Implementations§

source§

impl<'a> ShaperBuilder<'a>

source

pub fn script(self, script: Script) -> Self

Specifies the script. The default value is Script::Latin.

source

pub fn language(self, language: Option<Language>) -> Self

Specifies the language. The default value is None.

source

pub fn direction(self, direction: Direction) -> Self

Specifies the text direction. The default value is Direction::LeftToRight.

source

pub fn size(self, ppem: f32) -> Self

Specifies the font size in pixels per em. The default value is 0 which will produce glyphs with offsets and advances in font units.

source

pub fn features<I>(self, settings: I) -> Self
where I: IntoIterator, I::Item: Into<Setting<u16>>,

Adds feature settings to the shaper.

source

pub fn variations<I>(self, settings: I) -> Self
where I: IntoIterator, I::Item: Into<Setting<f32>>,

Adds variation settings to the shaper.

source

pub fn normalized_coords<I>(self, coords: I) -> Self

Specifies the variation settings in terms of normalized coordinates.

source

pub fn insert_dotted_circles(self, yes: bool) -> Self

Specifies whether to insert dotted circles for broken clusters. The default value is false.

source

pub fn retain_ignorables(self, yes: bool) -> Self

Specifies whether characters defined as default ignorable should be retained by the shaper. The default is false.

source

pub fn build(self) -> Shaper<'a>

Builds a shaper for the current configuration.
