Struct Transform2 

pub struct Transform2 { /* private fields */ }

A homogeneous 2D transform matrix.

Implementations

impl Transform2

pub const fn new(matrix: [[f64; 3]; 3]) -> Transform2

Creates a transform from a 3x3 homogeneous matrix.

pub const fn identity() -> Transform2

Returns the identity transform.

pub const fn translation(translation: Translation) -> Transform2

Creates a 2D translation transform.

pub const fn scale(scale: Scale) -> Transform2

Creates a 2D scale transform.

pub fn rotation(rotation: Rotation) -> Transform2

Creates a 2D rotation transform.

pub const fn matrix(self) -> [[f64; 3]; 3]

Returns the underlying matrix.

pub fn apply_point(self, point: (f64, f64)) -> (f64, f64)

Applies the transform to a 2D point tuple.

Trait Implementations

impl Clone for Transform2

fn clone(&self) -> Transform2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transform2

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

Formats the value using the given formatter.

impl PartialEq for Transform2

fn eq(&self, other: &Transform2) -> 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.
