Usage
~~~~~
You must define your transformation in your :code:`TINT_TRANSFORMATIONS` settings
variable.
You set your images on your models puting a :code:`ForeignKey` to
:code:`tint.models.Image`.
Then you put your images in your templates using the :code:`at_transformation` filter. Example::
{% load tint %}
<img src="{{ mymodel.my_image_field|at_transformation:"my-transformation-definition" }}" />
If you use django-jinja you only have to use the :code:`image_at_transformation` function. Example::
<img src="{{ image_at_transformation(mymodel.my_image_field, "my-transformation-definition") }}" />

Configuration
~~~~~~~~~~~~~
In Django-tint you can define your :code:`ImageProc` class (normally will be a subclass
of the :code:`DefaultImageProc`) to add your own image transformations. You can use it
configuring the :code:`TINT_IMAGE_PROCESSOR` settings variable. Example::
TINT_IMAGE_PROCESSOR = 'myapp.my_image_processor_module.MyImageProcessorClass'
If the variable is not defined the :code:`DefaultImageProc` is used.
Then you can configure your transformations as a dictionary. The name of the
transformation is the key, and the value is a list of "actions". An action is a
dictionary with one key 'action' with the name of the action, and the other
keys the parameters to use in this action. Example::
TINT_TRANSFORMATIONS = {
'example1': [
{
"action": 'fit',
"width": 1024,
"height": 768,
"align": 'center',
"valign": 'middle',
},
{
"action": 'watermark',
"image": 'example.watermark.png',
"opacity": 0.5,
},
],
'example2': [
{
"action": 'fit',
"width": 800,
"height": 600,
"align": 'center',
"valign": 'middle',
},
{
"action": 'watermark',
"image": 'example.watermark.png',
"opacity": 0.5,
},
]
}
You can define the the removing of deleted images or thumnails model instances,
remove the image file with the settings ``TINT_KEEP_THUMBNAILS`` and
``TINT_KEEP_IMAGES``, the default value is True to both settings.
You can define your file output format and your file output extension with the
settings ``TINT_IMAGE_OUTPUT_FORMAT`` and ``TINT_IMAGE_OUTPUT_EXTENSION``. The
default value is None this means use the same format and extension of the
origin file. Example::
TINT_IMAGE_OUTPUT_FORMAT = "png"
TINT_IMAGE_OUTPUT_EXTENSION = ".png"
