War3Net.IO.Compression is a .NET library providing compression and decompression algorithms used in MPQ (MoPaQ) archives. It is part of the War3Net modding library for Warcraft III.

• Compress and decompress data using ZLib (DEFLATE)
• Decompress PKLib (PKWARE) compressed data
• Decompress Huffman encoded data
• Decompress BZip2 compressed data
• Decompress IMA ADPCM audio data (mono and stereo)

using War3Net.IO.Compression;

// Compress a stream
using var inputStream = File.OpenRead("input.dat");
using var compressedStream = ZLibCompression.Compress(inputStream, (int)inputStream.Length, leaveOpen: false);

// Write compressed data to file
using var outputStream = File.Create("output.dat");
compressedStream.Position = 0;
compressedStream.CopyTo(outputStream);

using War3Net.IO.Compression;

byte[] compressedData = GetCompressedData();
uint expectedLength = 1024; // Expected decompressed size

byte[] decompressedData = ZLibCompression.Decompress(compressedData, expectedLength);

using War3Net.IO.Compression;

byte[] compressedData = GetPKLibCompressedData();
uint expectedLength = 2048;

byte[] decompressedData = PKLibCompression.Decompress(compressedData, expectedLength);

using War3Net.IO.Compression;

byte[] compressedData = GetHuffmanCompressedData();

byte[] decompressedData = HuffmanCoding.Decompress(compressedData);

using War3Net.IO.Compression;

byte[] compressedAudio = GetADPCMCompressedAudio();
int channelCount = 2; // 1 for mono, 2 for stereo

byte[] decompressedAudio = AdpcmCompression.Decompress(compressedAudio, channelCount);

The main types provided by this library are:

• War3Net.IO.Compression.ZLibCompression - Compress and decompress using ZLib (DEFLATE)
• War3Net.IO.Compression.PKLibCompression - Decompress PKLib (PKWARE) compressed data
• War3Net.IO.Compression.HuffmanCoding - Decompress Huffman encoded data
• War3Net.IO.Compression.BZip2Compression - Decompress BZip2 compressed data
• War3Net.IO.Compression.AdpcmCompression - Decompress IMA ADPCM audio data

• War3Net.IO.Mpq - Read and write MPQ archives
• War3Net.Build - Generate JASS map scripts and compile maps
• War3Net.Build.Core - Parsers and serializers for war3map files

War3Net.IO.Compression is released as open source under the MIT license. Bug reports and contributions are welcome at the GitHub repository.
