Ah, but now in IDL 5.5 What's New:

IDL 5.5 GIF/TIFF LZW Policy
RSI is pleased to announce the availability of GIF/TIFF LZW support in IDL
5.5. In order to enable this support, IDL users must sign and fax a copy of
the "Proof of Unisys Licensing" release form to RSI. This form states that
the IDL user has a license from Unisys Corporation for use of their patented
technology.

... and from http://www.rsinc.com/idl/UnisysLicense.pdf ...
=====
Proof of Unisys Licensing � for customers requesting the IDL GIF/TIFF LZW
feature
WARNING!
Use of IDL software for providing GIF/TIFF LZW capability for any purpose is
not authorized unless user first enters into a license agreement with Unisys
under U.S. Patent No. 4,558,302 and foreign counterparts.
For information concerning licensing, please contact:

More info on LZW license from Unisys is at:

Seems like a lot of hoops, has anyone actually written to Unisys for such a
license? Do they charge for it?
Cheers,
