NAME
mlib_ImageZoomTranslateTable_Fp - zoom, with translation, with table-driven interpolation SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageZoomTranslateTable_Fp(mlib_image *dst, const mlib_image *src, mlib_d64 zoomx, mlib_d64 zoomy, mlib_d64 tx, mlib_d64 ty, const void *interp_table, mlib_edge edge); DESCRIPTION
The mlib_ImageZoomTranslateTable_Fp() function will enlarge or minify the floating-point source image by the X and Y zoom factors, with translation. It uses a table, interp_table, to do interpolation. 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_FLOAT or MLIB_DOUBLE. 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. interp_table Pointer to an interpolation table. The table is created by the mlib_ImageInterpTableCreate() function. 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
