Deflate algorithm explained
WebApr 9, 2011 · There are lots of implementations of the Deflate decompression algorithm in different languages. The decompression algorithm itself is described in RFC1951. However, the compression algorithm seems more elusive and I've only ever seen it implemented in long C/C++ files.. I'd like to find an implementation of the compression … Webdeflate. (file format, compression) A compression standard derived from LZ77; it is reportedly used in zip, gzip, PKZIP , and png, among others. Unlike LZW, deflate compression does not use patented compression algorithms. Used as a verb to mean to compress (not decompress!) a file which has been compressed using deflate compression.
