Notes on the LZMA format This package endeavors to maintain file-format compatibility with thelzmacommand-line utility on Linux (which itself tries to provide command-line compatibility with thegzip). This utility is found in the 7-Zip SDK distribution inCPP/7zip/Bundles/LzmaCon/lzmp.cpp. ...
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...
format:指定压缩格式,可选择lzma.FORMAT_XZ或lzma.FORMAT_ALONE。默认值为lzma.FORMAT_XZ。 preset:指定压缩级别,取值范围为0到9,其中0表示无压缩,9表示最高压缩率。默认值为6。 check:指定校验类型,可选择lzma.CHECK_NONE、lzma.CHECK_CRC32、lzma.CHECK_CRC64等。默认值为lzma.CHECK_CRC32。 下面是一个示例,演...
lzma.compress(data, format=lzma.FORMAT_XZ, check=lzma.CHECK_CRC64): 压缩数据。 lzma.decompress(data, format=lzma.FORMAT_XZ, memlimit=None, flags=None): 解压缩数据。 你可以根据你的需求来调用这些函数和方法,并传入相应的参数。 总结 通过本教程,我希望你能够了解如何在Python中安装和使用lzma模块。首...
在http://www.7-zip.org/sdk.html网页上提供了LZMA的SDK开发包下载,包中的一级目录中包含了如下内容:ASM, C, Cpp, CS, Java文件夹,和7zc.txt、7zformat.txt、7zr.exe、history.txt、lzma.exe、lzma.txt、methods.txt文件。lzma.txt是重要的SDK文档,其中介绍了LZMA的目录结构和一些方法的使用,这个文档应该...
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 be generated with Python 3.6, 7-zip, and xzutils. Ad...
MariaDB 10.7 是 MariaDB 10.6 的更新版本,带来几个全新功能。 MariaDB 是由 MySQL 的原作者制作的流行数据库服务器。它是社区开发的 MySQL 分支,是使用最广泛的开源关系数据库管理系统 (RDBMS) 之一。MariaDB 与MySQL高度兼容,允许用户轻松地将数据库从 MySQL 迁移到 MariaDB。

Abstract The XMill is an efficient XML compression tool which takes the advantage of awareness of XML. XMill compresses the data on the basis of three principles- separate the XML structure from the data, group related data and apply the semantic compressors. The XMill uses the gZip library to...
Note: At least nowadays, AS3'sByteArray.decompress()supports LZMA decompression, so I'm using that, but it doesn't directly support the SWF LZMA format, only LZMA, so there's a bit of tinkering to be done, also note that this code can probably be improved a bit. ...
