Would you do me a favour and see whether the patch from the Image-SIG
mailing list fixes your problem as well? If not, please mail me an
example 16-bit greyscale tiff off-list, so that I can rework the
patch.
Thanks

Apparently it does not work with 16bit greyscale tif images either.
For anyone else stumbling upon this thread, there is a work-about to get the
data into a numpy array.
i = Image.open('16bitGreyscaleImage.tif')
a = numpy.array(i.getdata())# a 1d numpy array
a = a.reshape(i.size) #2d numpy array
Perhaps there is a better way of doing it (?), but this works for me.

Re: [Numpy-discussion] Applying PIL patch
Thank you for the reply. I in fact did not have the latest PIL binary. It works beautifully now. Luckily I won't be needing RGBA support soon.

[Numpy-discussion] Applying PIL patch
Hi all, Sorry for the beginner question. I want to apply the PIL-numpy patch from http://www.scipy.org/Cookbook/PIL?highlight=%28PIL%29 . I have the latest windows binaries of numpy, scipy and PIL installed. I searched python.org, but couldn't find info on applying patches. How do I apply the patch? Detailed instructions on the cookbook page would be appreciated... perhaps I should modify it to include any lucid responses to this email?
