ReQL command: polygonSub

Command syntax

polygon1.polygonSub(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 polygonSub itself).

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

import com.rethinkdb.gen.ast.Polygon;

Polygon outerPolygon = r.polygon(
    [-122.4,37.7],
    [-122.4,37.3],
    [-121.8,37.3],
    [-121.8,37.7]
);
Polygon innerPolygon = r.polygon(
    [-122.3,37.4],
    [-122.3,37.6],
    [-122.0,37.6],
    [-122.0,37.4]
);
outerPolygon.polygonSub(inner_polygon).run(conn);
