JPEG XR

JPEG XR (abbr. for JPEG extended range) is a still-image compression standard and file format for continuous tone photographic images, based on technology originally developed and patented by Microsoft under the name HD Photo (formerly Windows Media Photo). It supports both lossy and lossless compression, and is the preferred image format for Ecma-388 Open XML Paper Specification documents.

Support for the format is available in Adobe Flash Player 11.0, Adobe AIR 3.0, Sumatra PDF 2.1, Windows Imaging Component, .NET Framework 3.0, Windows Vista, Windows 7, Windows 8, Internet Explorer 9, Internet Explorer 10, Internet Explorer 11. As of August 2014, there were still no cameras that shoot photos in the JPEG XR (.JXR) format.

History

Microsoft first announced Windows Media Photo at WinHEC 2006, and then renamed it to HD Photo in November of that year. In July 2007, the Joint Photographic Experts Group and Microsoft announced HD Photo to be under consideration to become a JPEG standard known as JPEG XR. On 16 March 2009, JPEG XR was given final approval as ITU-T Recommendation T.832 and starting in April 2009, it became available from the ITU-T in "pre-published" form. On 19 June 2009, it passed an ISO/IEC Final Draft International Standard (FDIS) ballot, resulting in final approval as International Standard ISO/IEC 29199-2. The ITU-T updated its publication with a corrigendum approved in December 2009, and ISO/IEC issued a new edition with similar corrections on 30 September 2010.

WDP (company)

WDP, LTD, and more recently doing business as Angel Paintball Sports, is a former manufacturer and distributor of paintball markers and equipment located in England. The company also owns and operates National Paintball Fields, a paintball playing site in Birmingham. WDP is best known for manufacturing the Angel line of electropneumatic paintball markers.

Now in administration.

History

WDP began operating in 1987 with the opening of the National Paintball Fields playing site. Once the field became successful, the company opened a shop and soon began running paintball tournaments in order to stimulate local demand for paintball equipment. Not content with woodland tournament play, WDP pioneered the "arena" paintball concept, introducing what would be called "Hyperball" - a speedball arena field constructed from corrugated plastic pipe and designed for a much faster game format.

The first product introduced by the company was the Mamba Remote Coil hose - a coiled high pressure air line for connecting high pressure air and CO₂ gas systems to paintball markers remotely.
