如何用AS消除位图锯齿
http://www.cnblogs.com/bjsky/archive/2009/09/24/1573133.html问：最近做了一个Flash的电子相册，遇到一个很棘手的问题，就是通过AS动态载入的图片在缩放的时候出现模糊和锯齿，由于这些位图是通过AS从外部载入进来的，不能在Flash制作时通过修改库里图片的属性来消除锯齿。所以求一个解决之法，小弟在此不胜感激了。
ycccc8202(春叶飘零) 答：外部加载的可以通过bitmap来进行解决。主要用到MovieClip.attachBitmap中的一个smooth参数的设置，来进行平滑处理。
/*****进行消锯齿与不消锯齿的对比*****/ import flash.display.BitmapData; /*************加载******************/ var container1:MovieClip = createEmptyMovieClip("container1", getNextHighestDepth()); var container2:MovieClip = createEmptyMovieClip("container2", getNextHighestDepth()); var loader1:MovieClipLoader = new MovieClipLoader(); var loader2:MovieClipLoader = new MovieClipLoader(); var obj:Object = new Object(); obj.onLoadInit = function(target:MovieClip) { trace("onLoadInit"); loaderDispose(target); }; loader1.addListener(obj); loader1.loadClip("1.jpg", container1); loader2.addListener(obj); loader2.loadClip("1.jpg", container2); /**********图片处理***************/ var bitmapLoader1:MovieClip = createEmptyMovieClip("Bloader1", getNextHighestDepth()); var bitmapLoader2:MovieClip = createEmptyMovieClip("Bloader2", getNextHighestDepth()); var bitmap1:BitmapData; var bitmap2:BitmapData; function loaderDispose(mc:MovieClip) { mc._visible = false; /*******不平滑*******/ if (mc._name == "container1") { bitmap1 = new BitmapData(mc._width, mc._height, true, 0x00FFFFFF); bitmap1.draw(mc); bitmapLoader1.attachBitmap(bitmap1, 0); bitmapLoader1._x = -50; bitmapLoader1._xscale = bitmapLoader1._yscale=250; } else { /******平滑处理*******/ bitmap2 = new BitmapData(mc._width, mc._height, true, 0x00FFFFFF); bitmap2.draw(mc); bitmapLoader2.attachBitmap(bitmap2, 1, "auto", true); //主要就是这个smooth参数，true表示平滑 bitmapLoader1._x = -50; bitmapLoader2._y = 300; bitmapLoader2._xscale = bitmapLoader2._yscale=250; } }
