Struct Projection 

pub struct Projection { /* private fields */ }

Affine transformation between shape space and pixel space.

Implementations

impl Projection

pub fn new(scale: Vector2, translate: Vector2) -> Self

pub fn project(&self, coord: ShapePoint) -> PixelPoint

Shape coordinate → pixel coordinate (typed boundary crossing).

pub fn unproject(&self, coord: PixelPoint) -> ShapePoint

Pixel coordinate → shape coordinate (typed boundary crossing).

pub fn project_vector(&self, v: Vector2) -> Vector2

pub fn unproject_vector(&self, v: Vector2) -> Vector2

pub fn project_x(&self, x: f64) -> f64

pub fn project_y(&self, y: f64) -> f64

pub fn unproject_x(&self, x: f64) -> f64

pub fn unproject_y(&self, y: f64) -> f64

pub fn scale(&self) -> Vector2

pub fn translate(&self) -> Vector2
