Home > DEFLATE (algorithm)
DEFLATE 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 widely thought to be free of any subsisting patents, and at a time before the patent on LZW (which is used in the GIF file format) expired, this has led to its use in gzip compressed files and PNG image files, in addition to the zip 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.
AdvanceCOMP implements a deflate implementation which allows to recompress Gzip, PNG, MNGMNG (pronounced ming is a public file format for animated images. The name stands for Multiple-image Network Graphics''. MNG is closely related to the PNG image format. When PNG development started in early 1995, developers decided not to incorporate supp and ZIPZIP is an abbreviation of: zoning improvement plan, better known as ZIP code zig-zag in-line package, a type of electronic packaging Zone Information Protocol implementation of an OSI model layer Zooming Interface Paradigm, an alternate computer interface to obtain smaller files than with the usual zlib one.
