Just wanted to let you know that my new toolkit, renamed Grok,
is available with the following features:
1) Full support for decoding gigapixel images
2) Reduced memory consumption
3) Single image decode performance approximately 1/3 of premiere J2K commercial Kakadu toolkit
It also has fast precinct-level decode for fast decoding of tile sub-regions, but this is currently disabled as I investigate a few valgrind warnings.
You can find the code here:
