    pub d: f64,
    pub e: f64,
    pub f: f64,
}

Implementations

impl Mat

pub const IDENTITY: Mat

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

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

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

pub fn from_slice(v: &[f64]) -> Option<Mat>

From a six-element array, None unless every entry is finite.

pub fn then(self, r: Mat) -> Mat

self × r: apply self first, then r (PDF’s cm prepends the new matrix to the CTM: new_ctm = m × ctm).

pub fn apply(self, x: f64, y: f64) -> (f64, f64)

pub fn apply_vec(self, x: f64, y: f64) -> (f64, f64)

The linear part applied to a vector (no translation).

pub fn det(self) -> f64

pub fn mean_scale(self) -> f64

sqrt(|det|): the geometric mean scale — what docling-parse scales a line width by (pdf_state<SHAPE>::trafo_scale).

pub fn max_scale(self) -> f64

The larger singular value: the most a unit length can stretch.

pub fn invert(self) -> Option<Mat>

pub fn is_finite(self) -> bool

pub fn to_ts(self) -> Transform

The same transform for tiny-skia (f32; from_row(sx, ky, kx, sy, tx, ty) takes the matrix in the same a b c d e f order).

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

The axis-aligned bounding box of the unit square under this matrix, (x_min, y_min, x_max, y_max).
