Struct Matrix 

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

2D affine transform in PDF row-vector convention: (x' y' 1) = (x y 1) x M. Used for both the graphics-state CTM (cm/q/Q) and the text matrix/text-line matrix (Tm/Td/TD/T*).

Fields

a: f64

b: f64

c: f64

d: f64

e: f64

f: f64

Implementations

impl Matrix

pub const IDENTITY: Matrix

pub fn translation(tx: f64, ty: f64) -> Matrix

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

self composed with (applied before) other: self x other.

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

Transforms point (row vector) through this matrix.

pub fn origin(self) -> (f64, f64)

This matrix’s translation component — for a text matrix, the run’s PDF-space origin.

pub fn translate_text(&mut self, tx: f64, ty: f64)

Post-show horizontal advance (PDF spec 9.4.3): self = [1 0 0 1 tx ty] x self.

Trait Implementations

impl Copy for Matrix

impl Debug for Matrix

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

Formats the value using the given formatter.

impl PartialEq for Matrix

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

Equality operator ==.
