I have personally used cuneiform for linux mostly. I cannot remmeber if it can natively manage PDF files (possibly, certainly it can do more than TIFF), however you could use a conversion tool (memory seems to say pdf2tiff).

Has anyone figured out how to get one of the Linux OCR engines (like tesseract) to accept a graphical file (other than .tiff) as input? In particular I'm going to be swamped with graphical PDF files this year. Printing these just to scan them seems both wasteful and inefficient. I know people do this on other OS's. Has anyone suggestions on how to do this in Linux? All suggestions greatly appreciated.
