About DjVu®

DjVu is a new file compression technology developed by the renowned AT&T Labs that affords transmission of high quality images over the Internet with very little degradation.  It is my opinion that the compression for my music deployment is 7-10 times better than Adobe's Acrobat.  

To bring you the best viewing experience possible, I have selected DjVu as my preferred image format.  Not only will you see a higher definition image in your browser, you should be able print out the image on your printer at 400 dots per inch and have a high quality rendition.  

AT&T granted an exclusive license to LizardTech, Inc., of Seattle Washington, to exploit their DjVu technology.  The marketing paradigm for Djvu is identical to Adobe's Acrobat: make the readers free to everyone so they can view the files without having to pay for their software.  LizardTech makes its money off of selling the encoders which generates the files you view.  In June of 2003, LizardTech was purchased by a Japanese corporation for approximately $11 million (Adobe missed out on a bargain opportunity here).

The djvu browser plug-in only requires about 400K of disk space, once installed, and does not take long to install.  LizardTech's free plug-in for web browsers (MSIE and Netscape compatible) is located here:   LizardTech supports windows, mac and Unix operating systems.

I highly recommend you download and install the free plug-in.

Here is High quality DjVu music sample.

One notable deployment of DjVu technology is the Century Dictionary Online 12 volumes consisting of 10,000 pages containing 500,000 definitions!  It is the largest freely available dictionary on the world wide web.

See for yourself before installing the Plug-in

To see what DjVu encoded music would look like on your computer terminal, here are some screen shots (72 dpi) taken from from a computer screen that is displaying the Mendelssohn Piano Trio (opus 49 D moll) for piano duet saved in DjVu format.  Each screen shot was taken at a display rate of 100% or more (taking a screen shot of something less than 100%, i.e "full size", does not show you anything meaningful about how effective this compression technology is).
