Struct nanachi::matrix::Matrix2d

pub struct Matrix2d(pub [f64; 6]);

Matrix for affine transformation.

Implementations

impl Matrix2d

pub fn new() -> Matrix2d

Create a Matrix2d that no transform.

pub fn translate(&self, x: f64, y: f64) -> Matrix2d

Create new Matrix2d translated with specified position from myself.

pub fn scale(&self, x: f64, y: f64) -> Matrix2d

Create new Matrix2d scaled with specified size from myself.

pub fn rotate(&self, rad: f64) -> Matrix2d

Create new Matrix2d rotated with specified angle from myself.

pub fn skew_y(&self, dy: f64) -> Matrix2d

Create new Matrix2d skewed with specified y-axis amount from myself.

pub fn skew_x(&self, dx: f64) -> Matrix2d

Create new Matrix2d skewed with specified x-axis amount from myself.

pub fn apply<P: From<Point> + Into<Point>>(&self, p: P) -> P

Transform the Point.

pub fn inverse(&self) -> Matrix2d

Inverse the matrix Ideally, matrix2d.inverse().inverse() == matrix2d.

pub fn then(&self, rhs: &Matrix2d) -> Matrix2d

Return the multiplication of the two matrices.

pub fn is_unit(&self) -> bool

Return whether it is unit matrix.

pub fn is_direct(&self) -> bool

Return whether it is directly or indirectly. An indirect matrix makes path flip.

impl Copy for Matrix2d

impl Debug for Matrix2d

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

Formats the value using the given formatter.

impl Default for Matrix2d

pub fn default() -> Self

Returns the "default value" for a type.

impl PartialEq<Matrix2d> for Matrix2d

pub fn eq(&self, other: &Matrix2d) -> bool
