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.
