Title
Body
I am trying to implement a solution for calculating the conversion between RGB and CMYK and vice versa. Here is what I have so far: public static int[] rgbToCmyk(int red, int green, int blue) { int black = Math.min(Math.min(255 - red, 255 - green), 255 - blue); if (black!=255) { int cyan = (255-red-black)/(255-black); int magenta = (255-green-black)/(255-black); int yellow = (255-blue-black)/(255-black); return new int[] {cyan,magenta,yellow,black}; } else { int cyan = 255 - red; int magenta = 255 - green; int yellow = 255 - blue; return new int[] {cyan,magenta,yellow,black}; } } public static int[] cmykToRgb(int cyan, int magenta, int yellow, int black) { if (black!=255) { int R = ((255-cyan) * (255-black)) / 255; int G = ((255-magenta) * (255-black)) / 255; int B = ((255-yellow) * (255-black)) / 255; return new int[] {R,G,B}; } else { int R = 255 - cyan; int G = 255 - magenta; int B = 255 - yellow; return new int[] {R,G,B}; } }
