    Deflate Algorithm

    From Network Dictionary Wiki

    Jump to: navigation, search

    Deflate Algorithm is a lossless data compression algorithm that uses a combination of the LZ77 algorithm and Huffman coding. It was originally defined by Phil Katz for version 2 of his PKZIP archiving tool, and was later specified in RFC 1951. Deflate is used in gzip compressed files and PNG image files, in addition to the ZIP file format for which Katz originally designed it. Source code for Deflate compression and decompression can be found in zlib, the freely available, general-purpose compression library.
