Struct Transform

pub struct Transform {
    pub xx: f32,
    pub yx: f32,
    pub xy: f32,
    pub yy: f32,
    pub dx: f32,
    pub dy: f32,
}

A transformation matrix to be applied to the drawing canvas.

Factors are specified in column-order, meaning that for a vector (x,y) the transformed position x' of the vector is calculated by x' = xx * x + xy * y + dx, and the transformed position y’ is calculated by y' = yx * x + yy * y + dy.

Fields

xx: f32

yx: f32

xy: f32

yy: f32

dx: f32

dy: f32

Trait Implementations

impl Clone for Transform

fn clone(&self) -> Transform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Transform

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

Formats the value using the given formatter.

impl Default for Transform

fn default() -> Self

Returns the “default value” for a type.

impl Mul for Transform

type Output = Transform

The resulting type after applying the * operator.

fn mul(self, rhs: Self) -> Self::Output

Performs the * operation.

impl MulAssign for Transform

fn mul_assign(&mut self, rhs: Self)

Performs the *= operation.

impl PartialEq for Transform

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