}
Expand description
A Horizontal/Vertical Metrics Table.
hmtx
and vmtx
tables has the same structure, so we’re reusing the same struct for both.
Fields§
§metrics: LazyArray16<'a, Metrics>
A list of metrics indexed by glyph ID.
bearings: LazyArray16<'a, i16>
Side bearings for glyph IDs greater than or equal to the number of metrics
values.
number_of_metrics: u16
Sum of long metrics + bearings.
Implementations§
source§impl<'a> Table<'a>
impl<'a> Table<'a>
sourcepub fn parse(
number_of_metrics: u16,
number_of_glyphs: NonZero<u16>,
data: &'a [u8],
) -> Option<Table<'a>>
pub fn parse( number_of_metrics: u16, number_of_glyphs: NonZero<u16>, data: &'a [u8], ) -> Option<Table<'a>>
Parses a table from raw data.
number_of_metrics
is from thehhea
/vhea
table.number_of_glyphs
is from themaxp
table.
sourcepub fn side_bearing(&self, glyph_id: GlyphId) -> Option<i16>
pub fn side_bearing(&self, glyph_id: GlyphId) -> Option<i16>
Returns side bearing for a glyph.
