Struct Affine 

pub struct Affine(/* private fields */);

A 2D affine transform stored as six coefficients [a, b, c, d, e, f], row-major, mapping a point (x, y) to:

x' = a·x + c·y + e
y' = b·x + d·y + f

This matches the column convention used by SVG/PostScript matrix(...) and by oxideav-core’s Transform2D; stipple-render converts between the two at the render boundary.

Implementations

impl Affine

pub const IDENTITY: Self

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

pub const fn translate(v: Vec2) -> Self

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

pub fn rotate(radians: f64) -> Self

pub const fn as_array(self) -> [f64; 6]

pub fn then(self, outer: Affine) -> Affine

Compose so that self is applied after inner (result(p) = self(inner(p))).

pub fn apply(self, p: Point) -> Point

Apply the transform to a point.

pub fn determinant(self) -> f64

The determinant of the linear (2×2) part.

pub fn inverse(self) -> Option<Affine>

Matrix inverse, or None if the transform is singular.

Trait Implementations

impl Clone for Affine

fn clone(&self) -> Affine

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Affine

impl Debug for Affine

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

Formats the value using the given formatter.

impl Default for Affine

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Affine

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