Struct Subfont

pub(crate) struct Subfont {
    is_cff2: bool,
    scale: Option<Fixed>,
    subrs_offset: Option<usize>,
    pub(crate) hint_state: HintState,
    store_index: u16,
}

Specifies local subroutines and hinting parameters for some subset of glyphs in a CFF or CFF2 table.

This type is designed to be cacheable to avoid re-evaluating the private dict every time a charstring is processed.

For variable fonts, this is dependent on a location in variation space.

Fields

is_cff2: bool

scale: Option<Fixed>

subrs_offset: Option<usize>

hint_state: HintState

store_index: u16

Implementations

impl Subfont

pub fn subrs<'a>( &self, scaler: &Outlines<'a>, ) -> Result<Option<Index<'a>>, Error>

Returns the local subroutine index.

pub fn blend_state<'a>( &self, scaler: &Outlines<'a>, coords: &'a [F2Dot14], ) -> Result<Option<BlendState<'a>>, Error>

Creates a new blend state for the given normalized variation coordinates.

Trait Implementations

impl Clone for Subfont

fn clone(&self) -> Subfont

Returns a duplicate of the value.

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

Performs copy-assignment from source.
