Pen.Width Pen.Width Pen.Width Pen.Width Property


Gets or sets the width of this Pen, in units of the Graphics object used for drawing.

 property float Width { float get(); void set(float value); };
public float Width { get; set; }
member this.Width : single with get, set
Public Property Width As Single

Property Value

The width of this Pen.


The Width property is set on an immutable Pen, such as those returned by the Pens class.


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.

   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.
        new Rectangle(40, 40, 150, 200));

    //Dispose of the pen.

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.

End Sub


You can access the unit of measure of the Graphics object using its PageUnit property. The unit of measure is typically pixels. A Width of 0 will result in the Pen drawing as if the Width were 1.
