NAME
       mlib_ImageScalarBlend_Fp - image blending with scalar

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

       mlib_status mlib_ImageScalarBlend_Fp(mlib_image *dst, const mlib_image *src1, const mlib_image *src2, const mlib_d64 *alpha);

DESCRIPTION
       The  mlib_ImageScalarBlend_Fp()	function  blends  the first and second floating-point source images by adding each of their scaled pixels.
       The first source image is scaled by the scalar a, and the second source image is inverse scaled by (1 - a).

       It uses the following equation:

       dst[x][y][i] = a[i]*src1[x][y][i] + (1 - a[i])*src2[x][y][i]

PARAMETERS
       The function takes the following arguments:

       dst	       Pointer to destination image.

       src1	       Pointer to first source image.

       src2	       Pointer to second source image.

       alpha	       Scalar blending factor.	The a value equals alpha which should be in the [0.0, 1.0] range.  alpha[i] contains the  blending
		       factor for channel i.

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