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

  • Creates a temporary Graphics from the thisFormForm of the example.

  • Sets the clipping region of the temporary Graphics to a small square.

  • Updates the clipping region of the form's graphic object to that of the new Graphics with the Replace member.

  • Fills a large rectangle with a solid black brush.

The result is a small, filled, black square.

private void SetClipGraphicsCombine(PaintEventArgs e)

    // Create temporary graphics object and set its clipping region.
    Graphics newGraphics = this.CreateGraphics();
    newGraphics.SetClip(new Rectangle(0, 0, 100, 100));

    // Update clipping region of graphics to clipping region of new

    // graphics.
    e.Graphics.SetClip(newGraphics, CombineMode.Replace);

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

    // Release new graphics.
