public kerning : Boolean
A Boolean value that indicates whether kerning is enabled or disabled. Kerning puts a predetermined amount of space between certain character pairs to improve readability. The default value is
false, which indicates that kerning is disabled.
Kerning is supported for embedded fonts only. Certain fonts, such as Courier New, do not support kerning.
kerning property is only supported in SWF files created in Windows, not in SWF files created on the Macintosh. However, Windows SWF files can be played in non-Windows versions of Flash Player, and the kerning will still apply.
Use kerning only when necessary, such as with headings in large fonts.
Availability: ActionScript 1.0; Flash Player 8
The following example shows two text fields: The format of the first uses red text with
kerning set to
false, and the format of the second uses blue text with
kerning set to
true. To use this example, you add a font symbol to the Library, and then select Arial as the font. In the Linkage Properties dialog box for the font, you set the Identifier name to
"Font 1", select Export for ActionScript, and then select Export in First Frame.
var fmt1:TextFormat = new TextFormat(); fmt1.font = "Font 1"; fmt1.size = 50; fmt1.color = 0xFF0000; fmt1.kerning = false; var fmt2:TextFormat = new TextFormat(); fmt2.font = "Font 1"; fmt2.size = 50; fmt2.color = 0x0000FF; fmt2.kerning = true; this.createTextField("tf1", this.getNextHighestDepth(), 10, 10, 400, 100); tf1.embedFonts = true; tf1.text = "Text 7AVA-7AVA"; tf1.setTextFormat(fmt1); this.createTextField("tf2", this.getNextHighestDepth(), 10, 40, 400, 100); tf2.embedFonts = true; tf2.text = tf1.text; tf2.setTextFormat(fmt2);
If your SWF file includes a version 2 component, use the version 2 components' DepthManager class instead of the
MovieClip.getNextHighestDepth() method, which is used in this example.
