Rotation with scpecification of the center ?

Hi everyone, this is my first post here, so I am really a newbie... I haev seen on the doc that it is possible to specify the center of rotation (http://scikit-image.org/docs/dev/api/skimage.transform.html#skimage.transfor...) with rotate(image2,90 , resize=False, order=1, mode='constant', cval=0.0, center=(1140,1383)) but my computer doesn't seem very happy with this parameter center : rotate() got an unexpected keyword argument 'center' how can I specify the center of rotation ? thanks a lot, Julien
