Struct Matrix 

pub struct Matrix { /* private fields */ }

An Matrix holds an affine transformation, usually used to reshape glyphs.
A small set of matrix operations are provided to manipulate these.

Implementations

impl Matrix

pub fn new() -> Matrix

Initialize an Matrix to the identity matrix.

pub fn rotate(&mut self, cos: f64, sin: f64)

Rotate a matrix

Rotates matrix by the angle who’s sine is sin and cosine is cos.
This is done by multiplying by the matrix:

pub fn scale(&mut self, sx: f64, dy: f64)

Scale a matrix

Multiplies matrix x values by sx and y values by dy.
This is done by multiplying by the matrix:

pub fn shear(&mut self, sh: f64, sv: f64)

Shear a matrix

Shears matrix horizontally by sh and vertically by sv.
This is done by multiplying by the matrix:

pub fn xx(&self) -> f64

xx field.

pub fn xy(&self) -> f64

xy field.

pub fn yx(&self) -> f64

yx field

pub fn yy(&self) -> f64

yy field

Trait Implementations

impl Clone for Matrix

fn clone(&self) -> Matrix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Matrix

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

Formats the value using the given formatter.

impl Default for Matrix

fn default() -> Self

Returns the “default value” for a type.

impl Mul for Matrix

type Output = Matrix

The resulting type after applying the * operator.

fn mul(self, other: Matrix) -> Matrix

Performs the * operation.

impl PartialEq for Matrix

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