NAME
       mlib_ImageThresh3 - image thresholding

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

       mlib_status mlib_ImageThresh3(mlib_image *dst, const mlib_image *src, const mlib_s32 *thresh, const mlib_s32 *ghigh);

DESCRIPTION
       The  mlib_ImageThresh3()  function  compares each pixel in the source image to a threshold value. If the pixel is less than or equal to the
       threshold value, then the destination pixel is set to the value of the source pixel. If the pixel is greater than the threshold value, then
       the destination pixel is set to the high output level.

       It uses the following equation:

       dst[x][y][i] = src[x][y][i]  if src[x][y][i] <= thresh[i]
       dst[x][y][i] = ghigh[i]	    if src[x][y][i] > thresh[i]

PARAMETERS
       The function takes the following arguments:

       dst	       Pointer to destination image.

       src	       Pointer to source 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.

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