About the DjVu Web Browser Plug-in

With the DjVu™ Web Browser Plug-in 3.2, any Internet user can view highly-detailed color pages of books, magazines, catalogs, manuals, even historical documents, in full, vivid detail that's a pleasure to read and lightening-fast to download. The DjVu Web Browser Plug-in harnesses the power of the DjVu imaging language to allow any personal computer user to view the most advanced image files available.

Introduction to DjVu

DjVu is a highly sophisticated imaging language based on six advanced technological breakthroughs developed at AT&T Labs. Working together, they provide a reliable means of saving detailed scans at remarkably low file sizes.

Conventional image-viewing software decompresses images in their entirety before displaying them. This is impractical for high-resolution document images since the large file sizes involved typically exceed the capacity of most PCs. DjVu, on the other hand, never decompresses the entire image, but instead keeps the image in memory in a compact form and decodes only the piece displayed on the screen in real time as the user views the image. As a result,- the initial view of the page loads very quickly, and the visual quality progressively improves as more bits arrive. DjVu can achieve file size reduction ratios as much as 500:1 while preserving excellent image quality.
