java - 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);
   }
}

我正在尝试使用 OpenCV 3.0 在图像上制作水印，但 putText 有问题，我在互联网上搜索但没有解决方案。

错误信息是:

The method putText(org.opencv.core.Mat, java.lang.String, org.opencv.core.Point, int, double, org.opencv.core.Scalar) in the type Imgproc is not applicable for the arguments (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，如上所示的信息。我该如何解决这个问题？

Answer 1

错误信息已经说明了问题:

The method putText(org.opencv.core.Mat, java.lang.String, org.opencv.core.Point, int, double, org.opencv.core.Scalar) in the type Imgproc is not applicable for the arguments (org.opencv.core.Mat, java.lang.String, java.awt.Point, int, double, org.opencv.core.Scalar)

确保将点作为 org.opencv.core.Point 而不是 java.awt.Point 传递给 putText。
