title: Pixel Manipulation via GUI in Python (poss PIL, Tkinter)
body: <p>Here's the issue - </p>
  
  <p>I'm writing a program that will iterate through a series of image manipulations - both effecting the whole image as well as just portions of the image.  I need to demonstrate these changes to the user (myself) so I can see what's going wrong with my manipulations as they take place.  </p>
  
  <p>I originally tried to use PIL and Tkinter to do this - but I couldn't even load an image into the GUI - here's a bit of code formed from the corners of the web, via many google searches:</p>
  
  <pre><code>from Tkinter import *
  import Image, ImageDraw, ImageTk
  import time
  
  class Test(Frame):
      def __init__(self):
          Frame.__init__(self)
          self.c = Canvas(self, width=574, height=431, bg="red")
          self.c.pack()
          Button(self, text="Process", command=self.procImg).pack()
          Button(self, text="Quit", command=self.quit).pack()
      def procImg(self):
          t = time.time()
          self.flashImg = Image.open("./in_img/resize.bmp")
          #self.flashImg = flashImg.resize((574, 431))
          self.flashImg = self.flashImg.convert("L")
          #self.photo = ImageTk.BitmapImage(flashImg)
          self.c.photo = ImageTk.PhotoImage(self.flashImg)
          self.c.create_image(574, 431, anchor=NW, image=self.c.photo)
          self.c.create_rectangle(50, 50, 100, 100, fill="blue")
          self.update()
          print time.time()-t
  
  t = Test()
  t.pack()
  t.mainloop()
  </code></pre>
  
  <p>So the above code is pretty bad, I know - but I wanted to post something to prove that I have at least been working at this.</p>
  
  <p>Can anyone suggest to me a new way of approaching this problem using Python?  I'd rather not learn a different language - I'm new to the Tkinter library so if something else is better suited for this, I have no issues learning a new library. </p>
  
  <p>Also, FYI, the "resize.bmp" image is a resized .JPG from a digital camera.  I tried that one too and it didn't work - I really need to find a way to flash bitmaps from memory to the screen in a GUI so I can adjust parameters as the processing is going on.</p>
  
  <p>Thanks for your help!</p>
