NAME
     mlib_ImageThresh2 - image thresholding

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlib_status mlib_ImageThresh2(mlib_image *dst, const mlib_image *src,
          const mlib_s32 *thresh, const mlib_s32 *glow);


DESCRIPTION
     The mlib_ImageThresh2() 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 low output level. If the pixel is greater than
     the threshold value, then the destination pixel  is  set  to
     the value of the source pixel.


     It uses the following equation:

       dst[x][y][i] = glow[i]       if src[x][y][i] < thresh[i]
       dst[x][y][i] = src[x][y][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.


     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.
