I also remember at least one OCR tutorial recommending some preprocessing to make images easier for the OCR program to work with, and I believe they used the convert command provided by imagemagick to do so, but I forget the details. Also, it's been a while since I've attempted any OCR'ing myself(how often I had to manually clean up the output kind of put me off), so there might be others on this list who can provide better, and more specific advice on this subject. Still, I hope I've at least got you started on the right track. -- Sincerely, Jeffery Wright Bachelor of Computer Science President Emeritus, Nu Nu Chapter, Phi Theta Kappa.
