[Zope] Generating thumbnails on the fly using PIL

[Tom Cameron]

I am pretty sure you dont _need_ to use a python script. The example simply
uses that as a nice way to call the external method. You can just as easilly
call the method from DTML.

=> I had a look at this yesterday, but apparently, you need both an external
=> method and a Python script, and I prefer to have only an external method.

=> have you read the example on this page
=> http://www.zope.org/Members/michel/ZB/ScriptingZope.html
=> it does not create the thumbnails on the fly, but it does show you how to
=> get the data into stringIO

=> => Hi all,
=> =>
=> => I'm trying to make an external method that creates a thumbnail
=> => of an image
=> => on the fly. I want to give it the url of the image and return
=> the image
=> => data. It should look something like:
=> =>
=> => <dtml-var "MakeThumb('/path/to/my/image.jpg', (64, 32))">
=> =>
=> => I figured out already that I should use a StringIO object to
=> => store the raw
=> => image data in, so that PIL has an object to work with. The only
=> => two things
=> => I'm struggling with still are:
=> =>
=> => - How do you get the data of the image in the StringIO object?
=> => - How do you return the thumbnail image?
=> =>
=> => Hope that somebody can help with this.
=> =>
=> => Cheers,
=> =>

=> => Pieter
