NAME
mlib_ImageZoomTranslate - zoom, with translation SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageZoomTranslate(mlib_image *dst, const mlib_image *src, mlib_d64 zoomx, mlib_d64 zoomy, mlib_d64 tx, mlib_d64 ty, mlib_filter filter, mlib_edge edge); DESCRIPTION
The mlib_ImageZoomTranslate() function will enlarge or minify the source image by the X and Y zoom factors, with translation. It uses the interpolation method as described by the resampling filter. It uses the following equation for coordinate mapping: xd = zoomx*xs + tx yd = zoomy*ys + ty where a point with coordinates (xs, ys) in the source image is mapped to a point with coordinates (xd, yd) in the destination image. The data type of the images can be MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT. The width and height of the destination image can be different from the width and height of the source image. The center of the upper-left corner pixel of an image is located at (0.5, 0.5). PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. zoomx X zoom factor. zoomx > 0. zoomy Y zoom factor. zoomy > 0. tx X translation. ty Y translation. 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. ATTRIBUTES

NAME
mlib_ImageZoom_Fp - zoom SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageZoom_Fp(mlib_image *dst, const mlib_image *src, mlib_d64 zoomx, mlib_d64 zoomy, mlib_filter filter, mlib_edge edge); DESCRIPTION
The mlib_ImageZoom_Fp() function will enlarge or minify the floating-point source image by the X and Y zoom factors. It uses the interpola- tion 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 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.
