title: When saving turtle graphics to an .eps file, the background color shows on the screen but is not saved in the .eps file
body: <p>I am new to Python and have been working with the turtle module as a way of learning the language.</p>
  
  <p>Thanks to stackoverflow, I researched and learned how to copy the image into an encapsulated postscript file and it works great.  There is one problem, however. The <code>turtle</code> module allows background color which shows on the screen but does not show in the <code>.eps</code> file.  All other colors, i.e. pen color and turtle color, make it through but not the background color.</p>
  
  <p>As a matter of interest, I do not believe the import of <code>Tkinter</code> is necessary since I do not believe I am using any of the <code>Tkinter</code> module here.  I included it as a part of trying to diagnose the problem.  I had also used <code>bgcolor=Orange</code> rather than the <code>s.bgcolor="orange"</code>.  </p>
  
  <p>No Joy.</p>
  
  <p>I am including a simple code example:</p>
  
  <pre><code># Python 2.7.3 on a Mac
  
  import turtle
  from Tkinter import *
  
  s=turtle.Screen()
  s.bgcolor("orange")
  
  bob = turtle.Turtle()
  bob.circle(250)
  
  ts=bob.getscreen()
  ts.getcanvas().postscript(file = "turtle.eps")
  </code></pre>
  
  <hr>
  
  <p><s>I tried to post the images of the screen and the <code>.eps</code> file but stackoverflow will not allow me to do so as a new user.  Some sort of spam prevention.  Simple enough to visualize though, screen has background color of orange and the eps file is white.</s></p>

  <p>I would appreciate any ideas.</p>
