ST_Affine (Python)

Apply a 3D/2D affine transformation to the given geometry. x = a * x + b * y + c * z + xOff | x = a * x + b * y + xOff y = d * x + e * y + f * z + yOff | y = d * x + e * y + yOff z = g * x + h * y + i * z + zOff The 3D form is used only when c, f, g, h, i and zOff are all given.
