pub type Hmtx<'a> = TableRef<'a, HmtxMarker>;

The hmtx (Horizontal Metrics) table

Aliased Type

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

Implementations

impl<'a> Hmtx<'a>

pub fn read( data: FontData<'a>, number_of_h_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> Hmtx<'a>

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

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

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

Leading (left/top) side bearings for glyph IDs greater than or equal to numberOfLongMetrics.

impl<'a> Hmtx<'a>

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

Returns the advance width for the given glyph identifier.

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

Returns the left side bearing for the given glyph identifier.

Trait Implementations

impl<'a> Debug for Hmtx<'a>

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

Formats the value using the given formatter.

impl<'a> FontReadWithArgs<'a> for Hmtx<'a>

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

read an item, using the provided args.

impl ReadArgs for Hmtx<'_>

type Args = (u16, u16)

impl<'a> SomeTable<'a> for Hmtx<'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.
