Gmagick::blurimage is a method in Gmagick that allows blurring an image using a specified radius and sigma. The sigma value determines the amount of blurring to be applied.

Here is an example of how you can use Gmagick::blurimage in PHP:

php
// Create a new Gmagick object and read an image file
$image = new Gmagick();
$image->readImage('path-to-your-image-file.jpg');

// Apply blur to the image
$image->blurImage(10, 5);

// Display or save the blurred image
header('Content-type: image/jpeg');
echo $image;

// Or save it to a file
$image->writeImage('path-to-save-blurred-image.jpg');


In the above example, the blurImage method is used on a Gmagick object called $image. The first parameter passed to blurImage is the radius, which determines the size of the blurring kernel. The second parameter is the sigma, which controls the amount of blurring applied.

You can adjust the radius and sigma values to achieve different levels of blurring.
