Transform PDF file into Searchable PDF

Hello,

I wonder if I can I use LiveCycle PDF generator to:

- Get a digitised image file (JPG, GIF, PNG, etc) and return a searchable pdf file

- Get a PDF file which is not searchable and convert it to a new searchable pdf file

Note: I don't want to use a scanner for that, I want to start with the file(image or pdf containing text inside)

         I am asking about it because I was surprised when I saw Adobe Acrobat X text recognition in a not searchable PDF file.

Thanks in advance
