17 The mlib_ImageSub() function subtracts the second source image from the
18 first source image on a 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]

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.
