Expand description

A kerning subtable.

Fields§

§horizontal: bool

Indicates that subtable is for horizontal text.

§variable: bool

Indicates that subtable is variable.

§has_cross_stream: bool

Indicates that subtable has a cross-stream values.

§has_state_machine: bool

Indicates that subtable uses a state machine.

In this case glyphs_kerning() will return None.

§format: Format<'a>

Subtable format.

Implementations§

source§

impl<'a> Subtable<'a>

source

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

Returns kerning for a pair of glyphs.
