Struct ttf_parser::hmtx::Table
source · [−]pub struct Table<'a> {
pub metrics: LazyArray16<'a, Metrics>,
pub bearings: LazyArray16<'a, i16>,
pub number_of_metrics: u16,
}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: u16Sum of long metrics + bearings.
Implementations

impl<'a> Table<'a>
sourcepub fn parse(
number_of_metrics: u16,
number_of_glyphs: NonZeroU16,
data: &'a [u8]
) -> Option<Self>
pub fn parse(
number_of_metrics: u16,
number_of_glyphs: NonZeroU16,
data: &'a [u8]
) -> Option<Self>
Parses a table from raw data.
number_of_metricsis from thehhea/vheatable.number_of_glyphsis from themaxptable.
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.
