该判断多边形点时钟排列方向， 非常准确（不准确的还没有遇到过，快3年了）。 该函数用到的相关函数都在文档中： 1.PtoLDistance－点到直线的距离； 2.CalcPolygonRect－计算多边形外接矩形； 3.CalcSegmentRect－计算线段外接矩形； 4.Distance－计算两点距离； 5.ISZEROA－判断数值是否为零； 该函数数据类型为Windows的POINT，使用了标准模板vector-The polygon points to determine the direction of the clock with very accurate (inaccurate, not yet encountered, fast 3 years). The function of the correlation function used in the document: 1.PtoLDistance-point to the straight-line distance 2.CalcPolygonRect-calculated external rectangular polygon 3.CalcSegmentRect-computing segment external rectangle 4.Distance-computing two distance 5 . ISZEROA-judge whether the value is zero the function data type for the Windows-POINT, using the standard template vector
