All Implemented Interfaces:

Serializable

public class TesseractOCRConfig
extends Object
implements Serializable

Configuration for TesseractOCRParser. This allows to enable TesseractOCRParser and set its parameters:

TesseractOCRConfig config = new TesseractOCRConfig();
config.setTesseractPath(tesseractFolder);
parseContext.set(TesseractOCRConfig.class, config);

Parameters can also be set by either editing the existing TesseractOCRConfig.properties file in, tika-parser/src/main/resources/org/apache/tika/parser/ocr, or overriding it by creating your own and placing it in the package org/apache/tika/parser/ocr on the classpath.
