I understand. You dont' use a constructor where SampleDimension are 
explicitly provided, but use instead a convenience constructor that 
compute it automatically. Then you are right, this constructor do not 
provides anyway to control the view (since it is just a convenience 
constructor) and hints could be a way to control that.

I will looks at yours code today and implement it in GridCoverage2D.

I wonder if rescaling a RenderedImage in the convenience constructor for 
any type other than Float and Double is not generally wrong. Maybe we 
should change the GridCoverage2D convenience constructor in order to 
rescale only float and double types, and lets all other types unchanged 
unless a hint is provided?
