If I draw a diagonal line in flash and convert it to a symbol, how do I make its width grow to 100% on that angle. I have a map with  I would do it the easy way by tweening a blocker over it but the line is over an image and the blocker would be noticeable.  I will need to make a bunch of these growing lines at various angles.  Here's what I'm working on http://dev.fusionapps.com/wboe/flash/wboe_map_links2.html  The John F. Kennedy link is an example with a tweening blocker and want to replace with code.  I will need to do the same on the rest of the buttons.

Any help would greatly be appreciated and 500 points to the expert with the solution.

This will be for MX, was using Flash 5 for a different project by request.  Might as well kill two birds with one stone, got an additonal question here http://www.experts-exchange.com/Web/WebDevSoftware/Flash/Q_20785183.html  for 500 points as usual.

Does this have anything to do with it, don't understand it completely, guess we need to calculate slope first, found this site:

http://www.kirupa.com/developer/actionscript/backface_culling.htm

Was able to get the code, maybe it can be modified to calculate the angles of drawn lines.:

function ()
{
    return((b._y - a._y) / (b._x - a._x) - (c._y - a._y) / (c._x - a._x) < 0 ^ (a._x < b._x ^ a._x < c._x));
} // End of the function
isVisible = function ();
c.onPress = startDrag;
b.onPress = startDrag;
a.onPress = startDrag;
c.onRelease = stopDrag;
b.onRelease = stopDrag;
a.onRelease = stopDrag;
c.onReleaseOutside = stopDrag;
b.onReleaseOutside = stopDrag;
a.onReleaseOutside = stopDrag;
a.hitArea = a.dot;
b.hitArea = b.dot;
c.hitArea = c.dot;
this.onEnterFrame = function ()
{
    this.clear();
    this.lineStyle(2, 7829367, 100);
    this.moveTo(c._x, c._y);
    if (isVisible())
    {
        this.beginFill(16756655, 100);
    } // end if
    this.lineTo(a._x, a._y);
    this.lineTo(b._x, b._y);
    this.lineTo(c._x, c._y);
    this.endFill();
} // End of the function


Also found this on expert exchange, this is not to clear either to me:

If you need more points, let me know and I'll start a new question.

Your help is unprecedented, thank you.
