This method draws a cardinal spline that passes through each point in the array 此方法绘制经过数组中每个点的基数样条。
Overloaded . fills the interior of a closed cardinal spline curve defined by an array of 结构数组定义的闭合基数样条曲线的内部。
This method draws a closed cardinal spline that passes through each point in the array 此方法绘制经过数组中每个点的闭合基数样条。
A cardinal spline curve is used because the curve travels through each of the points in the array 由于曲线经过数组中的每个点，因此使用基数样条曲线。
Gdi supports several types of curves : ellipses , arcs , cardinal splines , and bzier splines Gdi +支持多种类型的曲线：椭圆、弧形、基数样条和贝塞尔样条。
This method fills the interior of a closed cardinal spline that passes through each point in the array 此方法填充经过该数组中每一点的闭合基数样条的内部。
Creates a path and adds the closed cardinal spline curves to the path closed from the endpoint to the starting point 创建路径并向该路径添加闭合的基数样条曲线（从终结点向起始点闭合） 。
You can add several types of curves ellipses , arcs , cardinal splines to a path , but each curve is converted to a bzier spline before it is stored in the path 可以将多种类型的曲线（椭圆、弧形和基数样条）添加到路径，但在存储到路径之前，各种曲线都被转换为贝塞尔样条。
A cardinal spline is defined by an array of points and a tension parameter the curve passes smoothly through each point in the array , and the tension parameter influences the way the curve bends 基数样条由一系列点和张力参数定义，即曲线平滑地通过系列中的每个点，张力参数影响曲线的弯曲方式。
