NAME
       mlib_VideoColorRGBXint_to_ABGRint - convert RGBX interleaved to ABGR interleaved

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

       void mlib_VideoColorRGBXint_to_ABGRint(mlib_u32 *ABGR,
	    const mlib_u32 *RGBX, 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 interleaved RGBX stream and the alpha values are combined into an interleaved A, B, G, R output stream. Within each 32-bit input pixel,
       the component ordering is R (bits 31-24), G (bits 23-16), and B (bits 15-8). Within each 32-bit output pixel, the component bordering is  A
       (bits 31-24), B (bits 23-16), G (bits 15-8), and R (bits 7-0). The alpha values for this function work in the following fashion: if A_array
       is not NULL, the values are taken from the corresponding locations in the alpha array, otherwise  a  constant  alpha  value,  specified	by
       A_const, is store in each output pixel. Each element in the alpha array is an unsigned byte. w and h define the dimensions of the region of
       the buffers to be processed. The linebyte parameters are used to advance the data pointers for each of the buffers.

PARAMETERS
       The function takes the following arguments:

       ABGR	  Pointer to output buffer (word-aligned).

       RGBX	  Pointer to input buffer (word-aligned).

       A_array	  Pointer to array of alpha values (byte-aligned).

       A_const	  Constant alpha value (range = 0..255).

       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.
