I´m working on an online bookstore that sells DRM free ebooks in epub format. Are there any libraries in php or js that´ll help me in the process of building a preview component (maybe the first 10 pages) that you know of?
so far I have found this:
Epubjs: http://blog.threepress.org/2009/02/09/introducing-epubjs/
Any help is appreciated.
epubs are just zipped HTML files, so extracting the first HTML file is pretty easy.
Except of course, you sell DRM'd files. If you finished implementing all the decryption stuff, tell us.
