CreateCubicBezierSegment(Coordinate2D,Coordinate2D,Coordinate2D,Coordinate2D,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( 
   Coordinate2D startPoint,
   Coordinate2D controlPoint1,
   Coordinate2D controlPoint2,
   Coordinate2D endPoint,
   SpatialReference spatialReference
)

Public Overloads Shared Function CreateCubicBezierSegment( _
   ByVal startPoint As Coordinate2D, _
   ByVal controlPoint1 As Coordinate2D, _
   ByVal controlPoint2 As Coordinate2D, _
   ByVal endPoint As Coordinate2D, _
   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.

Exceptions

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

Example

Create Bezier Curve Element

//Must be on QueuedTask.Run(() => { ...
//Build geometry
Coordinate2D pt1 = new Coordinate2D(1, 7.5);
Coordinate2D pt2 = new Coordinate2D(1.66, 8);
Coordinate2D pt3 = new Coordinate2D(2.33, 7.1);
Coordinate2D pt4 = new Coordinate2D(3, 7.5);
var bez = new CubicBezierBuilderEx(pt1, pt2, pt3, pt4);
var bezSeg = bez.ToSegment();
Polyline bezPl = PolylineBuilderEx.CreatePolyline(bezSeg, AttributeFlags.AllAttributes);

//Set symbology, create and add element to layout
CIMLineSymbol lineSym = SymbolFactory.Instance.ConstructLineSymbol(
  ColorFactory.Instance.RedRGB, 4.0, SimpleLineStyle.DashDot);

ElementFactory.Instance.CreateGraphicElement(container, bezPl, lineSym, "New Bezier");
