NAME
       mlib_ImageBlendRGBA2BGRA - image blending and channel reordering

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

       mlib_status mlib_ImageBlendRGBA2BGRA(mlib_image *dst,
	    const mlib_image *src);

DESCRIPTION
       The mlib_ImageBlendRGBA2BGRA() function blends the source image of the RGBA format into the destination image of the BGRA format.

       The image type must be MLIB_BYTE. The source and destination images must contain four channels.

       It uses the following equation:

	 Cd = Cs*As + Cd*(1 - As)
	 Ad = Ad

       where,  Cs  and	Cd are the RGB color components of the source and destination images, respectively.  As and Ad are the alpha components of
       the source and destination images, respectively.

PARAMETERS
       The function takes the following arguments:

       dst    Pointer to destination image.

       src    Pointer to source image.

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