我使用docx4j来操作docx。我想要做的是在所有表格中制作每张图像的缓冲图像。我有org.docx4j.wml.Drawing的实例，有没有办法从中制作缓冲图像？
源代码大多是从某个地方下载的。
仅限相关部分：
for (Object o : children ) {
System.out.println(" " + o.getClass().getName() );
if ( o instanceof javax.xml.bind.JAXBElement) {
System.out.println(" " + ((JAXBElement)o).getName() );
System.out.println(" " + ((JAXBElement)o).getDeclaredType().getName());
// TODO - unmarshall directly to Text.
if ( ((JAXBElement)o).getDeclaredType().getName().equals("org.docx4j.wml.Text") ) {
org.docx4j.wml.Text t = (org.docx4j.wml.Text)((JAXBElement)o).getValue();
System.out.println(" " + t.getValue() );
} else if ( ((JAXBElement)o).getDeclaredType().getName().equals("org.docx4j.wml.Drawing") ) {
org.docx4j.wml.Drawing d = (org.docx4j.wml.Drawing)((JAXBElement)o).getValue();
describeDrawing(d);
}
这将基本上通过表中的单元格来确定其文本或图片
我想从照片中制作缓冲图像。

我尝试添加一些方法并且我变得非常绝望：
private static void bordel(org.docx4j.wml.Drawing d){
MainDocumentPart documentPart = wordMLPackage.getMainDocumentPart();
RelationshipsPart relsPart = documentPart.getRelationshipsPart();
Relationships rels = relsPart.getRelationships();
List<Relationship> relsList = rels.getRelationship();
for (Relationship r : relsList) {
JAXBElement el = printInfo(relsPart.getPart(r));
if (el != null) {
if ( el.getDeclaredType().getName().equals("org.docx4j.wml.Drawing") ) {
org.docx4j.wml.Drawing c = (org.docx4j.wml.Drawing) el.getValue();
if (c.equals(d)){
System.out.println( "I found part");
}
}
}
}
}
在单元格中的每个图像上调用此方法，并尝试找到我认为可以转换为bufferedimage的Part
但是将Part转换为JAXBElement的下一个方法总是返回null
public static JAXBElement printInfo(Part p) {
JAXBElement el = null;
if (p instanceof JaxbXmlPart) {
Object o = ((JaxbXmlPart)p).getJaxbElement();
if (o instanceof javax.xml.bind.JAXBElement) {
//sb.append(" containing JaxbElement:" + XmlUtils.JAXBElementDebug((JAXBElement)o) );
el= (JAXBElement) o;
} else {
//sb.append(" containing JaxbElement:" + o.getClass().getName() );
}
}
return el;
}
答案 0 :(得分：0)
以下代码将为您找到图像关系：
BlipFinder bf = new BlipFinder();
new TraversalUtil(paragraphs, bf);
for (CTBlip imageReference : bf.blips) {
if (imageReference.getLink() != null
&& !imageReference.getLink().equals("")) {
Relationship existingRel = docxPkg.getMainDocumentPart()
.getRelationshipsPart().getRelationshipByID(
imageReference.getLink());
:
} else if (imageReference.getEmbed() != null) {
String relId = imageReference.getEmbed();
Relationship r = docxPkg.getMainDocumentPart().getRelationshipsPart().getRelationshipByID(relId);
if (r.getTargetMode()!=null
&& r.getTargetMode().toLowerCase().equals("external")) {
:
} else {
BinaryPartAbstractImage oldPart = (BinaryPartAbstractImage)docxPkg.getMainDocumentPart().getRelationshipsPart().getPart(relId);
:
}
} else {
log.error("HELP! neither linked nor embedded?");
}
}
}
static class BlipFinder extends CallbackImpl {
List<CTBlip> blips = new ArrayList<CTBlip>();
@Override
public List<Object> apply(Object o) {
if (o instanceof CTBlip)
blips.add((CTBlip)o);
return null;
}
并在指定的情况下，给你一个BinaryPartAbstractImage。一旦你拥有了它，你可以做任何你喜欢的事情......
