When I was using tesseract a few years ago (as mentioned earlier
in this thread) I was getting PDFs made of scanned legal documents
(from Groklaw, documents from the SCO v IBM case). These were pretty
awful quality, as if they had been scanned at some terribly low
resolution from what may have been poor quality originals (or copies
thereof). They were very messy to look at, but tesseract could read
most of it fairly well. but converting to higher-resolution TIFF
files actually made the OCR work more poorly, odd as that may seem.
