Well, for one thing, the program is a bit up in the air on final
specifications. Sometimes it's running off the network, other times it's
running locally. It's just very handy to move around one single SWF and not
have to drag along all the various logos. It's also handy for the SWF to
have a builtin list of possible logos to use. I admit that part of the
reason is just to see if I could, and therefore to add to the toolbox of
abilities I have.
And I'm pleased to announce that I have succeeded!
There might be a better way to do it, but what I'm doing now is this:
var svg:DisplayObject = new logo;
var bd:BitmapData = new BitmapData(svg.width, svg.height);
bd.draw(svg);
var ba:ByteArray = new PNGEncoder().encode(bd);
for (var i:int = 0; i < testtext.numChildren; i++)
{
var o:DisplayObject = testtext.getChildAt(i);
if (o is UITextField)
{
var r:Loader = UITextField(o).getImageReference("logo") as
Loader;
r.loadBytes(ba);
}
}
There's the minor issue of resizing the svg before converting it to a
bitmap. But I've made some progress on doing that. And I'll probably
subclass Text or some component so I can get at textField without having to
iterate through the children.
Thanks to everyone for their help, and I look forward to hearing any further
suggestions, tips or mockery. ;)
I'll try to write up a more complete example for posterity and post it as a
followup.
