Dear list members,

when using tiffcp to decompress lzw-tiffs,
the tags
TIFFTAG_XMLPACKET,
TIFFTAG_RICHTIFFIPTC,
TIFFTAG_PHOTOSHOP
and
TIFFTAG_EXIFIFD (including contents of EXIFIFD)
are not copied.

For the first 3 ones I've added this lines to tools/tiffcp.c: diff -r b39624c02bfb -r 72eecadbc278 tools/tiffcp.c

Is this something which could be added to tiffcp permanently?

Kind regards,
Jochen
