Detailed Description

Interface for layers in which a colour scale represents (or can sometimes represent, depending on the display mode) the sample value.

For example, TimeValueLayer uses colour scale when in segment mode and so provides this interface for use by the LogColourScale or LinearColourScale scale renderers.
