Apache POI XWPF向标题添加形状 [英] Apache POI XWPF adding shapes to header

问题描述

我正在尝试将一些形状和徽标文件添加到我的单词docx文档的标题中。添加图片对我有用，但我找不到任何解决方法如何添加形状。任何人都可以帮助我吗？

I'm trying to add some shapes and a logo-file into the header of my word docx document. Adding a picture works for me, but i didn't find any solution how to add a shape. can anyone help me?

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

最后标题看起来像这个

谢谢

推荐答案

由于 apache poi XWPF 是直到现在才真正处于测试状态，只有在确切知道 Word 将如何将其内容存储到 XML 。然后可以解决 apache poi XWPF 的不足之处。您已经使用了这样的解决方法，当图片被添加到页眉或页脚中的运行时，它会更正错过的 blipID 。

Since the apache poi XWPF is really in beta state until now, such things are only possible if one knows exactly how Word will store it's contents into the XML. Then one can work around the inadequacies of apache poi XWPF. You have already used such a workaround which corrects the missed blipID when pictures are added to runs in header or footer.

要了解 Word 如何将其内容存储到 XML 中，这不是火箭科学。 *。docx 文件只是一个 ZIP 文件。如果使用Zip软件解压缩此文件，可以简单地查看XML文件。

To discover how Word will store it's contents into the XML is not rocket science. A *.docx file is simply a ZIP file. If one unzip this file using a Zip software, one can simply have a look into the XML files.

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

As far as I know adding shapes (in this case text boxes) in Word documents is not supported by apache poi directly. For this using the low level underlying objects (in this case CTGroupand CTShape) is needed.
