docx4j를 사용하여 docx를 조작하고 있습니다. 무엇을 하려는지 모든 테이블의 모든 이미지의 버퍼링 된 이미지를 만드는 것입니다. org.docx4j.wml.Drawing의 인스턴스가 있는데 거기에서 버퍼링 된 이미지를 만들 수있는 방법이 있습니까?Docx4j 버퍼 이미지
소스 코드는 대부분 어딘가에서 다운로드됩니다.
만 관련 부분 :
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);
}
이 기본적으로 표의 셀을 통해 이동하고 텍스트 나 그림
내가 사진에서 BufferedImage의를 만들고 싶어 wherther 결정합니다.
완전한 소스 코드 :
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");
}
}
}
}
}
이 방법은 셀에있는 모든 이미지를 불러 내가 믿는 부분을 찾기 위해 시도한다됩니다 :

나는 RLY 필사적 받고 몇 가지 방법과 메신저를 추가하는 시도 버퍼링 된 이미지로 변환 할 수 있습니다.
그러나 Part를 JAXBElement로 변환하는 다음 메소드는 항상 null을 반환합니다.
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;
}
이것은 엄청난 양의 코드입니다. 나는 많은 사람들이 그것을 읽지 않을지 의심 스럽다. 관련 부분으로 축소 할 수 있습니까? – marko
