pixglyph
OpenType glyph rendering.
[dependencies]
pixglyph = "0.1"
Features
- Render glyph outlines into coverage bitmaps.
- Place glyphs at subpixel offsets and scale them to subpixel sizes. This is important if you plan to render more than a single glyph since inter-glyph spacing will look off if every glyph origin must be pixel-aligned.
- No font data structure you have to store somewhere. Just owned glyphs which you can load individually from a font, cache if you care about performance, and then render at any size.
- No unsafe code.

Note on text: This library does not provide any capabilities to map
text/characters to glyph ids. Instead, you should use a proper shaping
library (like rustybuzz
) to do this step. This will take care of proper
glyph positioning, ligatures and more.
Note on emojis: This library only supports normal outlines. How to best render bitmap, SVG and colored glyphs depends very much on your rendering environment.
