A behavior for Dexterity-based content types to add a featured image for sharing content on social media.

Suppose you are running The Planet, a news portal that has a bunch of editors focused on getting news on different topics, like Economy, Health or Sports.

Sometimes your news have a great catchphrase, and you want to add more appeal in this phrase writing it into the image you share.

This package allows you to automatize this image creation with the text embedded, and set this image as a featured image of your news.

This package uses PhantomJS to create the featured image.

To enable this package in a buildout-based installation:

1. Edit your buildout.cfg and add add the following to it:

   [buildout]
   ...
   eggs =
       collective.behavior.featuredimage
   
   parts =
       ...
       env
       node
   
   [env]
   recipe = collective.recipe.environment
   
   [instance]
   ...
   environment-vars +=
       PATH ${buildout:bin-directory}:${env:PATH}
   
   [node]
   recipe = gp.recipe.node
   npms = phantomjs-prebuilt
   scripts = phantomjs

After updating the configuration you need to run ''bin/buildout'', which will take care of updating your system.

Go to the 'Site Setup' page in a Plone site and click on the 'Add-ons' link.

Check the box next to collective.behavior.featuredimage and click the 'Activate' button.

This add-on includes a behavior to add four extra fields on Dexterity-based content types:

Enabled

Used to indicate that this content should use the featured image. Enabled by default.

Quote

The catchphrase you want to be embedded into the image. Uses the title field (if available) by default.

Author

The author of the catchphrase.

Featured Image

The featured image generated. This field is read-only.

Add the base image in the control panel configlet.

• In 'Site Setup', select the Dexterity Content Types configlet
• Select your content type
• Go to Behaviors tab and select Featured Image

A new fieldset called Featured Image will be present in the edit form of your content type.

The buildout configuration already installs PhantomJS and makes it available by updating the PATH environment variable.

We use yeoman and grunt to build static files, to start grunt watch run:

buildout_dir$ ./bin/grunt_watch

Then open the browser at http://localhost:9000 and edit the files at directory yeoman/app to customize the static files.

To build the static files run:

buildout_dir$ ./bin/grunt_build
