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

public:
void SetClip(
	RectangleF rect, 
	CombineMode combineMode
)

Parameters

rect
Type: System.Drawing::RectangleF

RectangleF structure to combine.

combineMode
Type: System.Drawing.Drawing2D::CombineMode

Member of 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.

public:
   void SetClipRectangleFCombine( PaintEventArgs^ e )
   {
      // Create rectangle for clipping region.
      RectangleF clipRect = RectangleF(0.0F,0.0F,100.0F,100.0F);

      // Set clipping region of graphics to rectangle.
      e->Graphics->SetClip( clipRect, CombineMode::Replace );

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