/*
|

|
||||
Alright Fonts 🖍 - a font format for embedded and low resource platforms.
|
||||
|
||||
Jonathan Williamson, August 2022
|
||||
Examples, source, and more: https://github.com/lowfatcode/pretty-poly
|
||||
MIT License https://github.com/lowfatcode/pretty-poly/blob/main/LICENSE
|
||||
|
||||
An easy way to render high quality text in embedded applications running
|
||||
on resource constrained microcontrollers such as the Cortex M0 and up.
|
||||
|
||||
- OTF and TTF support: generate efficient packed fonts easily
|
||||
- Minimal data: ~4kB (40 bytes per char) for printable ASCII set (Roboto)
|
||||
- Tunable: trade off file size, contour complexity, and visual quality
|
||||
- Metrics: advance and bounding box for fast layout
|
||||
- UTF-8 or ASCII: support for non ASCII like Kanji or Cyrillic
|
||||
- Fixed scale: coords scaled to ^2 bounds for fast scaling (no divide)
|
||||
- C17 header only library: simply copy the header file into your project
|
||||
- Customised font packs: include only the characters you need
|
||||
- Simple outlines: all paths are simply polylines for easy rendering
|
||||
- Easy antialiasing: combine with Pretty Poly for quick results!
