Implementations§

§

impl Transform2D

pub fn identity() -> Transform2D

Creates an identity transformation with no translation, rotation or scaling applied.

pub fn new( &mut self, a: f32, b: f32, c: f32, d: f32, e: f32, f: f32 ) -> Transform2D

Creates a new transformation matrix.

The parameters are interpreted as matrix as follows: [a c e] [b d f] [0 0 1]

pub fn translate(&mut self, tx: f32, ty: f32)

pub fn rotate(&mut self, a: f32)

pub fn skew_x(&mut self, a: f32)

pub fn skew_y(&mut self, a: f32)

pub fn multiply(&mut self, other: &Transform2D)

pub fn premultiply(&mut self, other: &Transform2D)

pub fn inverse(&mut self)

pub fn inversed(&self) -> Transform2D

pub fn transform_point(&self, sx: f32, sy: f32) -> (f32, f32)

pub fn average_scale(&self) -> f32

pub fn to_mat3x4(self) -> [f32; 12]

pub fn cache_key(&self) -> u64
