pub struct Lookup<'a> { /* private fields */ }

Expand description

A lookup table.

u32 values in Format10 tables will be truncated to u16. u64 values in Format10 tables are not supported.

Implementations§

source §

impl<'a> Lookup<'a>

source

pub fn parse(number_of_glyphs: NonZeroU16, data: &'a [u8]) -> Option<Self>

Parses a lookup table from raw data.

number_of_glyphs is from the maxp table.

source

pub fn value(&self, glyph_id: GlyphId) -> Option<u16>

Returns a value associated with the specified glyph.
