title: Trying to render a barcode image, but object is not callable?
body: <p>I am trying to set up a code which creates tickets by generating images of barcodes, from a txt file, and pasting that on the ticket image.</p>
  
  <pre><code>import barcode
  import time
  from barcode.writer import ImageWriter
  mylist = []
  with open('/Users/Droid/Desktop/my_project/Tickets/Tnumfile.TXT', 'r') as f:
  for line in f.readlines():    #Walks through each line
      code = barcode.get('code', line, writer=ImageWriter()) 
      filename = code.save(line.strip())        #Saves Line 'tnumfile' as filename
      mylist.insert(0,line.strip() + '.png')
  
  
  
  time.sleep(2)
  from PIL import Image
  
  for item in mylist:
  
  im1 = Image.open('/Users/Droid/Desktop/my_project/Ticket.png') 
  im2 = Image.open('/Users/Droid/Desktop/my_project/Tickets' + item) 
  area = (30, 1380, 553, 1660)                                       
  
  im1.paste(im2, area)
  im1.save('line' + item)
  </code></pre>
  
  <p>supposed to run through .txt file converting all the barcodes to images and copying them onto the ticket image template, instead keeps telling me:</p>
  
  <pre><code>  File "C:\Users\Droid\Desktop\my_project\Script.py", line 7, in &lt;module&gt;
      code = barcode.get('code', line, writer=ImageWriter())  
  TypeError: 'NoneType' object is not callable
  </code></pre>
