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

Public Sub SetClip (
	path As GraphicsPath,
	combineMode As CombineMode


Type: System.Drawing.Drawing2D.GraphicsPath

GraphicsPath to combine.

Type: System.Drawing.Drawing2D.CombineMode

Member of the CombineMode enumeration that specifies the combining operation to use.

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 with the Replace member.

  • Fills a large rectangle with a solid black brush.

The result is a filled, black ellipse.

Private Sub SetClipPathCombine(ByVal e As PaintEventArgs)

    ' Create graphics path.
    Dim clipPath As New GraphicsPath
    clipPath.AddEllipse(0, 0, 200, 100)

    ' Set clipping region to path.
    e.Graphics.SetClip(clipPath, CombineMode.Replace)

    ' Fill rectangle to demonstrate clipping region.
    e.Graphics.FillRectangle(New SolidBrush(Color.Black), 0, 0, _
    500, 300)
End Sub
