Struct ShaperInstance

pub struct ShaperInstance { /* private fields */ }

An instance of a variable font.

Implementations

impl ShaperInstance

pub fn from_variations<V>(font: &FontRef<'_>, variations: V) -> Self

where V: IntoIterator, V::Item: Into<Variation>,

Creates a new shaper instance for the given font from the specified list of variation settings.

The setting values are in user space and the order is insignificant.

pub fn from_coords( font: &FontRef<'_>, coords: impl IntoIterator<Item = NormalizedCoord>, ) -> Self

Creates a new shaper instance for the given font from the specified set of normalized coordinates.

The sequence of coordinates is expected to be in axis order.

pub fn from_named_instance(font: &FontRef<'_>, index: usize) -> Self

Creates a new shaper instance for the given font using the variation position from the named instance at the specified index.

pub fn coords(&self) -> &[F2Dot14]

Returns the underlying set of normalized coordinates.

pub fn set_variations<V>(&mut self, font: &FontRef<'_>, variations: V)

where V: IntoIterator, V::Item: Into<Variation>,

Resets the instance for the given font and variation settings.

pub fn set_coords( &mut self, font: &FontRef<'_>, coords: impl IntoIterator<Item = F2Dot14>, )

Resets the instance for the given font and normalized coordinates.

pub fn set_named_instance(&mut self, font: &FontRef<'_>, index: usize)

Resets the instance for the given font using the variation position from the named instance at the specified index.
