Java在Word中添加多行图片水印

import com.spire.doc.*;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.documents.TextWrappingStyle;
import com.spire.doc.fields.DocPicture;

public class ImageWatermark {
 public static void main(String[] args) {
  //加载Word文档
  Document doc=new Document();
  doc.loadFromFile("input.docx");

  //加载图片
  DocPicture picture = new DocPicture(doc);
  picture.loadImage("logo.png");
  picture.setTextWrappingStyle(TextWrappingStyle.Behind);//设置图片环绕方式

  //遍历所有section
  for (int n = 0; n < doc.getSections().getCount(); n++) {
   Section section = doc.getSections().get(n);

   //获取section的页眉
   HeaderFooter header = section.getHeadersFooters().getHeader();

   Paragraph paragrapg1;
   //获取或添加段落
   if(header.getParagraphs().getCount()>0)
   {
    paragrapg1 = header.getParagraphs().get(0);
   }
   else
    {
     paragrapg1 = header.addParagraph();
    }

   //复制图片，并添加图片到段落
   for (int p = 0; p < 4; p++) {
    for (int q = 0; q < 3; q++) {
     picture = (DocPicture)picture.deepClone();
     picture.setVerticalPosition(50 + 150 * p);
     picture.setHorizontalPosition(10 + 140 * q);
     paragrapg1.getChildObjects().add(picture);
    }
   }
  }

  //保存文档
  doc.saveToFile("output.docx", FileFormat.Docx_2013);
  doc.dispose();
 }
