Struct ColorGlyphs 

pub struct ColorGlyphs<'a> {
    font: &'a Font,
    tables: Option<&'a ColrTables<'a>>,
}

Provides access to the color glyphs in a font.

Glyphs are painted at the location of the font. This type is cheap to create and copy because it borrows tables that the font has already parsed.

Fields

font: &'a Font

tables: Option<&'a ColrTables<'a>>

Implementations

impl<'a> ColorGlyphs<'a>

pub(crate) fn new(font: &'a Font) -> Self

pub fn font(&self) -> &'a Font

Returns the font that contains these glyphs.

pub fn is_empty(&self) -> bool

Returns true if the font has no COLR table.

pub fn version(&self) -> Option<u16>

Returns the version of the COLR table, or None if the font has no COLR table.

pub fn get_with_version( &self, glyph: GlyphId, version: ColorGlyphVersion, ) -> Option<ColorGlyph<'a>>

Returns the color glyph for glyph painted with the given version of COLR, if the table has one.

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

Returns the color glyph for glyph.

Uses version 1 of the table if it has the glyph, and version 0 otherwise.

pub(crate) fn extents( &self, glyph: GlyphId, outlines: OutlineGlyphs<'a>, ) -> Option<GlyphExtents<f32>>

Returns the ink bounds of glyph in font units, measured as HarfBuzz measures a color glyph.

Uses the clip box of a version 1 glyph if it has one. Otherwise the glyph is painted, from either version, and its fills are measured. Returns None if the table has no color glyph for glyph or painting it fails. A fill clipped to an outline measures the outline in outlines.

fn instance(&self) -> Option<ColrInstance<'a>>

Trait Implementations

impl<'a> Clone for ColorGlyphs<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.
