Crate ab_glyph

API for loading, scaling, positioning and rasterizing OpenType font glyphs.

Example

use ab_glyph::{point, Font, FontRef, Glyph};

let font = FontRef::try_from_slice(include_bytes!("../../dev/fonts/Exo2-Light.otf"))?;

// Get a glyph for 'q' with a scale & position.
let q_glyph: Glyph = font
    .glyph_id('q')
    .with_scale_and_position(24.0, point(100.0, 0.0));

// Draw it.
if let Some(q) = font.outline_glyph(q_glyph) {
    q.draw(|x, y, c| { /* draw pixel `(x, y)` with coverage: `c` */ });
}

Structs

CodepointIdIter

FontArc

Font implementor that wraps another concrete Font + 'static type storing in an Arc.

FontRef

Font data handle stored as a &[u8] + parsed data. See Font for more methods.

FontVec

Font data handle stored in a Vec<u8> + parsed data. See Font for more methods.

Glyph

A glyph with pixel scale & position.

GlyphId

Glyph id.

GlyphImageDeprecated

Old version of v2::GlyphImage.

GlyphSvg

InvalidFont

Invalid font data error.

Outline

A “raw” collection of outline curves for a glyph, unscaled & unpositioned.

OutlinedGlyph

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

Point

An (x, y) coordinate.

PxScale

Pixel scale.

PxScaleFactor

2D scale factors for use with unscaled metrics.

PxScaleFont

A Font and an associated pixel scale.

Rect

A rectangle, with top-left corner at min, and bottom-right corner at max.

VariationAxis

Enums

GlyphImageFormat

Valid formats for a GlyphImage.

OutlineCurve

Glyph outline primitives.

Traits

Font

Functionality required from font data.

ScaleFont

A Font with an associated pixel scale. This can be used to provide pixel scale values for glyph advances, heights etc.

VariableFont

Logic for variable fonts.

Functions

point

Point constructor.
