Hi Tore,
the GridCoverageRenderer "renders", that is, paints a map, if you want to
keep on using the raw values,
I'm not aware of anything that will put them for you in a BufferedImage.
But I don't understand why you'd want to do that in the first place, just
get the renderer image out
of the grid coverage and use it as is?
Do you need to reproject it? If so look at the CoverageProcessor, the
resample2d operation in particular.
Cheers
Andrea
