[Numpy-discussion] PyArray_BASE equivalent in python

[Peter Rennert]

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/faceDemo.jpg')

In [3]: import numpy as np

In [4]: a = np.frombuffer(image.bits())

--> I would like to do something like:
In [5]: a.base = image

--> to avoid situations such as:
In [6]: del image

In [7]: a
Segmentation fault (core dumped)

The current implementation of qimage2ndarray uses a C function to do

     PyArray_BASE(sipRes) = image;
     Py_INCREF(image);

But I want to avoid having to install compilers, headers etc on target 
machines of my code just for these two lines of code.

Thanks,

P
