Hi,

Is it possible to OCR a specific area of an Image file in v16?

My requirement : The user selects a rectangular area of an Image file using a tool ( from toolbar ). This area will be dragged and dropped into an edit box. Here, the text within the selected rectangular area is displayed.

I intend to make use of C DLL.

Thanks in advance..

You can try to do this by creating an OCR Zone on the image, so that the Zone dimensions equal the dimensions of the rectangular area. Now when you call the recognize method, the OCR engine will recognize only the area inside the Zone. You can add a new zone by using the L_Doc2AddZone function.

In case the selected area contains text in some language ( other than English ), I will need to explicitly set the correct language settings while ocring so that the correct text is retrieved to the edit box.
Is my understanding correct? Does LT v16.5 support this feature in a different way?

Kindly clarify.

Thanks...

Yes, you need to set the correct language settings before OCR the image.

About LEADTOOLS v16.5, LEADTOOLS v16.5 doesn't support this in a different way.

Which function do I need to use to retrieve the Ocred text? I would like to have a return type of WString to handle Unicode data.

Thanks.....

You can try to use the L_Doc2GetRecognizedWords function. This function gets all recognized words for the specified recognized page.
For more information, please refer to the help topic "L_Doc2GetRecognizedWords" in the LEADTOOLS OCR Document Imaging C DLL help file.

Thanks,
