I have a requirement to be able to "copy and paste" a chart from my
flex app to another application via the clipboard. The chart has to
come exactly as it appears on the screen, almost like an
alt-printscreen, but only the portion of the screen displaying the
chart.

Has anyone tried anything like this?

I spotted a display object method called cacheAsBitmap which seems to
be an optimisation for rendering, but I wondered if it was possible to
get access to the display bitmap.

Any clues?
