Class TesseractEngineMode
Allows the developer to choose the algorithm Tesseract will use for OCR. TesseractAndLstm is the recommended behavior for IronOCR.
Inheritance
Namespace: IronOcr
Assembly: IronOcr.dll
Syntax
public sealed class TesseractEngineMode : EnumSelecting the recognition algorithm Tesseract runs sets TesseractConfiguration.EngineMode to a TesseractEngineMode value. TesseractAndLstm combines the legacy engine with the neural LSTM model and is the recommended mode for IronOCR, LstmOnly uses just the neural model, TesseractOnly uses just the legacy engine, and Default lets Tesseract pick. The Tesseract config how-to sets engine options.
ocr.Configuration.EngineMode = TesseractEngineMode.TesseractAndLstm;Fields
Default
The default OCR engine is used (currently LSTM-based OCR engine).
Declaration
public const TesseractEngineMode DefaultField Value
| Type | Description |
|---|---|
| TesseractEngineMode |
LstmOnly
Only the new LSTM-based OCR engine is used. Uses a pre programmed neural net. (Tesseract 4 + 5 Mode)

|---|---|
| TesseractEngineMode |
TesseractAndLstm
Both the legacy and new LSTM based OCR engine is used. (Recommended for a good balance of speed and performance)
