colormaps

Drop-in library for nice color maps in C++.

Currently, color maps are from the CET Perceptually Uniform Colour Maps.

Usage

Simply include colormaps.h and use desired color-maps.

Example:

#include <colormaps.h>
using colormaps::rgb_color;                       // just std::array<double, 3>
auto colormap = colormaps::linear::kryw_0_97_c73; // pick color-map

double x = 0.7;                                   // value in [0,1]
rgb_color color = colormap(x);                    // (r,g,b) values in [0,1]^3
