17 The mlib_ImageConstDiv() function divides each pixel in an image into a
18 constant value on a pixel-by-pixel basis.
19
20
21 It uses the following equation:
22
23 dst[x][y][i] = c[i] / src[x][y][i]
24
25
26
27 In the case of src[x][y][i] = 0,
28
29 dst[x][y][i] = 0 if c[i] = 0
30 dst[x][y][i] = DATA_TYPE_MAX if c[i] > 0
31 dst[x][y][i] = DATA_TYPE_MIN if c[i] < 0
32
33
34
35 where DATA_TYPE is MLIB_U8, MLIB_S16, MLIB_U16, or MLIB_S32 for an
36 image of type MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT, respec‐
37 tively.
38
40 The function takes the following arguments:
41
42 dst Pointer to destination image.
43
44
45 src Pointer to source image.
46
47
48 c Constant into which each pixel is divided. c[i] contains the
49 constant for channel i.
50
51
53 The function returns MLIB_SUCCESS if successful. Otherwise it returns
54 MLIB_FAILURE.
