Examples

The following code example demonstrates the effects of setting the Width and LineJoin properties on a Pen.

This example is designed to be used with Windows Forms. Paste the code into a form and call the ShowLineJoin method when handling the form's Paint event, passing e as PaintEventArgs .

private:
   void ShowLineJoin( PaintEventArgs^ e )
   {
      // Create a new pen.
      Pen^ skyBluePen = gcnew Pen( Brushes::DeepSkyBlue );

      // Set the pen's width.
      skyBluePen->Width = 8.0F;

      // Set the LineJoin property.
      skyBluePen->LineJoin = System::Drawing::Drawing2D::LineJoin::Bevel;

      // Draw a rectangle.
      e->Graphics->DrawRectangle( skyBluePen, Rectangle(40,40,150,200) );

      //Dispose of the pen.
      delete skyBluePen;
   }

private void ShowLineJoin(PaintEventArgs e)
{

    // Create a new pen.
    Pen skyBluePen = new Pen(Brushes.DeepSkyBlue);

    // Set the pen's width.
    skyBluePen.Width = 8.0F;

    // Set the LineJoin property.
    skyBluePen.LineJoin = System.Drawing.Drawing2D.LineJoin.Bevel;

    // Draw a rectangle.
    e.Graphics.DrawRectangle(skyBluePen, 
        new Rectangle(40, 40, 150, 200));

    //Dispose of the pen.
    skyBluePen.Dispose();
}

Private Sub ShowLineJoin(ByVal e As PaintEventArgs)

    ' Create a new pen.
    Dim skyBluePen As New Pen(Brushes.DeepSkyBlue)

    ' Set the pen's width.
    skyBluePen.Width = 8.0F

    ' Set the LineJoin property.
    skyBluePen.LineJoin = Drawing2D.LineJoin.Bevel

    ' Draw a rectangle.
    e.Graphics.DrawRectangle(skyBluePen, _
        New Rectangle(40, 40, 150, 200))

    'Dispose of the pen.
    skyBluePen.Dispose()

End Sub

Remarks

A line join is the common area that is formed by two lines whose ends meet or overlap. There are three line join styles: miter, bevel, and round. When you specify a line join style for a Pen object, that join style will be applied to all the connected lines in any GraphicsPath object drawn using that pen. The following illustration shows the results of the beveled line join example.
