mediaLib Library Functions            mlib_ImageThresh5_Fp(3MLIB)



NAME
     mlib_ImageThresh5_Fp - image thresholding

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

     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  thres-
              hold 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.
