Question

AS3如何实现图片平铺

Answer 1

package
{
import flash.geom.Rectangle;

import mx.graphics.BitmapFill;
import mx.skins.ProgrammaticSkin;
import flash.text.StyleSheet;

public class RepeatBackground extends ProgrammaticSkin {
public function RepeatBackground() {
}
override protected function updateDisplayList(w:Number, h:Number):void {
super.updateDisplayList(w,h);

graphics.clear();
var b:BitmapFill = new BitmapFill();
b.source = getStyle("backgroundImage");;
b.begin(graphics,new Rectangle(0,0,w,h));
graphics.drawRect(0,0,w,h);
b.end(graphics);
}
}
}

使用方法也很简单，只需要设置一下css就可以了
Application
{
backgroundImage: Embed(source="assets/bg1.gif");
border-skin:ClassReference("RepeatBackground");
}

可能有些不一样，仅供参考
