Struct ttf_parser::kern::Subtable

pub struct Subtable<'a> { /* fields omitted */ }

[−] Expand description

A kerning subtable.

Implementations

impl<'a> Subtable<'a>[−]

pub fn is_horizontal(&self) -> bool[−]

Checks that subtable is for horizontal text.

pub fn is_variable(&self) -> bool[−]

Checks that subtable is variable.

pub fn has_cross_stream(&self) -> bool[−]

Checks that subtable has a cross-stream values.

pub fn has_state_machine(&self) -> bool[−]

Checks that subtable uses a state machine.

In this case glyphs_kerning() will return None and you have to use state_machine() instead.

pub fn glyphs_kerning(&self, left: GlyphId, right: GlyphId) -> Option<i16>[−]

Returns kerning for a pair of glyphs.

Returns None in case of state machine based subtable.

pub fn state_machine(&self) -> Option<Machine<'_>>[−]

Returns subtable’s state machine if there is one.
