Could't get you exactly. Can you explain a bit more what you want to do ?
It sounds like you want to use Optical Character Recognition (OCR) technology.
You can either launch an external OCR program like BlackDal suggested, or can integrate a 3rd-party OCR library (like "Tesseract":https://code.google.com/p/tesseract-ocr/) into your code.
