Project Description

This CKAN extension adds support for generation and display of thumbnail images. The helper function thumbnail_url can be called from a template, as in this example:

{% block thumbnail %}
{% set thumbnail = h.thumbnail_url(package.id) %}
{% if  thumbnail %}
    <a href="{{ h.url_for(controller='package', action='read', id=package.name) }}">
    <img class="dataset-list-thumbnail" src="{{ thumbnail }}">
    </a>
{% endif %}
{% endblock %}
  • If a resource exists with the name thumbnail.png, this will be used.
  • If no resource exists with this name and the logged-in user has sufficient access, the thumbnail will be generated from the first matching JPEG or PNG resource.
  • If no thumbnail exists at this point, a placeholder image will be used.

Requirements

  • CKAN 2.5.2
  • Pillow 3.2.0 (with PngImagePlugin and JpegImagePlugin)
