I have a program for image treatment. The program itself works fine, but when I change the desktop or laptop (all on windows 7) I'm using it in, it sometimes says randomly:
Traceback (most recent call last):
File "P:\ISN\Projets\Traitement image\Test 2.py", line 152, in <module>
im1 = Tkinter.PhotoImage(file=a)
File "C:\Program Files\EduPython\App\lib\tkinter\__init__.py", line 3287, in __init__
Image.__init__(self, 'photo', name, cnf, master, **kw)
File "C:\Program Files\EduPython\App\lib\tkinter\__init__.py", line 3243, in __init__
self.tk.call(('image', 'create', imgtype, name,) + options)
_tkinter.TclError: couldn't recognize data in image file "P:/ISN/Projets/Traitement image/Images/obama.png"
As you can see, the image format is .png. I'm using PIL, so png images are supposed to be supported, and my image files are not corrupted. I use them all the time, and they work fine. But this randomly happens, and I'm afraid the day I'll have to present my program, it would crash on me. Here's my code:
