PHP Gmagick Functions Complete Reference

Gmagick is the PHP extension used to create, modify and obtain meta information of an image using GraphicsMagick API. The Gmagick consists of Gmagick, GmagickDraw, and GmagickPixel class.

Example: Below programs illustrate the Gmagick::getpackagename() function in PHP:

Original Image:

PHP

<?php

// Create new Gmagick object
$im = new Gmagick(
'https://media.geeksforgeeks.org/wp-content/uploads/geeksforgeeks-15.png');

// Using getpackagename function
echo $im->getpackagename();

?>

Output:

GraphicsMagick
