Name
CG_Scale — Scales a geometry uniformly in all dimensions by a given factor.
Synopsis
geometry CG_Scale(geometry geom, float8 factor);
Beschreibung
Scales the input geometry geom by a uniform scale factor in all dimensions (X, Y, and Z). The scaling is performed relative to the origin point (0,0,0).
Availability: 3.6.0 - requires SFCGAL >= 2.0.0
Diese Methode benötigt ein SFCGAL-Backend.
Beispiele
SELECT ST_AsText(CG_Scale('LINESTRING(1 1, 2 2)', 2));
-- Result: LINESTRING(2 2, 4 4)
