Hi, A few points. 1. for OCR under linux, use tesseract and ocropus. The results is a lot better than with gocr or ocrad. 2. for converting images, use the convert command provided by the ImageMagic package. Ocropus/tesseract is a little slow, but worth the effort to get going. With convert, you can do a lot of other nice things on images like change them from collor to blak and white or change the contrast and so on.
