本过程是用光滑的曲线(三次参数样条曲线)连接离散点



参数PicHdc表示在上面进行处理的窗体的设备环境句柄



参数PicHwnd表示在上面进行处理的窗体的窗口句柄



参数X(),Y()表示各离散点的坐标



参数Color表示曲线颜色



参数Mode表示三次参数样条曲线的约束条件：



其中0为自由端，1为抛物端(没有考虑夹持端)-This process is a smooth curve (parametric cubic spline curve) to connect discrete points PicHdc express in the above parameters to deal with the form of equipment, the environment handle PicHwnd express in the above parameters to deal with the window handle of the form parameters of X () , Y () express the coordinates of the discrete points that the curve parameters Color Color Mode parameters express the three parameters of the spline curve constraint conditions: where 0 is the free end, one for the parabolic-side (does not take gripping side)
