Idolon Module for myMVC

Just add this module to your myMVC and get it run with this 3 Steps:

This is a Module for myMVC which integrates the Idolon Image Server (https://github.com/gueff/idolon). Image Variation Requests become very easy.

Dependencies

• Linux
• php >= 7.4
  • execution of shell_exec()
• imagemagick
• gueff/idolon 1.1.2
• myMVC 3.2.x
  • ZIP: https://github.com/gueff/myMVC/archive/refs/heads/3.2.x.zip

1. Download this Repository

and place it inside myMVC's modules folder. Name it "Idolon". At the end it must look like this:

    application
    config
    modules
        Idolon
            Controller
            etc
            Event
            Model
            install.sh
            README.md
    public
    composer.json
    myMVC.phar
    README.md

2. Add Idolon Library

therefore, run install.sh

./install.sh

3. Add Idolon Config

3.1. create a new config file

Just create a new file by copying the file etc/config/Idolon/config/develop.example to etc/config/Idolon/config/develop.php

3.2. Modify the config

Modify the config so that it fit your needs.

This is the Content of the Config file idolon.php

// float numbers need to be presented C-style
setlocale(LC_NUMERIC, 'C');

/**
 * Idolon config
 */
$aConfig['MODULE_IDOLON'] = array(

    // Token
    // This is the string directly located after domain which indicates an image request
    // e.g. http://www.example.com/image/screenshot/png/200/100/1/
    // Here in this example, "@image" ist the token
    // Note: Idolon will automatically listen for (/@image/) then.
    '@image' => array(
        'IDOLON_IMAGE_PATH' => $aConfig['MVC_BASE_PATH'] . '/public/images/default/',
        'IDOLON_CACHE_PATH' => $aConfig['MVC_CACHE_DIR'] . '/Idolon/',
//        'IDOLON_MAX_CACHE_FILES_FOR_IMAGE' => 10,
//        'IDOLON_PREVENT_OVERSIZING' => true,
    ),

    // Other Images
    '@other' => array(
        'IDOLON_IMAGE_PATH' => $aConfig['MVC_BASE_PATH'] . '/public/images/other/',
        'IDOLON_CACHE_PATH' => $aConfig['MVC_CACHE_DIR'] . '/Idolon/',
//        'IDOLON_MAX_CACHE_FILES_FOR_IMAGE' => 10,
//        'IDOLON_PREVENT_OVERSIZING' => true,
    ),

    // how many variations of an image should be stored for maximum
    'IDOLON_MAX_CACHE_FILES_FOR_IMAGE' => 10,

    /**
     * if activated,
     * an image cannot resize to higher values than its dimensions, but only to lower ones
     * true: prevents resizing to higher x or y values than original has
     */
    'IDOLON_PREVENT_OVERSIZING' => true,
);

4. Activate Idolon via Event Listener

just add a file idolon.php to the modules/{YOUR_MODULE}/etc/event/ folder:

<?php

#-------------------------------------------------------------
# declare bindings

$aEvent = [
    'mvc.controller.init.before' => array(
        function(\MVC\DataType\DTArrayObject $oDTArrayObject) { // enable Idolon Image Server
            \Idolon\Event\Index::startIdolon($oDTArrayObject);
        }
    ),
];

#-------------------------------------------------------------
# process: bind the declared ones

\MVC\Event::processBindConfigStack($aEvent);

Example

Due to the Config, this will serve the Image screenshot1.png from the public folder /images/ with 750x352 px:

<!-- request image with original width + heigt -->
<img src="http://www.example.com/@image/screenshot1/png/">

<!-- request image with width of 750px; height will be calculated -->
<img src="http://www.example.com/@image/screenshot1/png/750/">

<!-- request image with width of 750px and height of 352px; redirect with proper dimension request if necessary -->
<img src="http://www.example.com/@image/screenshot1/png/750/300/1/">

Explanation

• The Request http://www.example.com/@image/screenshot1/png/750/352/1/is made.
• The Event Listener (\MVC\Event::BIND('mvc.controller.before', function(){..}) checks the current Request.
• If the first string after the domain is @image this means an image request has been detected.
• So in this Example, the Request http://www.example.com/@image/screenshot1/png/750/352/1/ will be handled by Idolon Module.
