mediaLib Library Functions         mlibSignalQuantU8S16(3MLIB)



NAME
     mlibSignalQuantU8S16, mlibSignalQuantU8S16S -  16-bit
     to 8-bit quantization

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

     mlibstatus mlibSignalQuantU8S16(mlibu8 *dst,
          const mlibs16 *src, const mlibs16 *thresh, mlibs32 n);


     mlibstatus mlibSignalQuantU8S16S(mlibu8 *dst,
          const mlibs16 *src, const mlibs16 *thresh, mlibs32 n);


DESCRIPTION
     Each of these functions quantizes a signal  array  by  using
     the following equation:

       X = x(n)  n = 0, 1, ...
       Z = z(n)  n = 0, 1, ...
         =   0   for x(n) < t(0)
         =   k   for t(k) < x(n) < t(k]1)
         = 255   for x(n) > t(255)


PARAMETERS
     Each of the functions takes the following arguments:

     dst       Output signal array.


     src       Input signal array.


     thresh    Array of 256 thresholds.


     n         Number of samples in the input signal array.


RETURN VALUES
     Each of the functions returns  MLIBSUCES  if  successful.
     Otherwise it returns MLIBFAILURE.
