#include <mlib.h>
mlib_status mlib_ImageColorRGB2XYZ(mlib_image *dst, const mlib_image *src);
DESCRIPTION
The mlib_ImageColorRGB2XYZ() function performs a color space conversion
from ITU-R Rec.708 RGB with D64 white point to CIE XYZ.
The source and destination images must be three-channel images.
It uses the following equation:
|X| |cmat[0] cmat[1] cmat[2]| |R|
|Y| = |cmat[3] cmat[4] cmat[5]| * |G|
|Z| |cmat[6] cmat[7] cmat[8]| |B|
where
cmat[] = { 0.412453, 0.357580, 0.180423,
0.212671, 0.715160, 0.072169,
0.019334, 0.119193, 0.950227 };
src[x][y] = { R, G, B };
dst[x][y] = { X, Y, Z };
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.
