Struct Transform 

pub struct Transform {
    pub matrix: Mat2x2,
    pub offset: Vec2,
}

A 2-dimensional affine transformation.

Fields

matrix: Mat2x2

offset: Vec2

Implementations

impl Transform

pub fn new(matrix: Mat2x2, offset: Vec2) -> Transform

Constructs an affine transformation from the given transformation matrix and translation vector.

pub fn id() -> Transform

Constructs an identity transformation.

pub fn translate(x: f32, y: f32) -> Transform

Constructs a translation.

pub fn scale(scale: f32) -> Transform

Constructs a uniform scaling.

pub fn rotate(angle: f32) -> Transform

Constructs a rotation.

pub fn then(self, transform: Transform) -> Transform

Sequentially composes two affine transformations.

pub fn apply(self, vec: Vec2) -> Vec2

Applies the affine transformation to the given vector.

Trait Implementations

impl Clone for Transform

fn clone(&self) -> Transform

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Transform

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Transform

fn eq(&self, other: &Transform) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Transform

impl StructuralPartialEq for Transform
