Struct ttf_parser::gdef::Table

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

A Glyph Definition Table.

Implementations

impl<'a> Table<'a>

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

Parses a table from raw data.

pub fn has_glyph_classes(&self) -> bool

Checks that face has Glyph Class Definition Table.

pub fn glyph_class(&self, glyph_id: GlyphId) -> Option<GlyphClass>

Returns glyph’s class according to Glyph Class Definition Table.

Returns None when Glyph Class Definition Table is not set or glyph class is not set or invalid.

pub fn glyph_mark_attachment_class(&self, glyph_id: GlyphId) -> Class

Returns glyph’s mark attachment class according to Mark Attachment Class Definition Table.

All glyphs not assigned to a class fall into Class 0.

pub fn is_mark_glyph(&self, glyph_id: GlyphId, set_index: Option<u16>) -> bool

Checks that glyph is a mark according to Mark Glyph Sets Table.

set_index allows checking a specific glyph coverage set. Otherwise all sets will be checked.

pub fn glyph_variation_delta( &self, outer_index: u16, inner_index: u16, coordinates: &[NormalizedCoordinate] ) -> Option<f32>

Returns glyph’s variation delta at a specified index according to Item Variation Store Table.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Default for Table<'a>

fn default() -> Table<'a>
