In retrospect, it seems reasonable that one would need to use a drawXxx()
command to have
beginBitmapFill() affect the graphics port. Anyway, in case this useful to
anyone else, here's a method
that draws a string to a graphics object:
public function drawString(g:Graphics, str:String, x:Number,
y:Number):void
{
var tf:TextField = new TextField();
tf.text = str;
var bmd:BitmapData = new BitmapData(tf.textWidth + 6,
tf.textHeight, true, 0xFFFFFF);
bmd.draw(tf);
var matrix:Matrix = new Matrix();
matrix.createBox(1, 1, 0, x, y);
g.beginBitmapFill(bmd, matrix);
g.drawRect(x, y, bmd.width, bmd.height);
g.endFill();
}
Of course, in actual use, one would probably want to set fonts, colors, etc.
