Expand description

gvar Glyph Variations Table

https://learn.microsoft.com/en-us/typography/opentype/spec/gvar#gvar-header

Fields§

§major_version: u16

Major version number of the glyph variations table.

§minor_version: u16

Minor version number of the glyph variations table.

§axis_count: u16

The number of variation axes for this font.

This must be the same number as axisCount in the ‘fvar’ table.

§glyph_count: u16

The number of glyphs in this font.

This must match the number of glyphs stored elsewhere in the font.

Implementations§

Source §

impl<'a> GvarTable<'a>

Source

pub fn glyph_variation_data( &self, glyph_index: u16, num_points: NumPoints, ) -> Result<Option<TupleVariationStore<'a, Gvar>>, ParseError>

Returns the variation data for the glyph at glyph_index that has num_points points (including and phantom points).

If the glyph has no variations, such as when the glyph is an empty glyph, then None is returned.

Source

pub fn shared_tuple(&self, index: u16) -> Result<ReadTuple<'a>, ParseError>

Returns the shared peak tuple at the supplied index.
