Struct femtovg::Transform2D

pub struct Transform2D(pub [f32; 6]);

2×3 matrix (2 rows, 3 columns) used for 2D linear transformations. It can represent transformations such as translation, rotation, or scaling.

Tuple Fields

0: [f32; 6]

Implementations

impl Transform2D

pub fn identity() -> Self

Creates an identity transformation with no translation, rotation or scaling applied.

pub fn new(&mut self, a: f32, b: f32, c: f32, d: f32, e: f32, f: f32) -> Self

Creates a new transformation matrix.

The parameters are interpreted as matrix as follows: [a c e] [b d f] [0 0 1]

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

pub fn translate(&mut self, tx: f32, ty: f32)

pub fn scale(&mut self, sx: f32, sy: f32)

pub fn rotate(&mut self, a: f32)

pub fn skew_x(&mut self, a: f32)

pub fn skew_y(&mut self, a: f32)

pub fn multiply(&mut self, other: &Self)

pub fn premultiply(&mut self, other: &Self)

pub fn inverse(&mut self)

pub fn inversed(&self) -> Self

pub fn transform_point(&self, sx: f32, sy: f32) -> (f32, f32)

pub fn average_scale(&self) -> f32

pub fn to_mat3x4(self) -> [f32; 12]

pub fn cache_key(&self) -> u64

Trait Implementations

impl Clone for Transform2D

fn clone(&self) -> Transform2D

Returns a copy 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 Index<usize> for Transform2D

type Output = f32

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IndexMut<usize> for Transform2D

fn index_mut(&mut self, index: usize) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl PartialEq for Transform2D

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

fn partial_cmp(&self, other: &Transform2D) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
