using Leadtools.WinForms; 
 
public AnnFreehandDrawDesigner AnnFreehandDrawDesigner_AnnFreehandDrawDesigner(RasterImageViewer viewer, AnnContainer container) 
{ 
   // start a new freehand draw designer 
   AnnFreehandDrawDesigner freehandDrawDesigner = new AnnFreehandDrawDesigner(); 
 
   // set up the object template (a 2 pixels-wide polyline) 
   AnnPolylineObject polylineObject = 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; 
   freehandDrawDesigner.Owner = viewer; 
   freehandDrawDesigner.ClipCursor = true;
