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.
