Implementations

impl<'a> Table<'a>

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

Parses a table from raw data.

pub fn number_of_glyphs(&self) -> u16

Returns a total number of glyphs in the font.

Never zero.

pub fn matrix(&self) -> Matrix

Returns a font transformation matrix.

pub fn outline( &self, glyph_id: GlyphId, builder: &mut dyn OutlineBuilder, ) -> Result<Rect, CFFError>

Outlines a glyph.

pub fn glyph_index(&self, code_point: u8) -> Option<GlyphId>

Resolves a Glyph ID for a code point.

Similar to Face::glyph_index but 8bit and uses CFF encoding and charset tables instead of TrueType cmap.

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

Returns a glyph width.

This value is different from outline bbox width and is stored separately.

Technically similar to Face::glyph_hor_advance.

pub fn glyph_index_by_name(&self, name: &str) -> Option<GlyphId>

Returns a glyph ID by a name.

pub fn glyph_name(&self, glyph_id: GlyphId) -> Option<&'a str>

Returns a glyph name.

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

Returns the CID corresponding to a glyph ID.

Returns None if this is not a CIDFont.

Trait Implementations

impl<'a> Clone for Table<'a>

fn clone(&self) -> Table<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Table<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
