Saving a Metafile into a RTF file

Hi there,

I have a valid TMetafile, which when I save it to a file using
metafile.SaveToFile(), the metafile is ok.
I want to put this metafile into a RTF document, but when I use
metafile.SaveToStream(), the metafile is
saved in binary format.
Does anyone know how to stream the metafile into a RTF document, preferable
in text format, and not
binary, so that Wordpad can display the image.
