总结

前言

本文提供将图片进行色彩处理的Java工具类，让图片变成回忆中的画面。主要将图片做黑白与褐色的处理，具体的效果往下看吧。

环境依赖

一些工具的依赖，最好加一下。

        <dependency><groupId>com.google.guava</groupId><artifactId>guava</artifactId><version>30.1.1-jre</version></dependency><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.5.2</version></dependency>

ffmpeg环境依赖，需要添加一下。

可以直接参考我的另一篇文章安装：windows ffmpeg安装部署_阿良的博客-CSDN博客

代码

完整工具类代码如下

package ai.guiji.csdn.tools;import cn.hutool.core.util.IdUtil;
import com.google.common.base.Joiner;
import com.google.common.base.Splitter;import java.io.File;
import java.util.Arrays;
import java.util.List;/** @Author 剑客阿良_ALiang @Date 2021/11/19 18:09 @Description: 记忆中的图片 */
public class PictureInMemoryUtil {/*** 图片黑白化** @param imagePath 图片路径* @param outputDir 临时目录* @return 图片地址* @throws Exception 异常*/public static String blackAndWhite(String imagePath, String outputDir) throws Exception {List<String> paths = Splitter.on(".").splitToList(imagePath);String ext = paths.get(paths.size() - 1);if (!Arrays.asList("png", "jpg").contains(ext)) {throw new Exception("format error");}String resultPath =Joiner.on(File.separator).join(Arrays.asList(outputDir, IdUtil.simpleUUID() + "." + ext));ProcessBuilder builder =new ProcessBuilder("C:\\ffpg\\bin\\ffmpeg.exe","-i",imagePath,"-vf","colorchannelmixer=.3:.4:.3:0:.3:.4:.3:0:.3:.4:.3","-y",resultPath);builder.inheritIO().start().waitFor();return resultPath;}/*** 图片褐色化** @param imagePath 图片路径* @param outputDir 临时目录* @return 图片地址* @throws Exception 异常*/public static String brown(String imagePath, String outputDir) throws Exception {List<String> paths = Splitter.on(".").splitToList(imagePath);String ext = paths.get(paths.size() - 1);if (!Arrays.asList("png", "jpg").contains(ext)) {throw new Exception("format error");}String resultPath =Joiner.on(File.separator).join(Arrays.asList(outputDir, IdUtil.simpleUUID() + "." + ext));ProcessBuilder builder =new ProcessBuilder("C:\\ffpg\\bin\\ffmpeg.exe","-i",imagePath,"-vf","colorchannelmixer=.393:.769:.189:0:.349:.686:.168:0:.272:.534:.131","-y",resultPath);builder.inheritIO().start().waitFor();return resultPath;}}

代码说明

1、两个方法分别可以将图片黑白化和褐色化，参数均为：图片地址、输出目录。

2、两个方法中的ffmpeg执行路径，需要填写你安装ffmpeg的ffmpeg.exe所在位置。

3、两个方法均做了格式校验，只有两种，可按照自己的需求添加。

4、为了防止文件名重复，使用uuid作为文件名。

验证一下

下面是我选择的原始图片

验证代码如下

  public static void main(String[] args) throws Exception {System.out.println(blackAndWhite("C:\\Users\\huyi\\Desktop\\5.jpg", "C:\\Users\\huyi\\Desktop"));System.out.println(brown("C:\\Users\\huyi\\Desktop\\5.jpg", "C:\\Users\\huyi\\Desktop"));}

执行结果
