sion
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoColorJFIFYCC2RGB420_Nearest(mlib_u8 *rgb0,
mlib_u8 *rgb1, const mlib_u8 *y0,
const mlib_u8 *y1, const mlib_u8 *cb,
const mlib_u8 *cr, mlib_s32 n);
DESCRIPTION
The mlib_VideoColorJFIFYCC2RGB420_Nearest() function performs color
space conversion from YCbCr to RGB together with sampling rate conver‐
sion when used in the JPEG File Interchange Format (JFIF).
PARAMETERS
The function takes the following arguments:
rgb0 Pointer to upper destination RGB multi-component row. rgb0 must
be 8-byte aligned.
rgb1 Pointer to lower destination RGB multi-component row. rgb1 must
be 8-byte aligned.
y0 Pointer to upper destination Y component row. y0 must be 8-byte
aligned.
y1 Pointer to lower destination Y component row. y1 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. n must be even. The length of Cb and
Cr component rows must be n/2. The length of the RGB multi-com‐
ponent row must be 3*n.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
