Name

ST_TransScale — returns a copy of a shape with all coordinates shifted by the provided dX, dY and then multiplied by Xfactor and Yfactor.

Synopsis

ST_TransScale ( in shape any ,
  in dX any ,
  in dY any ,
  in Xfactor any ,
  in Yfactor any );
 

Description

returns a copy of a shape with all coordinates shifted by the provided dX, dY and then multiplied by Xfactor and Yfactor. Different values for Xfactor and Yfactor will result in distorted arcs.

Parameters

shape

Geometry.

dX

X coordinate.

dY

Y coordinate.

Xfactor

X value to multiple by.

Yfactor

Y value to multiple by.

Return Types

Returns any.
