Struct FontAt 

pub(crate) struct FontAt<'a> {
    pub(crate) context: GlyfContext<'a>,
    pub(crate) coords: &'a [F2Dot14],
}

A font read at a location other than its own.

A VARC component defines its own coordinates, so its glyph is loaded through this type rather than the font. The font’s cached scalars only apply to its own location, so this type does not provide them.

Fields

context: GlyfContext<'a>

coords: &'a [F2Dot14]

Trait Implementations

impl<'a> Clone for FontAt<'a>

fn clone(&self) -> FontAt<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Copy for FontAt<'a>

impl<'a> OutlineContext<'a> for FontAt<'a>

fn glyph(&self, glyph: GlyphId) -> Option<LocaGlyph<'a>>

Returns the glyph with the given identifier, or None if it is empty.

fn glyph_variation_data(&self, glyph: GlyphId) -> Option<GlyphVariationData<'a>>

Variation data for a glyph, or None if the font does not vary or the glyph has none.

fn has_gvar(&self) -> bool

True if the font has a gvar table, whatever any one glyph has in it.

fn phantom_point_deltas(&self, glyph: GlyphId) -> Option<[Point<Fixed>; 4]>

Variation deltas for a glyph’s four phantom points.

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

Normalized variation coordinates, empty for the default instance.

fn units_per_em(&self) -> u16

Design units per em.

fn h_metrics(&self, glyph: GlyphId) -> (i32, i32)

Left side bearing and advance width, in font units.

fn v_metrics(&self, glyph: GlyphId) -> Option<(i32, i32)>

Top side bearing and vertical advance for a glyph, in font units.

fn h_line_metrics(&self) -> (i32, i32)

The ascender and descender of the line horizontal text sits on, in font units.

fn has_hvar(&self) -> bool

True if the font has an HVAR table.

fn gvar_scalars(&self) -> &[Fixed]

Scalars for gvar’s shared tuples at Self::coords, as SelectedGvar::compute_scalars fills them.
