Imagick::cropImage() is a method in PHP's ImageMagick extension (Imagick) that allows you to crop an image.

To use Imagick::cropImage(), you need to provide the following parameters:

1. $width: The width of the cropped image.
2. $height: The height of the cropped image.
3. $x: The x-coordinate of the start of the crop region.
4. $y: The y-coordinate of the start of the crop region.

Here's an example that demonstrates the usage of Imagick::cropImage():

php
<?php
// Create an Imagick object
$image = new Imagick('input.jpg');

// Crop the image
$width = 200;
$height = 200;
$x = 100;
$y = 100;
$image->cropImage($width, $height, $x, $y);

// Save the cropped image
$image->writeImage('output.jpg');

// Clean up
$image->destroy();
?>


In this example, we load an image ("input.jpg") using the Imagick class. We then call the cropImage() method on the image object, specifying the dimensions and position of the crop region. Finally, we save the cropped image as "output.jpg" and clean up by destroying the image object.

You can modify the values of $width, $height, $x, and $y according to your specific requirements.
