MFC 根据点画曲线

根据点画曲线：

PolyBezier:point数组大小必须是4

    CClientDC dc(this);

    POINT *point =new POINT[4];

point[0].x = 0;

    point[0].y =200;

    point[1].x =40;

    point[1].y =140;

    point[2].x =80;

    point[2].y =140;

    point[3].x =120;

    point[3].y =180;

    dc.PolyBezier(point,4);

 

PolyBezierTo:point数组大小必须是3

 

    CClientDC dc(this);

    POINT *point =new POINT[4];

    point[0].x = 0;

    point[0].y =200;

    point[1].x =40;

    point[1].y =60;

    point[2].x =80;

    point[2].y =20;

    dc.PolyBezierTo(point,3);
