实践一下比对两张图片的差异并标注保存到另一张图片
项目pom采用：https://github.com/romankh3/image-comparison
实践参考文献：https://blog.csdn.net/haiyangyiba/article/details/131631195
1.新建java maven项目
导入依赖

<dependency>
            <groupId>com.github.romankh3</groupId>
            <artifactId>image-comparison</artifactId>
            <version>4.4.0</version>
</dependency>

2.代码准备

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

        test01();
    }

    private static void test01() {
        //加载图片
        BufferedImage expectedImage = ImageComparisonUtil.readImageFromResources("Expected.png");
        BufferedImage actualImage = ImageComparisonUtil.readImageFromResources("Actual.png");
        //对比两个图片
        ImageComparisonResult imageComparisonResult = new ImageComparison(expectedImage, actualImage).compareImages();
        String folder = ImageComparisonUtil.class.getClassLoader().getResource("").getPath();
        //存储图片和输出结果
        ImageComparisonUtil.saveImage(new File(folder , "Github图片对比结果.png") , imageComparisonResult.getResult());
        System.out.println("Github图片对比状态：" + imageComparisonResult.getImageComparisonState());
    }
}

3.resources下准备两张图片，用的开源项目给的那两张
4.运行代码，可以看到差异图片生成在了target下

图片有两处差异，都用矩形标注出来了
