Struct InstanceBuilder 

pub struct InstanceBuilder {
    font: SharedFont,
    coords: SmallVec<[NormalizedCoord; 12]>,
    type1_blend: SmallVec<[Fixed; 4]>,
}

Builder for configuring a font instance.

Fields

font: SharedFont

coords: SmallVec<[NormalizedCoord; 12]>

type1_blend: SmallVec<[Fixed; 4]>

The blend coordinates of a Type 1 multiple master location, which coords holds rounded to 2.14. The weights are computed from these.

Implementations

impl InstanceBuilder

pub fn variations<V>(self, variations: V) -> Self

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

Sets the variations for the font instance from an unordered sequence of variations in user space.

Omitted axes will be set to their default values. Unsupported axes are ignored. If an axis is specified multiple times, the last value is used.

This will overwrite any previous variation settings.

pub fn normalized_coords( self, coords: impl IntoIterator<Item = NormalizedCoord>, ) -> Self

Sets the variations for the font instance from an ordered sequence of normalized coordinates.

If the number of provided coordinates is less than the number of axes, the remaining axes will be set to their default values. If the number of provided coordinates is greater than the number of axes, the extra coordinates will be ignored.

This will overwrite any previous variation settings.

pub fn named_instance(self, index: u32) -> Self

Sets the variations for the font instance from a named instance.

If the given named instance index is invalid, then variation settings will be reset to default.

This will overwrite any previous variation settings.

pub fn named_instance_with_overrides<V>(self, index: u32, overrides: V) -> Self

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

Sets the variations for the font instance from a named instance, with additional overrides.

If the given named instance index is invalid, then it is ignored and only overrides are applied.

This will overwrite any previous variation settings.

pub fn build(self) -> Font

Builds the font instance.

impl InstanceBuilder

fn set_variations<V>(&mut self, variations: V)

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

fn set_coords(&mut self, coords: impl IntoIterator<Item = NormalizedCoord>)

fn set_type1_blend(&mut self, blend: SmallVec<[Fixed; 4]>)

Sets the location of a Type 1 multiple master font.

Every blend is kept, even all zeros, which is a master rather than the font’s default.

The weights are computed from blend itself. The coordinates are those the weights give back, which rounding in the weights can move from blend by the smallest step, as FreeType reports them.
