mlib_ImageInterpTableDelete - deletes an interpolation table
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
void mlib_ImageInterpTableDelete(void *interp_table);
DESCRIPTION
The mlib_ImageInterpTableDelete() function deletes an interpolation table.
This function deletes the structure of an interpolation table and frees the memory allocated by mlib_ImageInterpTableCreate().
PARAMETERS
The function takes the following arguments:
interp_table Pointer to an interpolation table.
RETURN VALUES
None.

mlib_ImageAffineTable - affine transformation on an image with table-driven interpolation
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageAffineTable(mlib_image *dst, const mlib_image *src, const mlib_d64 *mtx, const void *interp_table, mlib_edge edge);
DESCRIPTION
The mlib_ImageAffineTable() function does affine transformation on an image with table-driven interpolation.
The following equation represents the affine transformation:
xd = a*xs + b*ys + tx
yd = c*xs + d*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_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.
mtx Transformation matrix. mtx[0] holds a; mtx[1] holds b; mtx[2] holds tx; mtx[3] holds c; mtx[4] holds d; mtx[5] holds ty.
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_PADDED
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
