mlib_ImageScalarBlend_Inp(mediaLib Library Funmlib_ImageScalarBlend_Inp(3MLIB)NAMEmlib_ImageScalarBlend_Inp - image blending with scalar, in place
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageScalarBlend_Inp(mlib_image *src1dst,
const mlib_image *src2, const mlib_s32 *alpha);
DESCRIPTION
The mlib_ImageScalarBlend_Inp() function blends the first and second
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 *
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.
