Implementations

impl Font

pub fn parse(data: &'static [u8]) -> Option<Font>

font_register’s parse: None when the data is not SGF1

pub fn new(data: &'static [u8]) -> Font

pub fn hdr(&self) -> Hdr

pub fn lookup(&self, cp: u32) -> Option<u32>

binary search over the ranges {u32 firstCp, u16 count, u16 firstGlyph} [font_lookup]

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

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

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

kern(l, r) = matrix[lclass[l] * kernR + rclass[r]] * 4 font units

pub fn glyph_box(&self, g: u32) -> Option<[i32; 4]>

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

glyph_path: append the outline transformed by gp (implied on-curve midpoints, composites recursively)

pub fn outline(&self, g: u32, dx: i32, dy: i32, depth: u32, ol: &mut Outline)

append glyph g (composites resolved) to the outline buffer: points in font units + (dx, dy), one contour per SGF1 contour [sgf_outline]
