Example

This example adds a new point object to a container.

Visual BasicCopy Code
Private Sub AnnPointObject_AnnPointObject(ByVal viewer As RasterImageViewer, ByVal container As AnnContainer)
   Dim point As AnnPointObject = New AnnPointObject()
   point.CenterPoint = New AnnPoint(100, 100, AnnUnit.Pixel)
   point.ShowPicture = True
   ' default picture, no need to change anything
   container.Objects.Add(point)
   viewer.Invalidate(point.InvalidRectangle)
   MessageBox.Show("Picture")

   ' show with a radius
   point.Radius = New AnnLength(16, AnnUnit.Pixel)
   point.Pen = New AnnPen(Color.Red, New AnnLength(1, AnnUnit.Pixel))
   point.ShowPicture = False
   viewer.Invalidate(point.InvalidRectangle)
   MessageBox.Show("No picture")
End Sub
C#Copy Code
private void AnnPointObject_AnnPointObject(RasterImageViewer viewer, AnnContainer container) 

   AnnPointObject point = new AnnPointObject(); 
   point.CenterPoint = new AnnPoint(100, 100, AnnUnit.Pixel); 
   point.ShowPicture = true; 
   // default picture, no need to change anything 
   container.Objects.Add(point); 
   viewer.Invalidate(point.InvalidRectangle); 
   MessageBox.Show("Picture"); 
 
   // show with a radius 
   point.Radius = new AnnLength(16, AnnUnit.Pixel); 
   point.Pen = new AnnPen(Color.Red, new AnnLength(1, AnnUnit.Pixel)); 
   point.ShowPicture = false; 
   viewer.Invalidate(point.InvalidRectangle); 
   MessageBox.Show("No picture"); 
}

Remarks

The point object is a single point. This object works in two ways: If the value of ShowPicture is true; this object will draw the picture in Picture with CenterPoint as the center point. Pen, Brush and Radius will be ignored. If ShowPicture is false; this object will draw an ellipse using Pen, Brush and Radius around CenterPoint.

This class implements the IAnnPictureObject interface and accesses the Picture property that handles the picture associated with the annotation object.
