SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoColorJFIFYCC2RGB444(mlib_u8 *rgb, const mlib_u8 *y,
const mlib_u8 *cb, const mlib_u8 *cr, mlib_s32 n);
DESCRIPTION
The mlib_VideoColorJFIFYCC2RGB444() function performs color space con‐
version from YCbCr to RGB when used in the JPEG File Interchange Format
(JFIF).
The following equation is used:
R = Y + 1.40200 * (Cr - 128)
G = Y - 0.34414 * (Cb - 128) - 0.71414 * (Cr - 128)
B = Y + 1.77200 * (Cb - 128)
PARAMETERS
The function takes the following arguments:
rgb Pointer to destination RGB multi-component row. rgb must be
8-byte aligned.
y Pointer to source Y component row. y must be 8-byte aligned.
cb Pointer to source Cb component row. cb must be 8-byte aligned.
cr Pointer to source Cr component row. cr must be 8-byte aligned.
n Length of Y component row. The length of Cb and Cr component
rows must be n. The length of the RGB multi-component row must
be 3*n.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
