when to use ProcessPage

[Neha Mittal]

The way I have been using tesseract so far is 

p_ocr_obj = new tesseract::TessBaseAPI();

 p_ocr_obj->Init(...);

p_ocr_obj->SetImage( ... );

p_ocr_obj->GetUTF8Text();

For some images, tesseract takes more than a minute to give a result. Not sure why but I was thinking that maybe I can set a timeout when calling the tesseract api. 

I see the function ProcessPage where I can give a timeout value. 

So my question is, what what does ProcessPage actually do? Is the functionality different from what I already have?

Is there any other way to set a timeout for tesseract?
