A LinearRing is a closed, one-dimensional feature. A LinearRing that crosses itself or touches itself at a single point is invalid and operations on it may fail. Parameters ---------- coordinates : sequence A sequence of (x, y [,z]) numeric coordinate pairs or triples, or an array-like with shape (N, 2) or (N, 3). Also can be a sequence of Point objects. Notes ----- Rings are automatically closed. There is no need to specify a final coordinate pair identical to the first. Examples -------- Construct a square ring. >>> ring = LinearRing( ((0, 0), (0, 1), (1 ,1 ), (1 , 0)) ) >>> ring.is_closed True >>> list(ring.coords) [(0.0, 0.0), (0.0, 1.0), (1.0, 1.0), (1.0, 0.0), (0.0, 0.0)] >>> ring.length 4.0 Ncs|dur tdSt|tr!t|tkr|S|jstd|j}n5t |dr+t |}t|t j r:t |jt jr:nddt fdd|D}t |jt jsVtdt|d kratdSt|}t|tsotd |S) NzLINEARRING EMPTYz"An input LineString must be valid. __array__cSs"t|tr |jdSdd|DS)NrcSg|]}t|qSr)float.0crrr [z7LinearRing.__new__.._coords..) isinstancercoords)orrr_coordsWs  z#LinearRing.__new__.._coordscsg|]}|qSrr)rr"r#rrr]rz&LinearRing.__new__..z&Inconsistent coordinate dimensionalityrz/Invalid values passed to LinearRing constructor)r from_wktr rtyper is_validrr!hasattrnpasarrayndarray issubdtypedtypenumberarray ValueErrorlenr)self coordinatesgeomrr$r__new__>s0         zLinearRing.__new__cCsdt|jdS)Nr r&r3)tupler!r2rrr__geo_interface__mszLinearRing.__geo_interface__cCsttj|ddffS)zWKB doesn't differentiate between LineString and LinearRing so we need to move the coordinate sequence into the correct geometry typeT) include_srid)rr to_wkbr8rrr __reduce__qszLinearRing.__reduce__cCstt|S)z/True is the ring is oriented counter clock-wise)boolrr8rrris_ccwvszLinearRing.is_ccwcCstt|S)zsTrue if the geometry is simple, meaning that any self-intersections are only at boundary points, else False)r=r is_simpler8rrrr?{szLinearRing.is_simpler ) __name__ __module__ __qualname____doc__ __slots__r5propertyr9r<r>r?rrrrr s" /  c@sLeZdZdZdZdZdZddZddZddZ d d Z d d Z d dZ dS)InteriorRingSequenceNrcCs||_|j|_dSr )_parent_ndim)r2parentrrr__init__s zInteriorRingSequence.__init__cCsd|_||_|S)Nr)_index__len___lengthr8rrr__iter__s zInteriorRingSequence.__iter__cCs.|j|jkr||j}|jd7_|St)N)rLrN _get_ring StopIteration)r2ringrrr__next__s  zInteriorRingSequence.__next__cCs t|jSr )r get_num_interior_ringsrHr8rrrrMs zInteriorRingSequence.__len__cCs|}t|tr'||dks||krtd|dkr ||}n|}||St|trIg}||\}}}t|||D] }|||q<|St d)Nrzindex out of rangezkey must be an index or slice) rMr int IndexErrorrQsliceindicesrangeappend TypeError)r2keymiresstartstopstriderrr __getitem__s    z InteriorRingSequence.__getitem__cCst|j|Sr )r get_interior_ringrH)r2r_rrrrQszInteriorRingSequence._get_ring) r@rArBrHrIrLrNrKrOrTrMrdrQrrrrrGs rGc@sdeZdZdZgZdddZeddZeddZed d Z ed d Z dddZ e ddZ dS)raE A geometry type representing an area that is enclosed by a linear ring. A polygon is a two-dimensional feature and has a non-zero area. It may have one or more negative-space "holes" which are also bounded by linear rings. If any rings cross each other, the feature is invalid and operations on it may fail. Parameters ---------- shell : sequence A sequence of (x, y [,z]) numeric coordinate pairs or triples, or an array-like with shape (N, 2) or (N, 3). Also can be a sequence of Point objects. holes : sequence A sequence of objects which satisfy the same requirements as the shell parameters above Attributes ---------- exterior : LinearRing The ring which bounds the positive space of the polygon. interiors : sequence A sequence of rings which bound all existing holes. Examples -------- Create a square polygon with no holes >>> coords = ((0., 0.), (0., 1.), (1., 1.), (1., 0.), (0., 0.)) >>> polygon = Polygon(coords) >>> polygon.area 1.0 NcCst|dur tdSt|tr|St|}|dur(t|dkr!d}ndd|D}tj||d}t|ts8td|S)Nz POLYGON EMPTYrcSrr)r )rrSrrrrrz#Polygon.__new__..)holesz,Invalid values passed to Polygon constructor)r r%r rr r1polygonsr0)r2shellrfr4rrrr5s    zPolygon.__new__cCs t|Sr )r get_exterior_ringr8rrrexteriors zPolygon.exteriorcCs|jrgSt|Sr )is_emptyrGr8rrr interiorsszPolygon.interiorscCstd)NzCComponent rings have coordinate sequences, but the polygon does not)NotImplementedErrorr8rrrr!szPolygon.coordscCsJ|jtkr g}nt|jjg}|jD] }|t|jqdt|dS)Nrr6)rjr r7r!rlr[)r2r!holerrrr9s  zPolygon.__geo_interface__?cCs||jrdS|dur|jrdnd}|durd}dd|jjDg}dd|jD}d d d||D}d d ||||S) aReturns SVG path element for the Polygon geometry.
