NAME
       mlib_VideoColorJFIFYCC2RGB444_S16 - JFIF YCbCr to RGB color conversion

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_VideoColorJFIFYCC2RGB444_S16(mlib_s16 *rgb,
	    const mlib_s16 *y, const mlib_s16 *cb,
	    const mlib_s16 *cr, mlib_s32 n);

DESCRIPTION
       The  mlib_VideoColorJFIFYCC2RGB444_S16()  function performs color space conversion from YCbCr to RGB when used in the JPEG File Interchange
       Format (JFIF).

       Both the input YCbCr components and the output RGB components are supposed to be in the range of [0, 4095].

       The following equation is used:

	 R = Y			       + 1.40200 * (Cr - 2048)
	 G = Y - 0.34414 * (Cb - 2048) - 0.71414 * (Cr - 2048)
	 B = Y + 1.77200 * (Cb - 2048)

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.
