This does not necessarily mean, however, that the actual page content is loaded once for all pages. If the book@thumbpathattribute is set, thumbnails will be "generated" from the pregenerated thumbnails, by loading those images and storing that graphic. When a page's content is loaded for the first time (because the page comes inside the range of loaded pages) this graphic will be replaced with an automatically generated snapshot.http://www.megazine3.de/doc/Book 2013/9/3
