If you know the font type and size, you could do a pixel match against it, but if you don't (which is more likely the case) then it sounds more like OCR to me (Optical Character Recognition).
I don't know of any free source for such a thing,
1 way would be to use a "neural netowrk" and "train" it to learn the letters
sorry I couldn't be of more help

i made a routine to compare a bitmap to another, and it gives me the percent of match.
but this process is not faster and takes alot of memory and time.

I think knowing more about ocr technoly will be better
i dont exactly want a source code, but if there is one for delphi i would be happy.
i don't to know how ocr work, is it a driver, is it based on hooks apis.

some help?
