>Lossless resizing? How do you envision that?
while I have heard about possible plans about how to do lossless resizing
from one of the JPEG guys, it would require extension of the standard and it
would only be able to resize to 1/8, 2/8, 3/8, ... of the original size.
It does not really make much sense, resizing is destructive by nature and you
usually resize picture to make the file physically smaller, which would not be
possible if it were lossless.
BTW, I am author of a Windows application for lossless rotation, cropping,
canvas extension and retouching called RealWorld Photos.
