Deutsch & Gailly Informational [Page 2] RFC 1950 ZLIB Compressed Data Format Specification May 1996 1.2. Intended audience This specification is intended for use by implementors of software to compress data into zlib format and/or decompress data from zlib format. The text of the specification ...
This specification defines a lossless compressed data format. The data can be produced or consumed, even for an arbitrarily long sequentially presented input data stream, using only an a priori bounded amount of intermediate storage. The format presently uses the DEFLATE compression method but can...
For compression method 8, the compressed data is stored in the deflate compressed data format as described in the document "DEFLATE Compressed Data Format Specification" by L. Peter Deutsch. (See reference [3] in Chapter 3, below) Other compressed data formats are not specified in this version...

compressed_data =zlib.compress(original_data)print(‘压缩的数据:长度 : {},内容 : {}‘.format(len(compressed_data), binascii.hexlify(compressed_data))) #binascii.hexlify主要作用是将字节类转为16进制显示 #解压数据 decompress_data =zlib.decompress(compressed_data)print(‘压缩的数据:长度 : {},...
zlib is designed to be a free, general-purpose, legally unencumbered -- that is, not covered by any patents -- lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms. ...
format added. 'QZ_DEFLATE_GZIP_EXT' data format need to add gz_header by deflateSetHeader() in QATzip. And it may lead multi stream in one compression because for hardware buffer. So the windows bit is important information for decompression, which related to ...
4.3.9 Data descriptor: crc-32 4 bytes compressed size 4 bytes uncompressed size 4 bytes 4.3.9.3 Although not originally assigned a signature, the value 0x08074b50 has commonly been adopted as a signature value 4bytes 头部共有31个,尾部有16个,因此需要去掉头尾 ...
gzip uses the Deflate compressed data format, which compresses quite a bit better than Unix compress, has very fast decompression, and adds a CRC-32 as an integrity check for the data. The header format also permits the storage of more information than the compress format ...
