title: Trying to ROTATE a simple picture in Python using skimage.transform
body: <p>I have a simple picture in Python 3.X
  I can display it.
  However, I cannot rotate it, using skimage.transform.rotate.</p>
  
  <p>The error is that my 'Picture' object has no shape. I've seen the .shape included after the rotate command, but it still does not work.</p>
  
  <p>Here is my code</p>
  
  <pre><code>import skimage
  from skimage import novice
  
  # New, all black picture
  pic = skimage.novice.Picture.from_size((600, 600), color=(0, 0, 0))
  
  # Coloring some pixels in white
  for i in range(0, len(all_dots) - 1, 2):
      x = all_dots[i]
      y = all_dots[i + 1]
      pic[x, y] = (255, 255, 255)
  
  from skimage.transform import rotate
  
  new_pic = rotate(pic, 180)
  # Also new_pic = rotate(pic, 180).shape does not work
  
  new_pic.show()
  </code></pre>
  
  <p>Any ideas? Thanks</p>
