NAME

mlib_ImageColorRGB2XYZ - RGB to XYZ color conversion  

SYNOPSIS

#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
