17 The mlib_ImageCopyMask_Fp() function copies one image to another image
18 via a mask image by using it as a yes/no indicator. The data type of
19 the images can be MLIB_FLOAT or MLIB_DOUBLE.
20
21
22 It uses the following equation:
23
24 dst[x][y][i] = src[x][y][i] if mask[x][y][i] ≤ thresh[i]
25 dst[x][y][i] = dst[x][y][i] if mask[x][y][i] > thresh[i]

29 The function takes the following arguments:
30
31 dst Pointer to destination image.
32
33
34 src Pointer to source image.
35
36
37 mask Pointer to mask image.
38
39
40 thresh Threshold for the mask image. thresh[i] contains the thresh‐
41 old for channel i.

45 The function returns MLIB_SUCCESS if successful. Otherwise it returns
46 MLIB_FAILURE.
