DjVu can be seen as superior alternative to PDF and +Postscript for digital documents, to TIFF (and PDF) for scanned documents, to +JPEG for photographs and pictures, and to GIF for large palettized +images. DjVu is the only Web format that is practical for distributing +high-resolution scanned documents in color. No other format comes close. + +Typical DjVu file sizes are as follows: + +- Bitonal scanned documents: + 5 to 30KB per page at 300dpi, + 3 to 10 times smaller than PDF or TIFF. + +- Color scanned documents: + 30 to 100KB per page at 300dpi, + 5 to 10 times smaller than JPEG. + +- Photos: + 2 times smaller than JPEG, + about the same as JPEG-2000. + +- Palettized images: + 2 times smaller than GIF, + up to 10 times if there is text. + +DjVu is used by hundreds of commercial, governmental, and non-commercial web +sites around the world to distribute scanned documents, digital documents, and +high-resolution photos. + +Demos, and general information about DjVu can be found at +http://www.djvuzone.org, or at http://www.lizardtech.com. + +DjVu was originally developed at AT&T Labs-Research. AT&T sold DjVu to +LizardTech Inc. in March 2000. + + + +2- WHAT IS DJVULIBRE? +===================== + +In an effort to promote DjVu as a Web standard, LizardTech's management was +enlightened enough to release the reference implementation of DjVu under the +GNU GPL in October 2000. DjVuLibre (pronounced like the French "d�j� vu +libre"), is an enhanced version of that code maintained by the original +inventors of DjVu. It is compatible with LizardTech's DjVu software v3.5. + +DjVuLibre includes: + +- A standalone DjVu viewer for Unix under X11 (based on the Qt library). + +- A browser plugin that works with most Unix browsers, including: + Netscape-4.x, Netscape-6.x, Mozilla, Galeon, Konqueror, and Opera. + +- A full-fledged wavelet-based compressor for pictures. + +- A simple compressor for bitonal (black and white) scanned pages. + +- A compressor for palettized images (a la GIF). + +- A full set of utilities to manipulate and assemble DjVu images and documents. + +- A set of decoders to convert DjVu to a number of other formats. + +- An up-to-date version of the C++ DjVu Reference Library + +Windows and Mac versions of the viewer/plug-in, as well as commercial versions +of the compressors and OCR engines are available from LizardTech Inc.. The +compressors provided here are slower, produce larger files, and sometimes +lower quality images than the commercial compressors, but they do the job. + +A variety of free web-based conversion services are also available, including +any2djvu.djvuzone.org, bib2web.djvuzone.org, and openlib.djvuzone.org. + + + + |
