    ' Create rectangle for clipping region.
    Dim clipRect As New RectangleF(0.0F, 0.0F, 100.0F, 100.0F)

    ' Set clipping region of graphics to rectangle.
    e.Graphics.SetClip(clipRect, CombineMode.Replace)

    ' Fill rectangle to demonstrate clip region.
    e.Graphics.FillRectangle(New SolidBrush(Color.Black), 0, 0, _
