An implementation of QOI Image Format with an encoder and a decoder. QOI is an O(n) single pass lossless image compression algorithm which is 20-50x faster than PNG with comparable compression ratio.
- Author has upload the original 1 page spec at https://qoiformat.org/qoi-specification.pdf.
- I have implemented a version with a 14 bit hash in
qoi_large_hash.cpp
. Seems to be slightly better.
- Add some benchmarks.
- Experiment with hash function.
