Thank you I tried that and I still get the same error.
I spent a little more time looking at PIL / Image.py and cleaning up
the code. From what I can tell the Image.open method is having trouble
with what I am passing to it.
def resize_image(file, size=(50, 50)):
from PIL import Image
from cStringIO import StringIO
from django.core.files.base import ContentFile
image_data = StringIO(file.read())
### this line below is where the issue is ###
image = Image.open(image_data)
if image.mode not in ('L', 'RGB'):
image = image.convert('RGB')
image.thumbnail(size, Image.ANTIALIAS)
o = StringIO()
image.save(o, "JPEG")
return ContentFile(o.getvalue())
This is how I call it:
picture = pform.cleaned_data['picture']
thumbnail_content = resize_image(picture)
Thank you for looking at this.
