水印代码java 水印代码是什么( 二 )

section.getDocument().setWatermark(txtWatermark);
}
}
2.添加图片水印——代码如下水印代码java：
import com.spire.doc.*;
public class WordImageWatermark {
public static void main(String[] args)throws Exception{
Document document = new Document();
document.loadFromFile("Sample.docx");
PictureWatermark picture = new PictureWatermark();
picture.setPicture("logo.png");
picture.setScaling(5);
picture.isWashout(false);
document.setWatermark(picture);
document.saveToFile("out/result2.docx",FileFormat.Docx )
}
}
