  • Creates a small rectangle for the clipping region.

  • Sets the clipping region to the rectangle with the Replace member.

  • Fills a large rectangle with a solid black brush.

The result is a small, filled, black rectangle.

private void SetClipRegionCombine(PaintEventArgs e)
{

    // Create region for clipping.
    Region clipRegion = new Region(new Rectangle(0, 0, 100, 100));

    // Set clipping region of graphics to region.
    e.Graphics.SetClip(clipRegion, CombineMode.Replace);

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