前面我们介绍了如何使用 Spire.Doc for Java 添加文本水印和图片水印到 Word 文档。该文将详细介绍在Word页眉中添加艺术字实现Word文档中多行文字水印效果。

添加多行文本水印：

import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.ShapeObject;

import java.awt.*;

public class WordWatermark {
    public static void main(String[] args) {
        //加载示例文档
        Document doc = new Document();
        doc.loadFromFile("Sample.docx");
        //添加艺术字并设置大小
        ShapeObject shape = new ShapeObject(doc, ShapeType.Text_Plain_Text);
        shape.setWidth(60);
        shape.setHeight(20);
        //设置艺术字文本内容、位置及样式
        shape.setVerticalPosition(30);
        shape.setHorizontalPosition(20);
        shape.setRotation(315);
        shape.getWordArt().setFontFamily("宋体");
        shape.getWordArt().setText("内部使用");
        shape.setFillColor(Color.red);
        shape.setLineStyle(ShapeLineStyle.Single);
        shape.setStrokeColor(new Color(192, 192, 192, 255));
        shape.setStrokeWeight(1);

        Section section;
        HeaderFooter header;
        for (int n = 0; n < doc.getSections().getCount(); n++) {
            section = doc.getSections().get(n);
            //获取section的页眉
            header = section.getHeadersFooters().getHeader();
            Paragraph paragraph;

            if (header.getParagraphs().getCount() > 0) {
                //如果页眉有段落，取它第一个段落
                paragraph = header.getParagraphs().get(0);
            } else {
                //否则新增加一个段落到页眉
                paragraph = header.addParagraph();
            }
            for (int i = 0; i < 4; i++) {
                for (int j = 0; j < 3; j++) {
                    //复制艺术字并设置多行多列位置
                    shape = (ShapeObject) shape.deepClone();
                    shape.setVerticalPosition(50 + 150 * i);
                    shape.setHorizontalPosition(20 + 160 * j);
                    paragraph.getChildObjects().add(shape);
                }
            }
        }
        //保存文档
        doc.saveToFile("result.docx", FileFormat.Docx_2013);
    }
}
