First, sorry for not responding to your other replies, there was a jam
in Thunderbird and I did not receive your answers.
The bits() seem to stay alive after deleting the image:
from PySide import QtGui
image = QtGui.QImage('/home/peter/code/pyTools/sandbox/images/faceDemo.jpg')
a = image.bits()

Btw, I just wanted to file a bug at PySide, but it might be alright at
their end, because I can do this:
from PySide import QtGui
image = QtGui.QImage('/home/peter/code/pyTools/sandbox/images/faceDemo.jpg')
a = image.bits()
del image
a

I probably did something wrong, but it does not work how I tried it. I
am not sure if you meant it like this, but I tried to subclass from
ndarray first, but then I do not have access to __array_interface__. Is
this what you had in mind?
from PySide import QtGui
import numpy as np
class myArra
Brilliant thanks, I will try out the "little class" approach.

Hi,
I as the title says, I am looking for a way to set in python the base of
an ndarray to an object.
Use case is porting qimage2ndarray to PySide where I want to do
something like:
In [1]: from PySide import QtGui
In [2]: image =
QtGui.QImage('/home/peter/code/pyTools/sandbox/images/faceDem
