DESCRIPTION

17       The mlib_ImageColorRGB2XYZ_Fp() function performs a color space conver‐
18       sion from ITU-R Rec.708 RGB with D64 white point to CIE XYZ.
19
20
21       The source and destination images must be three-channel images.
22
23
24       It uses the following equation:
25
26         |X|   |cmat[0] cmat[1] cmat[2]|   |R|
27         |Y| = |cmat[3] cmat[4] cmat[5]| * |G|
28         |Z|   |cmat[6] cmat[7] cmat[8]|   |B|
29
30
31
32       where
33
34         cmat[] = { 0.412453, 0.357580, 0.180423,
35                    0.212671, 0.715160, 0.072169,
36                    0.019334, 0.119193, 0.950227 };
37         src[x][y] = { R, G, B };
38         dst[x][y] = { X, Y, Z };

PARAMETERS

42       The function takes the following arguments:
43
44       dst    Pointer to destination image.
45
46
47       src    Pointer to source image.
48
49

RETURN VALUES

51       The function returns MLIB_SUCCESS if successful. Otherwise  it  returns
52       MLIB_FAILURE.
