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

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

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

Methods

impl Matrix

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

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

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

fn uniform_scale(s: f32) -> Self

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

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

Construct a matrix for skewing.
