I am currently learning rails, day to day, and I get more attached. I would like to use Rails to build a Web app with similar functionality like Scribd or Docstoc.

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.

Thanks Matthieu. Ended up just converting PDF's to images. And unzipping the Epubs. pdf.js looks promising as well github.com/mozilla/pdf.js –  Skillachie May 12 '12 at 23:15

Most document conversion systems would most likely be Unix libraries/software; you'll most likely want to establish a list of all the file-types that you want to handle and the way you want to handle them (just convert them to a JPEG, convert to a PDF to preserve the text, etc.). You will also need to offload the document processing to a queue of workers so that your web server does not get bogged down. A good overview of this sort of system was written by Jeremy McAnally about his tldr.it web page summarizing system.
