Hi,

I think the error message is misleading. I don't think this has anything to
do with 
LuraWave, which is a commercial optimised j2k implementation.

There are two types of JPEG-2000 files. 

1. Minimalistic code streams or .j2k files.

2. An extended format with additional header information (usually saved as
.jp2 files)

The current implementation saves only the code streams  (.j2k files).

The current implementation could be enhanced to support the additional
format, if anyone 
needs this capability. We only need codestreams, so that's all I've
implemented for now.

Regards,
Steve.
