What components/gems/plugins/libraries in Rails or Ruby could be used to create a web app with similar functionallity ?
The web app should be have the
- Epub coversion to image(jpeg) as well as pdf
- PDF conversion to image (jpeg) as well as epub
- PDF to Epub
I would just like suggestions on the libraries or plugins, etc... to use to obtain the above functionalities using Rails, and what makes them special.
