NAME

mlib_VideoColorJFIFYCC2RGB420_Nearest - JFIF YCbCr to RGB color conversion  

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 conversion 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-component row must be 3*n.

 

RETURN VALUES

The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
