Struct ttf_parser::Transform

pub struct Transform {
    pub a: f32,
    pub b: f32,
    pub c: f32,
    pub d: f32,
    pub e: f32,
    pub f: f32,
}

An affine transform.

Fields

a: f32

The ‘a’ component of the transform.

b: f32

The ‘b’ component of the transform.

c: f32

The ‘c’ component of the transform.

d: f32

The ‘d’ component of the transform.

e: f32

The ‘e’ component of the transform.

f: f32

The ‘f’ component of the transform.

Implementations

impl Transform

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

Creates a new transform with the specified components.

pub fn new_translate(tx: f32, ty: f32) -> Self

Creates a new translation transform.

pub fn new_rotate(angle: f32) -> Self

Creates a new rotation transform.

pub fn new_skew(skew_x: f32, skew_y: f32) -> Self

Creates a new skew transform.

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

Creates a new scale transform.

pub fn combine(ts1: Self, ts2: Self) -> Self

Combines two transforms with each other.

pub(crate) fn apply_to(&self, x: &mut f32, y: &mut f32)

pub fn is_default(&self) -> bool

Checks whether a transform is the identity transform.

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 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.
