Looks like someone else is having a problem as well from the other day with
this module. Here's my problem, when trying to posterize an image with ImageOps
I get the output error below when executing from my script. When I'm in the
python shell and interactively executing each command the posterize process
seems to work, no errors are generated.
Python 2.5.1
SunOS 5.10
Here's the output when executing from the script. A copy of the script is
provided next, then output of me typing in the commands manually.
