Implementations

impl ColorGlyphs

pub fn empty() -> Self

No color glyphs.

pub fn load(font: &RawFace<'_>) -> Result<Self>

Load the table, if present in the font.

pub fn glyph(&self, base_glyph: GlyphIndex) -> Option<ColorGlyph<'_>>

Iterate over color glyphs that replace the base_glyph to render in color.

The base_glyph is the glyph selected by the font during shaping.

Returns an iterator that renders an Emoji by overlaying colored glyphs, from the back (first item) to the front (last item). Paired with each glyph is an index in the font’s ColorPalette::colors or None if the base text color must be used.

Yields the base_glyph with no palette color if the font does not provide colored replacements for it.

pub fn is_empty(&self) -> bool

If the font does not have any colored glyphs.

pub fn len(&self) -> usize

Number of base glyphs that have colored replacements.
