Expand description

2D affine transformation matrix: [a b c d e f] Represents the transform: x’ = ax + cy + e, y’ = bx + dy + f

Fields§

§a: f64

Horizontal skewing component.

§c: f64

Vertical skewing component.

§d: f64

Vertical scaling component.

§e: f64

Horizontal translation.

§f: f64

Vertical translation.
