I. Java uses google's thumbnailator tool to process image compression watermarks,
Thumbnailator is a good open-source image tool: Add the following jar package to pom

<! -- Start -->

<Dependency>
<GroupId> net. coobird </groupId>
<ArtifactId> thumbnailator </artifactId>
<Version> 0.4.8 </version>
</Dependency> <! -- Image thumbnail image compression watermark end -->

 

Then, only one line of code is required for compression and watermarking.

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.
