pub fn with_scale<S: Into<PxScale>>(self, scale: S) -> Self

Trait Implementations

impl<F: Clone> Clone for PxScaleFont<F>

fn clone(&self) -> PxScaleFont<F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<F: Debug> Debug for PxScaleFont<F>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<F: Font> ScaleFont<F> for PxScaleFont<F>

fn scale(&self) -> PxScale

Returns the pixel scale associated with this font.

fn font(&self) -> &F

Returns a font reference.

fn codepoint_ids(&self) -> CodepointIdIter<'_>

Returns an iterator of all distinct (GlyphId, char) pairs. Not ordered.

fn h_scale_factor(&self) -> f32

Scale factor for unscaled font horizontal values.

fn v_scale_factor(&self) -> f32

Scale factor for unscaled font vertical values.

fn scale_factor(&self) -> PxScaleFactor

fn ascent(&self) -> f32

Pixel scaled glyph ascent.

fn descent(&self) -> f32

Pixel scaled glyph descent.

fn height(&self) -> f32

Pixel scaled height ascent - descent.

fn line_gap(&self) -> f32

Pixel scaled line gap.

fn glyph_id(&self, c: char) -> GlyphId

Lookup a GlyphId matching a given char.

fn scaled_glyph(&self, c: char) -> Glyph

Construct a Glyph with the font’s pixel scale at position point(0.0, 0.0).

fn h_advance(&self, id: GlyphId) -> f32

Pixel scaled horizontal advance for a given glyph.

fn h_side_bearing(&self, id: GlyphId) -> f32

Pixel scaled horizontal side bearing for a given glyph.

fn v_advance(&self, id: GlyphId) -> f32

Pixel scaled vertical advance for a given glyph.

fn v_side_bearing(&self, id: GlyphId) -> f32

Pixel scaled vertical side bearing for a given glyph.

fn kern(&self, first: GlyphId, second: GlyphId) -> f32

Returns additional pixel scaled kerning to apply for a particular pair of glyphs.

fn glyph_bounds(&self, glyph: &Glyph) -> Rect

Returns the layout bounds of this glyph. These are different to the outline px_bounds().

fn glyph_count(&self) -> usize

The number of glyphs present in this font. Glyph identifiers for this font will always be in the range 0..self.glyph_count()

fn outline_glyph(&self, glyph: Glyph) -> Option<OutlinedGlyph>

Compute glyph outline ready for drawing.
