SYNOPSIS

10       #include <mlib.h>

12       mlib_status mlib_ImageThresh2_Fp(mlib_image *dst, const mlib_image *src,
13            const mlib_d64 *thresh, const mlib_d64 *glow);

DESCRIPTION

17       The  mlib_ImageThresh2_Fp()  function compares each pixel in the float‐
18       ing-point source image to a threshold value. If the pixel is less  than
19       or  equal  to the threshold value, then the destination pixel is set to
20       the low output level. If the pixel is greater than the threshold value,
21       then the destination pixel is set to the value of the source pixel.
22
23
24       It uses the following equation:
25
26         dst[x][y][i] = glow[i]       if src[x][y][i] ≤ thresh[i]
27         dst[x][y][i] = src[x][y][i]  if src[x][y][i] > thresh[i]

PARAMETERS

31       The function takes the following arguments:
32
33       dst       Pointer to destination image.
34
35
36       src       Pointer to source image.
37
38
39       thresh    Threshold value. thresh[i] contains the threshold for channel
40                 i.
41
42
43       glow      Low output level. glow[i] contains the low output  level  for
44                 channel i.

RETURN VALUES

48       The  function  returns MLIB_SUCCESS if successful. Otherwise it returns
49       MLIB_FAILURE.
