title: How do I convert a numpy array to (and display) an image?
body: <p>I have created an array thusly:</p>
  
  <pre><code>import numpy as np
  data = np.zeros( (512,512,3), dtype=np.uint8)
  data[256,256] = [255,0,0]
  </code></pre>
  
  <p>What I want this to do is display a single red dot in the center of a 512x512 image. (At least to begin with... I think I can figure out the rest from there)</p>
