Dim point1 As PointF = New PointF (100F, 100F)
Dim point2 As PointF = New PointF (200F, 100F)
Dim point3 As PointF = New PointF (200F, 200F)
Dim point4 As PointF = New PointF (100F, 200F)
Dim curvepoints As PointF () = {point1, point2, point3, point4}
G. DrawPolygon (New Pen (Color. Blue, 2), curvepoints)
'// Text Representation
Dim FFamily As FontFamily = New FontFamily ("Arial ")
