putText在opencv3.0中不起作用

Question

import java.awt.Point;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.JFrame;
import org.opencv.core.Core;
import org.opencv.core.Mat;
import org.opencv.core.Scalar;
import org.opencv.core.Size;
import org.opencv.imgcodecs.Imgcodecs;
import org.opencv.imgproc.Imgproc;

public class Testingopencv 
{

   public static void main(String[] args) 
   {
      System.loadLibrary("opencv_java300");

      Mat src = Imgcodecs.imread("m.jpg");
      Mat temp = new Mat(src.rows(),src.cols(), src.type());

      Imgproc.putText(src, "Edited by me", new Point(src.rows()/2,src.cols()/2),
            Core.FONT_ITALIC, 1.0 ,new  Scalar(255));
      Imgcodecs.imwrite("watermarked.jpg", src);
   }
}

我试图使用OpenCV 3.0在图像上制作水印，但是putText有一个问题，我已经在网上搜索过了，但是没有解决方案。

错误信息是：

Imgproc类型中的putText(org.opencv.core.Mat、java.lang.String、org.opencv.core.Point、int、double、org.opencv.core.Scalar)方法不适用于参数(org.opencv.core.Mat、java.lang.String、java.awt.Point、int、double、org.opencv.core.Scalar)。

并且参数应该是正确的，如上面所示的消息。我怎么才能解决这个问题？

这个代码起作用了。

// Draw a bounding box around each face.
        for (Rect rect : faceDetections.toArray())
        {
            Core.rectangle(image, new Point(rect.x, rect.y), new Point(rect.x + rect.width, rect.y + rect.height), new Scalar(0, 255, 255));
            // for crop face
            rectCrop = new Rect(rect.x, rect.y, rect.width, rect.height);   

            Core.putText(image, "Edited by me", new Point(rect.x,rect.y),
                    Core.FONT_HERSHEY_PLAIN, 1.0 ,new  Scalar(0,255,255));
        }
