17 The mlib_ImageAve() function computes the average of two images on a
18 pixel-by-pixel basis.
19
20
21 It uses the following equation:
22
23 dst[x][y][i] = (src1[x][y][i] + src2[x][y][i] + 1) / 2
24
25
27 The function takes the following arguments:
28
29 dst Pointer to destination image.
30
31
32 src1 Pointer to first source image.
33
34
35 src2 Pointer to second source image.

39 The function returns MLIB_SUCCESS if successful. Otherwise it returns
40 MLIB_FAILURE.
