Vista fires warning shot at JPEG images
by Grant Robertson Jan 30th 2007
There are few file formats ubiquitous as JPEG (ASCII text comes to mind). It's almost universally compatible, available in every image handling application you could possibly want to use and, it works swimmingly well. Who could possibly want to change all that? Microsoft, that's who. Last year Microsoft began promoting its Windows Media Photo format, recently renamed HD Photo (ostensibly to gain a little street cred from public familiarity with HDTV), as a "better" alternative to the standard JPEG. According to Microsoft's specification literature, HD Photo gives twice the quality compared to JPEG at similar file sizes. Vista includes built-in support for HD Photo and, Microsoft has been actively promoting HD Photo to camera manufacturers as a superior alternative to the aging JPEG specification.
Sounds great, where's the catch? Licensing. Patents surrounding JPEG have expired, meaning if you want to include JPEG support in your application, and be universally compatible with other applications supporting JPEG, you don't have to pay fees to any company or individual. HD Photo is a published standard, but it's owned by Microsoft lock, stock, and barrel.
Update : HD Photo is licensed under the Open Specification Promise, under which Microsoft vows not to enforce its patent rights as long as developers conform to the specification. Thanks to Bob for straightening me out!
With Halloween fast approaching, it's a great time to get in some practice defending your territory against zombies. In Graveyard Shift, you take aim at zombies and other creepy-crawlies, blasting them into splatters of cartoony green guts. It's a casual first-person shooter, and it's very easy to get the hang of - use the mouse to aim, click to fire. Graveyard Shift has at least 15 levels, and it might even have some secret stages I haven't unlocked yet.
They key to getting good at Graveyard Shift is learning to use ...
