  • Draws the cloned portion to the screen.

private:
   void Clone_Example1( PaintEventArgs^ e )
   {
      // Create a Bitmap object from a file.
      Bitmap^ myBitmap = gcnew Bitmap( "Grapes.jpg" );

      // Clone a portion of the Bitmap object.
      Rectangle cloneRect = Rectangle(0,0,100,100);
