Struct kas_core::text::fonts::ScaledFaceRef

impl ScaledFaceRef

pub fn face(&self) -> FaceRef

Unscaled face

pub fn dpu(&self) -> DPU

Scale

pub fn h_advance(&self, id: GlyphId) -> f32

Horizontal advancement after this glyph, without shaping or kerning

pub fn h_side_bearing(&self, id: GlyphId) -> f32

Descender

pub fn line_gap(&self) -> f32

Line gap

pub fn height(&self) -> f32

Line height

pub fn underline_metrics(&self) -> Option<LineMetrics>

Metrics for underline

pub fn strikethrough_metrics(&self) -> Option<LineMetrics>

Metrics for strike-through

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
