NAME
       mlib_ImageZoomIndex - zoom on color-indexed image

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

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

DESCRIPTION
       The mlib_ImageZoomIndex() 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 image data type must be MLIB_BYTE or MLIB_SHORT.

       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_PADDED

       colormap        Internal data structure for inverse color mapping.  This data structure is generated by the mlib_ImageColorTrue2IndexInit()
		       function.

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