17 The mlib_ImageScalarBlend_Fp() function blends the first and second
18 floating-point source images by adding each of their scaled pixels. The
19 first source image is scaled by the scalar a, and the second source
20 image is inverse scaled by (1 - a).
21
22
23 It uses the following equation:
24
25 dst[x][y][i] = a[i]*src1[x][y][i] + (1 - a[i])*src2[x][y][i]
26
27
29 The function takes the following arguments:
30
31 dst Pointer to destination image.
32
33
34 src1 Pointer to first source image.
35
36
37 src2 Pointer to second source image.
38
39
40 alpha Scalar blending factor. The a value equals alpha which should
41 be in the [0.0, 1.0] range. alpha[i] contains the blending
42 factor for channel i.

44
46 The function returns MLIB_SUCCESS if successful. Otherwise it returns
47 MLIB_FAILURE.
