Implementations§

source§

impl<'a> Table<'a>

source

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

Parses a table from raw data.

source

pub fn has_glyph_classes(&self) -> bool

Checks that face has Glyph Class Definition Table.

source

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.

source

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.

source

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.

source

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.
