Specifies the type of baseline in the containing element to which to align the dominant baselines of elements having this format. Use TextBaseline constants for this property.

The largest vertical element in the line determines the alignment of baselines unless TextBlock.baselineFontDescription and TextBlock.baselineFontSize are set to override that logic.

The default value is TextBaseline.USE_DOMINANT_BASELINE.

To set values for this property, use the following string values:

See also

Specifies the transparency of the line elements affected by this obect. Valid values range from 0 (fully transparent) to 1 (fully opaque). Display objects with alpha set to 0 are active, even though they are invisible.

The default value is 1.

See also

Indicates the baseline shift for the element in pixels.

The element is shifted away from the dominantBaseline by this amount. The offset is added to the y position of the members of the element, so in non-rotated text, a positive baseline shift moves the element down and a negative baseline shift moves the element up.

The default value is 0.0, indicating no shift.

The line break opportunity applied to this text. This property determines which characters can be used for breaking when wrapping text is broken into multiple lines. Use BreakOpportunity constants for this property.

The default value is BreakOpportunity.AUTO.

To set values for this property, use the following string values:

See also

Indicates the color of the text. An integer containing three 8-bit RGB components; for example, 0xFF0000 is red and 0x00FF00 is green.

The default value is 0x000000, which is black.

The digit case used for this text. Digit case affects the style and positioning of groups of numeric characters. Use DigitCase constants for this property.

The default value is DigitCase.DEFAULT.

To set values for this property, use the following string values:

See also

The digit width used for this text. Use DigitWidth constants for this property.

The default value is DigitWidth.DEFAULT.

To set values for this property, use the following string values:

See also

Specifies the type of baseline to use as the dominant baseline. The dominant baseline is aligned with the alignment baseline to determine the vertical position of the element on the line. Use TextBaseline constants for this property.

The content of the element determines the baselines. In the case of a TextElement, the font and the point size determine the baselines. In the case of a GraphicElement, the height of the element determines the baselines.

The default value is TextBaseline.ROMAN.

To set values for this property, use the following string values:

See also

An object whose properties describe a font.

The default value is a default-constructed FontDescription object.

When the fontDescription property is set, the FontDescription object provided is locked: its locked property is set to true. A locked FontDescription cannot be modified.

See also

The size of text in pixels.

The default value is 12.0.

Kerning adjusts the pixels between certain character pairs to improve readability. Kerning is supported for all fonts which have kerning tables.

The default value is Kerning.ON.

To set values for this property, use the following constants in the Kerning class:

See also

The ligature level used for this text. A ligature occurs where two or more letter-forms are joined as a single glyph. Ligatures usually replace consecutive characters sharing common components, such as the letter pairs 'fi', 'fl', or 'ae'. They are used with both Latin and non-Latin character sets. Use LigatureLevel constants for this property.

The default value is LigatureLevel.COMMON.

To set values for this property, use the following string values:

See also

The locale of the text. Controls case transformations and shaping. Standard locale identifiers are used. For example "en", "en_US" and "en-US" are all English, "ja" is Japanese. See iso639-2 code list for a list of locale codes.

The default value is "en".

Indicates whether the ElementFormat is locked. If true the ElementFormat cannot be modified. Call ElementFormat.clone() to get an unlocked copy of the ElementFormat object.

Sets the rotation applied to individual glyphs. Use constants defined in the TextRotation class for this property.

The default value is TextRotation.AUTO.

The final rotation of any glyph is the sum of ElementFormat.textRotation, ContentElement.textRotation, and TextBlock.lineRotation.

You typically use this property for Asian text where characters must be rotated to display properly in vertical layout. Use TextRotation.AUTO in combination with TextBlock.lineRotation = TextRotation.ROTATE_90 to accomplish this.

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:

See also

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.

Example:

          //positive tracking added to kerning
          var ef1:ElementFormat = new ElementFormat();
          ef1.kerning = flash.text.engine.Kerning.ON;
          ef1.trackingLeft = 0.5;
     
          //negative manual kerning
          var ef2:ElementFormat = new ElementFormat();
          ef2.kerning = flash.text.engine.Kerning.OFF;
          ef2.trackingLeft = -1.0;
     

The tracking or manual kerning applied to the right of each glyph in pixels. If kerning 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. 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.

Example:

          //positive tracking added to kerning
          var ef1:ElementFormat = new ElementFormat();
          ef1.kerning = flash.text.engine.Kerning.ON;
          ef1.trackingRight = 0.5;
     
          //negative manual kerning
          var ef2:ElementFormat = new ElementFormat();
          ef2.kerning = flash.text.engine.Kerning.OFF;
          ef2.trackingRight = -1.0;
     

The typographic case used for this text. Use constants defined in the TypographicCase class for this property.

The default value is TypographicCase.DEFAULT.

To set values for this property, use the following string values:

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.
