mlib_ImageScalarBlend - image blending with scalar
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageScalarBlend(mlib_image dst, const mlib_image *src1, const mlib_image *src2, const mlib_s32 *alpha);
DESCRIPTION
The mlib_ImageScalarBlend() function blends the first and second 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 * 2**(-31)). alpha[i] contains the blending factor for channel i.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
