Public Function AnnFreehandDrawDesigner_AnnFreehandDrawDesigner(ByVal viewer As RasterImageViewer, ByVal container As AnnContainer) As AnnFreehandDrawDesigner
   ' start a new freehand draw designer
   Dim freehandDrawDesigner As AnnFreehandDrawDesigner = New AnnFreehandDrawDesigner()
   ' set up the object template (a 2 pixels-wide polyline)
   Dim polylineObject As AnnPolylineObject = New AnnPolylineObject()
   polylineObject.Pen = New AnnPen(Color.Red, New AnnLength(2, AnnUnit.Pixel))

   ' set up the spacing of the freehand designer
   freehandDrawDesigner.Spacing = 2

   ' initialize the rest of the designer
   freehandDrawDesigner.ObjectTemplate = polylineObject
