C# Class Smrf.GraphicsLib.ColorGradientMapper

Maps a range of color metric values to colors within a gradient.
Call the Initialize() method to specify the color metric range, the color gradient to map the range to, and the number of discrete colors to split the gradient into. You can then call ColorMetricToColor() to map a color metric within the range to one of the discrete colors within the gradient, or ColorMetricToBrush() to get a corresponding brush.

Call Dispose() when you are done using the object.
