Parameters

  • _string:String ____ Specifies the text.
  • radius:int=180 ____ Specifies the radius of the arch whether it is a full arch (360) or a half arch (180). Default is 180.
  • _textSpace:int=2 ____ Specifies the space between letters. Default is 0.
  • fontsSize:int=12 ____ Specifies the letter size. Default is 12.

  • myFont:String="Verdana" ____ Specifies the font. Default is Verdana.
Examples
Create a new fla file and name it CurveText.fla. Place the fla in the same folder as the biz folder. Put one TextInput component and two NumericStepper components on the stage, name them according to the script. Then create an Actionscript file, name it Curvetext.as and place this script.
