SYNOPSIS

9       cc [ flag... ] file... -lmlib [ library... ]
10       #include <mlib.h>
11
12       mlib_status mlib_ImageThresh2_Fp_Inp(mlib_image *srcdst,
13            const mlib_d64 *thresh, const mlib_d64 *glow);

DESCRIPTION

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.
23
24
25       It uses the following equation:
26
27         srcdst[x][y][i] = glow[i]  if srcdst[x][y][i] ≤ thresh[i]

PARAMETERS

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.

43

RETURN VALUES

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