Example

This example creates a freehand hotspot object.

Visual BasicCopy Code
Private Sub AnnFreehandHotspotObject_AnnFreehandHotspotObject(ByVal container As AnnContainer)
   Dim freehandHotspot As AnnFreehandHotspotObject = New AnnFreehandHotspotObject()
   freehandHotspot.Points.Add(New AnnPoint(100, 100, AnnUnit.Pixel))
   freehandHotspot.Points.Add(New AnnPoint(200, 100, AnnUnit.Pixel))
   freehandHotspot.Points.Add(New AnnPoint(200, 200, AnnUnit.Pixel))
   freehandHotspot.Points.Add(New AnnPoint(100, 300, AnnUnit.Pixel))
   container.Objects.Add(freehandHotspot)
End Sub
C#Copy Code
private void AnnFreehandHotspotObject_AnnFreehandHotspotObject(AnnContainer container)
{
   AnnFreehandHotspotObject freehandHotspot = new AnnFreehandHotspotObject();
   freehandHotspot.Points.Add(new AnnPoint(100, 100, AnnUnit.Pixel));
   freehandHotspot.Points.Add(new AnnPoint(200, 100, AnnUnit.Pixel));
   freehandHotspot.Points.Add(new AnnPoint(200, 200, AnnUnit.Pixel));
   freehandHotspot.Points.Add(new AnnPoint(100, 300, AnnUnit.Pixel));
   container.Objects.Add(freehandHotspot);
}

Remarks

The freehand hot spot annotation object is designed to work as a scaled picture drawn inside a collection of points that create a sequence of joined lines. The freehand hot spot object will draw the picture if the owner container is in design mode. If the container is in run mode, the freehand hot spot object will not draw the picture.
