mediaLib Library Functions mlib_ImageColorYCC2RGB_Fp(3MLIB)
NAME
mlib_ImageColorYCC2RGB_Fp - YCC to RGB color conversion
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
mlib_status mlib_ImageColorYCC2RGB_Fp(mlib_image *dst,
const mlib_image *src);
DESCRIPTION
The mlib_ImageColorYCC2RGB_Fp() function performs a color
space conversion from ITU-R Rec.601 Y'CbCr to computer
R'G'B'.The source and destination images must be three-channel
images. It uses the following equation: |R'| |cmat[0] cmat[1] cmat[2]| |Y'| |offset[0]| |G'| = |cmat[3] cmat[4] cmat[5]| * |Cb| + |offset[1]| |B'| |cmat[6] cmat[7] cmat[8]| |Cr| |offset[2]| where cmat[] = { 298.082/256, 0.000/256, 408.583/256,298.082/256, -100.291/256, -208.120/256,
298.082/256, 516.411/256, 0.000/256 };offset[] = { -222.922, 135.575, -276.836 };
src[x][y] = { Y', Cb, Cr }; 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.
