NAME
       mlib_ImageThresh5_Fp - image thresholding

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

       mlib_status  mlib_ImageThresh5_Fp(mlib_image  *dst,  const  mlib_image  *src,  const  mlib_d64 *thigh, const mlib_d64 *tlow, const mlib_d64
       *gray);

DESCRIPTION
       The mlib_ImageThresh5_Fp() function compares each pixel in the source image to two threshold values, tlow and thigh. If	the  pixel  is	in
       between	the  lower  threshold value, tlow, and the higher threshold value, thigh, (inclusive on both sides), then the destination pixel is
       set to the value gray. Otherwise, the destination pixel is set to the value of the source pixel.

       It uses the following equation:

       dst[x][y][i] = src[x][y][i]  if src[x][y][i] < tlow[i]
       dst[x][y][i] = gray[i]	    if tlow[i] <= src[x][y][i] <= thigh[i]
       dst[x][y][i] = src[x][y][i]  if src[x][y][i] > thigh[i]

PARAMETERS
       The function takes the following arguments:

       dst	       Pointer to destination image.

       src	       Pointer to source image.

       thigh	       High threshold value.  thigh[i] holds the high threshold for channel i.

       tlow	       Low threshold value.  tlow[i] holds the low threshold for channel i.

       gray	       Output grayscale level.	gray[i] holds the output grayscale level for channel i.

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