[Zope] Re: Generating thumbnails on the fly using PIL

[Pieter Claerhout]

Hi all,

I got quite a lot further now. Here's the script I have so far:

import PIL.Image
import os.path
import cStringIO

def MakeThumb(self, image, width, height):
    oriImage = getattr(self, image)
    oriFile = cStringIO.StringIO(oriImage.data)
    image = PIL.Image.open(oriFile)
    image.thumbnail((width, height))
    thumbnailImage = StringIO()
    image.save(thumbnailImage, "JPEG")
    thumbnailImage.seek(0)
    return thumbnailImage.getvalue()

this all works find if you use it as:

<dtml-var "PHTO_MakeThumb('AB_action_inbox.jpg', 160, 120)">

As soon as you want to do something like:

<dtml-var "PHTO_MakeThumb('/images/AB_action_inbox.jpg', 160, 120)">

you get an AttributeError. Does anybody has a way around this?

Cheers,


Pieter
