In computing, Deflate (stylized as DEFLATE) is a lossless data compression file format that uses a combination of LZ77 and Huffman coding. It was designed by Phil Katz, for version 2 of his PKZIP archiving tool. Deflate was later specified in RFC 1951 (1996). Katz also designed the original algorithm used to … See more A Deflate stream consists of a series of blocks. Each block is preceded by a 3-bit header: • First bit: Last-block-in-stream marker: • Second and third bits: Encoding method used for this block … See more Inflate is the decoding process that takes a Deflate bitstream for decompression and correctly produces the original full-size data or file. Inflate-only implementations The normal intent with an alternative Inflate … See more • PKWARE, Inc.'s appnote.txt, .ZIP File Format Specification Archived 2014-12-05 at the Wayback Machine; Section 10, X. Deflating – Method 8. See more During the compression stage, it is the encoder that chooses the amount of time spent looking for matching strings. The zlib/gzip reference implementation allows the user to select … See more Implementations of Deflate are freely available in many languages.
