Graphics.SetClip Method (GraphicsPath)

 

Sets the clipping region of this Graphics to the specified GraphicsPath.

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

public void SetClip(
	GraphicsPath path
)

Parameters

path
Type: System.Drawing.Drawing2D.GraphicsPath

GraphicsPath that represents the new clip region.

If the graphics path represented by the path parameter is not closed, an additional segment is added from the last point to the first point to close the path.

The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a graphics path and adds an ellipse to the path.

  • Sets the clipping region to the elliptical path.

  • Fills a large rectangle with a solid black brush.

The result is a filled, black ellipse.

private void SetClipPath(PaintEventArgs e)
{

    // Create graphics path.
    GraphicsPath clipPath = new GraphicsPath();
    clipPath.AddEllipse(0, 0, 200, 100);

    // Set clipping region to path.
    e.Graphics.SetClip(clipPath);

    // Fill rectangle to demonstrate clipping region.
    e.Graphics.FillRectangle(new SolidBrush(Color.Black), 0, 0, 500, 300);
}
