pub type Vmtx<'a> = TableRef<'a, VmtxMarker>;

The vmtx (Vertical Metrics) table

Aliased Type

struct Vmtx<'a> { /* private fields */ }

Implementations

impl<'a> Vmtx<'a>

pub fn read( data: FontData<'a>, number_of_long_ver_metrics: u16, num_glyphs: u16 ) -> Result<Self, ReadError>

A constructor that requires additional arguments.

This type requires some external state in order to be parsed.

impl<'a> Vmtx<'a>

pub fn v_metrics(&self) -> &'a [LongMetric]

Paired advance height and top side bearing values for each glyph. Records are indexed by glyph ID.

pub fn top_side_bearings(&self) -> &'a [BigEndian<i16>]

Top side bearings for glyph IDs greater than or equal to numberOfLongMetrics.

impl<'a> Vmtx<'a>

pub fn advance(&self, glyph_id: GlyphId) -> Option<u16>

Returns the advance height for the given glyph identifier.

pub fn side_bearing(&self, glyph_id: GlyphId) -> Option<i16>

Returns the top side bearing for the given glyph identifer.

Trait Implementations

impl<'a> Debug for Vmtx<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> FontReadWithArgs<'a> for Vmtx<'a>

fn read_with_args( data: FontData<'a>, args: &(u16, u16) ) -> Result<Self, ReadError>

read an item, using the provided args.

impl ReadArgs for Vmtx<'_>

type Args = (u16, u16)

impl<'a> SomeTable<'a> for Vmtx<'a>

fn type_name(&self) -> &str

The name of this table

fn get_field(&self, idx: usize) -> Option<Field<'a>>

Access this table’s fields, in declaration order.

impl TopLevelTable for Vmtx<'_>

const TAG: Tag = _
