前面我们介绍了如何使用 Spire.Doc for Java 添加多行文本水印到 Word 文档。该文将详细介绍在Word页眉中添加多行图片水印的效果。

import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.HeaderFooter;
import com.spire.doc.Section;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.documents.TextWrappingStyle;
import com.spire.doc.fields.DocPicture;

public class WordImageWatermark {
    public static void main(String[] args) throws Exception {
        //加载示例文档
        Document doc=new Document();
        doc.loadFromFile("Sample.docx");
        //加载图片
        DocPicture picture = new DocPicture(doc);
        picture.loadImage("Logo.png");

        //设置图片环绕方式
        picture.setTextWrappingStyle(TextWrappingStyle.Behind);

        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;
            if(header.getParagraphs().getCount()>0){
                paragrapg1=header.getParagraphs().get(0);

            }else {
                //添加段落到页眉
                paragrapg1 = header.addParagraph();
            }

            for (int p = 0; p < 3; p++) {

                for (int q = 0; q < 2; q++) {
                    //复制图片并设置多行多列位置
                    picture = (DocPicture)picture.deepClone();
                    picture.setVerticalPosition(100 + 200 * p);
                    picture.setHorizontalPosition(50 + 210 * q);
                    paragrapg1.getChildObjects().add(picture);
                }
            }
        }
        //保存文档
        doc.saveToFile("多行图片水印.docx", FileFormat.Docx_2013);
    }
}
