stxnext.grayscale

Introduction

The stxnext.grayscale package is an add-on Product for Plone that gives the possibility of displaying the web content of the site in the grayscale colors.

Colors transformation

The images are transformed on-the-fly using the PIL library.

The css and html documents are transformed with regular expression to substitute the colors definitions with their grayscale equivalent values.

In Plone 4 (with plone.resource package installed) the transformed resources (images, css files) are cached in the file system to avoid multiple transformation of the same resource.

Installation

Plone 3

For sites based on Plone 3.x use stxnext.grayscale v 1.0.0

Plone 4

1. Add stxnext.grayscale to your plone.recipe.zope2instance section's eggs. Define the resources parameter to point to the existing directory where the transformed resources will be stored to avoid multiple transformation of the same resource:

[instance]
recipe = plone.recipe.zope2instance
...
resources = ${buildout:directory}/var/resources
...
eggs =
    ...
    stxnext.grayscale
  1. Install the Product via portal_quickinstaller

Configuration

In the stxnext.grayscale tool's control panel (/@@grayscale_settings) choose the Plone skins to be transformed to grayscale colors.
