Struct Matrix 

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

3x2 affine transformation matrix.

PDF uses the representation [a b c d e f] which maps: x’ = ax + cy + e y’ = bx + dy + f

Fields

a: f64

b: f64

c: f64

d: f64

e: f64

f: f64

Implementations

impl Matrix

pub fn identity() -> Self

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

pub fn translate(tx: f64, ty: f64) -> Self

pub fn scale(sx: f64, sy: f64) -> Self

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

Matrix multiply: self * other.

Represents applying other first, then self. PDF cm semantics: new_CTM = old_CTM.concat(cm_matrix).

pub fn determinant(&self) -> f64

pub fn inverse(&self) -> Option<Self>

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 Copy for Matrix

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 PartialEq for Matrix

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