Gets or sets a value that indicates the maximum number of threads to use when recognizing a document.
public int MaximumThreadsPerJob { get; set; }
Property MaximumThreadsPerJob As Integer
@property (nonatomic, assign) NSInteger maximumThreadsPerJob
public int getMaximumThreadsPerJob()
public void setMaximumThreadsPerJob(int value)
An Int32 value that indicates the maximum number of threads to use when recognizing a document. Must be greater than or equals to 0 and less than or equals to 64. Default value is 0.
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.
The LEADTOOLS OCR Module - LEAD Engine uses the system thread pool and does not require a set number of threads. A value of 1 will disable threading and any other value will be treated as "use multi-threading".
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.LEAD/> Win32 (x86) version | Yes |
OcrEngineType.LEAD/> x64 version | Yes |
OcrEngineType.OmniPage/> Win32 (x86) version | Yes |
OcrEngineType.OmniPage/> 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.
