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.
