For now it's either 8- or 16-bit RGBA, adding more output formats adds complexity and requires more test cases. What's your use case for a 3-byte layout?

No, the letters are spelled out, the "s" stands for simple.

libspng doesn't support encoding images yet, the benchmarks show decode time. It is faster at decoding because it minimizes its per-pixel overhead, e.g. if a PNG image is has an RGBA 8-bit layout and it matches the requested output for

libpng compresses the image rows multiple times with different filters to optimize for size, this filtering process is not optimized. The choice of zlib also makes a big difference, stock zlib is very slow, zlib-ng is the closest to a fast

It would make the source file ~6k actual lines once the encoder and other features are added, but I see your point.

If you look at that crate's issue tracker you can see open issues titled "Crash on malformed input", "4-bit grayscale image is read as 8-bit", I don't think it's safer or even tested to be correct. For spn
