Rearranging information doesn't cause anything to be lost.
However,
sharpening and many other manipulations actually destroy
information;
they do not simply rearrange it.

But you don't know what kind of sharpening to do until you know
the
exact output device you'll be using.<


That's what Qimage (on Windows) does for you, it knows the best
input for a given driver/printer and adapts the
sharpening/extrapolation to that output. The file isn't saved
afterwards so you don't save printer specific data. Reading Bruce
Fraser's article I thought at one third that it had an analogy
with ICC colour management then the next alinea contained the
same
observation. Stretching that idea it would be nice to have a kind
of sharpening preview on while using the other tools. It could be
done with an action but that would affect information loss. It
wouldn't include print sharpening.
