The code I posted was just a simple little example of how you could
create a 'raw' container that has no layout capabilities, and can accept
any DisplayObject. You could do it either like this:
<RawContainer>
<SomeFlashSprite />
<SomeBitmap />
</RawContainer>
Or...
<RawContainer id="rc" />
var bmp:Bitmap = new Bitmap();
// get some content into the bitmap.
rc.content = [bmp];

Subject: [flexcoders] Re: copying bitmap data
It is interesting that I would get 4 replies, 4 completely different
answers. My entire week is going this way. As is my Flex project.
So my choices were:
1. Try the Grant Skinner blog and his DisplayObjectWrapper. Not
exactly sure how this works or how to use it within my code.
2. Add .clone to my existing syntax, which I tried without luck
3. Have an image load an image and then copy that - interesting, yet I
have a canvas loaded with many bitmaps and need to make a bitmap of
the canvas ??
4. And finally, from Ely, and extension of the UIComponent class. I'm
sure this is something, but I'm not sure how to use it.
I really appreciate the helpful spirit on this message board. My own
green-ness with Flex is part of the problem, but I thought for sure my
original direction would work since I pulled it almost directly from
the Flex docs.
Here's the code from Flex Docs:
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.text.TextField;
var tf:TextField = new TextField();
tf.text = "bitmap text";
var myBitmapData:BitmapData = new BitmapData(80, 20);
myBitmapData.draw(tf);
var bmp:Bitmap = new Bitmap(myBitmapData);
this.addChild(bmp);
They are copying a TextField rather than a canvas. Is that the issue?
OK to turn a TextField into a bitmap, but not a canvas?
