DESCRIPTION

17       The  mlib_ImageColorHSV2RGB_Fp()  function  performs  a conversion from
18       hue/saturation/value to  red/green/blue.  The  source  and  destination
19       images must be three-channel images.
20
21
22       It uses the following equations:
23
24            P = V*(1 - S)
25            Q = V*(1 - S*fraction(H*6))
26            T = V*(1 - S*(1 - fraction(H*6)))
27
28            R, G, B = V, T, P    if 0   ≤ H < 1/6
29            R, G, B = Q, V, P    if 1/6 ≤ H < 2/6
30            R, G, B = P, V, T    if 2/6 ≤ H < 3/6
31            R, G, B = P, Q, V    if 3/6 ≤ H < 4/6
32            R, G, B = T, P, V    if 4/6 ≤ H < 5/6
33            R, G, B = V, P, Q    if 5/6 ≤ H < 1
34
35
36
37       where 0 ≤ H < 1 and 0 ≤ S, V, P, Q, T, R, G, B ≤ 1.
38
39
40       For MLIB_FLOAT and MLIB_DOUBLE images, the above equations are followed
41       verbatim. Input H component values must be limited to  the  [0.0,  1.0)
42       range. Input S and V component values must be limited to the [0.0, 1.0]
43       range.
44

PARAMETERS

46       The function takes the following arguments:
47
48       dst    Pointer to destination image.
49
50
51       src    Pointer to source image.
52
53

RETURN VALUES

55       The function returns MLIB_SUCCESS if successful. Otherwise  it  returns
56       MLIB_FAILURE.
