mediaLib Library Functions       mlib_ImageColorHSV2RGB_Fp(3MLIB)



NAME
     mlib_ImageColorHSV2RGB_Fp - HSV to RGB color conversion

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlib_status mlib_ImageColorHSV2RGB_Fp(mlib_image *dst,
          const mlib_image *src);


DESCRIPTION
     The mlib_ImageColorHSV2RGB_Fp() function performs a  conver-
     sion from hue/saturation/value to red/green/blue. The source
     and destination images must be three-channel images.


     It uses the following equations:

          P = V*(1 - S)
          Q = V*(1 - S*fraction(H*6))
          T = V*(1 - S*(1 - fraction(H*6)))

          R, G, B = V, T, P    if 0   < H < 1/6
          R, G, B = Q, V, P    if 1/6 < H < 2/6
          R, G, B = P, V, T    if 2/6 < H < 3/6
          R, G, B = P, Q, V    if 3/6 < H < 4/6
          R, G, B = T, P, V    if 4/6 < H < 5/6
          R, G, B = V, P, Q    if 5/6 < H < 1



     where 0 < H < 1 and 0 < S, V, P, Q, T, R, G, B < 1.


     For MLIB_FLOAT and MLIB_DOUBLE images, the  above  equations
     are followed verbatim. Input H component values must be lim-
     ited to the [0.0, 1.0) range. Input S and V component values
     must be limited to the [0.0, 1.0] range.

PARAMETERS
     The function takes the following arguments:

     dst    Pointer to destination image.


     src    Pointer to source image.


RETURN VALUES
     The function returns MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.
