17 The mlib_ImageColorXYZ2RGB_Fp() function performs a color space conver‐
18 sion from CIE XYZ to ITU-R Rec.708 RGB with D64 white point.
19
20
21 The source and destination images must be three-channel images.
22
23
24 It uses the following equation:
25
26 |R| |cmat[0] cmat[1] cmat[2]| |X|
27 |G| = |cmat[3] cmat[4] cmat[5]| * |Y|
28 |B| |cmat[6] cmat[7] cmat[8]| |Z|

33
34 cmat[] = { 3.240479, -1.537150, -0.498535,
35 -0.969256, 1.875992, 0.041566,
36 0.055648, -0.204043, 1.057311 };
37 src[x][y] = { X, Y, Z };
38 dst[x][y] = { R, G, B };

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

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