Hi, I am new to rails. I need to edit an existing pdf file and fill in some data and send it to browser, how to implement this? Is there an example online I can look at it?

You might be able to use prawn to do that.

Thanks for response. Can you give me an example for this? Can prawn edit existing pdf file? Craig White wrote:> On Tue, 2010-03-09 at 01:29 +0100, John Wu wrote: >> Hi, >> >> I am new to rails.
