POI XWPF: how to copy a picture from one XWPFDocument to another
Hello,
I want to append one XWPF document to another main document. I am going through all BodyElements in the document and copying every BodyELement to the main document.
The problem with my current approach is that the getElementType() only returns "PARAGRAPH" or "TABLE". If a pragraph contains a picture (PNG), it seems that the the picture cannot be copied over using setParagraph() method (please see my code block in below).
Would anyone advise how to copy a picture from one XWPFDocument to another? I am new to the XWPF API, or is there any better way to append one document to another? Thanks in advance.
Best regards,
ShuiChen
// start of code block
XWPFDocument doc = new XWPFDocument(new FileInputStream(appFile));
XWPFDocument maindDoc = new XWPFDocument(new FileInputStream(mainFile));
List elementList = doc.getBodyElements();
List paragraphList = doc.getParagraphs();
List tableList = doc.getTables();
for (int i = 0; i < elementList.size(); i++){
IBodyElement element = (IBodyElement) elementList.get(i);
if (element.getElementType().toString().equals("PARAGRAPH")) {
// copying the paragraph to the main document
paragraph = mainDoc.createParagraph();
paragraph = (XWPFParagraph) paragraphList.get(doc.getParagraphPos(i));
mainDoc.setParagraph(paragraph, doc.getParagraphPos(i));
} else if (element.getElementType().toString().equals("TABLE")) {
XWPFTable table = (XWPFTable) tableList.get(doc.getTablePos(i));
// copying the table to the main document
table = mainDoc.createTable();
table = (XWPFTable) tableList.get(doc.getTablePos(i));
mainDoc.setTable(doc.getTablePos(i), table);
}
}
// end of code block

Hi,
Can anyone help? I am not sure if it's possible to append two Word documents using POI, I really appreciate if anyone could point me to the right direction?
Kind regards,
