LZMAFile(filename=None, mode='r', *, format=None, check=- 1, preset=None, filters=None) 以二进制模式打开一个 LZMA 压缩文件。 LZMAFile 可以包装在一个已打开的 file object 中,或者是在给定名称的文件上直接操作。 filename 参数指定所包装的文件对象,或是要打开的文件名称(类型为 str, bytes 或...
The lzma file format layout: Offset Size Description 0 1 LZMA model properties (lc, lp, pb) in encoded form 1 4 Dictionary size (32-bit unsigned integer, little-endian) 5 8 Uncompressed size (64-bit unsigned integer, little-endian) 13 Compressed data (LZMA stream) LZMA properties: name ...
lzma .open()方法会创建一个LZMAFile文件实例,第1个参数filename为gz文件的名称。参数mode为打开文件的模式,支持’r’, ‘rb’, ‘a’, ‘ab’, ‘w’, ‘wb’, ‘x’ or ‘xb’ (二进制方式)或者 ‘rt’, ‘at’, ‘wt’, or ‘xt’(文本模式),缺省为 ‘rb’,一般使用‘rb’读取,‘wb’创...
LZMA is a data compressor that works using Lempel-Ziv-Markov chain compression algorithm. It is a fast compressor that gives a faster decompression also. LZMA uses a similar compression algorithm like LZ77. One of the significance of this file format is - it does not mix unrelated bits togethe...
下面是lzma模块的类图,展示了LZMAFile和LZMACompressor类之间的关系。 LZMAFile+__init__(self, filename, mode='rb', format=None, check=-1, preset=None, filters=None, filters_props=None, dict_size=None, uncompressed_size=None, header=None, validate=None)+close()+read(size=-1)+write(data)LZ...
node-xz via lzma.Compressor and lzma.Decompressor LZMA-JS via lzma.LZMA().compress and lzma.LZMA().decompress, though without actual support for progress functions and returning Buffer objects instead of integer arrays. (This produces output in the .lzma file format, not the .xz format!)...

Language:All Sort:Most stars ionescu007/minlzma Star354 The Minimal LZMA (minlzma) project aims to provide a minimalistic, cross-platform, highly commented, standards-compliant C library (minlzlib) for decompressing LZMA2-encapsulated compressed data in LZMA format within an XZ container, as can...
LZMA file format The LZMA header is not well documented. It's also a bit usual: it doesn't appear to have a magic byte prefix, as one would expect from a modern file format, and it not word-aligned. Nevertheless: Offset Size Description 0 1 lc, lp and pb in encoded form 1 4 dic...
