NAME
       al_color_rgb_to_cmyk - Allegro 5 API

SYNOPSIS
	      #include <allegro5/allegro_color.h>

	      void al_color_rgb_to_cmyk(float red, float green, float blue,
		 float *cyan, float *magenta, float *yellow, float *key)

DESCRIPTION
       Each  RGB color can be represented in CMYK with a K component of 0 with
       the following formula:

	      C = 1 - R
	      M = 1 - G
	      Y = 1 - B
	      K = 0

       This function will instead find the  representation  with  the  maximal
       value for K and minimal color components.
