Struct pdf_canvas::graphicsstate::Matrix

pub struct Matrix { /* fields omitted */ }

A transformation matrix for the pdf graphics state.

Matrixes can be created with numerous named constructors and combined by multiplication.

Examples

canvas.concat(Matrix::translate(10.0, 24.0))?;

// Matrixes can be combined by multiplication:
canvas.concat(Matrix::translate(7.0, 0.0) * Matrix::rotate_deg(45.0))?;
// ... will be visualy identical to:
canvas.concat(Matrix::translate(7.0, 0.0))?;
canvas.concat(Matrix::rotate_deg(45.0))?;

Methods

impl Matrix

pub fn translate(dx: f32, dy: f32) -> Self

Construct a matrix for translation

pub fn rotate(a: f32) -> Self

Construct a matrix for rotating by a radians.

pub fn rotate_deg(a: f32) -> Self

Construct a matrix for rotating by a degrees.

pub fn scale(sx: f32, sy: f32) -> Self

Construct a matrix for scaling by factor sx in x-direction and by sy in y-direction.

pub fn uniform_scale(s: f32) -> Self

Construct a matrix for scaling by the same factor, s in both directions.

pub fn skew(a: f32, b: f32) -> Self

Construct a matrix for skewing.
