libpysal.cg.get_polygon_point_intersect(poly, pt)[source]¶

Returns the intersection of a polygon and point.

Parameters:¶

poly : libpysal.cg.Polygon¶

A polygon to check for an intersection.

pt : libpysal.cg.Point¶

A point to check poly for an intersection.

Returns:¶

ret – The intersection of a poly and pt if one exists, otherwise None.

Return type:¶

{libpysal.cg.Point, None}

Examples

>>> 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)
