easy-thumbnails Description

Easy thumbnails for Django easy-thumbnails is a 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 usageTo 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 must be a File object, usually an Image/FileField of a model instance.size can either be: * the size in the format x (for example, {% thumbnail person.photo 100x50 %}) or * a variable containing a valid size (i.e. either a string in the x 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 usageYou 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 usageThumbnails are generated with a Thumbnailer instance. For example:from easy_thumbnails import Thumbnailerdef 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) Requirements: · Python · Django
