Width Property

Pen.Width Property

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

Namespace:  System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

public float Width { get; set; }

Property Value

Type: System.Single
The width of this Pen.

ExceptionCondition
ArgumentException

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

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.

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 = 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();

}
