background of bezier curve

   Bezier curve incorrectly covers its background.
the code:

		int li_width = 100 * 30;
		int li_height = 100 * 20;
		HDC hDC = DPL.GetCanvasDC(li_width, li_height);

		CDC dc;
		CDC* pDC = CDC::FromHandle(hDC);

		CRect l_rect(100, 100, 1000, 1000);
		pDC->FillSolidRect(l_rect, RGB(255, 255, 0));

		CPoint l_points[4] = {
			CPoint(760, 460),
			CPoint(800, 380),
			CPoint(920, 380),
			CPoint(960, 460)
		};

		pDC->PolyBezier(l_points, 4);
		int li_result = DPL.LoadFromCanvasDC(254, 3);

expected reult: yellow rectangle with a bezier curve, without any white space

result: please see this screenshot:
