Implementations

impl<'a> GlyphMetrics<'a>

pub fn units_per_em(&self) -> u16

Returns the number of font design units per em unit.

pub fn glyph_count(&self) -> u16

Returns the number of glyphs in the font.

pub fn has_vertical_metrics(&self) -> bool

Returns true if the font provides canonical vertical glyph metrics.

pub fn has_variations(&self) -> bool

Returns true if variations are supported.

pub fn scale(&self, ppem: f32) -> Self

Creates a new set of metrics scaled for the specified pixels per em unit.

pub fn linear_scale(&self, scale: f32) -> Self

Creates a new set of metrics scaled by the specified factor.

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

Returns the horizontal advance for the specified glyph.

pub fn lsb(&self, glyph_id: GlyphId) -> f32

Returns the left side bearing for the specified glyph.
