The purpose of this library is to provide a rough outline for an image that has an alpha background.
The outline is provided as a UIBezierPath. The way to obtain it is via one of two methods provided an a extension to UIImageView:
@IBOutlet weak imageView : UIImageView!
override func viewDidAppear() {
super.viewDidAppear()
imageView.getBezierOutline(10, margin: 10) // synchronous
imageView.getBezierOutlineAsync(10, margin : 10) { (bezier : UIBezierPath) -> Void in
// completion block
}
}
To run the example project, clone the repo, and run pod install from the Example directory first.
