压缩，但并不是Zip文件！
　　Xceed Streaming Compression Library是一个高性能的“raw”压缩库。它提供压缩和解压流数据，缓存，字符串，或单一文件的功能，并支持多种压缩数据格式。不像 Xceed Zip Compression Library, 这种更为集中的库并不提供 Zip 文件处理功能。

多种压缩类型
　　该库提供两种非常著名的压缩算法来满足你的应用程序的需求。为了快速压缩和解压，你可以使用库的 Deflate 算法。还有一种同样采用行业标准的 zip 文件格式，它可以实现更好的压缩。

还可以处理文件格式
　　该库可以在 Unix 和 Linux 平台压缩/解压 GZip (.gz) 和 BZip2 (.bz2) 文件，以及处理 Zlib, Info-Zip 和兼容的 Java 数据，也支持 Xceed Zip v3.x 和 v4.x 内存压缩数据 (非 Zip)。

Xceed 品质贯彻始终
　　如同所有的 Xceed 组件，该库设计为保持灵活性，并且非常容易使用。实际上，它只需一行代码来压缩和解压内存或文件。

• 在所有的 32 位开发环境下工作，可以使用 ActiveX 控件，包括 VB, VC++, Delphi, C++ Builder, VFP, Office, PB, VO, Web 脚本语言， ASP 和 DCOM 项目。

• 压缩和解压引擎。

• 快速，低内存使用的压缩引擎。

• 提供 "Deflate" 的压缩方法，以更好，快速的压缩，并且提供 "BZip2" 算法以获得最大压缩。

• 为每个压缩算法控制压缩级别。

• BZip2 压缩算法能够很好的压缩 XML 数据。

• 可以在 Unix 和 Linux平台压缩和解压 GZip (.gz) 和 BZip2 (.bz2) 文件。

• 可以压缩和解压 Zlib, Info-Zip 以及 Java兼容数据。

• 可以压缩和解压 Xceed Zip v3.x 和 Xceed Zip v4.x. 创建的内存缓存。

• 可以内嵌 CRC 或 Adler-32 校验和，来输出压缩数据，以确保数据的完整性。

主要操作

• 直接从一个内存缓存压缩和解压缩到另一个内存缓存。

• 从文件压缩和解压缩到内存，或从内存压缩和解压缩到文件。

• 从一个文件压缩和解压缩到另一个文件。

• 所有的压缩和解压缩模式都支持流数据。

• 在原始数据中计算 CRC 或 Adler-32 校验和。

• 可以有效自动地与 Xceed Encryption Library 和 the Xceed Binary Encoding Library 一起工作，在压缩或解压文件前，来加密/解密，编码/解码数据。

文件和示例

• 提供 MSDN 类型 的 HTML 格式的完善的，全面的文档，它是完全的上下文相关，在IDE上按下F1键时，会打开相关主题的手册。

• 为各种语言充分注释示例应用程序，包括VB, Delphi, 使用 ATL 和 MFC 的 Visual C++, C++ Builder 和 Active Server Pages.

Compression, but not Zip files!
　　The Xceed Streaming Compression Library is a high-performance "raw" compression library. It offers the ability to compress and decompress streaming data, buffers, strings or single files and supports multiple compressed data formats. Unlike the Xceed Zip Compression Library, this more focused library doesn't offer Zip file handling capabilities.

Multiple compression types
　　The library offers two well known compression algorithms to suit your application's needs. For fast compression and decompression speeds, you can use the library's Deflate algorithm. It's the same one used in the industry standard zip file format and it achieves pretty good compression.

It can do file formats, too
　　The library can compress and decompress GZip (.gz) and BZip2 (.bz2) files from Unix and Linux platforms, as well as handle Zlib, Info-Zip and Java-compatible data. Xceed Zip v3.x and v4.x memory-compressed (not Zip) data is also supported.

Xceed quality throughout
　　Like all Xceed components, this library is designed to be flexible yet extremely easy to use. In fact, it only takes one line of code to compress and decompress memory or files.

ActiveX Technology

• A single fully self-contained COM object and ActiveX control written with ATL 3.0.
• Requires no external compression DLLs, MFC DLLs or runtime libraries.
• Both single-threaded (STA) and multi-threaded apartment (MTA) model design.
• Instantiate the component dynamically without putting it on a form.
• Supports multiple instances running simultaneously.
• When running on Windows NT, 2000 or XP, the library automatically switches to native Unicode API calls for best performance.
• ActiveX control interface has all constants, enumerations and types built-in. Code completion, property categories, help strings and context-sensitive F1-help fully supported.
• Works with all 32-bit development environments that can use ActiveX controls, including VB, VC++, Delphi, C++ Builder, VFP, Office, Web scripting languages, ASP and DCOM projects.
• Compression and decompression engine
• Fast, low memory usage compression engine.
• Offers the "Deflate" compression method for good, speedy compression and the quot;BZip2" method for maximum achieved compression.
• Control the compression level for each compression method.
• BZip2 compression method is excellent for compressing XML data
• Can compress and decompress GZip (.gz) and BZip2 (.bz2) files from Unix and Linux platforms.
• Can compress and decompress Zlib, Info-Zip and Java-compatible data.
• Can compress and decompress memory buffers produced by Xceed Zip v3.x and Xceed Zip v4.x.
• Can output compressed data with embedded CRC or Adler-32 checksums to ensure data integrity.

Major operations

• Compress and uncompress directly from one memory buffer to another.
• Compress and uncompress from file to memory or from memory to file.
• Compress and uncompress from one file to another.
• All compression and decompression modes support streaming data.
• Calculate CRC or Adler-32 checksums on raw data.
• Can efficiently and automatically work together with the Xceed Encryption Library and the Xceed Binary Encoding Library to encrypt/decrypt/ encode/decode data before compressing or decompressing it.

Documentation and samples

• Complete, comprehensive documentation provided in an MSDN style HTML format which is fully context-sensitive so that pressing F1 on a keyword in your IDE opens up the manual to the correct relevant topic.
• Fully commented sample applications for various languages, including VB, Delphi, Visual C++ with ATL and MFC, C++ Builder and Active Server Pages.
