Implementations§

Source §

impl FvarTable<'_>

Source

pub fn axes(&self) -> impl Iterator<Item = VariationAxisRecord> + '_

Returns an iterator over the variation axes of the font.

Source

pub fn axis_count(&self) -> u16

Returns the number of variation axes in the font.

Source

pub fn instances( &self, ) -> impl Iterator<Item = Result<InstanceRecord<'_>, ParseError>> + '_

Returns an iterator over the pre-defined instances in the font.

Source

pub fn normalize( &self, user_tuple: impl ExactSizeIterator<Item = Fixed>, avar: Option<&AvarTable<'_>>, ) -> Result<OwnedTuple, ParseError>

Turn a user tuple into a tuple normalized over the range -1..1.

Source

pub fn owned_tuple(&self, values: &[F2Dot14]) -> Option<OwnedTuple>

Construct a new OwnedTuple.

Returns None if the number of elements in values does not match axis_count.
