Hi,
I am looking for some function that would shear my 2D numpy.ndarray array. Since
the numpy (probably) does not provide such a functionality (numpy.roll does not
do what I need), I hope the PIL might do the trick.
Google give me page that says: 'This function (im.transform) can be used to
scale, translate, rotate, and shear the original image.', however I was not able
to get it work.
So could anybody give me a hand how to use it (or how to shear the image in
different way)?
You should be able to use scipy.ndimage.affine_transform() to do the job:

If you cannot get it to work, please show us what you tried, the results you
got, and what you expected to get. You can find the scipy mailing lists here:
