How to do OCR on a PDF document?
I've got a >200 page pdf manual that was produced by scanning hard copy. I'd like to convert it to a searchable text format, but am not having any success finding a tool to do so. Google's search results are highly polluted with crippleware trial software that can only do the first few pages of the file. The only truly free application I found, FreeOCR's pdf renderer fails to handle anything beyond the first few pages of the file.
Google's pdf viewer does OCR; but doesn't appear to provide any export option other than copy/paste; in addition to being very tedious, what it puts on the clipboard is only plaintext; which means I'd lose all of the line art and significant formatting due to horizontal placement.
