Traditional image compression techniques are fine for simple photographs, but they drastically degrade sharp color transitions between adjacent highly contrasted areas - which is why they render type fonts so poorly. One of the main technologies behind DjVu is the ability to separate an image into a background layer (i.e., paper texture and pictures) and foreground layer (text and line drawings). Its main characteristics is that the compress ratio is about 10x better than in PDF format at the same quality. DjVu viewers are available for web browsers, the desktop, and PDA devices. DjVu allows for the distribution on the Internet and on DVD of very high resolution images of scanned documents, digital documents, and photographs. DjVu software enables businesses, publishers and creative professionals to easily exchange and efficiently archive complex color documents without compromising image quality or text legibility.ĭjVu (pronounced "déjà vu") is a digital image format with advanced compression technology and high performance value.
