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

DESCRIPTION

18       Convert color values between the HSV and RGB color spaces. The RGB val‐
19       ues range from 0 to 255, hue is from 0 to 360, and saturation and value
20       are from 0 to 1. Example:
21
22          int r, g, b;
23          float hue, saturation, value;
24          ...
25          /* Convert a reddish color to HSV format. */
26          rgb_to_hsv(255, 0, 128, &hue, &saturation, &value);
27
28          /* Now put our tin foil hat, and verify that. */
29          hsv_to_rgb(hue, saturation, value, &r, &g, &b);
30          ASSERT(r == 255);
31          ASSERT(g == 0);
32          ASSERT(b == 128);
