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

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 startPt,
   MapPoint controlPt1,
   MapPoint controlPt2,
   MapPoint endPt,
   SpatialReference spatialReference
)

Public Overloads Shared Function CreateCubicBezierSegment( _
   ByVal startPt As MapPoint, _
   ByVal controlPt1 As MapPoint, _
   ByVal controlPt2 As MapPoint, _
   ByVal endPt As MapPoint, _
   Optional ByVal spatialReference As SpatialReference _
) As CubicBezierSegment

Parameters

startPt: The start point.
controlPt1: Control point 1 of the cubic bezier.
controlPt2: Control point 2 of the cubic bezier.
endPt: The end point.
spatialReference: (Optional) The spatial reference. If spatialReference is null, then the spatial reference is inherited from startPt or endPt.

Exceptions

Exception	Description
System.InvalidOperationException	Incompatible spatial references.
System.ArgumentNullException	startPt or controlPt1 or controlPt2 or endPt is null.
GeometryObjectException	An operation on an empty geometry was attempted. startPt or controlPt1 or controlPt2 or endPt is empty.

Example

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

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

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

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

// Builder constructors need to run on the MCT
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
  using (CubicBezierBuilder cbb = new CubicBezierBuilder(startPt, ctrl1Pt, ctrl2Pt, endPt))
  {
    // do something with the builder

    CubicBezierSegment bezier = cbb.ToSegment();
  }
});
