NAME
       mlib_ImageThresh1_Inp - image thresholding

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageThresh1_Inp(mlib_image *srcdst, const mlib_s32 *thresh, const mlib_s32 *ghigh, const mlib_s32 *glow);

DESCRIPTION
       The  mlib_ImageThresh1_Inp()  function  compares  each pixel in the image to a threshold value on a per-channel basis. If the pixel is less
       than or equal to the threshold value, then it is reset to the low output level. If the pixel is greater than the threshold value,  then	it
       is reset to the high output level.

       It uses the following equation:

       srcdst[x][y][i] = glow[i]   if srcdst[x][y][i] <= thresh[i]
       srcdst[x][y][i] = ghigh[i]  if srcdst[x][y][i] > thresh[i]

PARAMETERS
       The function takes the following arguments:

       srcdst	       Pointer to source and destination image.

       thresh	       Threshold value.  thresh[i] contains the threshold for channel i.

       ghigh	       High output level.  ghigh[i] contains the high output level for channel i.

       glow	       Low output level.  glow[i] contains the low output level for channel i.

RETURN VALUES
       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
