   How do I use IMagick?

   • When using the Imagick library, start with small radius and sigma values and gradually increase them to avoid over-blurring. For example, begin with a radius of 3 and a sigma of 2, adjusting incrementally until you achieve the desired effect. Resize or compress images before applying blur operations to reduce processing time.

   • The Imagick class has the ability to hold and operate on multiple images simultaneously. This is achieved through an internal stack. There is always an internal pointer that points at the current image. Some functions operate on all images in the Imagick class, but most operate only on the current image in the internal stack.

You can customize the blurring intensity by setting the effect parameter (e_blur_faces in URLs) to a value between 1 and 2000, where a higher value results in a more pronounced blur.
