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

DESCRIPTION
       The  mlib_ImageBlendRGBA2BGRA() function blends the source image of the

       The image type must be MLIB_BYTE. The  source  and  destination	images

       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 desti‐
       nation 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.
