`GammaGray (GammaGrayMap)`
	6.5.2. Subclasses

Name

GammaGray (GammaGrayMap) — gray = x^(1/gamma)

Synopsis

GammaGrayMap(gamma)

Details

Base class: ColorMap
Parameters:

gamma

gamma correction Type: A real number.

Description

ColorMaps translate numbers into colors, for use in contour plots. GammaGray maps low values to black and high values to white, going through all the gray values in between. It's like the GrayMap with gamma correction.

When using GammaGray, the data is scaled to lie between 0 and 1. The gray value of a scaled datum $x$ is $x^{1/\gamma}$ , where $\gamma$ is given by the parameter gamma.
