DotFastLZ.Compression 2023.10.1

Introduction

• DotFastLZ is a C# port of ariya/FastLZ
• DotFastLZ can be used in C# projects and Unity3D, and it's great for compressing small, repetitive data.

Usage: FastLZ

for (int level = 1; level <= 2; ++level)
{
    // compress
    var input = GetInputSource();
    var estimateSize = FastLZ.EstimateCompressedSize(input.Length);
    var comBuf = new byte[estimateSize];
    var comBufSize = FastLZ.CompressLevel(level, input, input.Length, comBuf);

    // decompress
    byte[] decBuf = new byte[input.Length];
    var decBufSize = FastLZ.Decompress(comBuf, comBufSize, decBuf, decBuf.Length);

    // compare
    var compareSize = FastLZ.MemCompare(input, 0, decBuf, 0, decBufSize);

    // check
    Assert.That(decBufSize, Is.EqualTo(input.Length), "decompress size error");
    Assert.That(compareSize, Is.EqualTo(input.Length), "decompress compare error");
}

Usage: 6pack
