imageview under pulsator with swift 4

Question

I am trying to show an UIImage with pulse effect, for this I use pulsator framework. but the UIImage is under the pulsator, now I want to know if it is possible to set the UIImage on pulsator effect?

This is my code:

let img = UIImage(named: "img_usuario")
let img_view = UIImageView(image: img)
img_view.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
img_view.layer.cornerRadius = img_view.frame.size.height/2
img_view.layer.masksToBounds = true
let pulsator = Pulsator()
pulsator.radius = 50
pulsator.numPulse = 3
pulsator.position = img_view.center
pulsator.backgroundColor = UIColor.rgb(red: 220, green: 5, blue: 5, alpha: 1).cgColor
img_view.layer.addSublayer(pulsator)
pulsator.start()

and I also want to know how I make the effect pulse is exceeds the size of the image like the demo

thanks in advance

For this kind of stuff, you should probably submit an issue. You might get a better and quicker answer that way.

From what I seen in the example, you should do this:

img_view.layer.superlayer?.insertSublayer(pulsator, below: img_view.layer)

This might just be caused by an outdated README.

Also, if it does not exceed the image view, try setting the radius to a larger number.
