You're correct. BitmapData is the information that describes
the pixel data
of a raster image. A Bitmap is the DisplayObject used on the

provides access to
the BitmpData instance which makes up its image, however
instances don't necessarily need to be associated with any
as they can be used in other ways such as with filters.
