mlib_VideoColorBGR2JFIFYCC444_S16(3MLIB)		    mediaLib Library Functions			  mlib_VideoColorBGR2JFIFYCC444_S16(3MLIB)

NAME

       mlib_VideoColorBGR2JFIFYCC444_S16 - BGR to JFIF YCbCr color conversion

SYNOPSIS

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

       mlib_status mlib_VideoColorBGR2JFIFYCC444_S16(mlib_s16 *y, mlib_s16 *cb,
	    mlib_s16 *cr, const mlib_s16 *bgr, mlib_s32 n);

DESCRIPTION

       The  mlib_VideoColorBGR2JFIFYCC444_S16()  function performs color space conversion from BGR to YCbCr when used in the JPEG File Interchange
       Format (JFIF).

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

       The following equation is used:

	 Y  =  0.29900 * R + 0.58700 * G + 0.11400 * B
	 Cb = -0.16874 * R - 0.33126 * G + 0.50000 * B	+ 2048
	 Cr =  0.50000 * R - 0.41869 * G - 0.08131 * B	+ 2048

PARAMETERS

       The function takes the following arguments:

       y      Pointer to destination Y component row. y must be 8-byte aligned.

       cb     Pointer to destination Cb component row. cb must be 8-byte aligned.

       cr     Pointer to destination Cr component row. cr must be 8-byte aligned.

       bgr    Pointer to source BGR multi-component row. bgr 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 BGR multi-component row must be 3*n.

RETURN VALUES

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