Using numdisplay

Numdisplay is one of the cool python astronomy packages that lack documentation! What I want to do is display an image from the python shell (easy and well documented) and this image shall contain WCS information, because otherwise I could as well use matplotlib (really hard and NOT documented).
What I know so far:
  1. open ds9 with the following command: 
    ds9 -unix "/tmp/.IMT3"
  2. in the python shell create an UnixImageDisplay 
    uid = numdisplay.displaydev.UnixImageDisplay("/tmp/.IMT3")
  3. don't really know how to continue ... the wcs stuff seems not to work the way I expect ...
Next try, this time with python-sao: 
import pysao
ds9 = pysao.ds9()
ds9.view(hdul[6])
Much better :-)
