I posted this message to comp.lang.python and received a response suggesting I
sent it here ....
I'm still wrestling with Python / Tkinter / PIL. I have almost got it to work
- on a Fedora Core 1 system I can now display images in a Tkinter window. But
I also run a Fedora Core 3 system, and when I tried the same procedures I get
the following errors:-
[EMAIL PROTECTED] jpgTest]$ python pil_jpg.py
Exception in Tkinter callback
Traceback (most recent call last):
File "/usr/lib/python2.3/lib-tk/Tkinter.py", line 1345, in __call__
return self.func(*args)
File "pil_jpg.py", line 26, in do_something
a.thumbnail((200,150))
File "/usr/lib/python2.3/site-packages/PIL/Image.py", line 1422, in
thumbnail
self.load()
File "/usr/lib/python2.3/site-packages/PIL/ImageFile.py", line 180,
in load
d = Image._getdecoder(self.mode, d, a, self.decoderconfig)
File "/usr/lib/python2.3/site-packages/PIL/Image.py", line 328, in
_getdecoder
raise IOError("decoder %s not available" % decoder_name)
IOError: decoder jpeg not available
I am running Python 2.3.4, PIL 1.1.5 on a Fedora Core 3 system. I know
the code is ok, as it runs quite happily under FC1 and Windows. I've
searched around for clues, and found a few references to this error
message, but quite frankly don't understand what they are saying.
Searching around for files that look as if they may be the jpeg
libraries I can find
/usr/lib/libjpeg.so.62.0.0, and a symbolic link /usr/lib/libjpeg.so.62
I think I somehow have to configure PIL to recognise these, but I am
not sure and anyway don't know how to do this.
Can anyone help?
Peter
