Hi Everyone,
For anyone who has been missing the -z option of ra_tiff, which used to
generate LZW output, it is working again in the latest release, or
should have been. The issue surrounded the infamous Unisys patent on
LZW compression, which expired a couple of years ago. The 3.6 release
was _supposed_ to have the new TIFF library with -z enabled again, but
due to pilot error (mine), it never got in there.
To get the latest version, you'll need to download and recompile the
overlay for 3.6 that's on the Radiance websites:
http://radsite.lbl.gov/radiance/download.html
and
http://www.radiance-online.org/software/
Look for the file "rad3R6P1supp.tar.gz".
If you don't know what ra_tiff is or have never used and don't intend
to use this option, then feel free to ignore this message.
-Greg
