属性详细信息

emBox

属性
public var emBox:Rectangle

语言版本: ActionScript 3.0
运行时版本: Flash Player 10, AIR 1.5, Flash Lite 4

emBox 值表示字体的设计间隔,该值用于相对于罗马字基线放置中文、韩语或日语字型。通常为方形,大小为字体的点值。emBox 的原点(坐标 0,0)设置为左边缘和矩形的罗马字基线。例如,对于 10 点字体,emBox 可以是值为 [0,-8.8, 10, 1.2] 的 rect [L,T,R,B]。

lineGap

属性 
public var lineGap:Number

语言版本: ActionScript 3.0
运行时版本: Flash Player 10.3, AIR 2.6

lineGap 值是建议的行间隔。

此值由字体设计器设置,并且可随字体的不同而有所不同。在多脚本字体中,不同的行间隔可能适用于不同的脚本;不存在适用于所有脚本的单一值。此外,特殊脚本的不同种类的文本用法(例如,日语文本是否采用 ruby 进行批注)可能需要不同的行间隔。

strikethroughOffset

属性 
public var strikethroughOffset:Number

语言版本: ActionScript 3.0
运行时版本: Flash Player 10, AIR 1.5, Flash Lite 4

strikethroughOffset 值是距离删除线的罗马字基线的建议垂直偏移。

请注意,为了找出删除线的位置,应根据行的旋转将此值与行位置相加,或从行位置中减去此值。在具有 TextRotation.ROTATE_0 的行中,strikethrough.y = line.y + strikethroughOffset。在具有 TextRotation.ROTATE_90 的行中,strikethrough.x = line.x - strikethroughOffset

将装饰(例如删除线)应用于 TextLine 时,建议的方法是在要接收装饰的 ContentElement 上指定 eventMirror。作为对 Event.ADDED 事件的响应,TextLineMirrorRegionbounds 可与 strikethroughOffset 结合使用以放置删除线。

相关 API 元素

strikethroughThickness

属性 
public var strikethroughThickness:Number

语言版本: ActionScript 3.0
运行时版本: Flash Player 10, AIR 1.5, Flash Lite 4

strikethroughThickness 值是建议的删除线粗细。

subscriptOffset

属性 
public var subscriptOffset:Number

语言版本: ActionScript 3.0
运行时版本: Flash Player 10, AIR 1.5, Flash Lite 4

subscriptOffset 值是距离下标的罗马字基线的建议垂直偏移。

将 subscriptOffset 值与 ElementFormat.baselineShift 一起使用以设置下标的位置。

相关 API 元素

subscriptScale

属性 
public var subscriptScale:Number

语言版本: ActionScript 3.0
运行时版本: Flash Player 10, AIR 1.5, Flash Lite 4

subscriptScale 值是要应用于下标点值的建议缩放系数。缩放系数 1.0 表示不进行缩放。

superscriptOffset

属性 
public var superscriptOffset:Number

语言版本: ActionScript 3.0
运行时版本: Flash Player 10, AIR 1.5, Flash Lite 4

superscriptOffset 值是距离上标的罗马字基线的建议垂直偏移。

将 superscriptOffset 值与 ElementFormat.baselineShift 一起使用以设置上标的位置。

相关 API 元素

superscriptScale

属性 
public var superscriptScale:Number

语言版本: ActionScript 3.0
运行时版本: Flash Player 10, AIR 1.5, Flash Lite 4

superscriptScale 值是要应用于上标点值的建议缩放系数。缩放系数 1.0 表示不进行缩放。

underlineOffset

属性 
public var underlineOffset:Number

语言版本: ActionScript 3.0
运行时版本: Flash Player 10, AIR 1.5, Flash Lite 4

underlineOffset 值是距离下划线的罗马字基线的建议垂直偏移。

请注意,为了找出下划线的位置,应该根据行的旋转将此值与行位置相加,或从行位置中减去此值。在具有 TextRotation.ROTATE_0 的行中,underline.y = line.y + underlineOffset。在具有 TextRotation.ROTATE_90 的行中,underline.x = line.x - underlineOffset

将装饰(例如下划线)应用于 TextLine 时,建议的方法是在要接收装饰的 ContentElement 上指定 eventMirror。作为对 Event.ADDED 事件的响应,TextLineMirrorRegionbounds 可与 underlineOffset 结合使用以放置删除线。

相关 API 元素

underlineThickness

属性 
public var underlineThickness:Number

语言版本: ActionScript 3.0
运行时版本: Flash Player 10, AIR 1.5, Flash Lite 4

underlineThickness 值是建议的下划线粗细。

构造函数详细信息

FontMetrics

()构造函数
public function FontMetrics(emBox:Rectangle, strikethroughOffset:Number, strikethroughThickness:Number, underlineOffset:Number, underlineThickness:Number, subscriptOffset:Number, subscriptScale:Number, superscriptOffset:Number, superscriptScale:Number, lineGap:Number = 0.0)

语言版本: ActionScript 3.0
运行时版本: Flash Player 10, AIR 1.5, Flash Lite 4

[ X ]为什么显示为英语?
《ActionScript 3.0 参考》中的内容以英语显示

《ActionScript 3.0 参考》中的部分内容未翻译成所有语言。当某个语言元素未翻译时,将显示为英语。例如,ga.controls.HelpBox 类未翻译成任何语言。因此在简体中文版的参考中,ga.controls.HelpBox 类显示为英语。
