CubicBezierBuilderEx Constructor(Coordinate2D,Coordinate2D,Coordinate2D,Coordinate2D,SpatialReference)

In This Topic

Creates a new instance of the CubicBezierBuilderEx class from four control points.

Syntax

C#
Visual Basic (Declaration)

public CubicBezierBuilderEx( 
   Coordinate2D startPoint,
   Coordinate2D controlPoint1,
   Coordinate2D controlPoint2,
   Coordinate2D endPoint,
   SpatialReference spatialReference
)

Public Function New( _
   ByVal startPoint As Coordinate2D, _
   ByVal controlPoint1 As Coordinate2D, _
   ByVal controlPoint2 As Coordinate2D, _
   ByVal endPoint As Coordinate2D, _
   Optional ByVal spatialReference As SpatialReference _
)

Parameters

startPoint: The point from which the curve starts.
controlPoint1: Control point 1 of the cubic bezier.
controlPoint2: Control point 2 of the cubic bezier.
endPoint: The point at which the curve ends.
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 Text Element

//Must be on QueuedTask.Run(() => { ...

//Build geometry
Coordinate2D pt1 = new Coordinate2D(3.5, 7.5);
Coordinate2D pt2 = new Coordinate2D(4.16, 8);
Coordinate2D pt3 = new Coordinate2D(4.83, 7.1);
Coordinate2D pt4 = new Coordinate2D(5.5, 7.5);
var bez = new CubicBezierBuilderEx(pt1, pt2, pt3, pt4);
var bezSeg = bez.ToSegment();
Polyline bezPl = PolylineBuilderEx.CreatePolyline(bezSeg, AttributeFlags.AllAttributes);

//Set symbolology, create and add element to layout
CIMTextSymbol sym = SymbolFactory.Instance.ConstructTextSymbol(
  ColorFactory.Instance.BlackRGB, 24, "Comic Sans MS", "Regular");

var ge = ElementFactory.Instance.CreateTextGraphicElement(
  container, TextType.SplinedText, bezPl, sym, "this is the bezier text",
        "New Bezier Text", true, new ElementInfo() { Anchor = Anchor.CenterPoint });
