Imagick is a powerful image processing library.

It is actually a brief introduction to the main functions of imagick, or an example of functional functions that I think are more practical.

Because of my limited level of English, I use a more popular or close-to-use language to describe.

First, I would like to enjoy a set of dazzling results:

Example:

<?php
ini_set('display_errors',1);
header('Content-type: image/jpeg');
$image = new Imagick('1.jpg');
$image->rollImage(20,39);
echo $image;
?>

Example:
