pysal.lib.cg.get_polygon_point_intersect¶

pysal.lib.cg.get_polygon_point_intersect(poly, pt)[源代码]¶

返回多边形与点的交点。

获取多边形交点（多边形，点）->点

参数:	poly : 检查交叉点的多边形 pt : 检查交叉点的点

实例

>>> poly = Polygon([Point((0, 0)), Point((1, 0)), Point((1, 1)), Point((0, 1))])
>>> pt = Point((0.5, 0.5))
>>> i = get_polygon_point_intersect(poly, pt)
>>> str(i)
'(0.5, 0.5)'
>>> pt2 = Point((2, 2))
>>> get_polygon_point_intersect(poly, pt2)
