[Image-SIG] PIL and Tk PhotoImage

[mark brady]

The following simple program is supposed to read an image
using PIL and then convert it into a Tkinter PhotoImage (Running
on a Mac):

   from Image import *
   from Tkinter import *

   im = open("lena.jpg")
   im.load()
   tkIm = PhotoImage(im)

Instead, it chokes on the last line, giving the following error message:

   Traceback (most recent call last):
       File "Macintosh HD:Applications:Python 2.0:MyToys:MakeTkImage", line
6, in ?
           tkIm = PhotoImage(im)
       File "macintosh hd:applications:python 2.0:lib:lib-tk:Tkinter.py",
line 2974, in __init__
           apply(Image.__init__, (self, 'photo', name, cnf, master), kw)
       File "macintosh hd:applications:python 2.0:lib:lib-tk:Tkinter.py",
line 2915, in __init__
           raise RuntimeError, 'Too early to create image'
       RuntimeError: Too early to create image

Why is it too early to create the image?
