mediaLib Library Functions mlib_ImageScalarBlend_Fp_Inp(3MLIB)
NAME
mlib_ImageScalarBlend_Fp_Inp - image blending with scalar
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
mlib_status mlib_ImageScalarBlend_Fp_Inp(mlib_image *src1dst,
const mlib_image *src2, const mlib_d64 *alpha);
DESCRIPTION
The mlib_ImageScalarBlend_Fp_Inp() function blends the first
and second floating-point 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 isinverse 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 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.
