I used tesseract-ocr, mentioned previously, a couple of years ago with
very good success.  Also, the problem he's trying to solve is much
simpler than the general OCR problem; he's got the actual correct pixels
(rather than a scan), and maybe even have knowledge of what fonts are
used.  That makes a huge difference.
