mediaLib Library Functions mlib_ImageColorRGB2XYZ(3MLIB)
NAME
mlib_ImageColorRGB2XYZ - RGB to XYZ color conversion
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
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.
