c# - Are there any free .NET OCR libraries that will perform OCR on an application window directly? -

I am a free one. Looking for the NET OCR library which can take the OCR in a given app window or an image memory (I can take a snapshot of the app window myself).

I have seen and both require an image located on the disk.

I need to use OCR because the application I am trying to write a script, which is something weird that the windows API can not be read and I scrap the data from the screen need to. I tested both and they both stories can often read, but because it will not be able to write to disk will be running in an environment, I need it, he can read directly from Apisiliti window or some sort Memory Stream .

I am thinking that OCR is my only accident, but I can not even think of other ways.

Suggestions?

Edit on the basis of comments: The environment is a C # .NET Windows application without any disk access. This is an application that code is collected and executed, and this code is in context, which should not require any resource other than memory.

As the test page I can see from the library requires a bitmap, So what if you make it with the method?

You can create a bitmap object with this constructor:
