  DjVu - Wikipedia, the free encyclopedia

DjVu format will be used by the One Laptop per Child project in order to easily supply existing paper books in an eBook format.
DjVu is always a raster format, while PDF supports vector format depending upon the input data.

 DjVuLibre: Open Source DjVu library and viewer
DjVu is a web-centric format and software platform for distributing documents and images.
DjVu is used by hundreds of academic, commercial, governmental, and non-commercial web sites around the world to distribute scanned documents, digital documents, and high-resolution photos.
DjVu can be seen as nicely complementing PNG and MNG (which, unlike DjVu are lossless formats) in the areas of document image compression and lossy photo compression.

 DjVu at ICAO
DjVu typically achieves compression ratios about 5 to 10 times better than existing methods such as JPEG and GIF for color documents, and 3 to 8 times than TIFF for fl and white documents.
DjVu files are also about 3 to 8 times smaller than fl and white PDF files produced from scanned documents (scanned documents in color are impractical in PDF).
DjVu, on the other hand, never decompresses the entire image, but instead keeps the image in memory in a compact form, and decompresses the piece displayed on the screen in real time as the user views the image.

 DJVU - OLPCWiki
DJVU is intended to be used with scanned images of book pages, either fl and white or full color.
DJVU is supported by the Evince reader which is being used by the OLPC project.
DJVU readers are capable of using the OCR to do text searches and then highlighting the words in the actual scanned text image.

 LizardTech DjVu Business FAQ
DjVu is also the ideal format for the growing e-book marketplace.
DjVu achieves its stunning results through separating a scanned document into a layer containing hard edges (like text) and another layer containing colors and softer edges (like photographs).
DjVu removes the barriers to storing color scans by creating color documents that are significantly smaller than PDF files.

DjVu gives you the ability to zoom in on documents in real time or to pan around images larger than your screen (see Figure 1).
DjVu plugins are available for standard Web browsers on Linux and most versions of Unix, Windows, and Mac OS.
Maybe DjVu's greatest value is not that it makes scanned documents quickly viewable from the Internet, but rather that it makes us realize that almost nothing of our paper memory is already on the Internet in the first place, regardless of the format.

 Yann's DjVu Page
DjVu (pronounced déjà vu) is an image compression technique, a file format, and a software platform, designed bring paper documents and high resolution photos to the Internet.
With DjVu, a fl and white page scanned at 300 DPI occupies 5 to 30 KB, which is 3 to 8 times less than with the currently popular TIFF Group-IV format.
DjVu was developed at AT&T Labs in Red Bank NJ by a research team composed of Yann LeCun, Leon Bottou, Patrick Haffner, Paul Howard, Pascal Vincent, Yoshua Bengio, and Bill Riemers.

 pdaBuzz > pdaBuzz Home > Review - DjVu for PalmOS
DjVu, pronounced "déjà vu", is a new image compression technology.  It has an option to include OCR as well.  Its claim is that DjVu promises smaller file sizes than even jpeg.  The sites example goes as follows: Tif 31.2MB, Jpeg 604KB, and DjVu 70KB.  With numbers like that, I had to read on.
This is the (only) djvu file that worked for me in GrxView Pro.  The pages are listed as though they are individual files, but the 1133K on the right is the size of the whole book, which has 157 pages.
I hope work continues on djvu for Palm to handle the Fatal Alerts, and that a Palm is made with a 640x480 pixel screen.

Other demonstrations that DjVu is ideal for mathematical publications: Vladimir Lotov's page at the Sobolev Institute, Ken Brown's page at Cornell University, and Alberto Candel's page at California State University, Northridge.
While the DjVu plug-in is freely available and easy to install, some users may prefer to view DjVu content without having to install a plug-in.
If you are asking yourself why DjVu hasn't had more users and exposure in the past, it's because the previous LizardTech managers never understood that their "niche market" approach was doomed.

DjVu decomposes each page into multiple components (text, backgrounds, images, libraries of common shapes...) that may be shared by several pages and downloaded on demand.
DjVu is an image compression technique, a document format, and a software platform for delivering documents images over the Internet that fulfills the above requirements.
The DjVu technology was initially created by a few researchers in ATandT Labs between 1995 and 1999.

DjVu is ideal for scan-to-Web applications where corporations benefit from digitizing billions of pages of documents, manuals and other paper-based information for easy sharing over the Internet or corporate Intra nets.
DjVu allows companies to scan, store and download documents 20 times faster than JPEG or GIF and at compression ratios as high as 500:1.
DjVu achieves its stunning results through separating a document into a bitmap (fl and white) portion and a color photo-imagery portion and encoding them with different techniques to enable smaller storage requirements and instant downloads.

 [No title]   (Site not responding. Last check: 2007-10-22)
As such, the DjVu media format does not in itself create additional security risks, since the fields are not used to induce any particular behavior by the recipient application.
The DjVu media format has an extensible structure, so that it is theoretically possible that fields could be defined in the future which could be used to induce particular actions on the part of the recipient, thus presenting additional security risks, but this type of capability is not supported in the referenced DjVu specification.
DjVu viewer implementations should detect and report this condition by comparing the DjVu version number embedded in every DjVu media file with the highest supported DjVu version number.

 What is DjVu?
DjVu is a an image format that can efficiently display images and textual materials that have been scanned into digital form.
It is viewable through a browser plug-in in the same fashion as PDF files are with the Adobe Acrobat browser plug-in, see the next section for further information on getting the plug-in for your computer.
If you are having trouble with viewing the DjVu documents of the New Jersey Digital Legal Library or if you are having trouble installing the plug-in on your personal computer send email detailing the problem to njlegallib.

 DjVu - SWiK
DjVu or (deja-vu) is an open image file format for ‘printed’ documents, akin to PDF.
DjVu supports various image features such as layering, progressive download, and lossy compression, features which are useful for internet distribution of documents.
DjVu was originally created by [[Yann LeCun]] at ATandT in 1996, and a GPL implementation [[DjVuLibre]] has been maintained since 2000, when [[LizardTech]] bought the rights to DjVu from ATandT.

 New DjVu Version 25 Has Compatability Issues   (Site not responding. Last check: 2007-10-22)
Note that when the DjVu file is a single-page document, the "Save Document As" option is disabled and only the "Save Page As" option is available.
When the DjVu file is a multi-page document, both the "Save Document As" and "Save Page As" options are available.
The first compatability problem with Version 25 DjVu files is that it is only the Windows plugin, and no other DjVu applications, that are currently writing Version 25 files.
