LzmaSettings

Class

Configures LZMA compression parameters (dictionary, context, position, fast bytes, match finder) for fine‑grained ratio and performance tuning.

Definition

Assembly:Telerik.Windows.Zip.dll

Syntax:

public class LzmaSettings : CompressionSettings, INotifyPropertyChanged

Creates an LZMA settings instance with defaults optimized for balanced speed and compression (8MB dictionary, BT4 match finder).

public LzmaSettings()

Gets or sets the base-2 exponent for the dictionary size (0–27), controlling memory usage; 23 (8MB) by default.

public int DictionarySize { get; set; }

Gets or sets the number of fast bytes (5–273) scanned for matches before fallback; higher may improve ratio but costs speed (default 32).

public int FastBytes { get; set; }

Gets or sets literal context bits (0–8) influencing prediction based on preceding bytes; default is 3.

public int LiteralContextBits { get; set; }

Gets or sets literal position bits (0–4) refining modeling by low address bits; default is 0.

public int LiteralPositionBits { get; set; }

Gets or sets the match finder algorithm variant determining hash granularity.

public LzmaMatchFinderType MatchFinderType { get; set; }

Gets or sets the number of position state bits (0–4) affecting literal/match modeling; default is 2.

public int PositionStateBits { get; set; }

Gets or sets the known uncompressed length for single standalone streams (not ZIP); -1 forces end marker emission.

public long StreamLength { get; set; }
