Earlier this month Adobe launched the fifth incarnation of their desktop publishing tool
Adobe InDesign C3, worshiped by publishing companies all over the globe. And one of the most interesting new features (at least for us) is the ability to export of content into the same XHTML-based e-book format that is supported by the
Adobe Digital Editions reader software.
During the export, InDesign creates a single .epub file containing the XHTML-based content. The exported file can also include a JPEG thumbnail image from the first page in the specified document. This thumbnail is used to depict the book in the Digital Editions Reader library view.
