mediaLib Library Functions mlibImageScalarBlendInp(3MLIB)
NAME
mlibImageScalarBlendInp - image blending with scalar, in
place
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
mlibstatus mlibImageScalarBlendInp(mlibimage *src1dst,
const mlibimage *src2, const mlibs32 *alpha);
DESCRIPTION
The mlibImageScalarBlendInp() function blends the first
and second source images by adding each of their scaled pix-
els 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
* 2**(-31)). alpha[i] contains the blending fac-
tor for channel i.
RETURN VALUES
The function returns MLIBSUCES if successful. Otherwise
it returns MLIBFAILURE.
