#include <mlib.h>
mlib_status mlib_ImageColorXYZ2RGB_Fp(mlib_image *dst,
const mlib_image *src);
DESCRIPTION
The mlib_ImageColorXYZ2RGB_Fp() function performs a color space conver‐
sion 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.
