mediaLib Library Functions          mlib_ImageColorXYZ2RGB(3MLIB)



NAME
     mlib_ImageColorXYZ2RGB - XYZ to RGB color conversion

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

     mlib_status mlib_ImageColorXYZ2RGB(mlib_image *dst, const mlib_image *src);


DESCRIPTION
     The mlib_ImageColorXYZ2RGB() function performs a color space
     conversion  from CIE XYZ to ITU-R Rec.708 RGB with D64 white
     point.


     The source and  destination  images  must  be  three-channel
     images.


     It uses the following equation:

       |R|   |cmat[0] cmat[1] cmat[2]|   |X|
       |G| = |cmat[3] cmat[4] cmat[5]| * |Y|
       |B|   |cmat[6] cmat[7] cmat[8]|   |Z|



     where

       cmat[] = { 3.240479, -1.537150, -0.498535,
                 -0.969256,  1.875992,  0.041566,
                  0.055648, -0.204043,  1.057311 };
       src[x][y] = { X, Y, Z };
       dst[x][y] = { R, G, B };


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.
