mediaLib Library Functions               mlibImageMeanFp(3MLIB)



NAME
     mlibImageMeanFp - image mean

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

     mlibstatus mlibImageMeanFp(mlibd64 *mean, const mlibimage *img);


DESCRIPTION
     The mlibImageMeanFp() function computes the mean value  of
     all the pixels in the image.


     It uses the following equation:

                   1     w-1 h-1
       mean[i] = ----- * SUM SUM img[x][y][i]
                  w*h    x=0 y=0


PARAMETERS
     The function takes the following arguments:

     mean    Pointer to mean array, where length is the number of
             channels  in the image. mean[i] contains the mean of
             channel i.


     img     Pointer to an image.


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