            g.DrawArc(p0, new Rectangle(10, 10, radius, radius), stAngle, endAngle);
            g.DrawLine(p1, new Point(rec.X, rec.Top + radius - (radius / 2)), new Point(rec.X, rec.Top + height)) ;
            g.DrawLine(p2, new Point(rec.X, rec.Top + height), new Point(rec.X + width, rec.Top + height));
            g.DrawLine(p3, new Point(rec.X + width, rec.Top + height), new Point(rec.X + width, rec.Top));
            g.DrawLine(p4, new Point(rec.X + width, rec.Top), new Point(rec.X + radius - (radius / 2), rec.Top));

        }

    }



 }

위 그림은 왼쪽 상단만 행한 것.

1. 원하는 지점의 꼭지점에서 원하는 반경 만큼 Fillet을 한다.

    = Arc 를 사용해서 호를 그려준다.

2. 베이스가 된 사각형을 그려주면 된다.

    = Line을 사용해서  (Arc 된 지점 - 사각형의 다른 꼭지점) 의 지점을 그려주면 된다
