Does Digital Editions support JPEG 2000?
No, the current release of Digital Editions does not support JPEG 2000. Therefore, a few books do not render (for example, color illustrations in Google Books, some comic book editions, and some technical book illustrations). The Digital Editions team is working to support JPEG 2000 and is planning on releasing it with the next version of Digital Editions.
Digital Editions supports bookmarks, highlights, and text notes via its bookmarks panel. These annotations are stored in an open XML format separately from publications to enable seamless annotation across PDF- and EPUB-based publications. They will set the stage for future social networking features (such as sharing annotations within a community of readers).
