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?
