```auto

[FONT=Courier New]var out:TextFormat = new TextFormat();[/FONT]
[FONT=Courier New]out.font = "Arial";[/FONT]
[FONT=Courier New]out.size = 11;[/FONT]
[FONT=Courier New]out.color = 0xffffff;[/FONT]
 
[FONT=Courier New]var over:TextFormat = new TextFormat();[/FONT]
[FONT=Courier New]over.font = "Arial";[/FONT]
[FONT=Courier New]over.size = 11;[/FONT]
[FONT=Courier New]over.color = 0x000000;[/FONT]
