ArcGIS.Core.Geometry Namespace / CubicBezierBuilderEx Class / CubicBezierBuilderEx Constructor / CubicBezierBuilderEx Constructor(MapPoint,Coordinate2D,Coordinate2D,MapPoint,SpatialReference)
The point from which the curve starts.
Control point 1 of the cubic bezier.
Control point 2 of the cubic bezier.
The point at which the curve ends.
(Optional) The spatial reference. The default value is null. The spatial references of the input points are ignored.

    In This Topic
    Creates a new instance of the CubicBezierBuilderEx class from four control points.
    Syntax

    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. The spatial references of the input points are ignored.
    Exceptions
    ExceptionDescription
    startPoint or controlPoint1 or controlPoint2 or endPoint is null or empty.
    Example
    Construct a Cubic Bezier - from Coordinates
    // Use a builderEx convenience method or a builderEx constructor.
    
    MapPoint startPt = MapPointBuilderEx.CreateMapPoint(1.0, 1.0, 3.0);
    MapPoint endPt = MapPointBuilderEx.CreateMapPoint(2.0, 2.0, 3.0);
    
    Coordinate2D ctrl1Pt = new Coordinate2D(1.0, 2.0);
    Coordinate2D ctrl2Pt = new Coordinate2D(2.0, 1.0);
    
    // BuilderEx convenience methods don't need to run on the MCT
    CubicBezierSegment bezier = CubicBezierBuilderEx.CreateCubicBezierSegment(startPt, ctrl1Pt, ctrl2Pt, endPt, SpatialReferences.WGS84);
    
    // without a SR
    bezier = CubicBezierBuilderEx.CreateCubicBezierSegment(startPt, ctrl1Pt, ctrl2Pt, endPt);
    
    
    // builderEx constructors don't need to run on the MCT
    CubicBezierBuilderEx cbbEx = new CubicBezierBuilderEx(startPt, ctrl1Pt, ctrl2Pt, endPt);
    bezier = cbbEx.ToSegment() as CubicBezierSegment;
    
    // another alternative
    cbbEx = new CubicBezierBuilderEx(startPt, ctrl1Pt.ToMapPoint(), ctrl2Pt.ToMapPoint(), endPt);
    bezier = cbbEx.ToSegment() as CubicBezierSegment;
