    ReQL command: polygon_sub

    Command syntax

    polygon1.polygon_sub(polygon2) → polygon

    Description

    Use polygon2 to “punch out” a hole in polygon1. polygon2 must be completely contained within polygon1 and must have no holes itself (it must not be the output of polygon_sub itself).

    Example: Define a polygon with a hole punched in it.

    outer_polygon = r.polygon(
        [-122.4, 37.7],
        [-122.4, 37.3],
        [-121.8, 37.3],
        [-121.8, 37.7]
    )
    inner_polygon = r.polygon(
        [-122.3, 37.4],
        [-122.3, 37.6],
        [-122.0, 37.6],
        [-122.0, 37.4]
    )
    outer_polygon.polygon_sub(inner_polygon).run(conn)
