Implementations

impl FontImpl

pub fn new( atlas: Arc<Mutex<TextureAtlas>>, pixels_per_point: f32, name: String, ab_glyph_font: FontArc, scale_in_pixels: f32, tweak: FontTweak, ) -> Self

fn ignore_character(&self, chr: char) -> bool

Code points that will always be replaced by the replacement character.

See also invisible_char.

fn characters(&self) -> impl Iterator<Item = char> + '_

An un-ordered iterator over all supported characters.

fn glyph_info(&self, c: char) -> Option<GlyphInfo>

\n will result in None

pub fn pair_kerning(&self, last_glyph_id: GlyphId, glyph_id: GlyphId) -> f32

pub fn row_height(&self) -> f32

Height of one row of text in points.

pub fn pixels_per_point(&self) -> f32

pub fn ascent(&self) -> f32

This is the distance from the top to the baseline.

Unit: points.

fn allocate_glyph(&self, glyph_id: GlyphId) -> GlyphInfo
