mediaLib Library Functions           mlib_ImageZoomIn2X_Fp(3MLIB)



NAME
     mlib_ImageZoomIn2X_Fp - 2X zoom

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

     mlib_status mlib_ImageZoomIn2X_Fp(mlib_image *dst, const mlib_image *src,
          mlib_filter filter, mlib_edge edge);


DESCRIPTION
     The mlib_ImageZoomIn2X_Fp() function enlarges the  floating-
     point  source image by a factor of two. It uses the interpo-
     lation 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:

                 MLIB_NEAREST
                 MLIB_BILINEAR
                 MLIB_BICUBIC
                 MLIB_BICUBIC2



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

                 MLIB_EDGE_DST_NO_WRITE
                 MLIB_EDGE_DST_FILL_ZERO
