Decompress a file with a specific algorithm.
using FileStream source = new("input.dat", FileMode.Open, FileAccess.Read, FileShare.Read);
using FileStream destination = new("output.dat", FileMode.Create, FileAccess.ReadWrite, FileShare.None);
new LZSS().Decompress(source, destination);Compress a file with a specific algorithm.
using FileStream source = new("input.dat", FileMode.Open, FileAccess.Read, FileShare.Read);
using FileStream destination = new("output.dat", FileMode.Create, FileAccess.ReadWrite, FileShare.None);
new LZSS().Compress(source, destination);Check if the file can be decompressed with a specific algorithm.
using FileStream source = new("input.dat", FileMode.Open, FileAccess.Read, FileShare.Read);
bool canDecompressed = new LZSS().IsMatch(source);- Nickworonekin Puyo Tools inspired the LZ Decode and Encode code and reference for CNX2, LZ00, LZ01, LZ10, LZ11, PRS algorithms.
