What resolution was the output file in? Take a look at the image (e.g. using display) and see if it looks pixelated. OCR needs it to be pretty clear. Oh, there are also a lot of other packages. one list is at: http://www.linux-ocr.ekitap.gen.tr/ > I know nothing about how ocr software works and thought I'd ask > whether anyone has had luck with this package.

It is possible (esp. if the document was scanned), but that's what OCR is for. If it's not a scanned file pdftotext should be able to deal with it (much better than doing OCR). Kuzman Attachment:
