The pixels that are set as a result are different, but the underlying circle data is either unchanged, and a transformation matrix is changed, or the circle data itself is transformed (the radius is changed, but the centre remains unchanged). The real (underlying) circle is an abstraction stored as - I would guess - a centre and radius, plus no doubt colour, style and so on. Didn't Plato say something about the world being an imperfect rendering? :-) -- You received this message because you are subscribed to the Google Groups "Everything List" group.
