Get the image (picture) of an django database using django-image-cropping and easy-thumbnails

Question

I have an django installation with the plugins django-image-cropping and easy-thumbnails in use.

I want to add users pictures to there vCard using vObject.

models.py:
(...)
class Person(TranslatableModel):
    (...)
    pic = ImageCropField(_(u"profile picture"),
        blank=True,
        null=True,
        upload_to=settings.USER_PICTURE_DIR,
    )
    picture_cropped = ImageRatioField(
        'pic',
        '{}x{}'.format(*settings.USER_PICTURE_SIZE)
    )
(...)

So far all I can find about this topic is, how to get an URL to the original Picture, but I don't know how to get the cropped Picture nor do I know how to get the Picture itself and not an URL nor a pseudo-file-type.

You are using an older version of django-image-cropping as the ImageCropField does no longer exist in recent versions.

For the latest version it is documented how to get the URL for a cropped thumbnail from your python code: https://github.com/jonasundderwolf/django-image-cropping#frontend

from image_cropping.utils import get_backend
thumbnail_url = get_backend().get_thumbnail_url(
    yourmodel.image,
    {
        'size': (430, 360),
        'box': yourmodel.cropping,
        'crop': True,
        'detail': True,
    }
)

In older versions you would use:

from easy_thumbnails.files import get_thumbnailer
thumbnail_url = get_thumbnailer(yourmodel.image).get_thumbnail({
    'size': (430, 360),
    'box': yourmodel.cropping,
    'crop': True,
    'detail': True,
}).url
