Hi!
i am stucked in a confusing problem. i have a captcha image i want to create an app that separate every character of that captcha and save it as bmp image. anyone have an idea how to perform it...?

推荐答案

好吧，第一个问题是，验证码的整个想法是:机器找不到或说出字符是什么.因此，或者您将要处理垃圾验证码(在这种情况下，可以使用ReCaptcha，它是免费的，还可以帮助数字化图书)，或者您必须始终提供手动输入.

那么，这到底有什么意义?

Well, the first problem is, that the whole idea of captcha is: machines can''t find or tell what the characters are. So either you will be dealing with a rubbish captcha - in which case look at using ReCaptcha instead, it''s free, and also helps digitise books - or you will have to provide manual input at all times.

So, what is the point of this exactly?
