16 The mlib_ImageConstDiv_Inp() function divides each pixel in an image by
17 a constant value on a pixel-by-pixel basis, in place.
18
19
20 It uses the following equation:
21
22 srcdst[x][y][i] = c[i] / srcdst[x][y][i]
23
24
25
26 In the case of srcdst[x][y][i] = 0,
27
28 srcdst[x][y][i] = 0 if c[i] = 0
29 srcdst[x][y][i] = DATA_TYPE_MAX if c[i] > 0
30 srcdst[x][y][i] = DATA_TYPE_MIN if c[i] < 0
31
32
33
34 where DATA_TYPE is MLIB_U8, MLIB_S16, MLIB_U16, or MLIB_S32 for an
35 image of type MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT, respec‐
36 tively.
37
39 The function takes the following arguments:
40
41 srcdst Pointer to source and destination image.
42
43
44 c Constant into which each pixel is divided. c[i] contains the
45 constant for channel i.
46
47
49 The function returns MLIB_SUCCESS if successful. Otherwise it returns
50 MLIB_FAILURE.
