Yes, this is what the jpegtran command-line utility does too, which I posted about all those moons ago (Friday). :-) JpegTran can also do lossless cropping and rotation too, although I've not tried it yet. >> 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. There is an option with all utilities which do this to tidy up the 'ragged' pixels that remain as a result of the lossless transformation. ---------------------------------------------------------------------------------------- Unsubscribe by mail to [EMAIL PROTECTED], with 'unsubscribe filmscanners' or 'unsubscribe filmscanners_digest' (as appropriate) in the message title or body
