Interface: LuminosityUtil

The LuminosityUtil Interface exposes a method for calculating the luminosity using the given R, G, and B components:

Methods:

<float>LuminosityUtil.illumination <float>r <float>g <float>b      

Returns the illumination based on the supplied Red, Green and Blue values.

Note that the contribution of the Red, Green and Blue channels is not identical:

EXAMPLE:

   LuminosityUtil.illumination 255 255 255
   255.0
   LuminosityUtil.illumination 255 0 0
   67.575
