CreateCubicBezierSegment(MapPoint,Coordinate2D,Coordinate2D,MapPoint,SpatialReference) Method

In This Topic

Convenience method to create a new instance of the CubicBezierSegment class from four control points.

Syntax

C#
Visual Basic (Declaration)

public static CubicBezierSegment CreateCubicBezierSegment( 
   MapPoint startPoint,
   Coordinate2D controlPoint1,
   Coordinate2D controlPoint2,
   MapPoint endPoint,
   SpatialReference spatialReference
)

Public Overloads Shared Function CreateCubicBezierSegment( _
   ByVal startPoint As MapPoint, _
   ByVal controlPoint1 As Coordinate2D, _
   ByVal controlPoint2 As Coordinate2D, _
   ByVal endPoint As MapPoint, _
   Optional ByVal spatialReference As SpatialReference _
) As CubicBezierSegment

Parameters

startPoint: The start point.
controlPoint1: Control point 1 of the cubic bezier.
controlPoint2: Control point 2 of the cubic bezier.
endPoint: The end point.
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;
