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。
