Struct gate::renderer::Affine

pub struct Affine { /* fields omitted */ }

Represents an affine transformation in 2D space.

Methods

impl Affine

pub fn id() -> Affine

Identity transformation.

pub fn translate(x_offset: f64, y_offset: f64) -> Affine

Returns a translation transformation.

pub fn rotate(angle: f64) -> Affine

Returns a rotation transformation, rotating counter-clockwise by angle radians.

pub fn scale_axes(scale_x: f64, scale_y: f64) -> Affine

Returns a scaling transformation, scaling x and y axes separately.

pub fn scale(scale: f64) -> Affine

Returns a scaling transformation, scaling x and y axes identically.

pub fn pre_transform(&self, rhs: &Affine) -> Affine

Returns a transformation that is functionally equivalent to self composed with rhs.

This means that the rhs transformation is invoked first, and then the self transformation is invoked on the output of that. This is usually the desired ordering with graphics transformations.

pub fn pre_scale_axes(&self, scale_x: f64, scale_y: f64) -> Affine

Logically equivalent to self.pre_transform(&Affine::scale_axes(scale_x, scale_y)).

pub fn pre_scale(&self, scale: f64) -> Affine

Logically equivalent to self.pre_transform(&Affine::scale(scale)).

pub fn pre_rotate(&self, angle: f64) -> Affine

Logically equivalent to self.pre_transform(&Affine::rotate(angle)).

pub fn pre_translate(&self, x_offset: f64, y_offset: f64) -> Affine

Logically equivalent to self.pre_transform(&Affine::translate(x_offset, y_offset)).

pub fn post_scale_axes(&self, scale_x: f64, scale_y: f64) -> Affine

Logically equivalent to Affine::scale_axes(scale_x, scale_y).pre_transform(self).

pub fn post_scale(&self, scale: f64) -> Affine

Logically equivalent to Affine::scale(scale).pre_transform(self).

pub fn post_rotate(&self, angle: f64) -> Affine

Logically equivalent to Affine::rotate(angle).pre_transform(self).

pub fn post_translate(&self, x_offset: f64, y_offset: f64) -> Affine

Logically equivalent to Affine::translate(x_offset, y_offset).pre_transform(self).

Trait Implementations

impl Copy for Affine

impl Clone for Affine

fn clone(&self) -> Affine

Returns a copy of the value.
