基于Java实现修改图片分辨率示例代码基于Java实现修改图片分辨率示

前言
环境依赖
代码
验证一下

前言本文提供可以修改图片分辨率的java工具类，实用主义的狂欢。

环境依赖添加必要的一些maven依赖。

cn.hutoolhutool-all5.7.15com.google.guavaguava31.0.1-jreorg.bytedecojavacv-platform1.5.5

代码不废话，上代码。

import cn.hutool.core.util.IdUtil; import com.google.common.base.Joiner; import com.google.common.base.Splitter; import org.bytedeco.javacpp.Loader; import java.io.File; import java.text.MessageFormat; import java.util.Arrays; import java.util.List; /** * @Program: csdn @ClassName: ModifyImageResolution @Author: 剑客阿良_ALiang @Date: 2021-12-12 * 13:37 @Description: 修改图片分辨率 @Version: V1.0 */public class ModifyImageResolution {/*** 修改图片分辨率** @param imagePath 原图片地址* @param outputDir 输出目录* @param width 宽度* @param height 高度* @return 图片地址* @throws Exception 异常*/public static String modifyResolution(String imagePath, String outputDir, Integer width, Integer height) throws Exception {List paths = Splitter.on(".").splitToList(imagePath); String ext = paths.get(paths.size() - 1); if (!Arrays.asList("jpg", "png").contains(ext)) {throw new Exception("format error"); }String resultPath =Joiner.on(File.separator).join(Arrays.asList(outputDir, IdUtil.simpleUUID() + "." + ext)); String ffmpeg = Loader.load(org.bytedeco.ffmpeg.ffmpeg.class); ProcessBuilder builder =new ProcessBuilder(ffmpeg,"-i",imagePath,"-vf",MessageFormat.format("scale={0}:{1}", String.valueOf(width), String.valueOf(height)),resultPath); builder.inheritIO().start().waitFor(); return resultPath; } }

代码说明：
1、modifyResolution方法入参分别为：原图片路径、输出目录地址、调整宽度、调整高度。
2、图片格式校验只有jpg、png，可以自行添加。
【基于Java实现修改图片分辨率示例代码】3、输出文件名避免重复使用uuid作为文件名。

验证一下准备的图片如下：

执行代码：

public static void main(String[] args) throws Exception {System.out.println(modifyResolution("C:\\Users\\yi\\Desktop\\2053767.jpg", "C:\\Users\\yi\\Desktop", 1280, 720)); }

执行结果：
