Struct TransformationMatrix 

#[repr(C)]
pub struct TransformationMatrix {
    pub rotation_scale: [[f32; 2]; 2],
    pub translation: [f32; 2],
}

A data type representing a 2 dimensional transformation that can be applied to an element.

Fields

rotation_scale: [[f32; 2]; 2]

2x2 matrix containing rotation and scale, stored row-major

translation: [f32; 2]

translation vector

Implementations

impl TransformationMatrix

pub fn unit() -> Self

The unit matrix, has no effect.

pub fn translate(self, point: Point<ScaledPixels>) -> Self

Move the origin by a given point

pub fn rotate(self, angle: Radians) -> Self

Clockwise rotation in radians around the origin

pub fn scale(self, size: Size<f32>) -> Self

Scale around the origin

pub fn compose(self, other: TransformationMatrix) -> TransformationMatrix

Perform matrix multiplication with another transformation to produce a new transformation that is the result of applying both transformations: first, other, then self.

pub fn apply(&self, point: Point<Pixels>) -> Point<Pixels>

Apply transformation to a point, mainly useful for debugging

Trait Implementations

impl Clone for TransformationMatrix

fn clone(&self) -> TransformationMatrix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransformationMatrix

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

Formats the value using the given formatter.

impl Default for TransformationMatrix

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for TransformationMatrix

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