It is not even in the source repository.
I venture a guess that the "pilimages.py" is an extra file provided by the
instructor of your class

I would try this first:

sudo apt-get install python-imaging

before trying to compile my own version

I have used http://www.haynold.com/software_projects/2004/pytiff/ before.
The project seems to abandoned but it worked very nicely for my simple needs.

Another option worth considering is to use something like:
 http://www.libtiff.org/ in combination with subprocess module.

Re: [Image-SIG] seeking guidance on image conversion

pytiff library should be able to do it
(http://www.haynold.com/software_projects/2004/pytiff/)
I have used it on small scale for the same purpose.

pytiff again.

Alternatively one could use Ghostscript for the purpose.  They provide
even a shared library that could be driven using ctypes.

If windows machine has PDFCreator installed
(http://www.pdfforge.org/products/pdfcreator) one could use Python COM
to drive Word and print directly into PDF format.

Use prepackaged version of PIL if you can.
apt-get is your friend
Or for command line challenged, Synaptic.

[Image-SIG] help(aggdraw.Draw instance) -> crash on Windows?

[Waldemar Osuch]

I have observed following on Windows XP:

Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from PIL import Image
>>> Image.VERSION
'1.1.5'
>>> import aggdraw
>>> aggdraw.__version__
'1.2a2'
>>> image = Image.new('RGB', (600, 430), 'white')
>>> draw = aggdraw.Draw(image)
>>> help(draw)
-->PYTHON CRASH<--

Can anyone else confirm it?
My machine started to act funny recently so maybe it is time to rebuild it.
