ST_CurvePolyToPoly() method

Returns the interpolation of the curve polygon as a polygon.

Syntax

curvepolygon-expression.ST_CurvePolyToPoly()

ST_Polygon Returns the interpolation of the curvepolygon-expression as a polygon.

Example 1 – The following example returns the result Polygon ((0 0, 2 0, 1 2, 0 0)) (a copy of the original polygon).
```
SELECT TREAT( Shape AS ST_Polygon ).ST_CurvePolyToPoly()
FROM SpatialShapes WHERE ShapeID = 16
```
The following example returns the result Polygon ((0 0, 5 0, 5 10, 0 0))(the curve polygon converted to an equivalent polygon).
```
SELECT NEW ST_CurvePolygon( 'CurvePolygon(CompoundCurve((0 0, 5 10, 5 0, 0 0)))' )
.ST_CurvePolyToPoly()
```
The following returns an interpolated polygon which approximates the original curve polygon.
```
SELECT TREAT( Shape AS ST_CurvePolygon ).ST_CurvePolyToPoly()
FROM SpatialShapes WHERE ShapeId = 24
```
