Struct Tuple Variation Header &nbsp; Copy item path

impl<'data> TupleVariationHeader<'data, Gvar>

pub fn variation_data<'a>( &'a self, num_points: NumPoints, shared_point_numbers: Option<SharedPointNumbers<'a>>, ) -> Result<GvarVariationData<'a>, ParseError>

Read the variation data for gvar.

num_points is the number of points in the glyph this variation relates to.

pub fn tuple_index(&self) -> Option<u16>

Returns the index of the shared tuple that this header relates to.

The tuple index is an index into the shared tuples of the Gvar table. Pass this value to the shared_tuple method to retrieve the tuple.

The value returned from this method will be None if the header has an embedded peak tuple.

pub fn peak_tuple<'a>( &'a self, gvar: &'a GvarTable<'data>, ) -> Result<ReadTuple<'data>, ParseError>

Returns the peak tuple for this tuple variation record.

If the record contains an embedded peak tuple then that is returned, otherwise the referenced shared peak tuple is returned.

impl<'data> TupleVariationHeader<'data, Cvar>

pub fn peak_tuple(&self) -> Option<ReadTuple<'data>>

Returns the embedded peak tuple if present.

The peak tuple is meant to always be present in cvar tuple variations, so None indicates an invalid font.

impl<'data, T> TupleVariationHeader<'data, T>

pub fn intermediate_region( &self, ) -> Option<(ReadTuple<'data>, ReadTuple<'data>)>

Returns the intermediate region of the tuple variation space that this variation applies to.

If an intermediate region is not specified (the region is implied by the peak tuple) then this will be None.
