So, it turns out to be quite complicated to re-factor the wavelet transform
to only transform a sub-region
inside a single tile image.
I've got it working now for lossy decode, lossless decode also works but 4
units tests are broken at the moment.
And, I am seeing a massive increase in performanc

I see. So, this is repeatable every time you run the test suite? And you
can't reproduce
with opj_compress followed by opj_decompre

Apparently it doesn't like to see "typedef struct foo { ... } bar"
(openjpeg.h) and "typedef struct foo bar" (reg
Hi Even,
Thanks so much for testing this.

Dear GDAL users,
As I've mentioned previously, there are big changes coming to the OpenJPEG
library. Performance is going up and memory usage is going down, by
significant amounts.
To do all of this, we have had to make significant changes to the core of
the library. So, even though all of our un
