mediaLib Library Functions        mlib_ImageThresh1_Fp_Inp(3MLIB)



NAME
     mlib_ImageThresh1_Fp_Inp - image thresholding

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

     mlib_status mlib_ImageThresh1_Fp_Inp(mlib_image *srcdst,
          const mlib_d64 *thresh, const mlib_d64 *ghigh, const mlib_d64 *glow);


DESCRIPTION
     The mlib_ImageThresh1_Fp_Inp() function compares each  pixel
     in  the floating-point source image to a threshold value, in
     place. 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 high output level.


     It uses the following equation:

       srcdst[x][y][i] = glow[i]   if srcdst[x][y][i] < thresh[i]
       srcdst[x][y][i] = ghigh[i]  if srcdst[x][y][i] > thresh[i]


PARAMETERS
     The function takes the following arguments:

     srcdst    Pointer to source and destination image.


     thresh    Threshold value. thresh[i] contains the  threshold
               for channel i.


     ghigh     High output level. ghigh[i] contains the high out-
               put level 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.
