mediaLib Library Functions                  mlib_ImageZoom(3MLIB)



NAME
     mlib_ImageZoom - zoom

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

     mlib_status mlib_ImageZoom(mlib_image *dst, const mlib_image *src,
          mlib_d64 zoomx, mlib_d64 zoomy, mlib_filter filter, mlib_edge edge);


DESCRIPTION
     The mlib_ImageZoom() function will  enlarge  or  minify  the
     source image by the X and Y zoom factors. It uses the inter-
     polation method as described by the resampling filter.


     The data type of the  images  can  be  MLIB_BIT,  MLIB_BYTE,
     MLIB_SHORT, MLIB_USHORT, or MLIB_INT.


     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.


     zoomx     X zoom factor. zoomx > 0.0.


     zoomy     Y zoom factor. zoomy > 0.0.


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

                 MLIB_NEAREST
                 MLIB_BILINEAR

                 MLIB_BICUBIC2



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

                 MLIB_EDGE_DST_FILL_ZERO
                 MLIB_EDGE_OP_NEAREST
                 MLIB_EDGE_SRC_EXTEND
                 MLIB_EDGE_SRC_EXTEND_INDEF
                 MLIB_EDGE_SRC_PADDED



RETURN VALUES
     The function returns MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.
