This release is a pre-release and may not be stable for production use.
The powerful, yet easy to implement thumbnailing application for Django.
To install this application into your project, just add it to your INSTALLED_APPS setting (and run manage.py syncdb):
INSTALLED_APPS = (
...
'easy_thumbnails',
)
Template usage
To generate thumbnails in your template, use the {% thumbnail %} tag. To make this tag available for use in your template, use:
{% load thumbnails %}
Basic tag Syntax:
{% thumbnail [source] [size] [options] %}
source must be a File object, usually an Image/FileField of a model instance.
size can either be:
the size in the format [width]x[height] (for example, {% thumbnail person.photo 100x50 %}) or
a variable containing a valid size (i.e. either a string in the [width]x[height] format or a tuple containing two integers): {% thumbnail person.photo size_var %}.
options are a space separated list of options which are used when processing the image to a thumbnail such as sharpen, crop and quality=90.
Model usage
You can use the ThumbnailerField or ThumbnailerImageField fields (based on FileField and ImageField, respectively) for easier access to retrieve (or generate) thumbnail images.
By passing a resize_source argument to the ThumbnailerImageField, you can resize the source image before it is saved:
class Profile(models.Model):
user = models.ForeignKey('auth.User')
avatar = ThumbnailerImageField(
upload_to='avatars',
resize_source=dict(size=(50, 50), crop='smart'),
)
Lower level usage
Thumbnails are generated with a Thumbnailer instance. For example:
from easy_thumbnails import Thumbnailer
def square_thumbnail(source):
thumbnail_options = dict(size=(100, 100), crop=True, bw=True)
return Thumbnailer(source).get_thumbnail(thumbnail_options)
By default, get_thumbnail saves the file (using file storage). The source file used to instanciate the Thumbnailer must have a name instance relative to the storage root.
The ThumbnailFile object provided makes this easy:
from easy_thumbnails import ThumbnailFile
# For an existing file in storage:
source = ThumbnailFile('animals/aarvark.jpg')
square_thumbnail(source)
# For a new file:
picture = open('/home/zookeeper/pictures/my_anteater.jpg')
source = ThumbnailFile('animals/anteater.jpg', file=picture)
square_thumbnail(source)
