CG_Scale — Scales a geometry uniformly in all dimensions by a given factor.
요약
geometry CG_Scale(geometry geom, float8 factor);
설명
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
This method needs SFCGAL backend.
