I would like to create a thumbnail from a jpeg file. Here is the fonction i use :
def ThumbNail(self): import Image, os, sys texte = "ok" img = Image.open("essai.jpg") img.thumbnail((50, 50)) img.save('essaiThumbnail.jpg', "JPEG") return texte
The file "essai.jpg" is in the Zope directory. It works very well from the Python command line, but it doesn't work when i use it in an external method. Zope finds the file but this error is raised :
(i'm using Zope 2.4 win32 - Python 2.1 - PIL 1.1.1) Error Type: IOError Error Value: cannot identify image file ..... File C:\Program Files\zope\Extensions\ScriptsEpinet.py, line 24, in ThumbNail File c:\python21\pil\Image.py, line 902, in open IOError: (see above) Maybe, PIL does not find its JPEG module and therefore is unable to recognize JPEG files.
