| PackageDescription | DjVu is a web-centric format and software platform for distributing documents
and images. DjVu content downloads faster, displays and renders faster, looks
nicer on a screen, and consume less client resources than competing formats.
DjVu was originally developed at AT&T Labs-Research by Leon Bottou, Yann
LeCun, Patrick Haffner, and many others. In March 2000, AT&T sold DjVu to
LizardTech Inc. who now distributes Windows/Mac plug-ins, and commercial
encoders (mostly on Windows)
In an effort to promote DjVu as a Web standard, the LizardTech management was
enlightened enough to release the reference implementation of DjVu under the
GNU GPL in October 2000. DjVuLibre (which means free DjVu), is an enhanced
version of that code maintained by the original inventors of DjVu. It is
compatible with version 3.5 of the LizardTech DjVu software suite.
DjVulibre-3.5 contains:
- 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/PNG).
- A 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. |
