Chain
(vertices)[source]¶Geometric representation of a chain, also known as a polyline.
vertices
listReturns the vertices of the chain in clockwise order.
len
floatReturns the geometric length of the chain.
__init__
(self, vertices)[source]¶Returns a chain created from the points specified.
__init__(Point list or list of Point lists) -> Chain
Examples
>>> c = Chain([Point((0, 0)), Point((1, 0)), Point((1, 1)), Point((2, 1))])
