Actionscript 3 动作脚本对齐图形线条样式笔划？

是否可以将图形的笔划与actionscript对齐？例如，以下代码创建了一个黑色圆形矩形，其灰色笔划自动居中对齐

var t:Sprite = new Sprite();
t.graphics.lineStyle(5, 0x555555);
t.graphics.beginFill(0, 1);
t.graphics.drawRoundRect(25, 25, 200, 75, 25, 25);
t.graphics.endFill();

lineStyle函数似乎不提供任何用于对齐笔划的内置功能。在Adobe Illustrator中，可以将笔划对齐为居中（一半在填充物内/一半在填充物外）、内部（填充物内的边界）或外部。（在填充外部加边框）。

闪存中不支持此操作（即使在GUI中也不支持）。您必须修改drawRoundRect参数以模拟此效果

var strokeWidth:Number = 5;
var strokeAlign:String = 'outer';
var t:Sprite = new Sprite();
t.graphics.lineStyle(strokeWidth, 0x555555);
t.graphics.beginFill(0, 1);
if (strokeAlign == 'outer') {
    t.graphics.drawRoundRect(25 - strokeWidth / 2, 25 - strokeWidth / 2, 200 + strokeWidth, 75 + strokeWidth, 25 + strokeWidth / 2, 25 + strokeWidth / 2);
} else if (strokeAlign == 'inner') {
    t.graphics.drawRoundRect(25 + strokeWidth / 2, 25 + strokeWidth / 2, 200 - strokeWidth, 75 - strokeWidth, 25 - strokeWidth / 2, 25 - strokeWidth / 2);
} else {
    t.graphics.drawRoundRect(25, 25, 200, 75, 25, 25);
}
t.graphics.endFill();

Flash中不支持这一点（即使在GUI中也不支持）。您必须修改drawRoundRect参数以模拟此效果

var strokeWidth:Number = 5;
var strokeAlign:String = 'outer';
var t:Sprite = new Sprite();
t.graphics.lineStyle(strokeWidth, 0x555555);
t.graphics.beginFill(0, 1);
if (strokeAlign == 'outer') {
    t.graphics.drawRoundRect(25 - strokeWidth / 2, 25 - strokeWidth / 2, 200 + strokeWidth, 75 + strokeWidth, 25 + strokeWidth / 2, 25 + strokeWidth / 2);
} else if (strokeAlign == 'inner') {
    t.graphics.drawRoundRect(25 + strokeWidth / 2, 25 + strokeWidth / 2, 200 - strokeWidth, 75 - strokeWidth, 25 - strokeWidth / 2, 25 - strokeWidth / 2);
} else {
    t.graphics.drawRoundRect(25, 25, 200, 75, 25, 25);
}
t.graphics.endFill();
