   {
      // Create a rectangle.
      Rectangle rectangle1 = Rectangle(20,20,50,100);

      // Draw its outline.
      e->Graphics->DrawRectangle( Pens::SlateBlue, rectangle1 );

      // Change the page scale.  
      e->Graphics->PageUnit = GraphicsUnit::Point;

      // Draw the rectangle again.
      e->Graphics->DrawRectangle( Pens::Tomato, rectangle1 );
   }

private void ChangePageUnit(PaintEventArgs e)
{

    // Create a rectangle.
    Rectangle rectangle1 = new Rectangle(20, 20, 50, 100);

    // Draw its outline.
    e.Graphics.DrawRectangle(Pens.SlateBlue, rectangle1);

    // Change the page scale.  
    e.Graphics.PageUnit = GraphicsUnit.Point;

    // Draw the rectangle again.
    e.Graphics.DrawRectangle(Pens.Tomato, rectangle1);
}

Private Sub ChangePageUnit(ByVal e As PaintEventArgs)

    ' Create a rectangle.
    Dim rectangle1 As New Rectangle(20, 20, 50, 100)

    ' Draw its outline.
    e.Graphics.DrawRectangle(Pens.SlateBlue, rectangle1)

    ' Change the page scale.  
    e.Graphics.PageUnit = GraphicsUnit.Point

    ' Draw the rectangle again.
