Flash CS3 / FP10 中的文本字段抗锯齿导致文本闪烁和“溢出”？

我在 Flash 中遇到了一个小的图形故障。它似乎在 FP9 - 通过 Flash CS3 导出，和 FP10 - 通过 Flex 4 beta SDK 导出。

该故障/问题表现为在某些条件下以小点尺寸“开花”的嵌入文本。基本上看起来抗锯齿在一定程度的文本亮度下变得更厚。我在下面做了一个小测试用例。（显然）您需要在编译的 SWF 中嵌入 Arial 字体，下面的代码才能工作。

var myText:TextField = new TextField();
myText.embedFonts = true;
myText.antiAliasType = AntiAliasType.ADVANCED;
myText.autoSize = TextFieldAutoSize.LEFT;
var myFormat:TextFormat = myText.getTextFormat();
myFormat.size = 8;
myFormat.font = 'Arial';
myFormat.color = 0x663300;
myText.defaultTextFormat = myFormat;
myText.text = 'Bloom Example';
addChild(myText);
var composit:ColorTransform = new ColorTransform();
var timestamp:Number = getTimer();
function enterFrame (event:Event):void{
    var n:Number = (getTimer() - timestamp) / 1000.0;
    composit.redMultiplier = 1-n;
    composit.greenMultiplier = 1-n;
    composit.blueMultiplier = 1-n;
    composit.redOffset = 250 * n;
    composit.greenOffset = 250 * n;
    composit.blueOffset = 0;
    myText.transform.colorTransform = composit;
    if ( n >= 1 ) removeEventListener(Event.ENTER_FRAME, enterFrame);
};
addEventListener(Event.ENTER_FRAME, enterFrame);

更改为 AntiAliasType.NORMAL 并不是真正的选择，因为它会使文本在这种大小下可读性较差。

任何帮助找到此问题的适当解决方案将不胜感激。

I have run into a small graphics glitch in Flash. It seems to be both in FP9 - Exported via Flash CS3, and FP10 - Exported via the Flex 4 beta SDK.

The glitch / problem manifests itself as embedded text at a small point size "blooming" under certian conditions. It basically looks like the antialiasing becomes fatter at some level of text brightness. I have made a small test case below. (Obviously) You will need to embed the Arial font in your compiled SWF for the below code to work.

var myText:TextField = new TextField();
myText.embedFonts = true;
myText.antiAliasType = AntiAliasType.ADVANCED;
myText.autoSize = TextFieldAutoSize.LEFT;
var myFormat:TextFormat = myText.getTextFormat();
myFormat.size = 8;
myFormat.font = 'Arial';
myFormat.color = 0x663300;
myText.defaultTextFormat = myFormat;
myText.text = 'Bloom Example';
addChild(myText);
var composit:ColorTransform = new ColorTransform();
var timestamp:Number = getTimer();
function enterFrame (event:Event):void{
    var n:Number = (getTimer() - timestamp) / 1000.0;
    composit.redMultiplier = 1-n;
    composit.greenMultiplier = 1-n;
    composit.blueMultiplier = 1-n;
    composit.redOffset = 250 * n;
    composit.greenOffset = 250 * n;
    composit.blueOffset = 0;
    myText.transform.colorTransform = composit;
    if ( n >= 1 ) removeEventListener(Event.ENTER_FRAME, enterFrame);
};
addEventListener(Event.ENTER_FRAME, enterFrame);

You can see an example of the problem by rolling over the graphical element here: http://bandcamp.fieldsofnoise.org/dump/bloom.swf

It's not really an option to change to AntiAliasType.NORMAL as it makes the text way less readable at this point size.

Any help finding an appropriate resolution to this problem would be appreciated.
