NAME
       mlib_ImageScalarBlend_Fp_Inp - image blending with scalar

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

       mlib_status mlib_ImageScalarBlend_Fp_Inp(mlib_image *src1dst, const mlib_image *src2, const mlib_d64 *alpha);

DESCRIPTION
       The  mlib_ImageScalarBlend_Fp_Inp() function blends the first and second floating-point source images by adding each of their scaled pixels
       in place.  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:

       src1dst[x][y][i] = a[i]*src1dst[x][y][i] +
			  (1 - a[i])*src2[x][y][i]

PARAMETERS
       The function takes the following arguments:

       src1dst	       Pointer to first source and destination 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.
