NAME

       mlib_ImageZoomBlend - image scaling with alpha blending

SYNOPSIS

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

       mlib_status mlib_ImageZoomBlend(mlib_image *dst, const mlib_image *src,
	    mlib_d64 zoomx, mlib_d64 zoomy, mlib_filter filter, mlib_edge edge,
	    mlib_blend blend, mlib_s32 alpha, mlib_s32 cmask);

DESCRIPTION

       The  mlib_ImageZoomBlend()  function  will enlarge or minify the source image by the X and Y zoom factors and blend it with the destination
       image.

       This function is a special case of mlib_ImageZoomTranslateBlend() with the center of the source image being mapped to  the  center  of  the
       destination image.

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

       Both src and dst must be of type MLIB_BYTE. They can have either 3 or 4 channels.

       The src image cannot have width or height larger than 32767.

PARAMETERS

       The function takes the following arguments:

       dst	 Pointer to destination image.

       src	 Pointer to first 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

       blend	 Type of alpha blending. It can be one of the following:

		   MLIB_BLEND_GTK_SRC
		   MLIB_BLEND_GTK_SRC_OVER
		   MLIB_BLEND_GTK_SRC_OVER2

       alpha	 Overall alpha for blending.

       cmask	 Channel mask to indicate the alpha channel.

RETURN VALUES

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

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.
