LabelPoint Method (GeometryEngine)

In This Topic

Performs the LabelPoint operation on the geometry.

Syntax

C#
Visual Basic (Declaration)

public MapPoint LabelPoint( 
   Geometry geometry
)

Public Function LabelPoint( _
   ByVal geometry As Geometry _
) As MapPoint

Parameters

geometry: The polygon or envelope to label.

Return Value

Returns the label point for the geometry.

Exceptions

Exception	Description
System.ArgumentNullException	Geometry is null or empty.
System.NotImplementedException	The method is not implemented for GeometryBag.
System.ArgumentException	Geometry is not a polygon or an envelope.

Example

Determine label point for a Polygon

// create a polygon
List<Coordinate2D> list2D = new List<Coordinate2D>();
list2D.Add(new Coordinate2D(1.0, 1.0));
list2D.Add(new Coordinate2D(1.0, 2.0));
list2D.Add(new Coordinate2D(2.0, 2.0));
list2D.Add(new Coordinate2D(2.0, 1.0));

Polygon polygon = PolygonBuilderEx.CreatePolygon(list2D);
bool isSimple = GeometryEngine.Instance.IsSimpleAsFeature(polygon);
MapPoint pt = GeometryEngine.Instance.LabelPoint(polygon);

Requirements

Target Platforms: Windows 11, Windows 10, Windows 8.1
