Hello there,

I have been trying for a while to use both Local File system objects and external methods.

I need to get the file path of my LocalFS image. But it seems I cannot apply ._local_path to these kind of objects.

File C:\TestRes\lib\python\DocumentTemplate\VSEval.py, line 175, in __init__

(Object: Imagenes['logo.gif']._local_path)

TypeError: illegal name used in expression

Meanwhile I tried to explicitly pass the file location to my external method

Where my external method is:

#minipil.py

import Image

def conversion(a):

im = Image.open(a)

return im.format

Error Type: IOError

Error Value: [Errno 22] Invalid argument: "c:\\TestRes\\images\\logo.gif/"

Traceback (innermost last):

File C:\TestRes\lib\python\App\ImageFile.py, line 110, in __init__

IOError: (see above)

The idea is to use PIL to convert images from bmp to gif. This is working fine, the Image module is finally working in Zope. But I cannot go on until I find out the way to access those images through the external method. That is why now the only thing I do with my method is to return the image format. To keep things simple...and try to find out what is failing.

Anyway...can someone help me with this, please?

Thanks a lot.
