Types

type Table

type Table map[glyph.ID]uint16

Table contains the information from an OpenType "Class Definition Table". All glyphs not assigned to a class fall into Class 0.

func Read

func Read(p *parser.Parser, pos int64) (Table, error)

Read reads and decodes an OpenType "Class Definition Table".

func (Table) Append

func (info Table) Append(buf []byte) []byte

Append appends the binary table representation to the given buffer.

func (Table) AppendLen

func (info Table) AppendLen() int

AppendLen returns the size of the binary table representation.

func (Table) Glyphs

func (info Table) Glyphs() [][]glyph.ID

Glyphs returns the glyphs for each non-zero class in the Table. The first entry of the returned slice, corresponding to class 0, is always nil.
