[filmscanners] Re: JPEG Lossless mirror?



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.

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!
