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 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. 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.
