Name
CG_Rotate — Rotates a geometry by a given angle around the origin (0,0).
Übersicht
geometry CG_Rotate(geometry geom, float8 angle);
Beschreibung
Rotates the input geometry geom by angle radians around the origin point (0,0). The rotation is performed in 2D space; Z coordinates are not modified. Positive angles rotate the geometry counter-clockwise.
Availability: 3.6.0 - requires SFCGAL >= 2.0.0
Diese Methode benötigt ein SFCGAL-Backend.
Beispiele
Code
SELECT CG_Rotate('LINESTRING(1 0,0 1)', pi()/2);
