LzmaSettings()
Creates an LZMA settings instance with defaults optimized for balanced speed and compression (8MB dictionary, BT4 match finder).
Declaration
public LzmaSettings()Properties
DictionarySize
Gets or sets the base-2 exponent for the dictionary size (0–27), controlling memory usage; 23 (8MB) by default.
FastBytes
Gets or sets the number of fast bytes (5–273) scanned for matches before fallback; higher may improve ratio but costs speed (default 32).
LiteralContextBits
Gets or sets literal context bits (0–8) influencing prediction based on preceding bytes; default is 3.
LiteralPositionBits
Gets or sets literal position bits (0–4) refining modeling by low address bits; default is 0.
MatchFinderType
Gets or sets the match finder algorithm variant determining hash granularity.
Declaration
public LzmaMatchFinderType MatchFinderType { get; set; }Property Value
PositionStateBits
Gets or sets the number of position state bits (0–4) affecting literal/match modeling; default is 2.
StreamLength
Gets or sets the known uncompressed length for single standalone streams (not ZIP); -1 forces end marker emission.
