Flash AS3，文本抗锯齿是由代码控制的吗？

文本抗锯齿是由代码控制的，还是嵌入的？我想要做的是获取别人制作的 swf 文件，找到 swf 文件中的所有文本，并将所有抗锯齿模式从动画更改为可读。在as3中也是这样吗？老实说，我还没有在代码中尝试过任何抗锯齿功能。

您可以将文本字段的 antiAliasType 设置为“高级”，这样您就可以对清晰度和厚度进行精细控制。但是，必须嵌入字体（包括：文本字段必须将 embedFonts 设置为 true，TextFormat 对象的字体属性必须与嵌入字体的 fontName 完全相同，并且字体必须已编译）。所以从技术上来说“这可能吗？” - 是的。它有可能按照你想要的方式工作吗？不，除非您打算使用您知道已经使用嵌入字体的 swiff。那么您需要从加载的 swiff 中获取所有文本字段（您可以使用如下内容： http:// upshots.org/?p=107，然后使用 array.filter 只返回 TextField 对象），然后应用您的逻辑。

编辑：添加代码示例

// assuming you're using the DisplayList class linked above
var request:URLRequest = new URLRequest("textfields.swf");
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandler, false, 0, true);
loader.load(request);

function completeHandler(event:Event):void{

    var content:DisplayObjectContainer = event.target.loader.content as DisplayObjectContainer;
    addChild(content);

    var children:Array = new DisplayList(content);
    children = children.filter(function(item:Object, index:int, array:Array):Boolean {
        return item is TextField;
    });
    children.forEach(function(item:Object, index:int, array:Array):void {
        var textfield:TextField = item as TextField;
        textfield.antiAliasType = AntiAliasType.ADVANCED;
        textfield.sharpness = 100;
        textfield.thickness = 100;
    });
}

刚刚运行了快速测试 - 按描述工作。

you can set the antiAliasType of a textfield to 'advanced', which gives you fine control over sharpness and thickness. however, the fonts must be embedded (inclusive: the textfield must have embedFonts set to true, the TextFormat objects must have font properties exactly equal to the fontName of the embedded font, and the fonts must be already compiled). so technically 'is it possible?' - yes. is it likely to work the way you want it to? no, unless you plan on working with a swiff that you know is using embedded fonts already. then you'll need to grab all the textfields from the loaded swiff (you could use something like this: http://upshots.org/?p=107, then use array.filter to get back only TextField objects), then apply your logic.

EDIT: adding code sample

// assuming you're using the DisplayList class linked above
var request:URLRequest = new URLRequest("textfields.swf");
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandler, false, 0, true);
loader.load(request);

function completeHandler(event:Event):void{

    var content:DisplayObjectContainer = event.target.loader.content as DisplayObjectContainer;
    addChild(content);

    var children:Array = new DisplayList(content);
    children = children.filter(function(item:Object, index:int, array:Array):Boolean {
        return item is TextField;
    });
    children.forEach(function(item:Object, index:int, array:Array):void {
        var textfield:TextField = item as TextField;
        textfield.antiAliasType = AntiAliasType.ADVANCED;
        textfield.sharpness = 100;
        textfield.thickness = 100;
    });
}

just ran a quick test - works as described.
