问题描述

我一直在审查Office 2007 MODI OCR的替代产品(OneNote 2010解决方案的质量/结果低于2007年:/().我注意到，一旦安装

I have been reviewing replacements for the Office 2007 MODI OCR (OneNote's 2010 solution has lesser quality/results than 2007 :-( ). I notice that Windows 7 contains an OCR library once you install the optional tiff filter

OCR组件已安装到

%programfiles%\Common Files\microsoft shared\OCR\7.0\xocr3.psp.dll 

但是我没有看到任何API吗?

but I don't see any API for it?

有人看到如何最好在C#中进行接口吗?

Does anyone see how this can be interfaced preferably in C#?

答案:找到了解决方法，一旦安装了可选的tiff ifilter win7功能，我就可以使用

ANSWER: Found the soluation, once the optional tiff ifilter win7 feature is installed, i can then get a textoutput of a screenshot using the code/exe on http://www.codeproject.com/KB/cs/IFilter.aspx. Also if add the same [HKEY_CLASSES_ROOT.tiff\PersistentHandler] for .png and .jpg then OCR also works for jpg and png's.
