IDP.Math.KGeomLib.offsetPath2dWithDistances() method
偏移一组有序的2d曲线，每条曲线的偏移值单独设置 若 delta 大于零，曲线偏移方向为左边；若 delta 小于零，曲线偏移方向为右边 例如：考虑一条逆时针绕向的 path，若 delta 皆大于零，则 path 将向外扩张；若 delta 皆小于零，则 path 将向内收缩
Offset a 2d path with different distances. If the delta > 0, the path will be offset at right side, else if delta < 0, the path will be offset at left side. For example: A CCW path, if delta > 0, the path will be enlarged. if delta < 0, the path will be shrinked.
Signature:
offsetPath2dWithDistances(path: KBoundedCurve2d[], deltas: number[], disTol?: number, cosTol?: number): KPath2dOffsetRet;
Links: offsetPath2dWithDistances(path: KBoundedCurve2d[], deltas: number[], disTol?: number, cosTol?: number): KPath2dOffsetRet;
Parameters

Returns:
返回偏移结果。
Return offset path result.
