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.
