import org.opencv.imgproc.Imgproc;

public class AddingTextToImage {
   public static void main(String args[]) {

      //Loading the OpenCV core library
      System.loadLibrary( Core.NATIVE_LIBRARY_NAME );

      //Reading the Image from the file and storing it in to a Matrix object
      String file = "C:/opencv/logo.jpg";
      Mat matrix = Imgcodecs.imread(file);

      //Adding Text
