Definitions for "DjVu"

An electronic document format primarily useful for scanning documents. Key features are support for different resolutions and compression types for photo areas of an image versus text. Uses a variant of JBIG2 compression from binary image data and wavelets for continuous areas, such as photos. For more information, see http://www.princetonimaging.com/djvu
Pronounced "deja vu". It is a compressed graphics format for showing scanned pages on the web. It does for scanned pages what PDF format does for electronically created documents. It requires a plug-in from AT&T. It uses a combination of compression formats that handles sharp-edged text one way and photographs and color blends another way, thus giving better compression than GIF, JPEG, or PNG can do. The server the document is placed on must be set for the MIME types x-djvu, djvu, and djv. For more information, see the AT&T DjVu FAQ.
