You can also use -
import java.awt.Rectangle;
public String ocrText(File file, String lang, ImageGeometry geometry) {
String resultText = null;
Tesseract instance = getTesseractInstance("TesseractEnvPath", "eng");
// define an equal or smaller region of interest on the image. Follow:
// x-scale, y-scale, width and height
Rectangle rect = new Rectangle(geometry.getXscale(), geometry.getYscale(),
geometry.getWidth(),
geometry.getHeight());
try {
resultText = instance.doOCR(ImageIO.read(file), rect);
log.debug("resultText: {}", resultText);
} catch (TesseractException | IOException e) {
e.printStackTrace();
}
return resultText;
}
