Struct Transform 

pub struct Transform {
    pub matrix: FontMatrix,
    pub scale: Option<Fixed>,
}

Combination of a matrix and optional scale.

Fields

matrix: FontMatrix

Affine font matrix.

scale: Option<Fixed>

Fixed point scale factor.

This is assumed to convert from font units to 26.6 values.

Implementations

impl Transform

pub const IDENTITY: Self

The transform that doesn’t modify coordinates or metrics.

pub fn compute_scale(ppem: f32, upem: i32) -> Fixed

Computes a scale factor for the given ppem and upem values.

pub fn transform_h_metric(&self, metric: Fixed) -> Fixed

Applies the transform to a horizontal metric such as an advance width.

Trait Implementations

impl Clone for Transform

fn clone(&self) -> Transform

Returns a duplicate 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() -> Transform

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.

impl Copy for Transform

impl Eq for Transform

impl StructuralPartialEq for Transform
