Imagick Image Library

Introduction

Warning

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

ImageMagick® is a software suite to create, edit, and compose bitmap images.. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF.

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(1000);

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 thumbnailImage to maintain aspect ratio
    
$image->thumbnailImage(1024,0);

}

$images->writeImages();

?>
