Hi all, I encountered a problem when trying to generate thumbnails from large images. My code is based on a chunk from zopelabs: def makeThumbnail(self, imagename, width, height): # get the original large image oriImage = getattr(self, imagename) # convert it to a file oriFile = cStringIO.StringIO(oriImage.data) ... etcetera It seems that oriImage.data is of <type 'string'> when a small image is passed, which is good. When a large image is used, the type of oriImage.data changes to <extension class Acquisition.ImplicitAcquirerWrapper>... Is this a memoryproblem? Or even a memorybug? What is this Acquisition.ImplicitAcquirerWrapper class? I use Zope 2.3.3 on Redhat 7.1. Appreciate any advice... TIA, Antwan.
