Struct Matrix 

pub struct Matrix {
    pub a: f64,
    pub b: f64,
    pub c: f64,
    pub d: f64,
    pub e: f64,
    pub f: f64,
}

An affine transformation.

Fields

a: f64

Row 1, column 1.

b: f64

Row 1, column 2.

c: f64

Row 2, column 1.

d: f64

Row 2, column 2.

e: f64

Translation x.

f: f64

Translation y.

Implementations

impl Matrix

pub const IDENTITY: Matrix

The identity.

pub const fn new(a: f64, b: f64, c: f64, d: f64, e: f64, f: f64) -> Matrix

A matrix from its six numbers.

pub const fn translate(x: f64, y: f64) -> Matrix

A translation.

pub fn from_slice(v: &[f64]) -> Option<Matrix>

From six operands, if they are all finite numbers.

pub fn then(&self, other: &Matrix) -> Matrix

self then other: points are transformed by self first.

pub fn apply(&self, x: f64, y: f64) -> (f64, f64)

Transforms a point.

pub fn apply_vector(&self, x: f64, y: f64) -> (f64, f64)

Transforms a vector (no translation).

Trait Implementations

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

Performs copy-assignment from source.

impl Copy for Matrix

impl Debug for Matrix

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

impl Default for Matrix

fn default() -> Matrix

Returns the “default value” for a type.

impl PartialEq for Matrix

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

Equality operator ==.
