Use the value DEFAULT_STRATEGY for normal + data, FILTERED for data produced by a filter (or + predictor), HUFFMAN_ONLY to force Huffman encoding only + (no string match), or RLE to limit match distances to one + (run-length encoding). 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 somewhat + intermediate between DEFAULT_STRATEGY and HUFFMAN_ONLY. + RLE is designed to be almost as fast as HUFFMAN_ONLY, but + give better compression for PNG image data.
