Struct Transform2D 

pub struct Transform2D {
    pub matrix: [f32; 6],
}

2D transformation matrix.

Fields

matrix: [f32; 6]

Matrix elements [a, b, c, d, e, f] | a c e | | b d f | | 0 0 1 |

Implementations

impl Transform2D

pub const fn identity() -> Self

Identity transformation.

pub const fn translate(x: f32, y: f32) -> Self

Create a translation transform.

pub const fn scale(sx: f32, sy: f32) -> Self

Create a scale transform.

pub fn rotate(angle: f32) -> Self

Create a rotation transform (radians).

pub fn then(&self, other: &Self) -> Self

Chain transforms: first apply self, then apply other.

For point p: a.then(b).apply(p) == b.apply(a.apply(p))

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

Transform a point.

Trait Implementations

impl Clone for Transform2D

fn clone(&self) -> Transform2D

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transform2D

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

Formats the value using the given formatter.

impl Default for Transform2D

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Transform2D

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Transform2D

fn eq(&self, other: &Transform2D) -> 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.

impl Serialize for Transform2D

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Transform2D
