mediaLib Library Functions        mlibImageThresh2FpInp(3MLIB)



NAME
     mlibImageThresh2FpInp - image thresholding

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

     mlibstatus mlibImageThresh2FpInp(mlibimage *srcdst,
          const mlibd64 *thresh, const mlibd64 *glow);


DESCRIPTION
     The mlibImageThresh2FpInp() 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 value of the source
     pixel.


     It uses the following equation:

       srcdst[x][y][i] = glow[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.


     glow      Low output level. glow[i] contains the low  output
               level for channel i.


RETURN VALUES
     The function returns MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
