FWIW the following is from http://www.jpg.com/products/wizard.html It implies that normally you would introduce artifacts when doing a mirror and re-saving, but I think is claiming that with this technology you won't degrade the image at all.
My guess is that it does have to clip to nearest 8 x 8 pixel block to do this because the boundaries of these blocks would have to change following a mirror, but this could be wrong. Julian RECOMPRESSION WITHOUT LOSS!* Recompress your JPEG files again and again without introducing generational image loss normally associated with recompressing JPEG files! Because of the underlying Pegasus technology, you can recompress, rotate or mirror JPEG images without introducing recompression artifacts! ---------------------------------------------------------------------------------------- Unsubscribe by mail to [EMAIL PROTECTED], with 'unsubscribe filmscanners' or 'unsubscribe filmscanners_digest' (as appropriate) in the message title or body
