django-multimedia

django-multimedia is a super simple, reusable Django 1.0 application for managing media
files. Currently, it supports image files (JPEG, PNG, TIFF, and GIF); audio and
video files are planned. It doesn't do much, but I find it useful for managing images
on a blog.

Quick introduction
==================

Django-multimedia adds a "Media" model to your website. Using the Django admin
interface, you can upload an image, write a caption for it, specify attribution,
etc.

To insert a thumbnail image from one of your templates:

  {% load multimedia_tags %}
  {% thumbnail 15 with format=600x400,round=10 %}
  
If you use a Media object as a foreign key in your own models, you can refer
to the media object directly, instead of using its id:
  
  {% thumbnail entry.picture format=600x400,round=10 %}
  
This renders the Media object with id=15 (or entry.picture) as a 600x400 pixel
thumbnail image with rounded corners of radius 10 using a default template (see
below). If the thumbnail doesn't exist, it is automatically generated and stored
in the same directory as the media file.

The 'format' setting is shorthand for the look of a thumbnail image. Currently,
the following options are supported:

  [width]x[height]          thumbnail width and height
  square or !square         crop image to a square or not
  round=[n]                 round corners, where n is the radius in pixels
  bg=[color]                background color for the empty space that's created
                            when an image is rounded (e.g., 'ff0000')
  template=[template]       Django template used to render the image
  [:named_format]           refer to a format defined in settings.py

A format can be specified inline, as in the example above, or defined in 
settings.py and referenced using its name. This is useful when you want a
consistent format across several templates. For example:

  ...in your settings.py:
  
  MULTIMEDIA_FORMATS = [
    'mini': '200x200,square,round=5,bg=ffffff'
    'blog': '600x400,round=10,bg=ffffff,template=blog/blog_image.html',
  ]
  
  ...in your templates:
  
  {% thumbnail 42 format=:mini %}
  {% thumbnail entry.picture format=:blog %}

By default, a Django template provided with django-multimedia is used to render
the thumbnail. It renders the image with a <div> wrapper that contains the <img>
as well as a sub-<div>s for the caption and attribution. This template is defined
in "multimedia/tempaltes/render-media-default.html". To use your own templates, 
specify it in the "template=" format setting.

Instead of rendering the thumbnail, you can have it assigned to a context variable.
For example:

  {% thumbnail 42 format=:mini as minithumb %}
  
  ...and then refer to it like so:
  
  <div style="float:left; width:{{minithumb.width}}px; height:{{minithumb.height}}px;">
    ...
    <p>Caption: {{minithumb.media.caption}}</p>
    ...
  </div>
  
The context variable "minithumb" has the following attributes:

  media          the Media object for this thumbnail
  format         the format setting (as a dictionary)
  url            the url to the thumbnail image
  width          the width of the thumbnail image
  height         the height of the thumbnail image
