django-tint 0.0.4

Usage

You must define your transformation in your TINT_TRANSFORMATIONS settings variable.

You set your images on your models puting a ForeignKey to tint.models.Image.

Then you put your images in your templates using the 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 image_at_transformation function. Example:

<img src="{{ image_at_transformation(mymodel.my_image_field, "my-transformation-definition") }}" />

Default ImageProc Actions

Django-tint default Image Processor comes with some actions, here you have the list:

Configuration

In Django-tint you can define your ImageProc class (normally will be a subclass of the DefaultImageProc) to add your own image transformations. You can use it configuring the TINT_IMAGE_PROCESSOR settings variable. Example:

TINT_IMAGE_PROCESSOR = 'myapp.my_image_processor_module.MyImageProcessorClass'

If the variable is not defined the 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,
      },
  ]
}
