有一份需要签名的word文件，需要签名的位置有多个。我需要解析文档内容，比如：签名____。当我获取到这个签名____时，能否获取这段内容在文档当前页的坐标位置？如果word无法实现的话，转换成pdf格式的文件能否实现？

@Maiden 您可以使用LayoutCollector和LayoutEnumerator类来获取文档中节点的布局信息。 例如以下代码获取文档中书签的布局信息：

Document doc = new Document("C:\\Temp\\in.docx");
LayoutCollector collector = new LayoutCollector(doc);
LayoutEnumerator enumerator = new LayoutEnumerator(doc);

// Get layout information of the bookmarks.
for (Bookmark bk : doc.getRange().getBookmarks())
{
    System.out.println("Bookmark name: " + bk.getName());
    System.out.println("Bookmark start page: " + collector.getStartPageIndex(bk.getBookmarkStart()));
    System.out.println("Bookmark end page: " + collector.getEndPageIndex(bk.getBookmarkEnd()));

    // Use LayoutEnumerator to calculate rectangle ocupped by the bookmark.
    // Code is simplified and handles only situation when whole bookmark is on page.
    enumerator.setCurrent(collector.getEntity(bk.getBookmarkStart()));

    // Print bounding box of the BookmarkStart
    Rectangle2D rect = enumerator.getRectangle();
    System.out.println("Page:" + enumerator.getPageIndex() + " X=" + rect.getX() + "; Y=" + rect.getY() + "; Width=" + rect.getWidth() + "; Height=" + rect.getHeight());

    // Do the same for the bookmark end.
    enumerator.setCurrent(collector.getEntity(bk.getBookmarkEnd()));
    rect = enumerator.getRectangle();
    System.out.println("Page:" + enumerator.getPageIndex() + " X=" + rect.getX() + "; Y=" + rect.getY() + "; Width=" + rect.getWidth() + "; Height=" + rect.getHeight());

    // If you need to calculate bounding box of the whole area ocuppied by bookmark,
    // you can calculate it as union of the start and end lines
    // if the bookmark start and end are located on the same page and the same txt column.
    // Otherwise it will be required to add additional logic to calculate bounding box
    // of bookmark'  located on different pages or text columns

    System.out.println("=============================");
}
