CubicBezierBuilder Constructor(CubicBezierSegment)

Creates a new instance of the CubicBezierBuilder class from another cubic bezier segment. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public CubicBezierBuilder( 
   CubicBezierSegment cubicBezier
)

Public Function New( _
   ByVal cubicBezier As CubicBezierSegment _
)

Parameters

cubicBezier: The cubic bezier whose control points will be used to construct the CubicBezierBuilder.

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run.
System.ArgumentNullException	cubicBezier is null.
GeometryObjectException	An operation on an empty geometry was attempted. cubicBezier is empty.

Example

// Builder constructors need to run on the MCT.
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
  // retrieve the bezier curve's control points
  using (CubicBezierBuilder cbb = new CubicBezierBuilder(bezierSegment))
  {
    MapPoint startPt = cbb.StartPoint;
    Coordinate2D ctrlPt1 = cbb.ControlPoint1;
    Coordinate2D ctrlPt2 = cbb.ControlPoint2;
    MapPoint endPt = cbb.EndPoint;

    // or use the QueryCoords method
    cbb.QueryCoords(out startPt, out ctrlPt1, out ctrlPt2, out endPt);
  }
});

CubicBezierBuilder cbbEx = new CubicBezierBuilder(bezierSegment);
MapPoint startPtEx = cbbEx.StartPoint;
Coordinate2D ctrlPt1Ex = cbbEx.ControlPoint1;
Coordinate2D ctrlPt2Ex = cbbEx.ControlPoint2;
MapPoint endPtEx = cbbEx.EndPoint;
     
// or use the QueryCoords method
cbbEx.QueryCoords(out startPtEx, out ctrlPt1Ex, out ctrlPt2Ex, out endPtEx);

Requirements

Target Platforms: Windows 11, Windows 10, Windows 8.1
