About a year+ ago I quit programming, currently my interest
has been stimulated again and I am trying to get back up
to speed.
I started out futzing around with pyscopg 2.0.4. and tried
to get it to build...
I quickly realized that I was in bad shape ( memory wise...).
I decided to upgrade to 2.4.1 and got the upgrade and the Tiger Python
Fix and started again...
I finally got the python interfaces for Postgresql and Sqlite build
and convinced myself that things were getting better.
I used the package manager to download PIL and things fell apart again
I don't seem to be able to display any sort of image.
Here is a little program that I sorta recollect that worked.
from Tkinter import *
import Image,ImageTk
import sys
def main():
filename = sys.argv[1]
root = Tk()
img = ImageTk.PhotoImage(file=filename)
label = Label(root, image=img)
label.pack()
root.mainloop()
main()
Running the above with any kind of graphics file
gives a dump like:
Traceback (most recent call last):
File "imageview.py", line 13, in ?
main()
File "imageview.py", line 8, in main
img = ImageTk.PhotoImage(file=filename)
File "/Users/jerry/Library/Python/2.4/site-packages/PIL/
ImageTk.py", line 85, in __init__
image = Image.open(kw["file"])
File "/Users/jerry/Library/Python/2.4/site-packages/PIL/Image.py",
line 1745, in open
raise IOError("cannot identify image file")
IOError: cannot identify image file
Exception exceptions.AttributeError: "PhotoImage instance has no
attribute '_PhotoImage__photo'" in <bound method PhotoImage.__del__
of <ImageTk.PhotoImage instance at 0x23edf0>> ignored
If I drop the ImageTk prefix to the PhotoImage line I can view Gifs.
Several other programs that I am fairly sure worked also fail with the
"cannot identify image file" error.
Tkinter seems to be more or less working, I have a visual Postgresql
browser that is
built out of a number of tk widgets.
Tk itself seems to be working fine. I have written a photo browser
that can view a large
number of image formats and it appears to be working fine.
I installed PIL using the Package Manager and it installed into
~/Library/Python/2.4/site-packages.
Can anyone offer any clues as to what my problem is?
Jerry
