The IsMultiThreadedSupported Property is available as an add-on to the LEADTOOLS Document and Medical Imaging toolkits.
Gets a value that indicates whether multi-threading is supported in this IOcrAutoRecognizeManager.
Syntax
| Visual Basic (Declaration) | |
|---|---|
ReadOnly Property IsMultiThreadedSupported As Boolean | |
| Visual Basic (Usage) |  Copy Code |
|---|---|
Dim instance As IOcrAutoRecognizeManager Dim value As Boolean value = instance.IsMultiThreadedSupported | |
| C# | |
|---|---|
bool IsMultiThreadedSupported {get;} | |
Property Value
(Read only) true if this IOcrAutoRecognizeManager supports multi-threading, otherwise; false.Example
Remarks
The IOcrAutoRecognizeManager supports converting a single document using multiple threads using the Run, IOcrAutoRecognizeManager.RunJob and IOcrAutoRecognizeManager.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 |
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.
