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.
