Implementations

impl TtFont

pub fn open( data: Vec<u8>, face: u32, ol: &mut Outline, serial: u64, ) -> Result<Box<TtFont>, i32>

ttf_open(data, face): the context, or ERR_*

pub fn glyph(&self, cp: u32) -> u32

glyph for cp (0 = .notdef). Symbol fonts ((3,0) cmap) map like GDI: U+0000..U+00FF and the Windows-1252 characters to U+F000 + their code page byte [ttf_glyph]

pub fn has(&self, cp: u32) -> bool

pub fn adv(&self, g: u32) -> i32

advance (hmtx; the last long metric repeats) [ttf_adv]

pub fn kern_table(&self, g1: u32, g2: u32) -> i32

sum of the ‘kern’ format 0 values [tt_kern_table]

pub fn kern(&self, g1: u32, g2: u32) -> i32

GPOS ‘kern’ when present, else ‘kern’ [ttf_kern]

pub fn name(&self, which: u32) -> &[u8]

font_name of this font (“” for an unknown id) [ttf_name]

pub fn prep(&self, glyph: u32, ol: &mut Outline) -> bool

the outline of glyph into the buffer (owner set either way): true = not empty [ttf_prep]

pub fn bbox(&self, g: u32, ol: &mut Outline) -> Option<[i32; 4]>

control box (font units) and the prepared outline [ttf_box]

pub fn path(&self, g: u32, ol: &mut Outline, path: &mut Path, gp: &Gp)

append the outline to the path with the gp transform [ttf_path]
