Description: Django image renderer
        =====================
        
        |Build Status| |Coverage| |PyPI Version|
        
        Django image renderer is an app that will help you render images in many
        sizes (renditions). This can be really helpful for generating images
        size for different screens resolution (especially when targeting
        mobile).
        
        --------------
        
        Features
        --------
        
        -  uses `Pillow <https://github.com/python-pillow/Pillow>`__ to resize
           images
        -  uses Django's *default\_storage* to let you play with whatever
           storage backend you'll need
        -  uploaded image files named using uuid
        -  rendition cached on disk
        -  resize keeping original aspect ratio
        -  crop if needed
        -  simple widget for admin site
        
        Quick start
        -----------
        
        Install the app.
        
        .. code:: sh
        
            pip install django-image-renderer
        
        Add "renderer" to your INSTALLED\_APPS setting like this:
        
        *settings.py*
        
        .. code:: python
        
            INSTALLED_APPS = (
                # your apps
                'renderer',
            )
        
        Include the renderer URL configuration in your project *urls.py* like
        this:
        
        *urls.py*
        
        .. code:: python
        
            url(r'^renderer/', include('renderer.urls', namespace='renderer')),
        
        Run ``python manage.py migrate`` to create the renderer models.
        
        Start the development server and visit http://localhost:8000/admin/ to
        create a MasterImage (you'll need the Admin app enabled).
        
        Requirements
        ------------
        
        -  Python (2.7, 3.4, 3.5)
        -  Django (1.7, 1.8, 1.9)
        
        Usage
        -----
        
        There is only one model in the app: *MasterImage*. With a *MasterImage*
        you can ask for renditions.
        
        .. code:: python
        
            m = MasterImage.objects.first()
        
            # get the master file's URL
            m.get_master_url()
            # or
            m.get_rendition_url(0, 0)
        
            # cache and return URL of a renditions that as 200 pixels width
            # and height computed according to master's aspect ratio
            url = m.get_rendition_url(200, 0)
        
            # cache and return URL of a renditions that as 50 pixels height
            # and width computed according to master's aspect ratio
            url = m.get_rendition_url(0, 50)
        
        If you ask for a size that do not fit master's aspect ration you'll
        receive a center cropped image.
        
        You can also ask for a rendition in templates.
        
        *models.py*
        
        .. code:: python
        
            def index(request):
                m = MasterImage.objects.first()
                return render(request, 'demo/index.html', {
                    'master': m,
                })
        
        *index.html*
        
        .. code:: html+django
        
            {% load renderer %}
            ...
            {% rendition master 42 42 %}
            ...
            {% rendition_url 42 42 %}
            ...
        
        This will render as:
        
        .. code:: html
        
            <img src="/media/img/0fb34de8-9d83-456a-828b-72ab21f8ebab_42x42.png" width="42" height="42" alt="">
            ...
            /media/img/0fb34de8-9d83-456a-828b-72ab21f8ebab_42x42.png
            ...
        
        When using *MasterImage* in your model you may need a widget who
        provides a preview for you image. For convenience a mixin is provided.
        
        *models.py*
        
        .. code:: python
        
            from django.db import models
        
            class DemoModel(models.Model):
                master = models.ForeignKey('renderer.MasterImage')
        
        *admin.py*
        
        .. code:: python
        
            from demo.models import DemoModel
            from django.contrib import admin
            from renderer.widgets import MasterImageAdminMixin
        
            @admin.register(DemoModel)
            class DemoModelAdmin(MasterImageAdminMixin, admin.ModelAdmin):
                fields = ('master', )
        
        Sample project
        --------------
        
        A sample project is available in the
        `sample <https://github.com/rouk1/django-image-renderer/tree/master/sample>`__
        folder. Test it as an usual Django project:
        
        .. code:: sh
        
            virtualenv --no-site-packages venv
            source venv/bin/activate
            pip install -r requirements.txt
            python sample/manage.py migrate
            python sample/manage.py createsuperuser
            python sample/manage.py runserver
        
        It' also deployed at http://django-image-renderer.herokuapp.com/.
