NAME
     mlib_ImageBlendRGBA2BGRA - image blending and channel reord-
     ering

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlib_status mlib_ImageBlendRGBA2BGRA(mlib_image *dst,

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.
