Struct OutlineGlyphCollection

pub struct OutlineGlyphCollection<'a> { /* private fields */ }

Collection of scalable glyph outlines.

Implementations

impl<'a> OutlineGlyphCollection<'a>

pub fn new(font: &FontRef<'a>) -> Self

Creates a new outline collection for the given font.

pub fn with_format( font: &FontRef<'a>, format: OutlineGlyphFormat, ) -> Option<Self>

Creates a new outline collection for the given font and outline format.

Returns None if the font does not contain outlines in the requested format.

pub fn format(&self) -> Option<OutlineGlyphFormat>

Returns the underlying format of the source outline tables.

pub fn get(&self, glyph_id: GlyphId) -> Option<OutlineGlyph<'a>>

Returns the outline for the given glyph identifier.

pub fn iter( &self, ) -> impl Iterator<Item = (GlyphId, OutlineGlyph<'a>)> + 'a + Clone

Returns an iterator over all of the outline glyphs in the collection.

pub fn prefer_interpreter(&self) -> bool

Returns true if the interpreter engine should be used for hinting this set of outlines.

When this returns false, you likely want to use the automatic hinter instead.

This matches the logic used in FreeType when neither of the FT_LOAD_FORCE_AUTOHINT or FT_LOAD_NO_AUTOHINT load flags are specified.

When setting HintingOptions::engine to Engine::AutoFallback, this is used to determine whether to use the interpreter or automatic hinter.

Trait Implementations

impl<'a> Clone for OutlineGlyphCollection<'a>

fn clone(&self) -> OutlineGlyphCollection<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for OutlineGlyphCollection<'a>

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