Box2D to a closed rectangular polygon Geometry. Equivalent to PostGIS box2d::geometry. Degenerate boxes return the appropriate lower-dimensional geometry:
| Box2D shape | Returned geometry |
|---|---|
| Both axes have non-zero extent | POLYGON (closed rectangle) |
One axis collapsed (e.g. xmin == xmax) | LINESTRING along the non-collapsed axis |
Both axes collapsed (xmin == xmax && ymin == ymax) | POINT |
CAST(box AS geometry).
Returns NULL on NULL input.

Parameters
The bounding box to convert to a geometry.
Return type
A closed rectangular polygon (or a lower-dimensional geometry for degenerate boxes).
