Implementations

impl Transform2D

pub fn apply(&self, p: [f32; 2]) -> [f32; 2]

Apply the transform to a point (x, y).

pub fn inverse_apply(&self, p: [f32; 2]) -> Option<[f32; 2]>

Apply the inverse transform to a world-space point. Returns None if non-invertible.

impl Transform2D

pub fn identity() -> Self

pub fn concat(self, other: Self) -> Self

Compose two transforms: self ∘ other (apply other, then self).

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

pub fn translate(tx: f32, ty: f32) -> Self

pub fn rotate(angle: f32) -> Self

Create a rotation transform (angle in radians, counter-clockwise).

pub fn rotate_around(angle: f32, cx: f32, cy: f32) -> Self

Create a rotation transform around a specific center point.
