We already shared the code example to extract the images from the document. You do not need to merge shapes of paragraph. Please check the code example shared in following post.

Thanks for your reply.
We are using preclean up process so that i need to merge shapes paragraph please provide some solution for above mentioned requirement with the help of same sample documents.

@jan.kathir

Please iterate over paragraph nodes and get the paragraphs before Fig caption. You can use following method to merge the paragraphs. Hope this helps you.

public static void mergeParagraphs(Paragraph dstPar, Paragraph srcPar)
{
    //move all content from source paragraph into the destination paragraph
    while (srcPar.hasChildNodes())
        dstPar.appendChild(srcPar.getFirstChild());

    //Remove source paragraph
    srcPar.remove();
}

Document doc = new Document(MyDir + "Chp_38.doc");

DocumentBuilder builder = new DocumentBuilder(doc);
int bm = 1;
ArrayList nodes = new ArrayList();

for (Paragraph  paragraph : (Iterable<Paragraph>) doc.getChildNodes(NodeType.PARAGRAPH, true))
{
    if(paragraph.toString(SaveFormat.TEXT).trim().startsWith("Fig"))
    {
        Node previousPara = paragraph.getPreviousSibling();
        while (previousPara != null
                && previousPara.getNodeType() == NodeType.PARAGRAPH
                && previousPara.toString(SaveFormat.TEXT).trim().length() == 0)
        {
            previousPara = previousPara.getPreviousSibling();
        }

        builder.moveTo(previousPara);
        builder.startBookmark("bookmark" + bm);
        builder.moveTo(paragraph);
        builder.endBookmark("bookmark" + bm);
        bm++;
    }
}
doc.updatePageLayout();
for(Bookmark bookmark : doc.getRange().getBookmarks())
{
    if(!bookmark.getName().startsWith("bookmark"))
        continue;

    Node node = bookmark.getBookmarkStart();

    while (node != bookmark.getBookmarkEnd())
    {
        node = node.nextPreOrder(doc);

        if(node.getNodeType() == NodeType.PARAGRAPH)
            nodes.add(node);
    }
    merge_Paragraphs(nodes);
    nodes.clear();
}
doc.save(MyDir + "20.4.docx");

public static void merge_Paragraphs(ArrayList nodes)
{
    Paragraph dstPar = (Paragraph) nodes.get(0);
    for(int j = 1; j < nodes.size(); j++)
    {
        Paragraph srcPar = (Paragraph) nodes.get(j);
        //move all content from source paragraph into the destination paragraph
        while (srcPar.hasChildNodes())
            dstPar.appendChild(srcPar.getFirstChild());

        //Remove source paragraph
        srcPar.remove();
    }
