Enum CompressionStrategy

Describes options for how the compression algorithm is executed. Different strategies work better on different sorts of data. The strategy parameter can affect the compression ratio and the speed of compression but not the correctness of the compresssion.

Syntax
public enum CompressionStrategy

Fields

Name Description
Default

The default strategy is probably the best for normal data.

Filtered

The Filtered strategy is intended to be used most effectively with data produced by a filter or predictor. By this definition, filtered data consists mostly of small values with a somewhat random distribution. In this case, the compression algorithm is tuned to compress them better. The effect of Filtered is to force more Huffman coding and less string matching; it is a half-step between Default and HuffmanOnly.

HuffmanOnly

Using HuffmanOnly will force the compressor to do Huffman encoding only, with no string matching.
