Hi,
This is really, really just a guess...
Maybe it's related to the GeoTiffPPIO class inside org.geoserver.wps.ppio.
You can check this class in WPS src.
Look at "encode" method, which receives an Object (GridCoverage2D) and an
OutputStream and writes the GeoTiff to this OutputStream.
I don't know the details of the parameters used to write the image, but
maybe it's somewhere to start.
Regards,
Rodrigo C. Antonialli
