在Java语言编程中，如何使用Java(读/写)读取复制和粘贴图片？
注意：需要访问网址： ， 下载一个OpenCV软件包。这里下载最新版本：opencv-3.2.0-vc14.exe并解压此文件到D:softwareopencv目录中。
项目结构如下图所示 –
添加一个用户自定义库：OpenCV3.2，并指配置构建路径为：D:softwareopencvopencvbuildjavax64，如下图所示 –
注：可参考：
以下是使用Java复制和粘贴图像的程序 –
package com.yiibai;    import org.opencv.core.Core;  import org.opencv.core.Mat;  import org.opencv.imgcodecs.Imgcodecs;    // opencv-3.2.0.jar 下载地址：http://github.com/opencv/opencv/releases/tag/3.3.0    public class CopyAndPasteAnImage {      public static void main(String args[]) {          String propath = System.getProperty("user.dir");          System.out.println(propath);          // 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 = propath+"/images/mydog.jpg";            Mat matrix = Imgcodecs.imread(file);          System.out.println("Image Loaded ..........");          String file2 = propath+"/images/mydogResaved.jpg";            // Writing the image          Imgcodecs.imwrite(file2, matrix);          System.out.println("Image Saved ............");      }  }
执行上面示例代码，得到以下结果 –
F:workspjavaexamplesjava_opencv  Image Loaded ..........  Image Saved ............
在执行上面示例代码成功后，应该会在 F:workspjavaexamplesjava_opencvimages 目录中有看到生成一个文件：mydogResaved.jpg 。
问题
F:workspjavaexamplesjava_opencv  Exception in thread "main" java.lang.UnsatisfiedLinkError: no opencv_java320 in java.library.path      at java.lang.ClassLoader.loadLibrary(Unknown Source)      at java.lang.Runtime.loadLibrary0(Unknown Source)      at java.lang.System.loadLibrary(Unknown Source)      at com.yiibai.CopyAndPasteAnImage.main(CopyAndPasteAnImage.java:13)
解决上述问题可通过参考：
