[gdal-dev] New compression library based on gdal design

[Even Rouault]

Aaron,

I'm a bit surprised about your qualifying of the openjpeg code base as 
"spaghetti code". I've not spent a lot of time in it, just fixing a few bugs 
here or there, but this was not my feeling at all. I can't remember having 
seen goto's.

Anyway just seeing that gpu_jpeg2k is licenced under Affero GPL, so if you plan 
to port it, you will also be bound by that licence, which might limit the 
potential audience for your library.

What would be cool is to have GPU accelerated backend in an existing library 
such as OpenJPEG to avoid having to write yet another GDAL JPEG2000 driver. We 
have already 5 of them ! And I think people have started experimented about 
acceleration routines in OpenJPEG so that might be a good idea to exchange on 
their mailing list about what already exists.

Best regards,

Even
