Hi Cristophe,
what do you mean with NativeJaiExt?
I think we can distinguish between 3 cases:
1) native jai: which means you have both medialib native libs and mlib
wrapper jars available on your env.
2) pure jai: no medialib available
3) jai-ext: a jai replacement including support for nodata and ROI.
The latter need a JAVA_OPT property to be activated:
-Dorg.geotools.coverage.jaiext.enabled=true (Then you may select in the
GeoServer GUI -> Settings -> ImageProcessing menu which operations to be
used)
As far as I remember, some medialib operations are bugged. If my memory
serves me well, some of them are dealing with logarithm, division, band
manipulation.The source code of the native implementation isn't available
so there is no chance to fix the bugs. This is also why we started not
using it anymore and also started writing jai-ext operations.
Does it make sense?
Cheers,
Daniele
