gammaToLinear method

void gammaToLinear (Vector4 gammaColor, Vector4 linearColor, [ double gamma = 2.2 ])

Convert gammaColor from gamma space into linear color space and store the result in linearColor. It is possible to specify a optional gamma, the default value is 2.2.

Implementation

static void gammaToLinear(Vector4 gammaColor, Vector4 linearColor,
    [double gamma = 2.2]) {
  linearColor
    ..r = math.pow(gammaColor.r, gamma).toDouble()
    ..g = math.pow(gammaColor.g, gamma).toDouble()
    ..b = math.pow(gammaColor.b, gamma).toDouble()
    ..a = gammaColor.a;
}
