Populate METAFILEPICT struct given a HMETAFILE. Missing something simple?

Pretty simple problem it seems.

Code:

---

                        HMETAFILE hMetaFile = GetMetaFile(myMetaFile);

                        METAFILEPICT myMetaPict;

                        // ??? What can I do to populate the METAFILEPICT struct to access variables below.

                        myMetaPict.yExt;
                        myMetaPict.xExt;
