int MaximumThreadsPerJob {get; set;}
'Declaration Property MaximumThreadsPerJob As Integer

Object.defineProperty('MaximumThreadsPerJob');
A value of 0 means use maximum number of CPUs/cores available to the machine. The engine will read this value from System.Environment.ProcessorCount.
The IOcrAutoRecognizeManager supports converting a single document using multiple threads using the Run, RunJob and RunJobAsync methods. You can enable this feature by setting MaximumThreadsPerJob to 0 (for maximum CPUs/cores) or a value greater than 1.
Not all OCR engines support multi-threading in this fashion. If multi-threading supported, then IsMultiThreadedSupported will be true and the value of MaximumThreadsPerJob is used.
If the OCR engine does not support multi-threading, then IsMultiThreadedSupported will be false and the value of MaximumThreadsPerJob is not used (ignored).
The following table lists the LEADTOOLS OCR engines and whether they support multi-threading in IOcrAutoRecognizeManager:
OCR Engine |
Multi-threaded supported in IOcrAutoRecognizeManager |
---|---|
OcrEngineType.Advantage/> Win32 (x86) version | Yes |
OcrEngineType.Advantage/> x64 version | Yes |
OcrEngineType.Professional/> Win32 (x86) version | Yes |
OcrEngineType.Professional/> x64 version | No |
OcrEngineType.Plus/> Win32 (x86) version | No |
OcrEngineType.Plus/> x64 version | No |
OcrEngineType.Arabic/> Win32 (x86) version | No |
OcrEngineType.Arabic/> x64 version | No |
Note: This property is not used and will be ignored when using engine native format (DocumentFormat.User and IOcrDocumentManager.EngineFormat).
Some OCR engine types support creating multi-threaded documents by creating one IOcrEngine and multiple IOcrDocument or IOcrAutoRecognizeJob each in its own dedicated threads. For more information, refer to Multi-Threading with LEADTOOLS OCR.
