[Geotools-gt2-users] FloatRasterDemo Geotools 2.1.0

[Philip M. <pwm...@ya...>]

I am new to Geotools, I was trying to understand the
API by getting the FloatRasterDemo to work.  I
understand that this was a demo for an older Geotools
so I rewrote the code using the new API.

Unfortunately, the result of the code was not what I
expected.  Both the grayscale and colored coverage
appear exactly the same.  Could someone offer me a
hand?

I have attached the new source code.
