Moin moin! (Enthought Canopy Python 2.7.3 | 64-bit | (default, Aug 8 2013, 05:30:12) [MSC v.1500 64 bit (AMD64)] on win32) I noticed that the rotate function is not working correct for me or at least not in the way I expect it to function. Could someone check this or tell me what I'm doing wrong. I would like to rotate a image/array for some degrees. import numpy as np import matplotlib.pyplot as plt import skimage.transform as sk_trans im_array = np.ones((30,30)) im_array[12,:]=2 im_array[13,:]=3 im_array[14,:]=4 im_array[15,:]=5 im_array[16,:]=4 im_array[17,:]=3 im_array[18,:]=2 img_rot = sk_trans.rotate(im_array,45) plt.imshow(im_array,interpolation='none') plt.show() plt.imshow(img_rot,interpolation='none') plt.show() Thanks Siggi
