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. ATTRIBUTES
