You can install this plugin into your CakePHP application using composer.
The recommended way to install composer packages is:
composer require rindula/luminance
To activate the Plugin in CakePHP, you have to add the following to the end of config/bootstrap.php
:
Plugin::load('Luminance');
To use this Helper in a view, you have two options:
- Add the Helper to one Controller only
add the following code to your controller:
public $helpers = ['Luminance'];
- Add it globally to your AppView
Add the following to the initialize method of src/View/AppView.php
:
$this->loadHelper('Luminance.Luminance');
Add this to the initialize function of the Controller you need the Component in, below parent::initialize()
:
$this->loadComponent('Luminance.Luminance')
Once the respective setup is done you can use it like this:
$color = $this->Luminance->getContrastColor($hexColor);
$color
then contains the hex color of the contrast color, which is either black (#000000) or white (#FFFFFF).
