IMB_colormanagement_get_luminance()

float IMB_colormanagement_get_luminance

(

const float

rgb[3]

)

Convert a float RGB triplet to the correct luminance weighted average.

Gray-scale, or Luma is a distillation of RGB data values down to a weighted average based on the luminance positions of the red, green, and blue primaries. Given that the internal reference space may be arbitrarily set, any effort to glean the luminance coefficients must be aware of the reference space primaries.
