Hi! DjVu format
Over 90 percent of the information in the world is still on paper. Many of those paper documents include color graphics and/or photographs that represent significant invested value. And almost none of that rich content is on the Internet. |
That's because scanning such documents and getting them onto a Web site has been problematic at best. At the high resolution necessary to ensure the readability of the text and to preserve the quality of the images, file sizes become far too bulky for acceptable download speed. Reducing resolution to achieve satisfactory download speed means forfeiting quality and legibility. Conventional web formats such as JPEG, GIF, and PNG produce prohibitively large image files at decent resolution. As a result, Web site content developers have been largely unable to leverage existing printed materials.
DjVu (pronounced "déjà vu") is a new image compression technology developed since 1996 at AT&T Labs to solve precisely that problem. DjVu allows the distribution on the Internet of very high resolution images of scanned documents, digital documents, and photographs. DjVu allows content developers to scan high-resolution color pages of books, magazines, catalogs, manuals, newspapers, historical or ancient documents, and make them available on the Web.
Information that was previously trapped in hard copy form can now be made available to wide audience.
