Introduction

Imagick is a native php extension to create and modify images using the ImageMagick API.

Examples

Imagick makes image manipulation in PHP extremely easy through an OO interface. Here is a quick example on how to make a thumbnail:

Example 1. Creating a thumbnail in Imagick <?php header('Content-type: image/jpeg'); $image = new Imagick('image.jpg'); // If 0 is provided as a width or height parameter, // aspect ratio is maintained $image->thumbnailImage(100, 0); echo $image; ?>

Using SPL and other OO features supported in Imagick, it can be simple to resize all files in a directory (useful for batch resizing large digital camera images to be web viewable). Here we use resize, as we might want to retain certain meta-data:

Example 2. Make a thumbnail of all JPG files in a directory <?php $images = new Imagick(glob('images/*.JPG')); foreach($images as $image) {     // Providing 0 forces resizeImage to maintain aspect ratio     $image->resizeImage(1024,0); } $images->writeImages(); ?>
