mediaLib Library Functions         mlibImageConstMulShift(3MLIB)



NAME
     mlibImageConstMulShift - multiply  with  a  constant,  with
     shifting

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

     mlibstatus mlibImageConstMulShift(mlibimage *dst, const mlibimage *src,
          const mlibs32 *c, mlibs32 shift);


DESCRIPTION
     The mlibImageConstMulShift() function multiplies each pixel
     in  an  image by a constant value on a pixel-by-pixel basis.
     It scales the result by a right shift and writes the  result
     to the destination image on a pixel-by-pixel basis.


     It uses the following equation:

       dst[x][y][i] = c[i] * src[x][y][i] * 2**(-shift)


PARAMETERS
     The function takes the following arguments:

     dst      Pointer to destination image.


     src      Pointer to source image.


     c        Constant by which each pixel  is  multiplied.  c[i]
              contains the constant for channel i.


     shift    Right shifting factor. 0 < shift < 31.


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