Methods

impl Font

pub fn from_bytes<Data: Deref<Target = [u8]>>(data: Data) -> FontResult<Font>

Constructs a font from an array of bytes.

pub fn metrics(&self, character: char, px: f32) -> Metrics

Retrieves the layout metrics for the given character. If the caracter isn't present in the font, then the layout for the font's default character is returned instead.

pub fn metrics_indexed(&self, index: usize, px: f32) -> Metrics

Retrieves the layout metrics at the given index. You normally want to be using metrics(char, f32) instead, unless your glyphs are pre-indexed.

pub fn rasterize(&mut self, character: char, px: f32) -> (Metrics, Vec<u8>)

Retrieves the layout metrics and rasterized bitmap for the given character. If the caracter isn't present in the font, then the layout and bitmap for the font's default character is returned instead.

pub fn rasterize_indexed(&mut self, index: usize, px: f32) -> (Metrics, Vec<u8>)

Retrieves the layout metrics and rasterized bitmap at the given index. You normally want to be using rasterize(char, f32) instead, unless your glyphs are pre-indexed.

pub fn lookup_glyph_index(&self, character: char) -> usize
