Question

我正在使用docx4j api创建docx文件。我已成功将一个docx内容复制到了另一个。对于复制标题内容，我得到标题文本。但是我的要求也是复制标题图像。我怎样才能做到这一点？我正在使用下面的代码复制标题-

 WordprocessingMLPackage source = WordprocessingMLPackage.load(new File(
                        "D://PoC//Agenda Formats//test.docx"));
                RelationshipsPart rp = source.getMainDocumentPart()
                                .getRelationshipsPart();
 Relationship rel = rp.getRelationshipByType(Namespaces.HEADER);
 HeaderPart headerPart = (HeaderPart)rp.getPart(rel);
HeaderPart newHeaderPart = new HeaderPart();
newHeaderPart.setContents(XmlUtils.deepCopy(headerPart.getContents()));
return wordprocessingMLPackage.getMainDocumentPart().addTargetPart(
                                newHeaderPart, AddPartBehaviour.RENAME_IF_NAME_EXISTS);

，但是此代码不复制图像。任何帮助表示赞赏。

尝试类似（未经测试）的内容：

void attachHeader(HeaderPart sourcePart, WordprocessingMLPackage targetPkg) throws Docx4JException {

    HeaderPart newHeaderPart = new HeaderPart();
    newHeaderPart.setContents(XmlUtils.deepCopy(sourcePart.getContents()));

    if (sourcePart.getRelationshipsPart()!=null) {

        // clone the rels part
        RelationshipsPart rp = sourcePart.getRelationshipsPart();
        newHeaderPart.getRelationshipsPart(true).setContents(XmlUtils.deepCopy(rp.getContents()));

        // copy/add each part
        for (Relationship r : newHeaderPart.getRelationshipsPart().getContents().getRelationship()) {

            // get the source part
            Part part = sourcePart.getRelationshipsPart().getPart(r.getId());

            // ensure it is loaded
            if (part instanceof BinaryPart) {
                ((BinaryPart)part).getBuffer();
            }

            // You might need to clone this part depending on your use case, but here I'll just attach it to targetPkg              
            targetPkg.getParts().getParts().put(part.getPartName(), part);
                // This simple approach won't work if the target package already contains a part with the same name 
                // To fix that, you'd need to rename the part (also in the rel)

            part.setPackage(targetPkg);
            part.setOwningRelationshipPart(newHeaderPart.getRelationshipsPart());

        }

    }
    targetPkg.getMainDocumentPart().addTargetPart(newHeaderPart,
            AddPartBehaviour.RENAME_IF_NAME_EXISTS);        
}
