NAME
       mlib_VideoColorJFIFYCC2ARGB444 - JFIF YCbCr to ARGB color conversion

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

       mlib_status mlib_VideoColorJFIFYCC2ARGB444(mlib_u8 *argb,
	    const mlib_u8 *y, const mlib_u8 *cb,
	    const mlib_u8 *cr, mlib_s32 n);

DESCRIPTION
       The  mlib_VideoColorJFIFYCC2ARGB444()  function	performs  color space conversion from YCbCr to ARGB when used in the JPEG File Interchange
       Format (JFIF).

       The following equation is used:

	 A = 0xFF
	 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:

       argb    Pointer to destination ARGB multi-component row. argb 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 ARGB  multi-component  row  must	be
	       4*n.

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