Hi Guys
We need a version of IEVision were we can execute the CreateOCR Function several times. We use it to extract text from images in a multithreaded environment. Is this possible ?? |

Hi
You can create it as often as you like, just ensure you null it between calls:
e_OCR := IEVisionLib.createOCR(':ENG');
e_OCR.recognize(ivw.IEBitmap.GetIEVisionImage(),IEVisionRect(ocrrect.x, ocrrect.y, ocrrect.width, ocrrect.height)).c_str();
e_OCR := nil;
e_OCR := IEVisionLib.createOCR('swedish');
e_OCR.recognize(ivw.IEBitmap.GetIEVisionImage(),IEVisionRect(ocrrect.x, ocrrect.y, ocrrect.width, ocrrect.height)).c_str();
e_OCR := nil;
e_OCR := IEVisionLib.createOCR('german');
e_OCR.recognize(ivw.IEBitmap.GetIEVisionImage(),IEVisionRect(ocrrect.x, ocrrect.y, ocrrect.width, ocrrect.height)).c_str();
e_OCR := nil;

Hi Nigel
Thank you for your reply. My Problem is that i cannot serialize it. The OCR recognition will be executed in several threads. When the User selects a file in the GUI, a thread will be executed to extract the text. When the User selects an Other file, a Second Thread will be executed. In this Case the recognition can work parallel.
That is my Problem. Ehen the Second Thread will be executed, i got an exception |

| At the moment the OCR engine is not thread-safe. Only one TIEVisionOCR can work for each thread. |
