NAME
       mlib_VideoColorUYVY422int_to_ABGRint - color convert UYVY interleaved to ABGR interleaved

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

       void mlib_VideoColorUYVY422int_to_ABGRint(mlib_u32 *ABGR,
	    const mlib_u32 *UYVY, const mlib_u8 *A_array,
	    mlib_u8 A_const, mlib_s32 w, mlib_s32 h, mlib_s32 dlb,
	    mlib_s32 slb, mlib_s32 alb);

DESCRIPTION
       The  UYVY pixel stream is converted into an ABGR pixel stream. All pixel components are 8-bit unsigned integers. The UYVY buffer has dimen-
       sions w/2 and h. The ABGR buffer has dimensions w and h. Dimension w is assumed to be even.

       The alpha values for this function work in the following fashion:

	   o	  If A_array pointer is not NULL, the values are taken from there. It has to have the same dimensions as the Y buffer.

	   o	  If A_array pointer is NULL, the alpha values for every pixel are set to A_const.

       The following equation is used:

	 |R|   |1.1644	0.0000	1.5966|   [|Y|	 | 16.0000|]
	 |G| = |1.1644 -0.3920 -0.8132| * [|U| - |128.0000|]
	 |B|   |1.1644	2.0184	0.0000|   [|V|	 |128.0000|]

PARAMETERS
       The function takes the following arguments:

       ABGR	  Pointer to output buffer.

       UYVY	  Pointer to input buffer.

       A_array	  Array of alpha values.

       A_const	  Constant alpha value.

       w	  Image width in pixels.

       h	  Image height in lines.

       dlb	  Linebytes for output buffer.

       slb	  Linebytes for input buffer.

       alb	  Linebytes for alpha buffer.

RETURN VALUES
       None.
