Expand description

IGlyphProvider extracts the font data from the font. Note (Possibly block unsafe): If a Font is dummy (lazy loaded), it will block current thread and fetch the font data from the server.

Required Methods§

Source

fn ligature_glyph(&self, font: &Font, id: GlyphId) -> Option<ImmutStr>

With font with glyph id, return the raw ligature string. See FontGlyphProvider::ligature_glyph for the default implementation.

Source

fn svg_glyph(&self, font: &Font, id: GlyphId) -> Option<Arc<[u8]>>

With font with glyph id, return the svg document data. Note: The returned data is possibly compressed. See FontGlyphProvider::svg_glyph for the default implementation.

Source

fn bitmap_glyph( &self, font: &Font, id: GlyphId, ppem: u16, ) -> Option<(TypstImage, i16, i16)>

With font with glyph id, return the bitmap image data. Optionally, with given ppem, return the best fit bitmap image. Return the best quality bitmap image if ppem is std::u16::MAX. See FontGlyphProvider::bitmap_glyph for the default implementation.

Source

fn outline_glyph(&self, font: &Font, id: GlyphId) -> Option<String>

With font with glyph id, return the outline path data. The returned data is in Path2D format. See FontGlyphProvider::outline_glyph for the default implementation.
