mlib_imagecolorrgb2ycc
mlib_ImageColorRGB2YCC(3MLIB) mediaLib Library Functions mlib_ImageColorRGB2YCC(3MLIB)NAME
mlib_ImageColorRGB2YCC - RGB to YCC color conversion
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageColorRGB2YCC(mlib_image *dst, const mlib_image *src);
DESCRIPTION
The mlib_ImageColorRGB2YCC() function performs a color space conversion from computer R'G'B' to ITU-R Rec.601 Y'CbCr.
The source and destination images must be three-channel images.
It uses the following equation:
|Y'| |cmat[0] cmat[1] cmat[2]| |R'| |offset[0]|
|Cb| = |cmat[3] cmat[4] cmat[5]| * |G'| + |offset[1]|
|Cr| |cmat[6] cmat[7] cmat[8]| |B'| |offset[2]|
where
cmat[] = { 65.738/256, 129.057/256, 25.064/256,
-37.945/256, -74.494/256, 112.439/256,
112.439/256, -94.154/256, -18.285/256 };
offset[] = { 16, 128, 128 };
src[x][y] = { R', G', B' };
dst[x][y] = { Y', Cb, Cr };
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.
