A: Java using Google's Thumbnailator tool to compress images, such as image processing

Thumbnailator is a very good picture of how to use open Source tools: Add the following jar packages to the POM

<!--picture thumbnail image compression watermark start- 

<Dependency>
<groupId>Net.coobird</groupId>
<Artifactid>Thumbnailator</Artifactid>
<version>0.4.8</version>
</Dependency><!--picture thumbnail image compression watermark end -

Then the compression and watermark only need one line of code to fix

 package Com.shallowmemory.test;import net.coobird.thumbnailator.Thumbnails; Import Net.coobird.thumbnailator.geometry.positions;import Javax.imageio.imageio;import Java.awt.image.bufferedimage;import java.io.file;import java.io.ioexception;/*** Created by HONGLINCHEN on 2017/10/31 11:00* image compression * @author honglinchen* @since JDK 1.8*/public class Imgcompress {public static void main (string[] args) throws IOException {//Compress picture The first parameter is the path after the original path is the output path after compression thumbnails.of ("C:\Users\HONGLINCHEN\Desktop\23.jpg").
