AnnPolygonObject Class

Summary

Defines an annotation polygon object.

Syntax

C++

public class AnnPolygonObject : Leadtools.Windows.Annotations.AnnPolylineObject, Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnPolygon, Leadtools.Windows.Annotations.IAnnPolyline

Public Class AnnPolygonObject  
   Inherits Leadtools.Windows.Annotations.AnnPolylineObject 
   Implements Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnPolygon, Leadtools.Windows.Annotations.IAnnPolyline

public ref class AnnPolygonObject : public Leadtools.Windows.Annotations.AnnPolylineObject, Leadtools.Windows.Annotations.IAnnHeader, Leadtools.Windows.Annotations.IAnnObject, Leadtools.Windows.Annotations.IAnnPolygon, Leadtools.Windows.Annotations.IAnnPolyline

Remarks

The polygon object is a simple polygon that contains a collection of System.Windows.Point points, a stroke and a fill. The polygon can be IsClosed or not, and can also have a certain FillRule. For an illustration of the different fill modes, refer to FillRule enumeration.

For more information about the polygon annotation object refer to AnnPolygonObject for WPF. For more information about the automated polygon annotation object, refer to WPF Annotation Objects - Automated Features.

Example

This example creates a new closed polygon object with 4 points.
