Struct Outlines 

pub struct Outlines {
    face: Face<'static>,
    metrics: Metrics,
    traced: RefCell<HashMap<GlyphId, Arc<[PathCommand]>>>,
}

A face’s outlines, traced on demand and kept: a label redrawn every frame traces its glyphs once.

Fields

face: Face<'static>

metrics: Metrics

traced: RefCell<HashMap<GlyphId, Arc<[PathCommand]>>>

Implementations

impl Outlines

pub fn new(typeface: FontChoice) -> Self

Panics

If the typeface’s embedded bytes are not a font this can read.

pub fn metrics(&self) -> Metrics

The metrics the Shaper over the same typeface lays rows out by, so a consumer scales these outlines the way that layout was measured.

pub fn glyph_index(&self, chr: char) -> Option<GlyphId>

The glyph a face’s character map files chr under — the identity a layout that carries none falls back to.

pub fn outline(&self, id: GlyphId) -> Arc<[PathCommand]>

id’s contours, empty where the glyph draws nothing (a space, an unmapped character).
