Struct ab_glyph::OutlinedGlyph

pub struct OutlinedGlyph { /* private fields */ }

A glyph that has been outlined at a scale & position.

Implementations

impl OutlinedGlyph

pub fn new(glyph: Glyph, outline: Outline, scale_factor: PxScaleFactor) -> Self

Constructs an OutlinedGlyph from the source Glyph, pixel bounds & relatively positioned outline curves.

pub fn glyph(&self) -> &Glyph

Glyph info.

pub fn px_bounds(&self) -> Rect

Conservative whole number pixel bounding box for this glyph.

pub fn draw<O: FnMut(u32, u32, f32)>(&self, o: O)

Draw this glyph outline using a pixel & coverage handling function.

The callback will be called for each (x, y) pixel coordinate inside the bounds with a coverage value indicating how much the glyph covered that pixel.

A coverage value of 0.0 means the pixel is totally uncoverred by the glyph. A value of 1.0 or greater means fully coverred.
