NAME

       hsv_to_rgb,  rgb_to_hsv  -  Converts  color  values  between the HSV and RGB color spaces.
       Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       void hsv_to_rgb(float h, float s, float v, int *r, int *g, int *b);

       void rgb_to_hsv(int r, int g, int b, float *h, float *s, float *v);

DESCRIPTION

       Convert color values between the HSV and RGB color spaces. The RGB values range from 0  to
       255, hue is from 0 to 360, and saturation and value are from 0 to 1. Example:

          int r, g, b;
          float hue, saturation, value;
          ...
          /* Convert a reddish color to HSV format. */
          rgb_to_hsv(255, 0, 128, &hue, &saturation, &value);

          /* Now put our tin foil hat, and verify that. */
          hsv_to_rgb(hue, saturation, value, &r, &g, &b);
          ASSERT(r == 255);
          ASSERT(g == 0);
          ASSERT(b == 128);
