Watimage is a PHP class to resize, rotate and apply watermark to images.

It was initially thought as a CakePHP Component, but now is a standalone class, so you can use it everywhere :D

With composer:

composer require elboletaire/watimage 1.0.0

As a git submodule:

git submodule add https://github.com/elboletaire/Watimage.git Vendor/Elboletaire/Watimage

// In top of your document (if you use composer's autoloader)
use Elboletaire\Watimage\Watimage;
// If you're not using composer's autoloader, then require it manually
// require_once 'Vendor/Elboletaire/Watimage/src/Watimage.php';

$wm = new Watimage();
$wm->setImage('original_file.png');
$wm->setWatermark('watermark.png');

// Resize image to 400x400px
$wm->resize(array('type' => 'resizecrop', 'size' => 400));

// Flip it horitzontally
$wm->flip('horizontal');

// Rotate 90 degrees
$wm->rotate(90);

// Apply the watermark
$wm->applyWatermark();

// Generate and save image
if ( !$wm->generate('result.png') ) {
    // handle errors...
    print_r($wm->errors);
}

You have an example.php file with more examples.

Currently there are only methods to visually check that all images are properly generated.

To run them just cd into the visual tests folders and run the run_them_all.php script:

cd tests/visual
php run_them_all.php

It will generate a bunch of files in tests/visual/results where you can check if everything is running as expected.
