Type Alias GlyphData

pub type GlyphData<'a> = TableRef<'a, GlyphDataMarker>;

Glyph data table

Aliased Type

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

Implementations

impl<'a> GlyphData<'a>

pub fn origin_offset_x(&self) -> i16

The horizontal (x-axis) position of the left edge of the bitmap graphic in relation to the glyph design space origin.

pub fn origin_offset_y(&self) -> i16

The vertical (y-axis) position of the bottom edge of the bitmap graphic in relation to the glyph design space origin.

pub fn graphic_type(&self) -> Tag

Indicates the format of the embedded graphic data: one of ’jpg ’, ’png ’ or ‘tiff’, or the special format ‘dupe’.

pub fn data(&self) -> &'a [u8]

The actual embedded graphic data. The total length is inferred from sequential entries in the glyphDataOffsets array and the fixed size (8 bytes) of the preceding fields.

impl<'a, T> TableRef<'a, T>

pub fn resolve_offset<O: Offset, R: FontRead<'a>>( &self, offset: O, ) -> Result<R, ReadError>

Resolve the provided offset from the start of this table.

pub fn offset_data(&self) -> FontData<'a>

Return a reference to this table’s raw data.

We use this in the compile crate to resolve offsets.

pub fn shape(&self) -> &T

Return a reference to the table’s ‘Shape’ struct.

This is a low level implementation detail, but it can be useful in some cases where you want to know things about a table’s layout, such as the byte offsets of specific fields.

Trait Implementations

impl<'a> FontRead<'a> for GlyphData<'a>

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

Read an instance of Self from the provided data, performing validation.

impl<'a, T: Clone> Clone for TableRef<'a, T>

fn clone(&self) -> TableRef<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.
