CreateCubicBezierSegment(MapPoint,MapPoint,MapPoint,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,
   MapPoint controlPoint1,
   MapPoint controlPoint2,
   MapPoint endPoint,
   SpatialReference spatialReference
)

Public Overloads Shared Function CreateCubicBezierSegment( _
   ByVal startPoint As MapPoint, _
   ByVal controlPoint1 As MapPoint, _
   ByVal controlPoint2 As MapPoint, _
   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 MapPoints

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

MapPoint startPt = MapPointBuilderEx.CreateMapPoint(1.0, 1.0, SpatialReferences.WGS84);
MapPoint endPt = MapPointBuilderEx.CreateMapPoint(2.0, 2.0, SpatialReferences.WGS84);

MapPoint ctrl1Pt = MapPointBuilderEx.CreateMapPoint(1.0, 2.0, SpatialReferences.WGS84);
MapPoint ctrl2Pt = MapPointBuilderEx.CreateMapPoint(2.0, 1.0, SpatialReferences.WGS84);

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

// builderEx constructors dont need to run on the MCT
CubicBezierBuilderEx cbbEx = new CubicBezierBuilderEx(startPt, ctrl1Pt, ctrl2Pt, endPt);
bezier = cbbEx.ToSegment() as CubicBezierSegment;

Requirements

Target Platforms: Windows 11, Windows 10, Windows 8.1
