bezier = cbbEx.ToSegment() as CubicBezierSegment;

// another alternative
cbbEx = new CubicBezierBuilderEx(startPt, ctrl1Pt.ToMapPoint(), ctrl2Pt.ToMapPoint(), endPt);
bezier = cbbEx.ToSegment() as CubicBezierSegment;
