Analyze /Decode behavior #3

Actually we only tested common Decode arrays with values between 0 and 1 in grayscale images (1bpc) - they map to white or black throughout.

What happens if a RGB image has a Decode array of e.g. this: [0.7 -0.6 1 -1 0 1]?

What's the correct behavior for 16bpc or 32bpc?
