Get picture position in Apache POI from docx-document

I read docx-document that contains text and some pictures. I can call:

List<XWPFPict开发者_如何学JAVAureData> pictures = xwpfDoument.getAllPictures()

But it returns list of all pictures in the document without theirs positions. I know about method: List<XWPFPicture> pictures = run.getEmbeddedPictures();but it return always empty list.

How I can get position of each image in the document?
