title: Python PIL - Draw Circle
body: <p>I am trying to draw a simple circle and save this to a file using the Python Imaging Library:</p>
  
  <pre><code>import Image, ImageDraw
  
  image = Image.new('RGBA', (200, 200))
  draw = ImageDraw.Draw(image)
  draw.ellipse((20, 180, 180, 20), fill = 'blue', outline ='blue')
  draw.point((100, 100), 'red')
  image.save('test.png')
  </code></pre>
  
  <p>The point <code>draw.point</code> appears on the image, but the ellipse itself does not. I tried changing the mode to just <code>RGB</code> (I thought the mode might affect what is displayed), but this did not solve it.</p>
  
  <p>How can I fix this? Thanks!</p>
