Are there any freeware OCR (optical character recognition) components? I have found only this one - _http://www.leadtools.com/SDK/Document/Document-Addon-OCR.htm , but it`s not for free .
(There is a "Image OCR Control" at msdn, but how can I get it?)

What I want to do: Find out if in a picture there is a smaller picture inside. (For example - in a picture where an striked off (??ausstreichenndes??) letter is , i can find out that there is a letter and what for a letter. All the letter are standart(not handwritten)).

P.S. Sorry about the english, but I just can`t write deutsch so good, but I understand everything.
P.S.S. This is one of the best delphi forums ever!
