Class LzmaArchiveSettings

Class LzmaArchiveSettings

Namespace: Aspose.Zip.LZMA
Assembly: Aspose.Zip.dll (25.2.0)

Settings for lzma archive.

public class LzmaArchiveSettings

Inheritance

object ← LzmaArchiveSettings

Inherited Members

object.GetType(), object.MemberwiseClone(), object.ToString(), object.Equals(object?), object.Equals(object?, object?), object.ReferenceEquals(object?, object?), object.GetHashCode()

Remarks

The Lempel–Ziv–Markov chain algorithm (LZMA) is an algorithm used to perform lossless data compression. This algorithm uses a dictionary compression scheme somewhat similar to the LZ77 algorithm and features a high compression ratio and a variable compression-dictionary size.

Constructors

LzmaArchiveSettings()

Initializes a new instance of the Aspose.Zip.LZMA.LzmaArchiveSettings class with default dictionary size, equals to 16 megabytes.

public LzmaArchiveSettings()

Examples 

using (LzmaArchive archive = new LzmaArchive(new LzmaArchiveSettings() { DictionarySize = 1048576 } )
{
    archive.SetSource("data.bin);
    archive.Save(lzmaFile);
}

Properties

DictionarySize

Dictionary (history buffer) size indicates how many bytes of the recently processed uncompressed data is kept in memory. If not set, will be chosen accordingly to entry size.

public int DictionarySize { get; set; }

Property Value

int

Remarks

The bigger the dictionary, the better the compression ratio usually is, but dictionaries bigger than the uncompressed data are waste of RAM.

CompressionProgressed

Raises when a portion of raw stream compressed.

public event EventHandler<progresseventargs> CompressionProgressed

Event Type

EventHandler<ProgressEventArgs&gt;

Examples

lzmaArchiveSettings.CompressionProgressed += (s, e) =&gt; { int percent = (int)((100 * (long)e.ProceededBytes) / entrySourceStream.Length); };
