有没有办法让在ActionScript字形的实际边界框？ [英] Is there a way to get the actual bounding box of a glyph in ActionScript?

问题描述

我学习ActionScript / Flash中。我喜欢用文字来打，并且已经做了很多这种事情与精湛的Java2D的API。

I'm learning ActionScript/Flash. I love to play with text, and have done a lot of that kind of thing with the superb Java2D API.

的事情之一，我想知道的是里，就是这样，你在画的字形？ TextField类提供了方法的getBounds 和使用getCharBoundaries ，但这些方法返回的矩形远远超出的实际边界整个文本对象或个性，分别为。

One of the things I like to know is "where, exactly, are you drawing that glyph?" The TextField class provides the methods getBounds and getCharBoundaries, but these methods return rectangles that extend far beyond the actual bounds of the whole text object or the individual character, respectively.

var b:Sprite = new Sprite();
b.graphics.lineStyle(1,0xFF0000);
var r:Rectangle = text.getCharBoundaries(4);
r.offset(text.x, text.y);
b.graphics.drawRect(r.x,r.y,r.width,r.height);
addChild(b);

b = new Sprite();
b.graphics.lineStyle(1,0x00FF00);
r = text.getBounds(this);
b.graphics.drawRect(r.x,r.y,r.width,r.height);
addChild(b);

有没有什么办法让有关的文字字形的ActionScript中的实际可视范围更precise信息？

Is there any way to get more precise information about the actual visual bounds of text glyphs in ActionScript?

推荐答案

没有合理可能性在Flash 9 - 理查德的回答是一个聪明的解决方法，虽然可能完全不适合生产code（因为他提到了）： ）

Not reasonably possible in Flash 9 -- Richard's answer is a clever work-around, though probably completely unsuitable for production code (as he mentions) :)

如果你有机会到Flash 10，检查出新的文本引擎类的，尤其是一个TextLine。

If you have access to Flash 10, check out the new text engine classes, particularly TextLine.
