Re: Image Framework In OpenJUMP

But congratulations to Erwan and his team on the georaster library.  I'm very interested to see the results.

The same is true of the ones generated by LizardTech, and I don't believe that their free conversion utility supports Jpeg2000.  The format may end up as unsupportable as TIFF, and for the same reason.

Hi Erwan,

Have you done any experimentation with Jpeg2000, I tried some
experiments with imagemagik on linux and found that it's difficult to
get it to work with the many different flavours of Jpeg200. For example
the samples I had were generated by ermappers codec and it could not
read them.

Cheers,
Paul
