- EnableLanguageDetection
Gets or sets a value indicating whether automatic language detection should be performed before OCR.
Default:
true
- EnableModelDownload
When true, automatically downloads missing Tesseract traineddata files from the Hugging Face repository if they are not present locally.
Default:
true
- EnableOrientationDetection
Gets or sets a value indicating whether automatic orientation detection should be performed before OCR.

true
Methods
- Dispose()
Releases all resources used by this instance.
- RunAsync(OcrParameters, CancellationToken)
Runs OCR on the provided image data asynchronously.
Events
- LanguageDetected
Occurs when a language is detected during OCR processing, typically when EnableLanguageDetection is enabled. Subscribers can use this callback to inspect or log the detected Language before the OCR engine proceeds.
- OrientationDetected
Occurs when an orientation is detected during OCR processing. Subscribers receive the rotation angle (in degrees).
