I have deactivated LZW here in CVS:
This requires a full re-compile of GRASS.
1. First, you have to decompress all raster files.
Use the script here:
Perform this job on *all* locations. Ok, it's boring but required.
2. Then re-compile GRASS to activate flate/zlib compression.
3. re-compress all raster maps:
Other option: Use the r.lzw2z written by Eric Miller:
(Eric, please update the web server not to display this file but to
open the "save file" dialog, otherwise only lynx can download it
lynx -source http://www.jps.net/egm2/r.lzw2z.tgz > r.lzw2z.tgz
- a little bit inconvenient for thousand of users interested in r.lzw2z...
Or please rename to r.lzw2z.tar.gz)
r.lzw2z: the data is read/decoded/recoded to a temp file, then reread
and if successful transferred back to the original.
Generally I think it would be o.k. to add it to GRASS since it does the
removal of LZW. But I am not a laywer.
Our motto: Welcome to the patent-free GRASS 5 beta11.
