The GIFPlayer

The GIFPlayer class is used to play the gif animation.

It can load gif file from an URLRequest object or a ByteArray object.

gifplayer用于播放gif图片，它通过urlrequest对象，或者图片的二进制对象加载gif。

    package  
    { 
            import flash.display.Sprite; 
            import flash.net.URLRequest; 
            import org.gif.player.GIFPlayer; 
             
            public class Main extends Sprite 
            { 
                    public function Main():void 
                    { 
                            var request:URLRequest = new URLRequest("diego.gif"); 
                             
                            var player:GIFPlayer = new GIFPlayer(); 
                            player.load(request); 
                             
                            addChild(player); 
                    } 
            } 
    } 


The GIFEncoder

The GIFEncoder class use to create a gif file by frames.

Example(draw two frames and add to GIFEncoder then play the gif data by GIFPlayer):

gif解码器，用于根据帧生成gif。
