Struct GlyphMetrics

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

Glyph specific metrics.

Implementations

impl<'a> GlyphMetrics<'a>

pub fn new( font: &impl TableProvider<'a>, size: Size, location: impl Into<LocationRef<'a>>, ) -> Self

Creates new glyph metrics from the given font, size, and location in normalized variation space.

pub fn glyph_count(&self) -> u32

Returns the number of available glyphs in the font.

pub fn advance_width(&self, glyph_id: GlyphId) -> Option<f32>

Returns the advance width for the specified glyph.

If normalized coordinates were provided when constructing glyph metrics and an HVAR table is present, applies the appropriate delta.

Returns None if glyph_id >= self.glyph_count() or the underlying font data is invalid.

pub fn left_side_bearing(&self, glyph_id: GlyphId) -> Option<f32>

Returns the left side bearing for the specified glyph.

If normalized coordinates were provided when constructing glyph metrics and an HVAR table is present, applies the appropriate delta.

Returns None if glyph_id >= self.glyph_count() or the underlying font data is invalid.

pub fn bounds(&self, glyph_id: GlyphId) -> Option<BoundingBox>

Returns the bounding box for the specified glyph.

Note that variations are not reflected in the bounding box returned by this method.

Returns None if glyph_id >= self.glyph_count(), the underlying font data is invalid, or the font does not contain TrueType outlines.

Trait Implementations

impl<'a> Clone for GlyphMetrics<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.
