I am trying to take an image and extract hand written text so that it can be read easily and zoomed in on. I would like to convert the text to vector paths.
我正在尝试取一个图像并提取手写文本，这样它就可以很容易地阅读和放大。我想把文本转换成向量路径。
I am not aware of any libraries that would make this as painless as possible. Any help is greatly appreciated. Examples are nice too :)
我不知道是否有任何库可以使这个过程尽可能的不痛苦。非常感谢您的帮助。例子也不错:

The only program I know of for the iPhone that does handwriting recognition is HWPEN. Unfortunately, it's not a library but a full application and (to make matters worse) it requires a Jailbroken phone.
据我所知，iPhone上唯一一个能进行手写识别的程序是HWPEN。不幸的是，它不是一个库，而是一个完整的应用程序，(更糟糕的是)它需要一个越狱电话。
I fear you must either try to get the source for HWPEN or reverse engineer it to obtain the code you need.
我担心，您要么尝试获取HWPEN的源代码，要么将其逆向工程，以获得您需要的代码。
Barring that, you may want to write your own. There are several studies on handwriting recognition that may help.
除此之外，你可以自己写。有几项关于笔迹识别的研究可能会有所帮助。
