EEA Depiction

EEA Depiction (formerly valentine.imagescales) is a generic system for creating thumbnails/image representations for content types, both those provided by Plone, and custom ones. To make it work for a content type, three adapters need to be provided:

  1. ImageView that retrieves an image in the desired scale.
  2. ImageTag that returns the HTML tag for the image
  3. ImageLink that returns the HTML link to the image.

Installation

zc.buildout

If you are using zc.buildout and the plone.recipe.zope2instance recipe to manage your project, you can do this:

  • Update your buildout.cfg file:

    [instance]
    ...
    eggs =
      ...
      eea.depiction
    
    zcml =
      ...
      eea.depiction-overrides
      eea.depiction
    
  • Re-run buildout, e.g. with:

    $ ./bin/buildout
    

You can skip the ZCML slug if you are going to explicitly include the package from another package's configure.zcml file.

How to specify fallback preview images

eea.depiction 0.3 introduces the concept of fallback images when the regular image traversal fails. The logic works like this:

  1. Look for an image returned by the contexts 'imgview' adapter
  2. If the imgview crashes, isn't found or can not locate/generate an image, we continue by checking if there's an image specified for any of the contexts interfaces.
  3. If there's no fallback image, we look for an image for the context portal type, e.g. article, news-item, document. This should be placed in the 'portal_depiction' utility (Site Setup > Depiction Library)
  4. Uses the generic content type image, i.e. portal_depiction/generic

Thus:

  1. To map a fallback image to a portal type, place it in this folder and name it after the portal type.
  2. To map a fallback image to an interface just add a named-utility for IDepictionVocabulary (see eea.depiction.vocabularies)
