Struct AnchorFormat3 

pub struct AnchorFormat3<'a> {
    data: FontData<'a>,
}

Anchor Table Format 3: Design Units Plus Device or VariationIndex Tables

Fields

data: FontData<'a>

Implementations

impl<'a> AnchorFormat3<'a>

pub const MIN_SIZE: usize

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) -> &Self

👎Deprecated: just use the base type directly

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.

pub fn anchor_format(&self) -> u16

Format identifier, = 3

pub fn x_coordinate(&self) -> i16

Horizontal value, in design units

pub fn y_coordinate(&self) -> i16

Vertical value, in design units

pub fn x_device_offset(&self) -> Nullable<Offset16>

Offset to Device table (non-variable font) / VariationIndex table (variable font) for X coordinate, from beginning of Anchor table (may be NULL)

pub fn x_device(&self) -> Option<Result<DeviceOrVariationIndex<'a>, ReadError>>

Attempt to resolve x_device_offset.

pub fn y_device_offset(&self) -> Nullable<Offset16>

Offset to Device table (non-variable font) / VariationIndex table (variable font) for Y coordinate, from beginning of Anchor table (may be NULL)

pub fn y_device(&self) -> Option<Result<DeviceOrVariationIndex<'a>, ReadError>>

Attempt to resolve y_device_offset.

pub fn anchor_format_byte_range(&self) -> Range<usize>

pub fn x_coordinate_byte_range(&self) -> Range<usize>

pub fn y_coordinate_byte_range(&self) -> Range<usize>

pub fn x_device_offset_byte_range(&self) -> Range<usize>

pub fn y_device_offset_byte_range(&self) -> Range<usize>

Trait Implementations
