[triangle-zpug] can't find font problem

[David Handy]

The Python path is only used for finding Python modules and packages, and
then only by the "import" statement. For opening regular files, you have to
specify a full pathname or a path relative to the current directory.

In this case, it looks you are trying to load the font file out of the PIL
package directory. You can find the directory of a Python package like this:

>>> import PIL
>>> PIL.__file__
'/usr/lib/python2.4/site-packages/PIL/__init__.pyc'
>>> import os
>>> os.path.dirname(PIL.__file__)
'/usr/lib/python2.4/site-packages/PIL'

So I suppose you could do something like this in your code:

label_font=ImageFont.load(os.path.dirname(PIL.__file__) + "/courR18.pil")

By the way, I just now looked in the PIL directory on my computer and didn't
see any .pil files there; I assume you put courR18.pil in that directory
yourself?

Hope this helps -
