Description

Convert a Line object into a Polygon object. If the last point does not specify the same coordinates as the first point, polygon will close the polygon by connecting them.

Longitude (−180 to 180) and latitude (−90 to 90) of vertices are plotted on a perfect sphere. See Geospatial support for more information on ReQL’s coordinate system.

If the last point does not specify the same coordinates as the first point, polygon will close the polygon by connecting them. You cannot directly construct a polygon with holes in it using polygon, but you can use polygon_sub to use a second polygon within the interior of the first to define a hole.

Example: Create a line object and then convert it to a polygon.

r.table('geo').insert({
    'id': 201,
    'rectangle': r.line(
        [-122.423246, 37.779388],
        [-122.423246, 37.329898],
        [-121.886420, 37.329898],
        [-121.886420, 37.779388]
    )
}).run(conn)

r.table('geo').get(201).update({
    'rectangle': r.row['rectangle'].fill()
}, non_atomic=True).run(conn)
