Example
 
Private Sub viewer_InteractiveRegionEllipse(ByVal sender As Object, ByVal e As RasterViewerRectangleEventArgs)
   Console.WriteLine("InteractiveRegionEllipse: e.Rectangle {0}, e.Status {1}, e.Cancel {2}", e.Rectangle, e.Status, e.Cancel)
End Sub
Public Sub RasterImageViewer_InteractiveRegionEllipse(ByVal viewer As RasterImageViewer)
   viewer.InteractiveMode = RasterViewerInteractiveMode.Region
   viewer.InteractiveRegionType = RasterViewerInteractiveRegionType.Ellipse
   AddHandler viewer.InteractiveRegionEllipse, AddressOf viewer_InteractiveRegionEllipse

   ' Draw the mouse on image to draw an elliptical region
   ' After you are done, you must remove the event handler as in below
   '
   ' viewer.InteractiveRegionEllipse -= new EventHandler<RasterViewerRectangleEventArgs>(viewer_InteractiveRegionEllipse);
End Sub
private void viewer_InteractiveRegionEllipse(object sender, RasterViewerRectangleEventArgs e)
{
   Console.WriteLine("InteractiveRegionEllipse: e.Rectangle {0}, e.Status {1}, e.Cancel {2}", e.Rectangle, e.Status, e.Cancel);
}
public void RasterImageViewer_InteractiveRegionEllipse(RasterImageViewer viewer)
{
   viewer.InteractiveMode = RasterViewerInteractiveMode.Region;
   viewer.InteractiveRegionType = RasterViewerInteractiveRegionType.Ellipse;
   viewer.InteractiveRegionEllipse += new EventHandler<RasterViewerRectangleEventArgs>(viewer_InteractiveRegionEllipse);

   // Draw the mouse on image to draw an elliptical region
   // After you are done, you must remove the event handler as in below
