Implementations

impl HintMap

fn new(scale: Fixed) -> Self

fn clear(&mut self)

fn transform(&self, coord: Fixed) -> Fixed

Transform character space coordinate to device space.

fn insert(&mut self, bottom: &Hint, top: &Hint, initial: Option<&HintMap>)

Insert hint edges into map, sorted by character space coordinate.

fn adjust(&mut self)

Adjust hint pairs so that one of the two edges is on a pixel boundary.

fn build( &mut self, state: &HintState, mask: Option<HintMask>, initial_map: Option<&mut HintMap>, stems: &mut [StemHint], origin: Fixed, is_initial: bool, )

Builds a hintmap from hints and mask.

If initial_map is invalid, this recurses one level to initialize it. If is_initial is true, simply build the initial map.
