如何在应用程序中创建桶填充工具？

Question

我怎样才能在flex中绘制应用程序中的桶填充工具？

case FILL: 
     var b:BitmapData = new BitmapData(width, height); 
     b.draw(this); 
     b.lock(); 
     var from:uint = b.getPixel(x,y); 

     var q:Array = []; 

    var xx:int; 
    var yy:int; 
      var w:int = b.width; 
     var h:int = b.height; 
     q.push(y*w + x); 
     while (q.length != 0) { 
       var xy:int = q.shift(); 
     xx = xy % w; 
      yy = (xy - xx)/w; 
      if (b.getPixel(xx,yy) == from) { 
       b.setPixel(xx,yy,SolidColorStroke(stroke).color); 
       if (xx != 0) q.push(xy-1); 
        if (xx != w-1) q.push(xy+1); 
       if (yy != 0) q.push(xy-w); 
       if (yy != h-1) q.push(xy+w); 
       } 
      } 
      b.unlock(null); 
      break;

你有没有试着用Bitmapdata.floodFill？
