This is currently a work in progress and not completly stable. API not yet final so new versions can break code.!

voronoi-obfuscate

Create an obfuscated version of a source image by using a Voronoi diagram (see. https://en.wikipedia.org/wiki/Voronoi_diagram)

Getting Started

Maybe you feel like making "art" from your images or you just like your images obfuscated

Input (200x200px):

Results:

Reduce Size to 100x100px

Non proportional resize to 400x100px

Non proportional resize to 100x400px

Installing

composer require dkerner/voronoi-obfuscate "@dev"

Usage

// create an obfuscated version of demo.jpg, store it as out.jpg 
// and create 500 points
VoronoiObfuscator::createFromImagePath('demo.jpg', 'out.jpg', 500);
 
// use config and resize the resulting image
$config = new ObfuscatorConfig();
$config->setImagePath('demo.jpg')
    ->setOutputPath('out.jpg')
    ->setCellCount(1000)
    ->setOutputSize(400,800);

VoronoiObfuscator::createFromConfig($config);

Or use an image resource as input and output

$config = new ObfuscatorConfig();
 
// set input
$imageRessource = imagecreatefromjpeg('demo.jpg');
$config->setInputResource( $imageRessource )
    ->setCellCount(100)
    ->setOutputSize(100,100);
    
$processedImageRessource = VoronoiObfuscator::processImage($config);
 
// use it further however needed
imagejpeg( $processedImageRessource, 'out_processed.jpg');
