java - Apache POI XWPF 添加形状到标题

Question

我正在尝试将一些形状和 Logo 文件添加到我的 word docx 文档的标题中。添加图片对我有用，但我没有找到任何如何添加形状的解决方案。谁能帮助我吗？

String imgFile="logo.png";

XWPFDocument document = new XWPFDocument(new FileInputStream("myfile.docx"));

CTSectPr sectPr = document.getDocument().getBody().addNewSectPr();

XWPFHeaderFooterPolicy headerFooterPolicy = new XWPFHeaderFooterPolicy(document, sectPr);               
XWPFHeader header = headerFooterPolicy.createHeader(XWPFHeaderFooterPolicy.DEFAULT);

XWPFParagraph paragraph = header.getParagraphArray(0);
paragraph.setAlignment(ParagraphAlignment.CENTER);

XWPFRun run = paragraph.createRun();
XWPFPicture picture = run.addPicture(new FileInputStream(imgFile), XWPFDocument.PICTURE_TYPE_PNG, imgFile, Units.toEMU(195), Units.toEMU(22));

String blipID = "";
for(XWPFPictureData picturedata : header.getAllPackagePictures()) {
  blipID = header.getRelationId(picturedata);
}
picture.getCTPicture().getBlipFill().getBlip().setEmbed(blipID); //now they have a blipID too

最后， header 应类似于 this

谢谢

由于 apache poi XWPF 到目前为止确实处于测试状态，因此只有确切知道 Word 将如何存储这些事情才有可能它的内容到 XML 中。然后就可以解决 apache poi XWPF 的不足之处。您已经使用过这样的解决方法，可以在将图片添加到页眉或页脚中时纠正丢失的 blipID。

了解 Word 如何将其内容存储到 XML 中并不是什么复杂的事情。 *.docx 文件只是一个 ZIP 文件。如果使用 Zip 软件解压缩该文件，则可以简单地查看 XML 文件。

据我所知，apache poi 不直接支持在 Word 文档中添加形状(在本例中为文本框)。为此，需要使用低级底层对象(在本例中为 CTGroup 和 CTShape)。
