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.

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.
