Implementations

impl AffineTransform

pub const fn identity() -> Self

The identity transform.

pub fn translate(dx: f32, dy: f32) -> Self

A pure translation transform.

pub const fn scale(sx: f32, sy: f32) -> Self

A pure scale transform.

pub fn rotate(angle: f32) -> Self

A rotation transform by angle radians.

pub fn apply(&self, x: f32, y: f32) -> (f32, f32)

Apply this transform to a point.

pub fn then(&self, rhs: &AffineTransform) -> Self

Compose: self after rhs (rhs is applied first, then self).

pub fn inverse(&self) -> Option<Self>

Returns the inverse transform, or None when the matrix is singular.
