QueryCoords Method—ArcGIS Pro

Copies this CubicBezier curve's control points into the startPt, controlPt1, controlPt2, and endPt parameters. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public void QueryCoords( 
   out MapPoint startPt,
   out Coordinate2D controlPt1,
   out Coordinate2D controlPt2,
   out MapPoint endPt
)

Public Sub QueryCoords( _
   ByRef startPt As MapPoint, _
   ByRef controlPt1 As Coordinate2D, _
   ByRef controlPt2 As Coordinate2D, _
   ByRef endPt As MapPoint _
)

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.

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run.

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
