Seems to be a problem with Photo's handling of manipulated Zope Image objects... I moved to a alternative, called VarImage 2.31, different but more powerful, escpecially for my needs. VarImage 2.31 is available at... http://www.anansispaceworks.com/ VarImage's author made note of handling this problem in 2.3, perhaps the Photo product is just getting old, and hasn't kept pace. Has some great features, axis-flipping, black & white, scaling, cropping, etc. Like I said, different, powerful, and without the error. -Jon Cyr cyrj@cyr.info Jonathan Cyr wrote:

Hello,

I am having a problem converting Image objects generated by PIL to Photo objects (rbickers' Photo & Photo Folder 1.23) in Zope 2.7.0.

The error I get is:

Error Type: AttributeError Error Value: 'str' object has no attribute 'read'

I am uploading an image into Zope, I am using an External Method & PIL to standardize the dimensions & format of the image. The method is extremely similar to the example the the Zope Book example of External Methods & PIL Thumbnail script. At this point, I'd like to take these homegenous image objects and convert them to Photo objects inside a PhotoFolder and take advantage of the render-on-the-fly sizes. I'm using RBickers' script image2photo python script, and I get the above error.

Here's the code for the thumbnails, works fine, Images seem fine, work fine, but wont convert to Photo...

...

def makeThumbnail (self, original_id, original_title, size=150): """ Makes a thumbnail image given an image ID when called on a Zope folder. Modified for WeddingWeblog from code in the Zope Book, Ch10

The thumbnail is a Zope image object that is a small JPG representation of the original image

"""

from PIL import Image from StringIO import StringIO import os.path

#create a thumbnail image file original_image=getattr(self, original_id) original_file=StringIO(str(original_image.data)) image=Image.open(original_file) image=image.convert('RGB') image.thumbnail((size,size)) thumbnail_file=StringIO() image.save(thumbnail_file, "JPEG") thumbnail_file.seek(0)

#create an ID for thumbnail path, ext=os.path.splitext(original_id) thumbnail_id=path + '_' +str(size)

# if there's an existing thumbnail delete it. if thumbnail_id in self.objectIds(): self.manage_delObjects([thumbnail_id])

# create the Zope Image Object self.manage_addProduct['OFSP'].manage_addImage(thumbnail_id, thumbnail_file, title=original_title) thumbnail_image=getattr(self, thumbnail_id)

I'm using the Image2Photo script in the Photo/PhotoFolder support, pythonscript:

...

for image in context.objectValues(['Image']): context.manage_delObjects([image.getId(),], REQUEST=context.REQUEST)

context.manage_addProduct['Photo'].manage_addPhoto(image.getId(), image.title, image.data, REQUEST=context.REQUEST)

I'm not well versed in the object types here...

any ideas?
