17 The mlib_ImageThresh2_Fp_Inp() function compares each pixel in the
18 floating-point source image to a threshold value, in place. If the
19 pixel is less than or equal to the threshold value, then the destina‐
20 tion pixel is set to the low output level. If the pixel is greater than
21 the threshold value, then the destination pixel is set to the value of
22 the source pixel.

25 It uses the following equation:
26
27 srcdst[x][y][i] = glow[i] if srcdst[x][y][i] ≤ thresh[i]
28

31 The function takes the following arguments:
32
33 srcdst Pointer to source and destination image.
34
35
36 thresh Threshold value. thresh[i] contains the threshold for channel
37 i.
38
39
40 glow Low output level. glow[i] contains the low output level for
41 channel i.

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