Hai Mike,
Check this statement.
var bitmap : BitmapData = new BitmapData
( target.width,target.height );
check whether ur receiving component has initialized or not and also
check the target WIDTH and HEIGHT,
if the component height n width is zero the u'll get this error :
ArgumentError: Error #2015: invalid BitmapData. at
flash.display::BitmapData().
Thanks,
Regards,
RIA
