Description

On Linux/GTK at least, the default compression (LZW) is
rejected by libtiff due to patent issues.

It would be good to pick a different default, perhaps
PACKBITS, that is not encumbered. It would also help
if the way to choose another compression algorithm were
documented

Hasn't this patent expired a few years ago?

That's not what I read on
 http://www.gnu.org/philosophy/gif.html. You may be right
about the USA patent, but the implication is that there are
others.

I had a look at libtiff ChangeLog. LZW compression code was merged back before 3.7.0 and wx is distributed with 3.8.2, so I suppose the problem is gone.
