Hello,
I have a custum content type "SightFolder" with a field "img" of
"image" type. I would like to use some PIL transformations on the
image saved in the image field, so I have added a method into the
content type class. But all my attempts fail.
I import PIL as:
from PIL import Image
A field is defined as:
ImageField(
name='img',
widget=ImageField._properties['widget'](
label="Map",
),
searchable=0,
required=0,
storage=AnnotationStorage(),
),
A method in the class is defined as:
security.declarePublic('Rotate')
def Rotate(self, img):
out = img.rotate(45)
return out
And I try to call it from a template as:
<span tal:replace="structure
python:context.Rotate(context.img).tag()"></span>
But i generates the following error:
Module Products.PageTemplates.ZRPythonExpr, line 49, in __call__
- __traceback_info__: context.Rotate(context.img).tag()
Module PythonExpr, line 1, in <expression>
Module Products.Sightseeing.SightFolder, line 142, in Rotate
AttributeError: rotate
Do you have any idea what is wrong? Is there any better way how to
input an image from a field into a method?
Thanks a lot for any help in advance.
Jan
