JPEG 2000, first attempt

// July 11th, 2005 // Technology Bits

JPEG2000 LogoI recently learned a bit about a “new” technology called JPEG 2000 (.JP2 or .J2C). I’m a little unsure how this missed me for so long, but oh well.
In a nutshell, JPEG 2000 is a way to store multi-resolution images which can be delivered in a streaming fashion at the desired resolution. It also sports greater compression rates than JPEG, with far less quality loss. It does this using what is called “wavelet technology.” Strange buzzword, I kinda hope it doesn’t catch on…

Anyway, from a practical standpoint, I poked my head into Adobe PhotoShop CS and JPEG 2000 is not listed as a file type I can save as. However, poking around a bit, I found a product by LuraTech called LuraWave which provides a PhotoShop plugin, but alas it only runs in OS9, which I don’t have. I then found Lead Technologies offering a free plugin, but it is PC only… I then decided to step away from PhotoShop and try out Graphic Converter. It’s supposed to convert everything, right? Well, it does, all built-in and functional in the demo.

So now I have one created. The next step is figuring out how to get it embedded in a web page. Luckily a google search turned up this how-to guide. Which implies that all you need to do is use an embed tag. This proves to be an oversimplification, and most likely only compatible with IE.

This is an immature technology, which currently only appears to have support in the PC/IE area. I’m going to try some more tests with this at work on my PC and I’ll post again if I have luck in that area. As a side note, JPEG has been around for 15 years, so I guess it is time for something new here…

    So did you get it to work at all on a website? If so, where is it? I want living proof!

    [...] ENCompass does have data, but no clear way to exchange it cleanly, not that I can imagine a need for this. The web interface again is XSLT customizable. The “archivers” interface is client side, which seems to work out quite nicely. I thought I’d be opposed to this, but recently my use of utilities like ecto and the Gallery plugins has me thinking differently. It does not yet support JPEG 2000, which is really important for archiving things like maps or murals which need to exist in extremely high resolutions to be able to see any of the useful details. It is also passing of the responsibility of all role and user identification to a directory or your ILS. This is a great step in the realm of identity management. [...]

    You can get a free IE plug-in at http://www.morgan-multimedia.com/JPEG2000/. Also Irfanview is a good viewer and Photo-Lux 3.3 is a basic, and free, editor which handles JP2 files. The tech is wonderful and can give excellent size reduction while maintaining quality. Additionaly, unlike jpeg, you do not loose quality every time you edit and save an image.

    I just took another run at it on that Morgan Multimedia site and had a lot more success. Thanks Joe, look for an all new post in the next couple days.

    FYI: JPEG 2000 is supported in Apple Computer’s QuickTime (Mac OS x versions only). This file format is now being used by the Library of Congress for large-scale items like maps (replacing MrSID for that task:

    The format is being investigated by libraries, archives. and museums:
