NAME
     mlib_ImageThresh2_Fp - image thresholding

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

     mlib_status mlib_ImageThresh2_Fp(mlib_image *dst, const mlib_image *src,
          const mlib_d64 *thresh, const mlib_d64 *glow);


DESCRIPTION
     The mlib_ImageThresh2_Fp() function compares each  pixel  in
     the floating-point 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 destina-
     tion 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.
