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. >>> from shapely import LinearRing >>> 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 Nc|tjdSt|tr6t |t ur|S|jstd|j}nt|drtj |}t|tj r%tj |jtjrnVdtjfd|D}tj |jtjst#dt%|dkrtjdStj|}t|t st#d |S) z!Create a new LinearRing geometry.NzLINEARRING EMPTYz"An input LineString must be valid. __array__c^t|tr |jdSd|DS)Nrc,g|]}t|S)float.0cs r z7LinearRing.__new__.._coords..[s444Qa444r) isinstancercoords)os r_coordsz#LinearRing.__new__.._coordsWs4!!U++5 x{*44!4444rc&g|] }|Srr)r"r'r(s rr$z&LinearRing.__new__..]s!'H'H'Hq 'H'H'Hrz&Inconsistent coordinate dimensionalityrz/Invalid values passed to LinearRing constructor)rfrom_wktr%rtyper is_validrr&hasattrnpasarrayndarray issubdtypedtypenumberarray ValueErrorlen linearrings)self coordinatesgeomr(s @r__new__zLinearRing.__new__=s  #$677 7  Z 0 0 OK  J.."" ) 1&'KLLL*0 {K00 6 j55 +rz22 Or}!2988 O555 !h'H'H'H'HK'H'H'HII }[%6 BBO%%MNNN {  q #$677 7";//$ ++ PNOO O rc0dt|jdS)z9Return a GeoJSON-like mapping of the LinearRing geometry.r r+r9)tupler&r8s r__geo_interface__zLinearRing.__geo_interface__ms%U4;5G5GHHHrc>ttj|dffS)zPickle support.
