Text arcing with Actionscript

I have a project that needs to take dynamic text and arc it. Similar to this:
http://www.no-refresh.com/button_designer/
In this example, select a font then click “create text item”. At this point you can slide the meter to change the arc of the text. This is exactly what I need to do.

My understanding of what needs to be done is I need to first break the letters of the text field into separate text fields, loop thru them then position and rotate each char to the desired arc. The problem is my trigonometry really bites. I’ve tried many tutorials and I’ve gotten similar results, mainly arcing text into a complete circle at different radiuses. But all I need to do is what’s in the example, which is allowing the user to gradually arch the text.

Please any help would be appreciated.

Please I know this is a difficult one but if anybody can help.

here is what I've been experimenting with:

//this would be the input text from the user
//normally I would replace this with the split version
removeEventListener(Event.ADDED_TO_STAGE, init);
var tField:TextField = new TextField()
tField.text = "The world is mine"
tField.border = true
tField.x = 100
tField.y = 100
tField.width = 150
tField.height =20
var myFmt = new TextFormat()
myFmt.size = 18
//myFmt.autoSize = true
tField.setTextFormat(myFmt)
addChild(tField)

var arr:Array = tField.text.split("")
var arc = 45/360//arr.length
var alpha = 0
var xCenter = tField.x + tField.width / 2
var yCenter = tField.y + tField.height/2
for (var i:int = 0; i < arr.length; i++)
{
var t:TextField = new TextField()
t.x = xCenter + 150 * Math.cos(alpha)
t.y = yCenter + 150 * Math.sin(alpha)
t.text = arr[i]
addChild(t)
alpha += arc
}

Our own cancerinform has a tutorial for making curved text using the new flash 10 features:

Thanks this is exactly what I needed.
