[vtkusers] Tiff LZW compression

[Ken Greiner]

Hi,

I'd like to use LZW compression with the vtkTIFFWriter, but I'm having 
some trouble.  First, there's a licensing check for LZW compression, 
which seems to be out of date (I believe that all relevant LZW 
compression patents have expired?)
When I disable that license check in vtkTIFFWriter.cxx and recompile, I 
get an out-of-disk-space error whenever I try to export a compressed 
TIFF.  I've got lots of disk space, so I assume that this is a failure 
somewhere in the tiff writer ( in fact I can see a generic error trap 
that shows the out-of-disk-space message for any tiff writer failure).
Is there somebody out there who knows the code better than I do and 
could help me sort this out?
Some more misc. information - I'm running on Windows 2K and XP, 
compiling with .NET 2003 and using VTK version 5.0 source code.

Thanks!

Ken
