mediaLib Library Functions             mlibImageZoomOut2X(3MLIB)



NAME
     mlibImageZoomOut2X - 0.5X zoom

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

     mlibstatus mlibImageZoomOut2X(mlibimage *dst, const mlibimage *src,
          mlibfilter filter, mlibedge edge);


DESCRIPTION
     The mlibImageZoomOut2X() function minifies the source image
     by  a  factor  of  two.  It uses the interpolation method as
     described by the resampling filter.


     The center of the upper-left corner pixel  of  an  image  is
     located at (0.5, 0.5).


     The width and height of the destination image  can  be  dif-
     ferent from those of the source image.


     The center of the source image is mapped onto the center  of
     the destination image.

PARAMETERS
     The function takes the following arguments:

     dst       Pointer to destination image.


     src       Pointer to source image.


     filter    Type of resampling filter. It can be  one  of  the
               following:

                 MLIBNEAREST
                 MLIBILINEAR
                 MLIBICUBIC
                 MLIBICUBIC2



     edge      Type of edge condition. It can be one of the  fol-
               lowing:
