I have a set of tif images that generated for a dicom images using ImageMagic
convert utility. The Image module does not identify them (even identify utility
seems to be inconsistent about them, as shown below):
Try to read image via Image module
===================================
In [2]: import Image
In [3]: Image.VERSION
Out[3]: '1.1.6'
In [6]: im = Image.open('disk1_00_00_00_ct000104.tif')
---------------------------------------------------------------------------

-> 1916 raise IOError("cannot identify image file")
