Inheritance | ElementFormat Object |
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
ContentElement
. Use the ElementFormat class
to create specific text formatting for the various subclasses of ContentElement. The properties of the ElementFormat class apply to device and
embedded fonts.
An ElementFormat object is applied to a ContentElement in a TextBlock does not invalidate the TextBlock.
Once an ElementFormat has been
applied to an ContentElement, its locked
property is set to true
.
The properties of a locked ElementFormat object cannot be changed. Instead, use the clone()
method to create an unlocked copy of the object, which can be modified and assigned to the ContentElement.

textRotation | property |
textRotation:String
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Sets the rotation applied to individual glyphs. Use flash.text.engine.TextRotation
constants for this property.
The default value is flash.text.engine.TextRotation.AUTO
.
The final rotation of any glyph is the sum of ElementFormat.textRotation
, ContentElement.textRotation
, and TextBlock.lineRotation
.
ElementFormat.textRotation
is used for the typical case of Asian
text where characters must be rotated to display properly in vertical layout,
using the value flash.text.engine.TextRotation.AUTO
combined with TextBlock.lineRotation = flash.text.engine.ROTATE_90
.
Setting this property on fonts which do not contain vertical layout information can give undesirable results. Fonts that contain a vmtx or VORG table, such as the Japanese font "MS Mincho", work correctly because the tables supply the data that the layout engine requires for correct layout. Fonts such as Verdana, which do not contain the necessary information, do not.
To set values for this property, use the following string values:
String value | Description |
---|---|
TextRotation.ROTATE_0 | Glyphs are not rotated. |
TextRotation.ROTATE_90 | Glyphs are rotated 90 degrees clockwise. |
TextRotation.ROTATE_180 | Glyphs are rotated 180 degrees. |
TextRotation.ROTATE_270 | Glyphs are rotated 270 degrees clockwise. |
TextRotation.AUTO | Specifies a 90 degree counter clockwise rotation for full width and wide glyphs only, as determined by the Unicode properties of the glyph. This value is typically used with Asian text to rotate only those glyphs that require rotation. This rotation is applied only in vertical text to return full width and wide characters to a vertical orientation without affecting other characters. |
Subclass | Effect of setting property |
---|---|
GraphicElement | Has no effect. |
GroupElement | Has no effect. |
TextElement | Determines the rotation of the glyphs in the text element. |
Implementation
public function get textRotation():String
public function set textRotation(value:String):void
Throws
ArgumentError — If set to any value which is not a member of flash.text.engine.TextRotation .
| |
IllegalOperationError — If set after the ElementFormat object is locked (locked is true ).

trackingLeft | property |
trackingLeft:Number
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5. |
The tracking or manual kerning applied to the left of each glyph in pixels.
If kerning
is enabled, the trackingLeft
value is added to the values in the
kerning table for the font. If kerning
is disabled, the trackingLeft
value
is used as a manual kerning value. Supports both positive and negative values.
Typically, the desired tracking value is split between trackingRight
and trackingLeft
.
Otherwise, in mixed directionality text, there is twice the tracking at one bidi boundary and none at the other.
The default value is 0.0
.
Subclass | Effect of setting property |
---|---|

is enabled, the trackingRight
value is added to the values in the
kerning table for the font. If kerning
is disabled, the trackingRight
value
is used as a manual kerning value. Supports both positive and negative values.
Typically, the desired tracking value is split between trackingRight
and trackingLeft

clone | () | method |
public function clone():ElementFormat
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Constructs an unlocked, cloned copy of the ElementFormat.
ReturnsElementFormat — An unlocked copy of the ElementFormat object.
|
Example ( How to use this example )
This example creates an ElementFormat
object and sets a FontSize
.
A new TextElement
is created, using the ElementFormat
(and therefore locking it), and
the TextElement
is used as content for a TextBlock
. A
line of text is created from the TextBlock
.
To modify the ElementFormat
object, first check its
locked
property. If true, use the clone()
method to
create an unlocked copy of the ElementFormat
, change its properties,
then re-link the new ElementFormat
to the TextBlock
.
When the lines are re-broken, the new lines will have the new font settings.
package { import flash.display.Sprite; import flash.text.engine.*; public class ElementFormat_cloneExample extends Sprite { private var ef1:ElementFormat; private var ef2:ElementFormat; public function ElementFormat_cloneExample():void { var fd:FontDescription = new FontDescription(); fd.fontLookup = flash.text.engine.FontLookup.DEVICE; fd.fontName = "Palatino"; var ef1:ElementFormat = new ElementFormat(fd); ef1.fontSize=20; var str:String = "This is flash text 0123456789"; var tb:TextBlock = new TextBlock(); var te1:TextElement = new TextElement(str, ef1); tb.content = te1; var line1:TextLine = tb.createTextLine(null, 600); addChild(line1); ef2 = (ef1.locked) ? ef1.clone() : ef1; ef2.fontSize = 32; tb.content.elementFormat=ef2; var line2:TextLine = tb.createTextLine(null, 600); addChild(line2); } } }
getFontMetrics | () | method |
public function getFontMetrics():FontMetrics
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Returns a FontMetrics
object with properties which describe the emBox, strikethrough position,
strikethrough thickness, underline position, and underline thickness for the font specified by
fontDescription
and fontSize
.
FontMetrics — A FontMetrics object describing properties of the font specified by fontDescription .

Example ( How to use this example )
ElementFormat
object with an assigned
FontDescription
and uses the getFontMetrics
method to
display metrics for the chosen font at 24 points.
package { import flash.display.Sprite; import flash.text.engine.*; public class FontMetricsExample extends Sprite { public function FontMetricsExample():void { var fd:FontDescription = new FontDescription(); fd.fontName = "Garamond"; fd.fontWeight = flash.text.engine.FontWeight.BOLD; var ef1:ElementFormat = new ElementFormat(fd); ef1.fontSize = 24; var fm1:FontMetrics = ef1.getFontMetrics(); trace(fm1.emBox); trace(fm1.strikethroughOffset); trace(fm1.strikethroughThickness); trace(fm1.subscriptScale); trace(fm1.subscriptOffset); trace(fm1.superscriptScale); trace(fm1.superscriptOffset); trace(fm1.underlineOffset); trace(fm1.underlineThickness); } } }
This example creates two ElementFormat
objects and sets several of
their properties. It then assigns the new ElementFormats to a TextElement
object,
which has been assigned as the content of a TextBlock
. Note that changing the
ElementFormat
of a TextElement
does not affect TextLines that
have been previously created by the parent TextBlock.
package { import flash.display.Sprite; import flash.text.engine.*; public class ElementFormatExample extends Sprite { public function ElementFormatExample():void { var fd:FontDescription = new FontDescription(); fd.fontName = "Garamond"; fd.fontWeight = flash.text.engine.FontWeight.BOLD; var ef1:ElementFormat = new ElementFormat(fd); ef1.fontSize = 30; ef1.color = 0xFF0000; ef1.alpha = 100; ef1.kerning = flash.text.engine.Kerning.ON; ef1.trackingRight = 2; ef1.typographicCase = flash.text.engine.TypographicCase.UPPERCASE; ef1.alignmentBaseline = flash.text.engine.TextBaseline.DESCENT; ef1.ligatureLevel = flash.text.engine.LigatureLevel.EXOTIC; var ef2:ElementFormat = new ElementFormat(fd); ef2.fontSize = 30; ef2.color = 0xFF0000; ef2.alpha = 0.3; ef2.kerning = flash.text.engine.Kerning.OFF; ef2.typographicCase = flash.text.engine.TypographicCase.LOWERCASE; ef2.digitCase = flash.text.engine.DigitCase.OLD_STYLE; ef2.textRotation = flash.text.engine.TextRotation.ROTATE_180; var str:String = "This is flash text 0123456789"; var tb:TextBlock = new TextBlock(); var te1:TextElement = new TextElement(str, ef1); tb.content = te1; var line1:TextLine = tb.createTextLine(null, 600); addChild(line1); line1.x = 15; line1.y = 30; tb.content.elementFormat = ef2; var line2:TextLine = tb.createTextLine(null, 600); addChild(line2); line2.x = 15; line2.y = 60; } } }
