class Polygon(*args, **kwargs)
Polygon objects may be instantiated by passing in parameters that represent the rings of the polygon. The parameters must either be LinearRing instances, or a sequence that may be used to construct a LinearRing:
>>> ext_coords = ((0, 0), (0, 1), (1, 1), (1, 0), (0, 0)) >>> int_coords = ((0.4, 0.4), (0.4, 0.6), (0.6, 0.6), (0.6, 0.4), (0.4, 0.4)) >>> poly = Polygon(ext_coords, int_coords) >>> poly = Polygon(LinearRing(ext_coords), LinearRing(int_coords))
Changed in Django 1.10:
In previous versions, an empty Polygon couldn’t be instantiated.
-
classmethod from_bbox(bbox) -
Returns a polygon object from the given bounding-box, a 4-tuple comprising
(xmin, ymin, xmax, ymax).
-
num_interior_rings -
Returns the number of interior rings in this geometry.
Comparing Polygons
Note that it is possible to compare Polygon objects directly with < or >, but as the comparison is made through Polygon’s LineString, it does not mean much (but is consistent and quick). You can always force the comparison with the area property:
>>> if poly_1.area > poly_2.area: >>> pass
