tess4j: Read text in rectangle of image

[Dattatraya Tembare]

I wrote this piece of code:

public static void main(String[] args) {
 String fileStr = "C:/EA/mp-out/im/1/3/1-0.png";
 File file = new File(fileStr);
 //380x45+220+170
 int xsize = 220;
 int ysize = 170;
 BufferedImage bufImage;
 ByteBuffer buf = null;
 try {
 bufImage = ImageIO.read(file);
 IIOImage image=new IIOImage(bufImage,null,null);
 buf = ImageIOHelper.getImageByteBuffer(image);
 } catch (IOException e2) {
 e2.printStackTrace();
 }
 Rectangle rect = new Rectangle(0, 0, 380, 45); // define an equal or smaller region of interest on the image
 int bpp = 8; //Gray=8, RGB=24
 
 Tesseract in = new ReadImageText().getTesseractInstance("C:/Program Files (x86)/Tesseract-OCR/tessdata/", "eng");
 try {
 String resultText = in.doOCR(xsize, ysize, buf, "C:/Program Files (x86)/Tesseract-OCR/tessdata/hin.traineddata", rect, bpp);
 log.info("resultText: {}", resultText);
 } catch (TesseractException e) {
 e.printStackTrace();
 }
 }

Result: Not sure what am I missing?
