impl<'a> Colr<'a>

pub fn v0_base_glyph( &self, glyph_id: GlyphId, ) -> Result<Option<Range<usize>>, ReadError>

Returns the COLRv0 base glyph for the given glyph identifier.

The return value is a range of layer indices that can be passed to v0_layer to retrieve the layer glyph identifiers and palette color indices.

pub fn v0_layer(&self, index: usize) -> Result<(GlyphId16, u16), ReadError>

Returns the COLRv0 layer at the given index.

The layer is represented by a tuple containing the glyph identifier of the associated outline and the palette color index.

pub fn v1_base_glyph( &self, glyph_id: GlyphId, ) -> Result<Option<(Paint<'a>, PaintId)>, ReadError>

Returns the COLRv1 base glyph for the given glyph identifier.

The second value in the tuple is a unique identifier for the paint that may be used to detect recursion in the paint graph.

pub fn v1_layer(&self, index: usize) -> Result<(Paint<'a>, PaintId), ReadError>

Returns the COLRv1 layer at the given index.

The second value in the tuple is a unique identifier for the paint that may be used to detect recursion in the paint graph.

pub fn v1_clip_box( &self, glyph_id: GlyphId, ) -> Result<Option<ClipBox<'a>>, ReadError>

Returns the COLRv1 clip box for the given glyph identifier.
