Gmagick::setfilename() is a method in PHP that is used to set the filename of a Gmagick object. The Gmagick extension is used for creating, modifying, and manipulating images in various formats.

When using Gmagick::setfilename(), you need to provide the filename as a parameter to the method. This filename refers to the file that you want to read or write with Gmagick.

Here is an example that demonstrates the usage of Gmagick::setfilename():

php
$image = new Gmagick();

// Set the filename of the Gmagick object
$image->setfilename('path/to/image.jpg');

// You can perform operations on the image using other Gmagick methods
$image->resizeimage(300, 200, Gmagick::FILTER_LANCZOS, 1);

// Save the modified image
$image->write('path/to/modified_image.jpg');


In the above example, we create a new Gmagick object and set the filename using the setfilename() method. Then, we apply a resize operation to the image and save the modified image using the write() method.

Make sure you have the Gmagick extension installed and enabled in your PHP environment to use this functionality.
