Xceed Real-Time Zip for Windows Phone released

Tue, 06 Sep 2011 10:42:00 GMT

Zipping files using Xceed Real-Time Zip for Windows Phone.

Add zip/unzip to any Windows Phone application.

Xceed Real-Time Zip for Windows Phone uses no intermediate memory storage. Helps make mobile apps easier on data plans. Xceed Real-Time Zip for Windows Phone lets developers add zip and unzip to any Windows Phone mobile app quickly and easily. Xceed Real-Time Zip for Windows Phone uses no intermediate memory storage or temporary files, helping to overcome the limited hardware of typical smartphones (compared to a PC). It also helps make your apps easier on data plans.

Features

The product's main ZipWriter and ZipReader classes use any seekable or non-seekable Stream-based object as the target or source Zip archive, respectively, for complete flexibility and "on-the-fly" compression/decompression.
Lightweight libraries.
Creation of Zip archives begins as soon as data to compress has been received: no waiting for all of the files, or even for complete files. It does not need to know in advance the number or size of files.
Zip archives can be immediately sent over a network as soon as the creation process has begun, and the remainder of the archive becomes available as it is compressed.
Secure: Because no temporary files are used while creating a Zip file, there is less chance of unauthorized access or modification of files during the Zip creation process.
Archived files are extracted and available instantly for further processing by the application even if the component is still receiving the Zip archive.
The size or number of files in a Zip archive has absolutely no impact on memory and disk-space requirements.
Just a few methods and properties are needed to perform powerful Zip compression/extraction.
Supports the BZip2, BWT, Deflate, Deflate64™, and PPMd compression methods.
Provides four compression levels.
AES encryption and decryption are supported for maximum security and WinZip compatibility.
The only library to provide WinZip 12 compatibility, supporting the LZMA algorithm for improved compression in certain situations. Note: Zip files using WinZip 12's special JPEG recompression feature are not supported.
UTF-8 character encoding is available in headers for improved support of international characters in filenames and comments.
Events and properties to monitor and control the zip/unzip operations are also provided.
Reads the Xceed Unicode Extra Header, so it can now preserve filenames with Unicode characters. Very useful for handling international characters.
Compatible with older zip tools.
The ZipWriter can generate uncompressed zip files that the product's ZipReader can read increasing flexibility (combines the Deflate format and no compression).
Includes license and key for Xceed Real-Time Zip for Silverlight.

Noemax joins ComponentSource

Fri, 17 Jun 2011 17:28:51 GMT

GZip performance sample included with DotNetCompression.

DotNetCompression provides better compression for .NET and WCF-Xtensions allows you to accelerate your Web services.

DotNetCompression provides implementations of the GZIP and DEFLATE Internet Standards that offer better compression and more features than the corresponding System.IO.Compression classes of .NET. DotNetCompression offers you higher compression ratios and enables you to specify the compression level so that you can select the desired balance between performance and compactness. It lets you add a filename so that the original filename can be restored during decompression, and also let you access other metadata in the header.

Features

Higher compression ratios - Noemax have compressed 392 documents using the GZipStream class of DotNetCompression and the GZipStream class of .NET. The results demonstrated that DotNetCompression can deliver consistently and significantly better compression.
Selectable compression level - DotNetCompression enables you to select between nine levels of compression, where level 9 provides the best compression while level 1 consumes the least processing resources. There is also level 0 which uses the GZIP format but does not compress the stream.
Original filename and other header metadata - Adding a filename to the header metadata enables you to restore the original filename when decompressing. Other metadata can also be written to or read from the GZIP header.
GZIP and DEFLATE Internet Standards - DotNetCompression implements two Internet Standards, the DEFLATE Compressed Data Format Specification (RFC 1951) and the GZIP File Format Specification (RFC 1952), providing interoperability with implementations on other platforms that are compliant to these standards.
Runs on both .NET and .NET CF - The higher compression ratio offered by DotNetCompression is particularly important for .NET Compact Framework applications running in low bandwidth environments as every additional reduction in size is significant in improving communication speed and reducing storage requirements.
Easy to switch - Switching to DotNetCompression brings immediate benefits with minimum effort. Your existing code can be easily converted to use the classes of DotNetCompression instead of the System.IO.Compression classes of .NET as the names of the classes are the same and they share the similar interfaces. DotNetCompression includes an MSDN-style class reference that integrates into the Visual Studio Combined Help Collection and offers IntelliSense context sensitive help within your project.

WCF-Xtensions will help you deliver the best performance for your WCF services and clients whether you are developing for .NET, CF, Silverlight or Azure. WCF-Xtensions consists of bindings, binding elements, behaviors, factories and clients that reduce message size and bandwidth consumption to a minimum and can greatly improve the response times of your applications. WCF-Xtensions components are straightforward to add to your code or configuration file and work unobtrusively without requiring any other changes.

Features

HTTP content negotiation & compression - Enables you to improve efficiency by transparently introducing support for new message encodings and compression algorithms on the same HTTP endpoint while retaining interoperability with existing clients. Lets you choose between several content negotiation modes.
Fast Infoset message encoding - A compact, standards-based, cross-platform binary XML message encoding for WCF. Full interoperability with Java. Many new features and improvements in v4.
Message compression - Can be used with any transport. Compresses both request messages and response messages. Enables you to select the compression algorithm and the compression level.
Transport compression - Fast, stateful, transport-level compression. Impressive reduction in message size at the lowest processing expense. Works with transports that support stream upgrade.
Compact envelope - Improves compactness and performance without changing the binding's configuration. Can be used with message security to accelerate encryption and reduce the size of encrypted messages.
SOAP/TCP transport - Provides duplex communication between .NET, CF and Silverlight, very good streaming performance and support for stateful Fast Infoset. Can be used to host services on CF and is interoperable with the Java implementations available in GlassFish and Tomcat.
LiteHTTP transport - A high performance, lightweight HTTP implementation with embedded HTTP content negotiation and compression. Does not need a configuration utility and can be used to host services on CF.
Compression algorithms - A choice of different compression algorithms for different needs. The GZIP and DEFLATE of WCF-Xtensions offer better compression than System.IO.Compression, LZF3 and LZF offer unprecedented speed, and LZMA offers the highest compression ratios.

About Noemax

Noemax is a component vendor that provides a broad set of communication, binary XML and compression technologies for increasing the efficiency of transporting, processing and storing data. Developers use Noemax products to transparently enhance the performance and expand the capabilities of their .NET, Compact Framework, Silverlight, Azure, Windows Phone 7 and Xbox 360 software and to widen interoperability with Java and other platforms.
