The data that I want to see preserved has nothing to do with the image format; it is true metadata that corresponds roughly to IPTC metadata. I guess the specification could observe that anything that qualifies the image encoding must be treated with distrust, however information such as black level, original white point and luminance can be useful even so. -- John Bowler <[email protected]> +1 (541) 450-9885 PO BOX 3151 KERBY OR 97531-3151 USA ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ png-mng-misc mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/png-mng-misc
