NAME
       mlib_ImageZoom - zoom

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       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 interpolation 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 different 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_BICUBIC
		   MLIB_BICUBIC2

       edge	 Type of edge condition. It can be one of the following:

		   MLIB_EDGE_DST_NO_WRITE
		   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.
