ST_Scale — Scales the geometry to a new size by multiplying the ordinates with the parameters. Ie: ST_Scale(geom, Xfactor, Yfactor, Zfactor).
geometry ST_Scale(
geometry geomA, float XFactor, float YFactor, float ZFactor)
;
geometry ST_Scale(
geometry geomA, float XFactor, float YFactor)

Prior to 1.3.4, this function crashes if used with geometries that contain CURVES. This is fixed in 1.3.4+ |
Availability: 1.1.0.
Enhanced: 2.0.0 support for Polyhedral surfaces, Triangles and TIN was introduced.
This function supports Polyhedral surfaces.
This function supports 3d and will not drop the z-index.
This method supports Circular Strings and Curves
This function supports Triangles and Triangulated Irregular Network Surfaces (TIN).
