General Documentation
DjVu: a Tutorial

A tutorial for end-users, web designers, and developers, on creating, viewing, and publishing DjVu documents, including:
  • when/why use DjVu rather than other formats.
  • how to scan or create material for conversion to DjVu.
  • which DjVu compression tool should be used, and how to use them to produce DjVu images and documents.
  • how to publish DjVu documents on a web site and optimize the user experience.
  • how to trigger the plug-in autoinstall feature.
  • how to index DjVu documents and provide full-text search capabilities.
  • how to add hyperlinks, highlights, and metadata to DjVu documents.
  • how to configure a web server to serve DjVu pages, so that Netscape users won't see gibberish instead of a DjVu image in their browser window.
