Graphics.Clip Property

Modifying the Region object returned by the Clip property does not affect subsequent drawing with the Graphics object. To change the clip region, replace the Clip property value with a new Region object. To determine whether the clipping region is infinite, retrieve the Clip property and call its IsInfinite method.

The following code example demonstrates the use of the Clip property. This example is designed to be used with Windows Forms. Paste the code into a form and call the SetAndFillClip method when handling the form's Paint event, passing e as PaintEventArgs.

private void SetAndFillClip(PaintEventArgs e)
{

    // Set the Clip property to a new region.
    e.Graphics.Clip = new Region(new Rectangle(10, 10, 100, 200));

    // Fill the region.
    e.Graphics.FillRegion(Brushes.LightSalmon, e.Graphics.Clip);

    // Demonstrate the clip region by drawing a string 
    // at the outer edge of the region.
    e.Graphics.DrawString("Outside of Clip", new Font("Arial", 
        12.0F, FontStyle.Regular), Brushes.Black, 0.0F, 0.0F);

}
