Question : How to read PDF files and display individual pages in Ruby on Rails?

I'm new to Ruby on Rails. A client has expressed an interest in a project where the server-based app receives PDF files by email, then displays individual pages from the PDF on web pages. What tools could be used to handle the parsing and displaying tasks?

Depending on what you need to do, that might work just fine.
It will convert the page to an image though, which will prevent someone from searching it for text.  Maybe that is fine for what you need though.
