farbfeld

farbfeld is a lossless image format which is easy to parse, pipe and
compress.
It has the following format:

| Bytes | Description |
|--------|------------------------------------------------------------|
| 8 | "farbfeld" magic value |
| 4 | 32-Bit BE unsigned integer (width) |
| 4 | 32-Bit BE unsigned integer (height) |
| [2222] | 4⋅16-Bit BE unsigned integers [RGBA] / pixel, row-aligned |

Why in all the fuck are people using C for core libraries like this? That's the stupidest decision in the universe. Get away from C, all this basic overflow security shit goes away. (Yes, other high level data leaks are still possible.)

But in any case, there are PNG implementations. It's not hard to write your own to the spec. Other languages have it built in. It's a good file format and does everything farbfeld does but with better compression.
