Methods

	Name	Description
	ClearResults	Free up recognition results and any stored image data, without actually freeing any recognition data that would be time-consuming to reload such as language dictionaries.
	Close
	DetectOrientationAndScript(String)	Detects the orientation and script of a document image.
	DetectOrientationAndScript(Int32, Int32, Int32)	Detects the orientation and script of a document image.
	DoOcrAsync(TesseractOcrJobRequest, String)	Executes an instance (job) of the OCR engine over the image file stored in 'filename' with the specified settings present in the TesseractOcrJobRequest in an Asynchronous way, preventing blocking of the main thread.
	DoOcrAsync(TesseractOcrJobRequest, Int32, Int32, Int32)	Executes an instance (job) of the OCR engine over the image raw specified by pixelWidth, pixelHeight and Pixels, with the specified settings present in the TesseractOcrJobRequest in an Asynchronous way, preventing blocking of the main thread.
	DoOcrAsync(TesseractOcrJobRequest, Int32, Int32, IBuffer)	Executes an instance (job) of the OCR engine over the image raw specified by pixelWidth, pixelHeight and pixelBuffer, with the specified settings present in the TesseractOcrJobRequest in an Asynchronous way, preventing blocking of the main thread.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetLastJobInternalBitmap(Int32)	Fills a WriteableBitmap with the thresholded image used internally in the previous ocr job.
	GetLastJobInternalBitmap(IBuffer)	Fills a WriteableBitmap with the thresholded image used internally in the previous ocr job.
	GetLastJobInternalBitmapDimensions	Gets the dimensions of the internal image that was used by the OCR engine in the previous job.
	GetTesseractEngineVersion	Gets the tesseract engine version.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InitializeEngine	Initializes the OCR engine with the language dictionary.
	SetLicense	Sets the license information.
	ShutdownEngine	Close down the engine and free up all memory.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Events

	Name	Description
	AutoDeskewCompleted	Raised after the Auto Deskew image pre-processing completed.
	AutoOrientationDetected	Raised after the Automatic detection of the document orientation.
	BeforeRecognition	Raised just before the ocr engine start recognizing text and layout.
	JobCanceled	Raised when the Ocr job was canceled.
	JobCompleted	Raised when the Ocr job completed.
	JobStarted	Raised when the Ocr job started.

Remarks

Please make sure that you don't use a global variable to control the engine. The TesseractOcrEngine is actualy an instance for running a ocr job, and you should initialize it and destroy it per OCR job. So remember to not share it globally.
