<!-- Please read the "Making a PR" section of [`CONTRIBUTING.md`](https://github.com/emilk/egui/blob/main/CONTRIBUTING.md) before opening a Pull Request! * Keep your PR:s small and focused. * The PR title is what ends up in the changelog, so make it descriptive! * If applicable, add a screenshot or gif. * If it is a non-trivial addition, consider adding a demo for it to `egui_demo_lib`, or a new example. * Do NOT open PR:s from your `master` branch, as that makes it hard for maintainers to test and add commits to your PR. * Remember to run `cargo fmt` and `cargo clippy`. * Open the PR as a draft until you have self-reviewed it and run `./scripts/check.sh`. * When you have addressed a PR comment, mark it as resolved. Please be patient! I will review your PR, but my time is limited! --> * Closes N/A * [x] I have followed the instructions in the PR template I'll probably come back to this and clean it up a bit. This PR reimplements ab_glyph's functionality on top of Skrifa, a somewhat lower-level font API that's being used in Chrome now. Skrifa doesn't perform rasterization itself, so I'm using [vello_cpu](https://github.com/linebender/vello) from the Linebender project for rasterization. It's still in its early days, but I believe it's already quite fast. It also supports color and gradient fills, so color emoji support will be easier. Skrifa also supports font hinting, which should make text look a bit nicer / less blurry. Here's the current ab_glyph rendering: <img width="1592" height="1068" alt="image" src="https://github.com/user-attachments/assets/2385b66e-23f8-4c6e-b8c2-ea90e0eea4e4" /> Here's Skrifa *without* hinting--it looks almost identical, but there are some subpixel differences, probably due to rasterizer behavior: <img width="1592" height="1068" alt="image" src="https://github.com/user-attachments/assets/a815f3e9-65ac-4940-bc00-571177bef53d" /> Here's Skrifa *with* hinting: <img width="1592" height="1068" alt="image" src="https://github.com/user-attachments/assets/d6cc0669-3537-4377-bba9-ed5ef09664db" /> Hinting does make the horizontal strokes look a bit bolder, which makes me wonder once again about increasing the font weight from "light" to "regular". --------- Co-authored-by: Emil Ernerfeldt <emil.ernerfeldt@gmail.com>
