Struct GlyphFallback 

pub struct GlyphFallback { /* private fields */ }

The Arial stand-in LoadSubstFace("Arial", …) builds on first miss.

Implementations

impl GlyphFallback

pub fn id(&self) -> FontId

This stand-in’s identity, for glyph-cache keys.

pub fn gid(&self, unicode: &[char], code: CharCode) -> Option<Gid>

The glyph Arial draws for this character, or None when Arial has none either (FallbackGlyphFromCharcode returning -1).

Unicode comes from the host’s UnicodeFromCharCode; an empty mapping falls back to the raw character code, which is what the C++ passes to GetCharIndex.

pub fn hinted_path(&self, gid: Gid) -> Option<BezPath>

A glyph’s outline, grid-fitted at 64 ppem, for the bitmap path.

pub fn advance(&self, gid: Gid) -> i32

The face’s own advance for this glyph, in 1000/em units. The spacing heuristic compares this to the host font’s /Widths.

pub fn render_synth( &self, xx: i32, xy: i32, vertical: bool, ) -> Option<SynthGlyph>

The synthetic italic and embolden the bitmap path applies, resolved against the device matrix. Arial is never a CID font.
