DjVu (pronounce "Deja vu") is a compact and versatile document format. It is generally more compact than PDF (to 10 times smaller) and is very efficient to store scanned documents. There are a some large online libraries that provide a number of books in DjVu file format. the main source of information is to be found at djvu.org. Many documents are freely available in DjVu format, for example at www.archive.org. You may download them with Safari and open them with DjVu Reader. If an outline is present it is displayed and can be used to access the outlined parts of the document. the outline is editable so to permit to browse with ease through the document. A slider allows to paginate rapidly and conveniently to any point of the document. DjVu documents are generally made of pictures of actual books or documents that are processed in DjVu format. So DjVu documents are image based, where each image represent a full page. So pages are like the genuine one and shown as a full image. Browsing through a DjVu documents is then a page by page image browsing. DjVu Reader permit a browsing of most DjVu Documents that you may find. (Tapping left or right will turn the pages: soon.) Tapping on the center will toggle full screen viewing. PDF documents are supported. Outline in PDF documents is usable to browse rapidly through the document when available. Not all PDF documents have an outline though. Position in opened documents is remembered the next time you open it. You can contribute to the future of the app by suggesting improvements. I will do my best to include the one I can manage. I use DjVu Reader regularly and have made this app to be able to read the documents I have. So I will try to make this app as versatile as possible. the Help contains more use explanations and some future improvements that were asked or that I want to implement. Other fil types will be added in next releases.
