SYNOPSIS

10       #include <mlib.h>
11
12       mlib_status mlib_ImageThresh4_Inp(mlib_image *srcdst,
13            const mlib_s32 *thigh, const mlib_s32 *tlow, const mlib_s32 *ghigh,
14            const mlib_s32 *glow);

DESCRIPTION

18       The  mlib_ImageThresh4_Inp() function compares each pixel in the source
19       image to two threshold values, tlow and thigh. If  the  pixel  is  less
20       than the lower threshold value, tlow, then the destination pixel is set
21       to the lower output level, glow. If  the  pixel  is  greater  than  the
22       higher threshold value, thigh, then the destination pixel is set to the
23       higher output level, ghigh. Otherwise, the destination pixel is set  to
24       the value of the source pixel.
25
26
27       It uses the following equation:
28
29         srcdst[x][y][i] = glow[i]   if srcdst[x][y][i] < tlow[i]
30         srcdst[x][y][i] = ghigh[i]  if srcdst[x][y][i] > thigh[i]

PARAMETERS

34       The function takes the following arguments:
35
36       srcdst    Pointer to source and destination image.
37
38
39       thigh     High  threshold  value. thigh[i] holds the high threshold for
40                 channel i.
41
42
43       tlow      Low threshold value. tlow[i]  holds  the  low  threshold  for
44                 channel i.
45
46
47       ghigh     High  output  grayscale level. ghigh[i] holds the high output
48                 grayscale level for channel i.
49
50
51       glow      Low output grayscale level.  glow[i]  holds  the  low  output
52                 grayscale level for channel i.
53
54

RETURN VALUES

56       The  function  returns MLIB_SUCCESS if successful. Otherwise it returns
57       MLIB_FAILURE.
