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

public void SetClip(
	Region region,
	CombineMode combineMode
)

Parameters

region
Type: System.Drawing.Region
Region to combine.
combineMode
Type: System.Drawing.Drawing2D.CombineMode
Member from the CombineMode enumeration that specifies the combining operation to use.

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

  • 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);
}
