Awesome
Features
- Small but complete, only
200lines of code. - Allow to control display quality, memory usage, loop time and display progress.
- Have a great performance on memory and cpu usage.
- Using asynchronous image decoding to reduce the main thread CPU usage.
Usage
/* 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
Benchmark
Compared with Gifu and Apple's example code.
Test1: Display view.gif
| Library | CPU | Memory |
|---|---|---|
| Apple's Example Code | <img src="https://wangjwchn.github.io/image/apple-view-cpu.png" width = "1000" height = "150" /> | <img src="https://wangjwchn.github.io/image/apple-view-mem.png" width = "600" height = "120" /> |
