Imagick::getFormat is a method in PHP's Imagick extension, which is used to retrieve the format of an image. It returns a string representing the format of the image.

Here's an example of how you can use it:

php
$imagePath = 'path/to/your/image.jpg';

// Create a new Imagick object
$image = new Imagick($imagePath);

// Get the format of the image
$format = $image->getFormat();

// Output the format
echo "The format of the image is: " . $format;


In this example, you first create a new Imagick object by passing the image path to its constructor. Then, you call the getFormat method on the image object to retrieve the image format. Finally, you can use echo to output the format.

Please note that Imagick supports various image formats such as JPEG, PNG, GIF, etc., and the getFormat method will return the specific format of the image being processed.
