ST_CurvePolygon( ST_Curve , ST

Creates a curve polygon from a curve representing the exterior ring and a list of curves representing interior rings, all in a specified spatial reference system.

Syntax

NEW ST_CurvePolygon( ST_Curve exterior_ring, ST_Curve interior_ringi)

Parameters

exterior_ring – The exterior ring of the curve polygon
interior_ringi – Interior rings of the curve polygon

Returns

ST_CurvePolygon Returns a polygon from the specified exterior ring and interior rings.

Examples

Example 1 – The following returns CurvePolygon ((-5 -1, 5 -1, 0 9, -5 -1), CircularString (-2 2, -2 4, 2 4, 2 2, -2 2)) (a triangle with a circular hole).
```
SELECT NEW ST_CurvePolygon(
NEW ST_LineString ('LineString (-5 -1, 5 -1, 0 9, -5 -1)'),
NEW ST_CircularString ('CircularString (-2 2, -2 4, 2 4, 2 2, -2 2)'))
```
