Hello,

I want to reproject a GridCoverage2D.
My problem is : when the reprojection is processing, I get an exception
because of negative values in my GridCoverage2D. As I don't need them, I
would like to put some 0 instead of negative values, but I can't find any
information on this topic.
I saw in the javadoc that some setDataBlok() methods exist, but I can't
understand how do they work and if it was what I was searching for...
Somebody can give me an idea or a piece of code ?

Thanks,
Thomas
