PIL question - saving JPEG

[news.west.cox.net]

I have a fairly simple Python program that uses Image and ImageDraw to
create poll results on the fly.

Because PIL only supports 256 colors for GIF and BMPs are huge (in
comparison)... I have opted to create JPEGs.

I have installed JPEG-6b and have checked to see that all of the libraries
are in the correct, expected places. But, I am still getting the following
error.

IOError: encoder jpeg not available

Anyone with some PIL experience know how to get this working? I really
appreciate any help offered.

If you need more information, just ask. I will be checking this post for
the next few days.

have you verified that PIL's build process was able to find and link against
the JPEG libraries? here's how to fix this in 1.1.4 and earlier:

http://effbot.org/zone/pil-decoder-jpeg-not-available.htm

for 1.1.5, setting the JPEG_ROOT variable in the setup.py file should do
the trick. see comments in that file for details.

Thanks for the link. However, after completing the list of changes, and
reconfiguring, remaking, rebuilding and reinstalling... still no luck.

I will try again tomorrow when I have regained a little bit of patience. If
there are any other links like this one out there I would love to give it a
shot too.

Thanks for any help.

Got it working.

I needed to copy the PIL directory intp site-packages/PIL...
apparently the pyc files do not get recreated automatically.

.pyc files are created from .py files, but if you only have .pyc files,
Python will work with them.

I would bet there weren't any .py files in site-packages/PIL.

Another option is to use the PNG format, especially since you create
graphs. PNGs have better quality and compression for this type of
images.
