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

Visual Basic

Copy Code

Private Sub AnnPolygonObject_AnnPolygonObject(ByVal container As AnnContainer)   Dim polygon As AnnPolygonObject = New AnnPolygonObject()     polygon.Points.Add(New System.Windows.Point(100, 100))     polygon.Points.Add(New System.Windows.Point(200, 100))     polygon.Points.Add(New System.Windows.Point(200, 200))     polygon.Points.Add(New System.Windows.Point(100, 300))   polygon.Stroke = Brushes.Red   polygon.StrokeThickness = 1.0   polygon.Fill = Brushes.White   polygon.FillRule = FillRule.EvenOdd   polygon.IsClosed = True   container.Children.Add(polygon) End Sub

The polygon object is a simple polygon that contains a collection of Point points, a stroke and a fill. The polygon can be AnnPolygonObject.IsClosed or not, and can also have a certain AnnPolygonObject.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.
