 ## Compression of images
 - I tested [FLIF](https://flif.info/) compression on ~200 MB file. Compression ratio was good but the speed on the other hand was really bad. Decompression wasn't better, it was slow too.
   - Even lossy compression was slow. This compression is probably only good for small images.
-- Next step is to test B3D compression.
+- **Next step is to test B3D compression.**
+- Pure LZW creates dictionary as it goes. Can create entries which aren't found in data.
+- LZ77 is better variant.
+- **Look at Huffman encoding, then maybe Arithmetic and in a spare time install nVidia drivers to test ot B3D library.**
