| Goal | Method | |------|--------| | | Embed font as static const data | | No heap | Use fixed arrays, avoid malloc | | No floating point | Use fixed‑point arithmetic (e.g., scale factor = 1000) | | Minimal dependencies | Only need line()/pixel() primitive | | Endian‑agnostic | Store as uint8_t arrays |
: CAG systems ensure that metrics like x-height, ascender height, and character width remain uniform across thousands of generated glyphs. 2. The Challenge of Portability
Portable versions typically load fonts into memory temporarily, making them ideal for users without administrator privileges on workstations.
