Generating Source Info For Flex BitmapData.

Question

Instead of populating the BitmapData class from an IMAGE. I would like to (within Actionscript) GENERATE some new BitmapData by capturing the Bitmap representing say, a TextArea component on the stage.

In other words, sort of take a "screen capture" or "screenshot" of one of the components, and convert that into an image. Am I silly to even wonder if such a thing is feasible? Can an Air/Flex app "look at itself" in this way? Can it turn a datagrid or a canvas or a textinput into the corresponding image AS IF via screen capture?

Even a hint in the right direction would be appreciated,

Thanks In Advance.

If you want to take the screenshot of particular component, then you need to use the BitMapData class and calculate pixel by pixel by drawing it.
