djangocms-picture 4.0.0

Installation

For a manual install:

• run pip install djangocms-picture

• add djangocms_picture to your INSTALLED_APPS

• run python manage.py migrate djangocms_picture

Configuration

Note that the provided templates are very minimal by design. You are encouraged to adapt and override them to your project’s requirements.

This addon provides a default template for all instances. You can provide additional template choices by adding a DJANGOCMS_PICTURE_TEMPLATES setting:

DJANGOCMS_PICTURE_TEMPLATES = [
    ('background', _('Background image')),
]

You’ll need to create the background folder inside templates/djangocms_picture/ otherwise you will get a template does not exist error. You can do this by copying the default folder inside that directory and renaming it to background.

Another setting is DJANGOCMS_PICTURE_NESTING, which allows you to render an image as the background image of a container that also contains other content (text, icons and so on).

DJANGOCMS_PICTURE_NESTING = True

will enable this (the default is False). When set to True, you’ll be able to place additional plugins inside the picture plugin.

You can override alignment styles with DJANGOCMS_PICTURE_ALIGN, for example:

DJANGOCMS_PICTURE_ALIGN = [
    ('top', _('Top Aligned')),
]

This will generate a class prefixed with align-. The example above would produce a class="align-top". Adding a class key to the image attributes automatically merges the alignment with the attribute class.

You can enable responsive images technique by setting``DJANGOCMS_PICTURE_RESPONSIVE_IMAGES`` to True. In this case uploaded images will create thumbnails of different sizes according to DJANGOCMS_PICTURE_RESPONSIVE_IMAGES_VIEWPORT_BREAKPOINTS (which defaults to [576, 768, 992]) and browser will be responsible for choosing the best image to display (based upon the screen viewport).

You can use DJANGOCMS_PICTURE_RATIO to set the width/height ratio of images if these values are not set explicitly on the image:

DJANGOCMS_PICTURE_RATIO = 1.618

We use the golden ratio, approximately 1.618, as a default value for this.

When working out sizes for the image, the system will use the following values, of preference:

• the width or height set in the Thumbnail options

• Autoscale

• the Width and Height

We recommend setting width or height values around a placeholder so when the plugin uses Autoscale it can discover them:

{% with 720 as width and 480 as height %}
    {% placeholder content %}
{% endwith %}

Further configuration can be achieved through the django Filer settings.
