Why would the developers of Gimp want to offer LZW compression as an option in the save as tiff dialog of said application? When you try to select this it just whines about a patent issue and then the save fails. It seems to me that it would be far better to just not offer the option, or only offer the option when it can be fulfilled. Let’s hope that they’ll fix this in an upcoming release, it doesn’t seem like it would be much work for somebody alreay familiar with the code base.
