Struct HintState

pub(crate) struct HintState {
    scale: Fixed,
    blue_scale: Fixed,
    blue_shift: Fixed,
    blue_fuzz: Fixed,
    language_group: i32,
    suppress_overshoot: bool,
    do_em_box_hints: bool,
    boost: Fixed,
    darken_y: Fixed,
    zones: [BlueZone; 12],
    zone_count: usize,
}

Hinting state for a PostScript subfont.

Note that hinter states depend on the scale, subfont index and variation coordinates of a glyph. They can be retained and reused if those values remain the same.

Fields

scale: Fixed

blue_scale: Fixed

blue_shift: Fixed

blue_fuzz: Fixed

language_group: i32

suppress_overshoot: bool

do_em_box_hints: bool

boost: Fixed

darken_y: Fixed

zones: [BlueZone; 12]

zone_count: usize

Implementations

impl HintState

pub fn new(params: &HintParams, scale: Fixed) -> Self

fn zones(&self) -> &[BlueZone]

fn build_zones(&mut self, params: &HintParams)

Initialize zones from the set of blues values.

See https://gitlab.freedesktop.org/freetype/freetype/-/blob/80a507a6b8e3d2906ad2c8ba69329bd2fb2a85ef/src/psaux/psblues.c#L66

fn capture(&self, bottom_edge: &mut Hint, top_edge: &mut Hint) -> bool

Check whether a hint is captured by one of the blue zones.

Trait Implementations

impl Clone for HintState

fn clone(&self) -> HintState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for HintState

fn default() -> HintState

Returns the “default value” for a type.

impl PartialEq for HintState

fn eq(&self, other: &HintState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for HintState
