Tests
-----
The tests should run with tox and pytest. Running `tox` will run all tests for all environments.
However, it is possible to run a certain environment with `tox -e <env>`, a list of all environments
can be found with `tox -l`. These tests require the dependencies of the different engines defined in
the documentation. It is possible to install these dependencies into a vagrant image with the
Vagrantfile in the repo.

How to Use
==========

Get the code
------------

Getting the code for the latest stable release use 'pip'. ::

   $ pip install sorl-thumbnail

Install in your project
-----------------------

Then register 'sorl.thumbnail', in the 'INSTALLED_APPS' section of
your project's settings. ::

    INSTALLED_APPS = (
        'django.contrib.auth',
        'django.contrib.admin',
        'django.contrib.sites',
        'django.contrib.comments',
        'django.contrib.sessions',
        'django.contrib.messages',
        'django.contrib.contenttypes',

        'sorl.thumbnail',
    )


Templates Usage
---------------

All of the examples assume that you first load the thumbnail template tag in
your template.::

    {% load thumbnail %}


A simple usage. ::

    {% thumbnail item.image "100x100" crop="center" as im %}
        <img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}">
    {% endthumbnail %}

See more examples in the section `Template examples`_ in the Documentation

Model Usage
-----------

Using the ImageField that automatically deletes references to itself in the key
value store and its thumbnail references and the thumbnail files when deleted.::

    from django.db import models
    from sorl.thumbnail import ImageField

    class Item(models.Model):
        image = ImageField(upload_to='whatever')

See more examples in the section `Model examples`_ in the Documentation

Low level API
-------------

You can use the 'get_thumbnail'::

    from sorl.thumbnail import get_thumbnail
    from sorl.thumbnail import delete

    im = get_thumbnail(my_file, '100x100', crop='center', quality=99)
    delete(my_file)

See more examples in the section `Low level API examples`_ in the Documentation

Using in combination with other thumbnalers
-------------------------------------------

Alternatively, you load the templatetags by {% load sorl_thumbnail %}
instead of traditional {% load thumbnail %}. It's especially useful in
projects that do make use of multiple thumbnailer libraries that use the
same name (``thumbnail``) for the templatetag module::

    {% load sorl_thumbnail %}
    {% thumbnail item.image "100x100" crop="center" as im %}
        <img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}">
    {% endthumbnail %}

Frequently asked questions
==========================

Is so slow in Amazon S3 !
-------------------------

Possible related to the implementation of your Amazon S3 Backend, see the `issue #351`_
due the storage backend reviews if there is an existing thumbnail when tries to
generate the thumbnail that makes an extensive use of the S3 API

A fast workaround if you are not willing to tweak your storage backend is to set::

   THUMBNAIL_FORCE_OVERWRITE = True

So it will avoid to overly query the S3 API.
