## Features

- [x] Small but complete, only`200`lines of code. 

- [x] Allow to control display quality, memory usage, loop time and display progress.

- [x] Have a great performance on memory and cpu usage. 

- [x] Using asynchronous image decoding to reduce the main thread CPU usage.

## Usage

```swift

/* Create AImage with URL */

let image = AImage(url: Bundle.main.url(forResource: "test", withExtension: "gif")!)

/* Create AImageView */

let imageview = AImageView(frame:CGRect(x: 0.0, y: 50.0, width: 380.0, height: 212.0))

/* Add AImage to AImageView */

imageview.add(image: image!)

/* Start displaying animated image */

imageview.play = true

...

...

/* Stop displaying animated image */

imageview.play = false

```
