Arguments

transform1: A transform
transform2: A transform

Description

Thepremultiply-transforms function premultiplies the partial 3 x 3 matrix represented by transform1 by the partial 3 x 3 matrix represented by transform2, storing the result in transform1. In the result, the translation, scaling and rotation operations contained in transform2 are effectively performed before those in transform1.

transform1 = transform2 . transform1
