Hi Matthias,
Thanks - I suppose QGIS reads J2K files via GDAL ?
My improvements are :
- much faster tile decode (use multiple cores)
- much lower memory usage for decode
- fast sub-tile decode for large single-tile images
Eventually, I would like to enable viewing of files larger than 4 GB, which
is a limitation at the moment with OpenJPEG.
Cheers,
Aaron
