Struct forma_render::math::AffineTransform

pub struct AffineTransform {
    pub ux: f32,
    pub uy: f32,
    pub vx: f32,
    pub vy: f32,
    pub tx: f32,
    pub ty: f32,
}

2D transformation that preserves parallel lines.

Such a transformation can combine translation, scale, flip, rotate and shears. It is represented by a 3 by 3 matrix where the last row is [0, 0, 1].

[ x' ]   [ u.x v.x t.x ] [ x ]
[ y' ] = [ u.y v.y t.y ] [ y ]
[ 1  ]   [   0   0   1 ] [ 1 ]

Fields

ux: f32

uy: f32

vx: f32

vy: f32

tx: f32

ty: f32

Implementations

impl AffineTransform

pub fn to_array(&self) -> [f32; 6]

Trait Implementations

impl Clone for AffineTransform

fn clone(&self) -> AffineTransform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AffineTransform

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

Formats the value using the given formatter.

impl Default for AffineTransform

fn default() -> Self

Returns the “default value” for a type.

impl From<[f32; 6]> for AffineTransform

fn from(transform: [f32; 6]) -> Self

Converts to this type from the input type.

impl Hash for AffineTransform

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<AffineTransform> for AffineTransform

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<AffineTransform> for GeomPresTransform

type Error = GeomPresTransformError

The type returned in the event of a conversion error.

fn try_from(t: AffineTransform) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for AffineTransform

impl Eq for AffineTransform
